A
Adduction/Abduction
Side Flexion
Inversion/Eversion
3
Q

A
Circumduction Medial (internal) Rotation Lateral (External Rotation) Horizontal Abduction/ Adduction Protraction/retraction Pronation/Supination
4
Q
Tissue Types
A
- Epithelial
- Connective Tissue
- Muscle Tissue
- Nerve Tissue
5
Q
Characteristics of Epithelial Tissue
A
- Cellularity : Lots of cells w/ little space
- Specialized contacts
- Polarity: Apical Surface faces the “free space”; Basal surface rests on basement membrane
- Supported by connective tissue
- Avascular
- Highly innervated
- highly regenerative
6
Q
Epithelium functions
A
- Protection
- Sensory reception
- Secretion/excretion
- Absorption
- Ion Transport
- Filtration
- Slippery surface for movement of organs (closed body cavities like pleural cavity)
7
Q
Epithelial cell surface specializations
A
- Cilia
- Microvilli
- Glycocalyx
8
Q
Cilia
A
- “beat” like a whip, move cells or substances along cell surface
- Many cilia on a cell surface
9
Q
Microvilli
A
- Stiff like spiky hair
- finger-like extensions that contain cytoplasm
- Increase surface area for absorption
- Called a brush border in the digestive system
10
Q
Glycocalyx
A
- glycolipids and glycoproteins on cell surface used for identification and communication.
- On the surface of the cell and is an identifier
11
Q
Classifying epithelium
A
- Number of Layers
- Shape of TOP layer of cells
- Names are two words followed by epithelium
12
Q
Classifying epithelium: Number of Layers
A
- Simple = 1 single layer
2. Stratified = Multiple layers
13
Q
Classifying epithelium: Shape
A
- Squamous - flat (looks like fried egg)
- Cuboidal - cube shaped
- Columnar - column-shaped
14
Q
Simple Squamous Epithelium Characteristics
A
- Single layer of flat cells
- Nuclei bulge out of the cell like a fried egg
