Answer |
| Epithelial tissue covers and lines? |
Covers and lines all spaces (cavities)NOT Joints.--Cells are closely packed together with very little extracelluar fluid. |
| Epithelial tissue cells are attatched to? |
Underlying Connective Tissue.via basement membrane. --Avascular?= No Blood vessels. |
| Epithelial Tissue has? |
Good nerve supply and a high mitotic rate.- Some form glands and lines ducts. |
| Exocrine and Indocrine Glands are made up of? |
Epithelial Tissue. |
| General Structure of Epitelial Tissue |
1.Apical Surface- Lines the space---2.Epithelial cells may be single or multiple layers---3.Basement Membranes hold the Epithelial cells to the underlying Connective Tissue. |
| Basemnet membrane is made up of two Layers? |
Basal Lamina and below Reticular Lamina. |
| General types of Epithelium ---Covering and lining Epithelium ? |
-Epidermis of skin-Lining of blood vessels and ducts (glands)Lining of respirtory, reproductive, Urinary and GI tract. |
| General types of Epithelium ---Glandular Epithelium ? |
-Cells secrete a product-Ex. Thyroid, Adrenal, and Sweat Glands. |
| Papanicolaou Smear (Pap smear) |
Collect sloughed off cells of uterus and the vaginal walls.Cells stained and studied by Pathologist.detect cellular changes (Pre-Cancerous cellsAnnually for women over 18 or if sexually active. |
| Glandular Epithelium-Glands are derived from Epithelial cells that develop below the surface during development.Two types? #1? |
Exocrine Glands-cells secrete a product into a Duct or into a body cavity or to the outside of the skin.Ex Sweat, Saliva, Digestive Enzymes.exist as unicellular glands or Multicellular Glands. |
| Glandular Epithelium-Glands are derived from Epithelial cells that develop below the surface during development.Two types? #2? |
Endocrine Glands- Cells secrete hormones.Hormones are chemicals that are secreted into the blood stream and affect the growth and metabolic activity of "Target Cells" to maintain Homeostasis.Ex. Pituitary Gland, Ovaries and Testes |
