The uterine wall consists of three layers: the endometrium, myometrium, and perimetrium. The endometrium undergoes cyclic changes during the menstrual cycle in response to hormones from the ovaries. It has two layers - a functional layer that is shed during menstruation and a basal layer that remains. The menstrual cycle involves the maturation and release of an egg, and hormonal changes produced by the ovaries cause the endometrium to cycle between phases of proliferation and secretion. If fertilization does not occur, the corpus luteum degenerates and menstruation begins as the endometrium enters an ischemic phase and is shed.

Ovarian & uterine_cycles
This document summarizes the ovarian and uterine cycles in women. It describes how the hypothalamus and pituitary gland regulate hormone production, including follicle-stimulating hormone and luteinizing hormone, which stimulate changes in the ovaries and uterus. These include follicle development, ovulation, formation of the corpus luteum, and changes to the endometrium under the influence of estrogen and progesterone in a typical 28-day cycle. Fertilization results in implantation and continuation of the corpus luteum and menstrual cycle. Non-fertilization leads to menstruation.
Hormonal Control Of Ovarian And Endometrial Cycles
The document summarizes the ovarian and endometrial cycles. The ovarian cycle involves the development and release of oocytes over approximately 28 days and consists of the follicular and luteal phases regulated by hormones. The endometrial cycle involves preparation of the uterus for implantation over around 28 days and consists of the menstrual, proliferative, and secretory phases regulated by hormones. Key hormones such as FSH, LH, estrogen, and progesterone regulate growth and shedding of the endometrium corresponding to changes in the ovaries.
Menstrual cycle
The menstrual cycle involves cyclic changes in the ovaries, uterus, cervix and vagina over approximately 28 days. It begins at menarche and consists of two phases - the follicular phase where an ovarian follicle develops and ovulation occurs, and the luteal phase where the corpus luteum forms. If pregnancy does not occur, the thickened uterine lining is shed through menstruation marking the start of a new cycle. The cycle involves changes in hormone levels, the development and breakdown of tissues, and variations in the cervix and vaginal environment to prepare for potential pregnancy.
Menstrual cycle 2
The menstrual cycle is a series of physiological changes in fertile women controlled by the endocrine system necessary for reproduction. On average it is 28 days but varies in length. It begins at menarche around age 12 and ends at menopause typically between ages 45-55. The cycle involves changes in the neuroendocrine system, ovaries, and uterus. It consists of the menstrual, proliferative/follicular, and secretory/luteal phases characterized by menstrual bleeding, thickening of the endometrium, ovulation, and preparation for potential implantation. Abnormalities can include problems with ovulation, irregular or abnormal bleeding.
Menstrual cycle
The menstrual cycle is the series of changes that occur in a woman's reproductive system, under the control of hormones. It typically lasts around 28 days and has three phases: the menstrual phase where the uterine lining sheds, the proliferative phase where the lining grows under rising estrogen, and the secretory phase where progesterone rises and peaks at ovulation, after which the cycle begins again if conception does not occur. The cycle is essential for reproduction and generally begins at menarche in early teenage years before ending at menopause in middle age.
MENSTRUAL CYCLE.pptx
The menstrual cycle occurs monthly in women of reproductive age. It involves changes in the endometrium and ovaries over approximately 28 days. During the first half, the ovaries release hormones that cause the endometrium to thicken in preparation for a potential pregnancy. Around day 14, ovulation occurs where an egg is released. If pregnancy does not occur, hormone levels drop and the endometrium sheds its lining through menstruation. Precise timing of ovulation allows planning for or preventing pregnancy.

