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) Golgi tendon organ
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
