MAMMALIAN BASIC TISSUE CATEGORIES; [5] |
- Epithelial - Connective - Muscle - Nervous
Some specialised tissues do not easily fit into these categories, ie. blood. |
|
|
HISTOLOGY |
The study of the microscopic structure of tissues. |
|
|
EPITHELIAL; [6] |
- Closely packed, little/no intracellular material (space between them) - Non-vascular (no blood flowing through) - Cover internal + external surfaces, line cavities and ducts and form secretory portion of most glands - Usually supported by basement membrane which separates it from underlying connective tissue - 2 categories: glandular epithelia and surface epithelia - Eg. - Skin, lining of lungs, gut, etc, salivary glands etc |

CHARACTERISTICS OF EPITHELIUM layers [3] and shape [4] |
Layers: - Single: simple - Single (looks multi): pseudostratified - Multiple: stratified
Shape: - Squamous: Flat: - Cuboidal: Square: Cuboidal - Columnar: Tall
Combinations fit particular function of tissue |
|
|
SIMPLE SQUAMOUS; [2] |
