Tissues Flashcards
1
Q
Epithelial tissue
A
- covers body surfaces
- lines hollow organs, body cavities, and ducts
2
Q
Connective
A
- provides protection and structural support
3
Q
Muscular
A
- composed of specialized cells that can contract and generate force
- produces body movements (locomotion, propulsion)
- maintains posture and generates heat
4
Q
Nervous
A
- generates electrical signals in response to external and internal stimuli
- allows for quick communication between distant body structures
- contributes to maintaining homeostasis
5
Q
Functions of the integumentary system
A
- regulate body temperature
- store blood
- protect body from external environment
- detect cutaneous sensations
- excrete and absorb substances
- synthesize vitamin D
6
Q
Levels of epidermis
A
- corneum
- lucidum
- granulosum
- spinosum
- basale
7
Q
Arrangement of epithelial tissue
A
- arrangement of layers = simple, stratified, pseudostratified
- cell shape = squamous, cuboidal, columnar
8
Q
Classes of connective tissue
A
- loose (adipose) = adipocytes
- dense (tendon) = fibroblasts
- cartilage (hyaline) = chondrocyte
- bone (osteon) = osteocytes, osteoblasts
- blood = erythrocytes
9
Q
Smooth muscle
A
- fusiform/spindle
- one centrally located nucleus
- involuntary (ANS)
10
Q
Cardiac muscle
A
- cylindrical and branched
- stratiations
- one/two central nuclei
- involuntary (ANS)
11
Q
Skeletal
A
- large rod shaped
- striations
- many peripheral nuclei
- voluntary (somatic nervous system)
