functions of the muscular system (3)
A
- movement
- heat (thermogenesis)
- posture
2
Q
types of muscle (3)
A
- cardiac muscle
- smooth muscle
- skeletal muscle tissue
3
Q
smooth muscle (3)
A
(muscle of organs)
- involuntary control
- non-striated
- mono-nucleate
- visceral smooth muscle most common (peristalsis)
4

6
Q
Structure of skeletal muscle mass (3)
A
sarcomere
7

sarcolemma
A
transmits contractions from motor neurons
8

A
distributes calcium
9
Q
muscle anatomy: origin
A
remains stationery (door hinge)
10
Q
muscle anatomy: insertion
A
movable part of muscle (door)
11
Q
muscle anatomy: muscle belly
A
portion between origin/insertion
12
Q
aponeurosis:
A
broad, thin, flat sheets, dense connective tissue
13
Q
perimysium
A
separates muscle mass into small bundles of muscle fibers
14
Q
bursa (2)
A
- fluid filled sacks associated with joints
- reduce friction
15
Q
neuromuscular junction (2)
A
- region of communication between a motor neuron/muscle fiber
- not physical connection