Menstrual cycle
The menarche is one of the later stages of puberty in girls. The first period is called menarche . The average age of menarche in humans in 12years, but is normal anywhere between ages 8-16.
A number of physical and psychological changes take place at puberty:- The uterus , the uterine tubes and the ovaries reach maturity.
The menstrual cycle and ovulation begin {menarche},The breast develop and enlarge,Pubic and auxiliary hair begins to grow, Increases in height and widening of the pelvis. Increased fat deposited in the subcutaneous tissue especially at the hips and breasts. The cessation of menstrual cycles at the end of a woman's reproductive life is termed menopause. The average age of menopause in women is 51 years, with anywhere between 40-58 being common.
Menstruation is the periodic discharge of blood and sloughed endometrium (collectively called menses or menstrual flow) through the vagina.
The menstrual cycle is the regular natural change that occur in the female reproductive system (specially the ovaries and uterus) that makes pregnancy possible. This cycle is controlled by hormones, The menstrual cycle occurs because of a complex relationship between hormones from the brain and ovaries. This leads to the development and release of an egg from the ovary (ovulation) and growth of the internal lining (endometrium) of the uterus, to prepare it for pregnancy
Menarche is the first menstrual cycle, or first menstrual bleeding, in female human beings.
The average age of menarche is 11.75 years.
Menopause is the permanent cessation of menses.
Menopause typically (but not always) occurs in women during their late 40s or early 50s, and signals the end of the fertile phase of a woman's life.

Reproductive System Female.ppt
The female reproductive system consists of internal and external organs. The internal organs include the ovaries, fallopian tubes, uterus, and vagina. The ovaries produce eggs and hormones, the fallopian tubes transport eggs to the uterus, and the uterus nourishes a fetus during pregnancy. The external organs include the vulva and breasts. The reproductive cycle involves ovarian and menstrual cycles, which regulate egg production and the uterine lining. Hormones like estrogen and progesterone control the cycles.
Menstruation
This document provides information on the menstrual cycle including its definition, typical duration, and the ovarian and uterine cycles. It describes in detail the follicular phase of the ovarian cycle including the development of primordial follicles into preantral and preovulatory follicles.

This document provides a histological overview of the female reproductive system. It describes the main tissues and structures, including the ovaries, oviducts, uterus, vagina, external genitalia, and mammary glands. It details the layers of the uterus and changes that occur in the endometrium over the menstrual cycle. It also summarizes the types of ovarian follicles from primordial to mature follicles, and the formation and function of the corpus luteum. Following ovulation, the formation of the placenta allows for nutrient exchange between mother and fetus.
Menstruation
The menstrual cycle involves monthly changes in the female reproductive system. Upon reaching puberty, girls begin to menstruate as the uterus sheds its lining for 5 days each month. During the cycle, follicles in the ovaries mature and eventually rupture to release an egg (ovulation) around day 14. If the egg is not fertilized, hormone levels fall and the uterine lining is shed, starting a new cycle. The average menstrual cycle is 28 days and menstruation typically begins at puberty.
04-Menstruation-Ovulation-DrSuresh.pptx
Menstruation is caused by shedding of the uterine endometrium due to falling levels of estrogen and progesterone at the end of each menstrual cycle. It is indicative of ovarian events controlled by the hypothalamic-pituitary axis. The menstrual cycle involves both an ovarian cycle and an endometrial cycle regulated by hormones. In the ovarian cycle, follicles develop under the influence of FSH, with one follicle becoming dominant and ovulating due to an LH surge. The ruptured follicle forms the corpus luteum which produces progesterone and estrogen to prepare the endometrium. If implantation does not occur, progesterone and estrogen levels fall, causing menstruation and starting a new cycle.

MENSTRUAL CYCLE AND OVULATION 04-09-23 dr.Aremu.ppt
The document discusses the menstrual cycle in women. It defines the menstrual cycle and explains that it typically occurs monthly from puberty to menopause. The cycle involves changes in the ovaries and uterus regulated by hormones. It describes the four phases - follicular, ovulation, luteal, and menstrual. Key events like menarche, ovulation and menstruation are explained. Causes and symptoms of common conditions like PMS and dysmenorrhea are also summarized.
Normal physiology of female reproductive system
1) The document discusses the normal physiology of the female reproductive system, including oogenesis and follicular development where approximately 1-2 million primary oocytes are present at birth and only 400-500 fully mature each month.
2) It describes the hormonal physiology and monthly cycle, influenced by hormones like FSH, LH, estrogens, and progesterone. Ovulation occurs around day 14 before menstruation.
3) The functions of estrogen and progesterone are outlined, such as estrogen's effects on development of the uterus, breasts, and external sex organs during puberty, and progesterone's role in preparing the uterus for potential implantation.
Endo Repro Anatomy and Histology
The female reproductive system produces eggs and provides an environment for fertilization and embryo development. The ovaries contain primordial follicles which mature through various stages in response to hormones. Most follicles undergo atresia, while one becomes dominant and ovulates monthly. The released egg is transported by the uterine tubes to the uterus. If fertilized, it implants and the placenta develops to support fetal growth. The endometrium thickens monthly under hormonal control but is shed as menstruation if implantation does not occur.
Human female reproductive system
The female reproductive system has several important functions including producing egg cells for reproduction and sex hormones. It consists of both external and internal organs working together. The internal organs include ovaries, fallopian tubes, uterus, and vagina. During puberty, girls experience physical changes in these organs and their development. The menstrual cycle and pregnancy occur through the coordinated efforts of the reproductive system. Diseases can also affect the system's normal physiology.

