Muscle & Respiratory Lab Flashcards
What are the 3 types of Muscle?
-characteristics of each
1) Cardiac (LOOK FOR INTERCALATED DISC)
- Striated
- Central Nucleus
- Short, Narrow cell
2) Skeletal
- striated
- peripheral nucli
- singl large, elongated cell
3) Smooth
- NOT Striated
- Central Nuscle
- Single Short, Elongate fusiform (tapered cell
What Type of tissue?

Skeletal Muscle
- Striated
- Peripheral Nuclei
- Single Large, elongate cell
What type of tissue?

Cardiac Muscle
CONTAINS INTERCALATED DISCS
- striated
- central nucleus
- short narrow cell
What type of tissue?

Smooth Muscle
- NOT STRIATECD
- Central Nucleus
- Single short, elongate, fusiform (tapered) cell
What type of tissue

Skeletal Muscle
- Striated
- Peripheral nuclei
- Single Large, elongate cell

Intercalated Discs
-onlly found in cardiact muscle
What are the 3 components of intercalated discs?
Fascia Adherens
Gap Junctions
Desmosomes
(ONLY need to know fascia adherens and intercalated Disc)
What structure is the arrow pointing to?

Intercalated Disc
-darker appearnce compared to rest of cardiac muscle
