Define Histology
|
the science dealing with the microscopic identification of cells and tissue.
|
|
Name the four types of tissue
|
1. Epithelial
2. Connective 3. Nervous 4. Muscle |
|
Characteristics of Epithelial tissue
|
Closely packed flat cells
Avascular Exposed to outside (body surface) Cell division occurs readily has nerve supply |
|
Two types of epithelial tissue
|
Covering and lining epithelium
Glandular epithelium |
|
Epithelial cell shape
|
Squamous
Cuboidal Columnar Transitional |
|
Describe squamous and give example
|
Flat, nucleus located near the upper surface, gives these cells the appearance of a fried egg.
Ex. Skin |
|
Decribe Cuboidal
|
Are cube or hexagon shaped with a central, circular nucleus.
Ex. digestion |
|
Describe Columnar
|
Are tall with an oval nucleus near the basement membrane. May have microvilli, or cilia.
Ex.respiratory tract |
|
Describe Transitional
|
Range from flat to tall that can extend or compress in response to body movement. Ex. Bladder
|
|
Give the names of the cell layers (generic)
|
1. Simple (single)
2. Stratified (multiple) 3. Pseudostatified describes single layer cells of different sizes. (appearance of multilayered) |
|
Name the two types of glandular epithelium
|
1. Endocrine
2. Exocrine |
|
Endocrine secrete _________ directly into the ___________
|
hormones & bloodstream
|
|

|
tube, ducts, epithelial
|
|
Give examples of exocrine secretions:
|
Sweat
