involuntary nonstriated muscle
5
Q
characteristics of all muscle tissues
A
- specialized cells
- excitability/ irritability
- contractility
- extensibility
- elasticity
6
Q
specialized cells
A
elongated high density of myofilaments= cytoplasmic filaments of actin and myosin
7
Q
excitability/irritability
A
receive and respond to stimulus
8
Q
contractility
A
shorten and produce force upon stimulation
9
Q
extensibility
A
can be stretched
10
Q
elasticity
A
recoil after stretch
11
Q
skeletal muscle tissue
A
-forms skeletal muscles (44% of body mass)
12
Q
skeletal muscle
A
an organ: composed of skeletal muscle cells (fibers) CT nerves and blood vessels
13
Q
Functions of skeletal muscles:
A
- produce skeletal movement
- maintain posture and upright position
- stabilize joints
- support soft tissues
- guard entrances and exits
- generate heat (maintain body temp)
