Epithelial tissue always rests on a basement membrane. The characteristics are: lack of visible interstitial space‚ many cells‚ and no blood vessels. A. Simple Squamous: (kidney slide). Look in the outer edge or cortex of the kidney to find a Bowman’s capsule. The lining of the Bowman’s

different tissue types. Epithelial tissue is a sheet of cells that covers a body surface or lines a body cavity. For example‚ epithelial tissue can be found in the stomach. There are two different types of epithelial tissue; simple and stratified. The simple epithelial has a single cell layer‚ whilst the stratified epithelial consist of two or more cell layers stacked on top of one another. They are tightly packed tissues and the two types can be seen in the image below. Epithelial tissues have two

Ovarian cancer can develop from the epithelial cells surrounding the ovary‚ the germ cells‚ or stromal cells within it. Epithelial ovarian carcinomas account for 85-90% of ovarian cancers‚ and will be the focus of this essay. Most symptoms of epithelial ovarian cancer are due to the fact that it often spreads to the lining of and organs in the abdominal cavity. These symptoms include bloating‚ pelvic or abdominal pain‚ urinary urgency or frequency‚ and trouble eating associated with feeling of fullness

Principal tissues in the human body Colorado Christian University Human Anatomy/Physiology BIO201A Principal tissues in the human body The human body is contains four main tissue types. Tissues are a group of similar cells‚ formed in the embryo‚ that perform a specific function or group of functions. According to Patton and Thibodeau (2013)‚ “There are four major or principal tissue types: epithelial‚ connective‚ muscle‚ and nervous” (p. 8). Each of these tissue types differ in the roles

four major tissues in the human body. One of the major tissues is the epithelial issue that covers the surface of the body. It helps line the body cavities and organ cavities. There is no extracellular matrix between the cells that are located in the epithelial tissues because they are closely packed. The epithelial is also composed of one or more layers of packed cells. The other major tissue is the connective tissue‚ which is more diverse and abundant‚ compared to the other tissues. The function

he nervous system is the communication network of the body. It consists of a complex collection of nerves and specialized cells‚ called neurons‚ that transmit messages across the different parts of the body in order for it to function and react correctly. They are known as the building blocks of the nervous system. Structurally they have long extensions that extend out from the cell body. There are two types of these extensions; dendrites‚ which are extensions of the neurons that receive signals
