4. Anatomy of the Uterus
• The uterus, also known as the
womb, is a pear-shaped, hollow
organ located in the female pelvis. It
is a crucial component of the female
reproductive system and plays a
central role in menstruation,
pregnancy, and childbirth. Let's
explore its anatomy in detail:

5. Structure and Position
• The uterus is situated between the urinary bladder
(anteriorly) and the rectum (posteriorly).
• It is held in place by several ligaments, including
the broad ligament, round ligaments, and uterosacral
ligaments.
• The uterus is divided into three main parts: the
fundus (uppermost part), the body (central part), and
the cervix (lower narrow part).

6. Layers of the Uterus
The uterus has three primary layers, each with specific functions:
• a. Perimetrium: The outermost layer of the uterus, consisting of a thin serous
membrane that covers the organ's surface. This layer helps to protect and support the
uterus.
• b. Myometrium: The middle and thickest layer, made up of smooth muscle tissue. The
myometrium is responsible for the strong contractions of the uterus during labor and
delivery. It also helps in expelling menstrual blood during menstruation.
• c. Endometrium: The innermost layer, composed of glandular tissue and blood vessels.
The endometrium is richly supplied with blood and undergoes cyclic changes during
the menstrual cycle. If pregnancy occurs, the endometrium provides a suitable
environment for the implantation of a fertilized embryo.

7. • Uterine Cavity: The uterine cavity is the space inside the uterus, where a
fertilized egg can implant and develop into a fetus during pregnancy. The cavity
is continuous with the cervical canal, which connects to the vagina.
• Blood Supply: The uterus receives its blood supply from two main arteries:
• Uterine arteries: Branches of the internal iliac arteries that provide oxygenated
blood to the uterus.
• Ovarian arteries: Arise from the abdominal aorta and supply blood to the ovaries,
fallopian tubes, and parts of the uterus.
• Innervation: The uterus is innervated by both sympathetic and parasympathetic
nerves from the autonomic nervous system. These nerves control the contractions
of the uterus during labor and delivery.

9. Functions of the Uterus
• Menstruation: The endometrial lining of the uterus sheds during
menstruation when pregnancy does not occur.
• Pregnancy: If fertilization occurs, the uterus provides a suitable
environment for the implantation and development of the embryo.
• Labor and Delivery: During labor, the myometrium contracts to push the
fetus out through the cervix and vagina.

10. Variations and Anomalies
• Bicornuate uterus: Some women may have a congenital anomaly
where the uterus has a heart-shaped appearance due to incomplete
fusion during development.
• Uterine fibroids: Non-cancerous growths in the myometrium that can
cause symptoms like heavy menstrual bleeding and pelvic pain.

11. Anatomy of the Ovaries
• The ovaries are a pair of small, oval-
shaped organs located on either side
of the female pelvis. They are
essential components of the female
reproductive system and play a
crucial role in hormone production,
ovulation, and fertility.
31/07/2023 Anatomy of General Gynecology By- Dheeraj Kumar 11

12. Location and Position
• The ovaries are situated in the lower
abdomen, on either side of the uterus,
near the opening of the fallopian tubes.
• They are held in place by ligaments,
including the ovarian ligament,
suspensory ligament of the ovary, and
broad ligament.
31/07/2023 Anatomy of General Gynecology By- Dheeraj Kumar 12

13. Structure
• Each ovary is approximately the size of an almond and measures about 3-5
centimetres in length.
• The outer surface of the ovary is covered by a layer of simple cuboidal epithelium
known as the germinal epithelium.
• Beneath the germinal epithelium lies the ovarian cortex, which contains the
majority of ovarian structures.
• The central part of the ovary is called the ovarian medulla, consisting of
connective tissue, blood vessels, and nerves.
31/07/2023 Anatomy of General Gynecology By- Dheeraj Kumar 13

14. Ovarian Follicles
• The ovarian cortex contains numerous structures called
ovarian follicles. Each follicle consists of an immature
egg (oocyte) surrounded by specialized cells known as
granulosa cells.
• Ovarian follicles go through various stages of
development, starting from primordial follicles (the
most basic form) to mature Graafian follicles (ready for
ovulation).
• During each menstrual cycle, one follicle becomes
dominant and matures to release an egg during
ovulation.
31/07/2023 Anatomy of General Gynecology By- Dheeraj Kumar 14