5 Female Reproductive System.pdf
The female reproductive system includes the ovaries, oviducts, uterus, vagina, and external genitalia. The ovaries produce eggs and female sex hormones. The oviducts and uterus provide sites for fertilization, implantation, and nourishment of a fetus during pregnancy. The hypothalamus and pituitary gland regulate female reproduction through secretion of gonadotropins and sex hormones. The ovarian and menstrual cycles are regulated by these hormones and involve follicular development, ovulation, changes to the endometrium, and menstruation if fertilization does not occur.
Menstrual Cycle
The menstrual cycle involves coordinated changes in the ovaries and uterus driven by hormones. It typically lasts 28 days and includes a follicular phase where an egg matures and is released, ovulation, and a luteal phase where the corpus luteum develops. Hormones like FSH, LH, estrogen and progesterone regulate this cycle. The endometrium thickens during the follicular phase in response to rising estrogen, and further changes during the luteal phase due to progesterone to prepare for potential implantation. If implantation does not occur, hormone levels drop and the endometrium is shed as menstruation.
MENSTRUAL CYCLE.pptx
The menstrual cycle involves cyclic changes in the ovaries and uterus that occur over approximately 28 days. It begins at menarche between ages 12-15 and ends at menopause around ages 45-50. The cycle consists of a follicular phase where an egg matures and is released, an ovulation phase where the egg is released, and a luteal phase where the endometrium is prepared for potential implantation. Hormone levels of estrogen and progesterone rise and fall over the course of the cycle to regulate these changes until menstruation begins again if implantation does not occur.
menstrualcycle-090614135948-phpapp01.pdf
The menstrual cycle typically lasts 28 days and involves changes in the uterine lining. It begins with menstruation where the uterine lining is shed. During the proliferative phase, the lining thickens in response to rising estrogen levels. Around day 14, LH surges and causes ovulation where an egg is released. Following ovulation, the secretory phase begins where progesterone levels rise, preparing the uterine lining in case of fertilization. If no fertilization occurs, hormone levels drop and menstruation begins, restarting the cycle.

