Comparison of Skeletal Muscle to Other Muscle Types--CARDIAC MUSCLE---STRIATED INVOLUNTARY--(matching with skeletal muscle) Flashcards
1
Q
General Characteristics of Muscle Fibers
A
Appearance
Nuclei
2
Q
Appearance
A
-Intermediate length, thin, branched
3
Q
Nuclei
A
-One per cell
4
Q
Specialization
A
Branched and connected via intercalated discs
5
Q
What do Intercalated discs do?
A
allow the action potential to pass directly from one
fiber to another so that groups of fibers are stimulated simultaneously
and therefore contract together or in unison.
6
Q
What is the Action
A
-Does not require stimulation from the nervous system.
Instead, pacemaker cells stimulate contraction.
7
Q
Control-
A
-Unconscious/Involuntary
8
Q
What type of smooth muscle also uses pacemaker cells?
A
Visceral/Unitary