15. Ovulation
• Ovulation is the process by which a mature
egg is released from the ovary into the
fallopian tube, where it can be fertilized by
sperm.
• The ruptured ovarian follicle after ovulation
is known as the corpus luteum, which plays
a crucial role in producing progesterone to
support a potential pregnancy.
31/07/2023 Anatomy of General Gynecology By- Dheeraj Kumar 15

16. Blood Supply and Innervation
• The ovaries receive their blood supply
from the ovarian arteries, which branch
off from the abdominal aorta.
• Innervation of the ovaries comes from
both the sympathetic and
parasympathetic divisions of the
autonomic nervous system.
31/07/2023 Anatomy of General Gynecology By- Dheeraj Kumar 16

17. Functions of the Ovaries
• Egg Production: The ovaries produce and release eggs (oocytes)
during the menstrual cycle, allowing for potential fertilization.
• Hormone Production: The ovaries produce hormones, including
oestrogen and progesterone, which play essential roles in regulating
the menstrual cycle, supporting pregnancy, and maintaining overall
reproductive health.
31/07/2023 Anatomy of General Gynecology By- Dheeraj Kumar 17

18. Hormonal Regulation
• Hormonal regulation of the ovaries is coordinated by the hypothalamus,
pituitary gland, and the ovaries themselves.
• The hypothalamus releases gonadotropin-releasing hormone (GnRH),
which stimulates the pituitary gland to release follicle-stimulating hormone
(FSH) and luteinizing hormone (LH).
• FSH and LH, in turn, stimulate the growth and maturation of ovarian
follicles, leading to ovulation.
31/07/2023 Anatomy of General Gynecology By- Dheeraj Kumar 18

19. Menopause
• As women age, the number and quality of ovarian follicles decline,
leading to menopause, which marks the end of reproductive capacity.
• During menopause, oestrogen and progesterone levels decrease,
leading to various physical and hormonal changes in the body.
31/07/2023 Anatomy of General Gynecology By- Dheeraj Kumar 19

20. Fallopian Tubes
• The fallopian tubes, also known as uterine tubes or oviducts, are a pair of slender, tubular structures that
connect the ovaries to the uterus in the female reproductive system. They play a vital role in fertilization, as
well as in the transport of eggs (oocytes) from the ovaries to the uterus. Let's explore their anatomy in detail:
• Structure and Location:
• There are two fallopian tubes, one on each side of the uterus. Each tube is about 10 to 12 centimetres long.
• The fallopian tubes extend laterally from the superior corners of the uterus, forming a connection with the
ovaries.
• They are held in place by the broad ligament, which is a fold of peritoneum that supports and encloses the
reproductive organs.
31/07/2023 Anatomy of General Gynecology By- Dheeraj Kumar 20

21. Regions of the Fallopian Tubes
• The fallopian tubes are divided into four main regions:
• a. Infundibulum: The funnel-shaped, distal end of each fallopian tube that lies
closest to the ovary. It has finger-like projections called fimbriae that help capture
the released egg during ovulation.
• b. Ampulla: The widest and longest part of the fallopian tube, located between the
infundibulum and the isthmus. The ampulla is the most common site for
fertilization to occur.
• c. Isthmus: A narrower region of the fallopian tube located closer to the uterus. It
serves as a conduit for transporting fertilized eggs from the ampulla to the uterine
cavity.
• d. Interstitial (Intramural) Part: The short segment of the fallopian tube that
penetrates the uterine wall and opens into the uterine cavity. This part is entirely
within the thickness of the uterine wall.
31/07/2023 Anatomy of General Gynecology By- Dheeraj Kumar 21

22. Structure of the Fallopian Tube Wall
• The fallopian tube wall consists of three layers:
a. Mucosa: The innermost layer lined with ciliated
columnar epithelium. The cilia play a crucial role in
propelling the egg towards the uterus and assisting in the
movement of sperm towards the egg.
b. Muscularis: The middle layer composed of smooth
muscle tissue. This layer contracts rhythmically to help
move the egg through the tube.
c. Serosa: The outermost layer covered by a serous
membrane that is continuous with the peritoneum.
31/07/2023 Anatomy of General Gynecology By- Dheeraj Kumar 22

