Body Tissues Flashcards
1
Q
Tissue Types
A
- epithelial (covering)
- connective (support)
- muscle (movement)
- nervous (control)
2
Q
Epithelial Tissue
A
- covers all free body surfaces
- tissue form together to form sheets
- avascular
- regenerates easily
3
Q
Epithelial Tissue Function
A
- absorption (kidney & digestive lining)
- secretion (glands)
- filtration (kidney)
- protection (from bacteria, sweat, dust)
4
Q
Connective Tissue
A
- most abundant
- vascularisés
- ECM: composed of structureless ground substance and fiber
- types: bone, cartilage, dense connective tissue, loose connective tissue, blood
5
Q
Functions of connective tissue
A
- binding other tissues
- support
- protection
6
Q
Muscle Tissue
A
- for movement
- used to contract and shorten; contains protein to trigger contraction
- types: skeletal, smooth, cardiac
7
Q
Nervous Tissue
A
- types: neurons, neuroglia
- receive and conduct electrochemical impulses
- irritability and conductibility
- insulate, protect, and support neurons
8
Q
Tissue repair
A
- regeneration: replacement of destroyed tissue by the same kind of cells
- fibrosis: repair of dense connective tissue by creating scar tissue
9
Q
Nervous Tissue function
A
- Coordinates and controls many body activities
- stimulates muscle contractions
- creates awareness of the environment
- major role in emotions, reasoning and memory
