Physiology Flashcards
1
Q
ATP-PC System
A
- high intensity, short duration
- instantaneous, provides energy for up to 15 seconds
- no O2 required
2
Q
Anaerobic Glycolysis
A
- high intensity, short duration
- no O2 required
- forms lactic acid = muscular fatigue
- slower and provides a person with 30-40 seconds of muscle contraction
3
Q
Aerobic Metabolism
A
- low intensity, long duration
- needs O2
- will only provide energy as long as there are nutrients to use
4
Q
Free Nerve Ending
A
- one is sensitive to non-noxious stimuli
- the other is sensitive to noxious stimuli
5
Q
Golgi Ligament Endings
A
tension or stretch on ligaments
6
Q
Golgi-Mazzoni Corpuscles
A
compression of the joint capsule
7
Q
Pacinian Corpuscles
A
high frequency vibration, acceleration, and high velocity changes in joint position
8
Q
Ruffini Endings
A
stretching on joint capsule; amplitude and velocity of joint position
9
Q
Type I Fibers
A
- slow twitch
- aerobic
- low fatiguability
- large blood supply
10
Q
Type II Fibers
A
- fast twitch
- anaerobic
- high fatiguability
- less blood supply
11
Q
Muscle Spindle
A
- send info to nervous system
- controls posture and involuntary movements
12
Q
Golgi Tendon Organ
A
- sensory receptors
- sensitive to tendon
- transmit information about tension or the rate of change of tension within the muscle