It describes how to mark the hip joint, knee joint, femoral artery, popliteal artery, dorsal pedis artery, femoral vein, long saphenous vein, femoral nerve, sciatic nerve, tibial nerve, common peroneal nerve and deep peroneal nerve. For each structure, it lists the anatomical landmarks to mark and connects them with lines to indicate the path of the structure.
05 FEMORAL-TRIANGLE.pptx
The femoral triangle is bounded superiorly by the inguinal ligament, laterally by the sartorius muscle, and medially by the adductor longus muscle. It contains the femoral nerve, femoral vessels, and lymph nodes. The adductor canal deep to the sartorius contains the femoral vessels and saphenous nerve. The femoral sheath encloses the femoral artery laterally, femoral vein medially, and femoral canal medially containing loose tissue and lymph nodes. Femoral hernias occur through the femoral ring in the canal.
INTRODUCTION TO NERVE FIBRE.pptx
Nerve fibres, also known as neurons, are specialized cells that transmit electrical and chemical signals between the brain and other parts of the body. They are classified into three main types - A, B and C fibres - based on their diameter, function and conduction velocity. A fibres are myelinated and conduct signals rapidly, while C fibres are thinly myelinated or unmyelinated and conduct signals slowly.
AORTA 2.pptx
1. The document describes the major parts of the aorta including the ascending aorta, arch of aorta, descending aorta, and abdominal aorta.
2. It provides details on the branches of the ascending aorta including the right and left coronary arteries.
3. The arch of aorta is described along with its branches - the brachiocephalic artery, left common carotid artery, and left subclavian artery.
FIRST WEEK OF DEVELOPMENT.pptx
1. Fertilization involves the fusion of an egg and sperm, forming a zygote with a full set of chromosomes. The zygote then undergoes cleavage, forming a morula by day 3 and a blastocyst by day 5 as it travels down the fallopian tube.
2. The blastocyst implants in the uterine wall around 1 week after fertilization. The trophoblast cells of the blastocyst initiate implantation and will later form the placenta, while the inner cell mass gives rise to the embryo.
3. During the first week, the zygote develops from a single cell through cleavage, compaction, blastulation and begins implantation in the uterus.
cartilage.pptx
Cartilage is a tough, flexible connective tissue composed of chondrocytes embedded in an extracellular matrix containing glycosaminoglycans, proteoglycans, collagen and elastic fibers. There are three main types of cartilage - hyaline cartilage, fibrocartilage, and elastic cartilage - which are classified based on the composition of their extracellular matrix and the cells present. All cartilages lack blood vessels, lymphatics and nerves, and contain hyaluronic acid, proteoglycans, glycoproteins and collagen fibers.
ovulation.pptx
The ovarian cycle begins with several follicles growing under the influence of FSH. One follicle matures and its surrounding cells produce estrogen. At mid-cycle, an LH surge causes ovulation of the oocyte from the mature follicle. After ovulation, the remaining cells of the follicle become vascularized and form the corpus luteum, which secretes progesterone. Progesterone prepares the uterus for potential implantation if fertilization occurs. If implantation does not occur, progesterone levels drop and menstruation begins.

By Dr. Vinod Kumar KanvariaLAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

uterine cycle.pptx
- 3. The uterine wall • Endometrium • Myometrium • Perimetrium
- 5. Endometrium • Undergoes hormone modulated cyclic changes during different phases of the menstrual cycle
- 6. Layers of the endometrium • Functional layer • Basal layer
- 7. • The menstrual cycle is the period during which -- the oocyte matures --the oocyte is ovulated --the oocyte enters the uterine tube
- 8. • The hormones produced by the ovarian follicles and corpus luteum (estrogen and progesterone) produce cyclic changes in the endometrium
- 10. • The endometrium is a “mirror” of the ovarian cycle
- 11. • The average menstrual cycle is 28 days (23-35 days) with day 1 of the cycle designated as the day on which menstrual flow begins
- 13. Phases of menstrual cycle 1. Menstrual phase 2. Proliferative phase 3. Luteal phase 4. Ischemic phase 5. Pregnancy phase
- 14. Menstrual phase • The functional layer of the uterine wall is sloughed off and discarded with the menstrual flow which lasts 4-5 days • Blood + endometrial tissue • Eroded endometrium is thin
- 15. Proliferative phase • Follicular phase, estrogenic: lasts about 9 days • Coincides with the growth of ovarian follicles and is controlled by estrogen secreted by these follicles • 2 to 3 fold increase in the thickness of the endometrium
- 16. Cont: • Phases of repair and proliferation • Surface epithelium reforms and covers the endometrium • The gland increase in number and length • The spiral arteries elongate
- 17. Luteal phase • Secretory: lasts 13 days • Coincides with the formation, functioning and growth of corpus luteum • Glands become wide, tortuous and saccular • Endometrium thickens because of the influence of progesterone and estrogen
- 19. If fertilization does not occur • Corpus luteum degenerates • Decreased estrogen and progesterone • Secretory endometrium enters an ischemic phase • Menstruation occurs
- 20. Ischemic phase • Occurs when oocyte is not fertilized • Spiral arteries constrict, giving the endometrium a pale appearance • Loss of 20-80 ml of blood • Menstruation lasts 3-5 days
