Displaying results 1 to 10.

1. Basal lamina
A thin layer of noncellular protein s and other noncellular stuff that is underneath the epithelium (the top layer of skin cells, also the innermost layer of cells in various vessels, the digestive and other tracts, etc.) and that the epithelium makes.

2. Cilium (pl. cilia)
Microtubular , hairlike structures that some single-celled organisms use for locomotion through liquids. They also cover the cells of certain tissues, such as the epithelium lining the lungs, and help those cells sweep away fluids or particles. Cilia are smaller than flagella .

3. Epithelial tissue
Cells in animals that are closely packed in either single or multiple layers, and which cover both internal and external surfaces of the animal body. Also referred to as epithelium.

4. Epithelium (epithelial)
The covering of an organism or an organ. The layer(s) of cell s between the organism or its tissues or organs and the environment. Examples include the skin cells, the inner linings of the lungs and the digestive tract, etc.

5. Fibrocystic disease of the breast (mammary dysplasia)
Mammary dysplasia includes fibrosis of the breast tissue which gives the breast a rubbery consistency. Cyst formation is another feature. Hyperplastic epithelium , another feature of this condition, has been thought to have potential to progress to breast cancer.

6. Hemorrhoids
Hemorrhoids are dilated veins in the anus. Internal hemorrhoids: dilated veins of the plexuses of the superior and middle hemorrhoidal veins above the mucocutaneous junction. Internal hemorrhoids drain to the portal vein. External hemorrhoids: dilated veins of the inferior hemorrhoidal plexus below the mucocutaneious junciton the the tissues beneath the anal epithelium of the anal canal. External hemorrhoids drain into the systemic circulation. These veins become symptomatic when the venous pressures increase: such as in constipation, straining to defecate, pregnancy, tumors, and portal hypertension .

7. Juxtaglomerular apparatus
The juxtaglomerular apparatus is form by cells near the glomerulus of the kidney, consisting of: * juxtaglomerular cells (JG cells), epithelioid cells in the media of the afferent arterioles as they enter the glomerulus * macula densa: tubular epithelium at the region of afferent arteriole and efferent arteriole to the glomerulus The JG cells secrete renin , a process mediated by angiotensin II and vasopressin .

8. Pituitary gland
A small gland located at the base of the brain; consists of an anterior and a posterior lobe and produces numerous hormones . The master gland of the endocrine system , the pituitary releases hormones that have specific targets as well as those that stimulate other glands to secrete hormones. Part of the pituitary is nerve tissue, the rest is glandular epithelium .

9. Pleura
A thin sheet of epithelium that covers the inside of the thoracic cavity and the outer surface of the lungs.

10. Pterygium (pl. pterygia)
This is characterized by atrophy and hyperkeratosis of the epithelium of the conjunctiva of the eye which is caused by repeated exposure to wind and dust. Clinically it is seen as a winglike growth on the nasal half of the conjunctiva, sclera , and cornea .
