Chapter 4 Neuromotor Basis For Control

Front 1

Primary Motor Cortex

Back 1

Located in the frontal lobe, contains motor neurons that send axons to specific skeletal muscles

Front 2

Premotor Area

Back 2

Controls the organization of movements before they are initiated and rhythmic coordination between movements

Front 3

Supplementary Motor Area

Back 3

control of sequential movements, preparation and organization of movements

Front 4

Parietal Love

Back 4

voluntary movement, integration of movement preparation and execution processes by interacting with the premotor, primary, and supplementary motor cortexes

Front 5

Basal Ganglia

Back 5

Nuclei buried within cerebral hemispheres, planning and initiation of movement and control of antagonist muscles

Front 6

parkinson's Disease

Back 6

Basal ganglia disorder, don't produce enough of NT dopamine, bradykinesia, tremors, muscle rigidity

Front 7

Diencephalon

Back 7

thalamus=relay station, attention, mood, perception of pain. Hypothalamus=control of endocrine, homeostasis, response to stress

Front 8

Cerebellum

Back 8

execution of smooth and accurate movements

Front 9

Brainstem

Back 9

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

Front 10

Limbic System

Back 10

Learning of motor skills

Front 11

Ascending Tracts

Back 11

transmission of sensory info, important to control of voluntary movement, proprioception, touch, pressure, pain, temperature

Front 12

Motor Unit

Back 12

Neuron and all the muscle fibers it innervates, fine movements have small motor units

Front 13

Motor Unit Recruitment

Back 13

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
