Muscle Movement
Requiring the use of oxygen during movements (like a debit card); happens with slow-twitch fibers
Aerobic
Muscles that control the digestive system and other organs
Smooth muscles
A type of movement that proceeds as a single organized unit that cannot be redirected once it begins
Ballistic movement
This large subcortical structure is part of the basal ganglia and inhibits the thalamus.
globus pallidus
In Parkinson's disease, which pathway in the brain degenerates?
Substantia nigra to caudate nucleus and putamen
Muscle fibers that produce fast contractions but fatigue rapidly
Fast-twitch fibers
Muscles that control movement of the body in relation to the environment.
Skeletal (striated) muscles
A type of movement that involves an automatic and consistent muscular responses to stimuli
Reflexes
Receptors that respond to increases in muscle tension; inhibit further contractions
Golgi tendon organ
Too much movement that includes jerks and twitches, facial movements, writhing, and unsteady gait are symptoms of which disease?
Huntington's disease
This receptor is sensitive to the position and movement of a part of the body.
Proprioceptor
Muscles of the heart that have properties intermediate between those of smooth and skeletal muscles
Cardiac muscles
A reflexive contraction of a muscle in response to a stretch of that muscle
Stretch reflex
A large subcortical structure that is part of the basal ganglia; inhibits globus pallidus with caudate
Putamen
This disease is caused by damage to the basal ganglia, which causes the globus pallidus to stop inhibiting movement. It is very high genetically.
Huntington's Disease?
A receptor parallel to the muscle that responds to a stretch
Muscle spindle
Opposing sets of muscles that are required to move a leg or arm back and forth
Antagonistic muscles
A type of movement that involves a fixed sequence of movements; e.g. locomotion, wet dog shake, wing flapping, chewing in lobsters
-more complex than reflexes
Motor program
The structure composted of the composed of the caudate nucleus, putamen, and globus pallidus, lateral to the thalamus, that select a movement by stopping inhibition of it
basal ganglia
Damage to this area is most likely to interfere with rapid movements that require timing.
Cerebellum
A synapse between a motor neuron axon and a muscle fiber
Neuromuscular junction
Fast-twitch and slow-twitch fibers are examples of these muscles as they look at the movement of the body in relation to the environment.
Skeletal muscles/striated muscles
A chameleon tongue extending is an example of this movement.
Ballistic Movement
Large subcortical structure, part of the basal ganglia, inhibits globus pallidus with putamen
Caudate nucleus
Deep Brain Stimulation or L-Dopa are treatments for this disease.
