Primary Motor Cortex
|
Located in the frontal lobe, contains motor neurons that send axons to specific skeletal muscles
|
|
Premotor Area
|
Controls the organization of movements before they are initiated and rhythmic coordination between movements
|
|
Supplementary Motor Area
|
control of sequential movements, preparation and organization of movements
|
|
Parietal Love
|
voluntary movement, integration of movement preparation and execution processes by interacting with the premotor, primary, and supplementary motor cortexes
|
|
Basal Ganglia
|
Nuclei buried within cerebral hemispheres, planning and initiation of movement and control of antagonist muscles
|
|
parkinson's Disease
|
Basal ganglia disorder, don't produce enough of NT dopamine, bradykinesia, tremors, muscle rigidity
|
|
Diencephalon
|
thalamus=relay station, attention, mood, perception of pain. Hypothalamus=control of endocrine, homeostasis, response to stress
|
|
Cerebellum
|
execution of smooth and accurate movements
|
|
Brainstem
|
pons=chewing, swallowing, balance. medulla=respiration, heartbeat, crossing site. Reticular formation=chain of nuclei, lie between sensory receptors and motor control centers, integrator of sensory and neural impulses
|
|
Limbic System
|
Learning of motor skills
|
|
Ascending Tracts
|
transmission of sensory info, important to control of voluntary movement, proprioception, touch, pressure, pain, temperature
|
|
Motor Unit
|
Neuron and all the muscle fibers it innervates, fine movements have small motor units
|
|
Motor Unit Recruitment
|
Increasing the number of motor units in order to increase the number of muscle fibers active at any one time, thereby increasing the force the muscle can exert
