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.

This document discusses the different types of cartilage in the body. It begins by defining cartilage as a smooth, elastic tissue that cushions and protects joints. There are three main types of cartilage - hyaline, elastic, and fibrocartilage. Each type has a unique extracellular matrix and cellular structure that determines its location and function. Hyaline cartilage is found at the ends of bones and provides protection and support for movable joints. Elastic cartilage is present in the external ear and parts of the larynx, providing flexible support. Fibrocartilage acts as a shock absorber and is located in intervertebral discs, knees, and pubic symphysis. The document also briefly discusses some pathological conditions that affect cartilage.
Histology of Connective Tissue.pptx
Connective tissue is the tissue that connects or separates, and supports all the other types of tissues in the body. Like all tissue types, it consists of cells surrounded by a compartment of fluid called the extracellular matrix (ECM). However connective tissue differs from other types in that its cells are loosely, rather than tightly, packed within the ECM.
Connective tissue slides
Connective tissue functions to bind, support, and strengthen organ systems. It protects internal organs, compartmentalizes structures, transports materials, stores energy, and participates in immune responses. Connective tissue consists of cells separated by an extracellular matrix of ground substance and fibers. The matrix contains collagen, elastic, and reticular fibers that provide strength and flexibility. Cells include fibroblasts that secrete fibers, immune cells, fat cells, and other specialized cells. Connective tissue is classified by location and composition into loose, dense, cartilage, bone, and blood or lymph varieties.

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.
uterine cycle.pptx
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.
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.

LAND 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
9
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.