23. Egg Transport and Fertilization
• After ovulation, the fallopian tubes pick up the
released egg from the ovary using the fimbriae.
• Ciliary movement and peristalsis (muscular
contractions) within the fallopian tubes help
transport the egg towards the uterus.
• If sperm are present in the fallopian tubes after
sexual intercourse, fertilization of the egg by
sperm usually occurs within the ampulla of the
fallopian tube.
31/07/2023 Anatomy of General Gynecology By- Dheeraj Kumar 23

24. Ectopic Pregnancy
• Ectopic pregnancy is a condition
where a fertilized egg implants outside
the uterine cavity, most commonly in
the fallopian tubes.
• An ectopic pregnancy is a medical
emergency, as it can lead to life-
threatening complications if not
diagnosed and treated promptly.

25. Vagina
• The vagina is a muscular, tubular structure that forms
part of the female reproductive system. It is located
between the external genitalia (vulva) and the cervix
of the uterus. Here's a brief overview of the anatomy
of the vagina:
• Structure: The vagina is a flexible, fibromuscular
canal that extends from the vaginal opening
(introitus) at the external genitalia to the cervix of the
uterus.
31/07/2023 Anatomy of General Gynecology By- Dheeraj Kumar 25

26. Layers of the Vaginal Wall
• Mucosa: The innermost layer, covered with
stratified squamous epithelium, which helps protect
the underlying tissues.
• Muscularis: The middle layer composed of smooth
muscle that allows the vagina to stretch during
sexual activity and childbirth.
• Adventitia: The outermost layer made up of fibrous
connective tissue that supports and anchors the
vagina to surrounding structures.
31/07/2023 Anatomy of General Gynecology By- Dheeraj Kumar 26

27. Functions
• Sexual Intercourse: The vagina serves as the receptacle for the penis
during sexual intercourse.
• Birth Canal: During childbirth, the baby passes through the vagina as
it exits the uterus and enters the world.
• Menstrual Flow: The vagina allows menstrual blood and uterine
secretions to exit the body during menstruation.
31/07/2023 Anatomy of General Gynecology By- Dheeraj Kumar 27

28. • pH and Microbiota: The vagina has a slightly acidic pH, which is maintained by
beneficial bacteria (Lactobacilli). These bacteria help prevent the overgrowth of
harmful microorganisms and maintain a healthy vaginal environment.
• Elasticity: The vaginal walls are highly elastic, which allows the vagina to
accommodate various sizes, such as during sexual intercourse and childbirth, and
then return to its original shape.
• Nerve Supply: The vagina is richly supplied with sensory nerves, making it
sensitive to touch and stimulation.

29. Menstrual Cycle
• Explanation of the menstrual cycle and its phases: The
menstrual cycle is a monthly hormonal process that prepares
the body for pregnancy. It typically consists of four phases:
menstruation, follicular phase, ovulation, and luteal phase.
• Hormonal changes during each phase: Describe the role of
hormones, such as estrogen and progesterone, in regulating
the menstrual cycle and preparing the body for conception.
• Common menstrual disorders and their management: Discuss
disorders like irregular periods, dysmenorrhea (painful
periods), and amenorrhea (absence of periods), along with
their potential causes and treatment options.

33. Summary of Anatomy of General Gynecology
• General Gynecology encompasses the study of the female reproductive system and its associated structures. Key
anatomical components include the uterus, ovaries, fallopian tubes, vagina, and external genitalia (vulva).
• The uterus is a pear-shaped organ with three layers: Perimetrium, myometrium, and endometrium. It plays a central
role in menstruation, pregnancy, and childbirth. The ovaries are paired organs responsible for egg production and
hormone production (estrogen and progesterone).
• The fallopian tubes connect the ovaries to the uterus and serve as pathways for egg transport and fertilization. The
vagina is a muscular canal that acts as the birth canal during childbirth and facilitates sexual intercourse.
Understanding the anatomy of general Gynecology is crucial for medical students to diagnose and manage various
gynecological conditions, promote women's reproductive health, and provide comprehensive care to female patients.
