-
Aerobic process
one that uses oxygen during the activity
-
Anaerobic process
process that does not require oxygen at the time
-
Central pattern generator
neural mechanism in the spinal cord or elsewhere that generates rhythmic patterns of motor output
-
Motion that proceeds as a single organized unit that cannot be redirected once it begins
Ballistic movement
-
 Corticospinal Tracts
axon paths from the cerebral cortex to the spinal cord
-
Extensor
Muscle that extends a limb FROM the body
-
What is the name of the muscle fibers that produce fast contractions but fatigue rapidly, and do they need oxygen?
If they need oxygen, what is that called - if they don't need oxygen, what is that called?
- Fast-Twitching fibers
- Does not need oxygen, however - need plenty of oxygen to refill afterwards
- No need for oxygen during activity: Anaerobic process
-
Muscle that flexes a limb against the body
Flexor
-
 Receptor that responds to the contraction of a muscle, also known as Spindle organ
A) Globus pallidus
B) Lateral corticospinal tract
C) Golgi tendon organ
C) Golgi tendon organ (this multiple choice question has been scrambled)
-
Fixed sequence of Movements that occur as a single unit (hint: tv-show/cars)
Motor program!
-
MPTP, MPP are chemicals known to be toxic to the dopamine-containing cells in the substantia nigra, capable of producing the symptoms of which disease?
Parkinsons
-
 Receptor parallel to the muscle that responds to the stretch of a muscle
Muscle Spindle
-
Myasthenia gravis (autoimmunal disease) attachs which N.T. receptors at which junctions (sensory/motor)
Disease in which the immune system attacks the acetylcholine receptors at the nerve-muscle junctions
-
Neuromuscular junction
Synapse where a motor neuron's axon meets a muscle fiber
-
Nuclei of the cerebellum sends axons to which type of areas?
Clusters of neurons in the interior of the cerebellum that send axons to motor-controlling areas outside the cerebellum
-
Malady caused by damage to a dopamine pathway, resulting in slow movements, diffi culty initiating movements, rigidity of the muscles, and tremors
Parkinson's disease
-
Just anterior to the primary motor cortex, is an area called Premotor cortex - what is the main function regarding movement of this area?
Planning of a movement
-
Consistent, automatic response to a stimulus (come on, you know this!)
Reflex
-
What Type of Muscles control the movement of the body in relation to the environment (e.g., arm and leg muscles)
Skeletal (striated) muscles
-
Striated Muscles aka?
- Skeletal muscles
- muscles that control the movement of the body in relation to the environment (e.g., arm and leg muscles)
-
Muscles that control the movements of internal organs
Smooth muscles...
