Motor Control - study of neurophysiological factors (neural behavior, environmental)
Motor learning - study of processes involved in acquiring motor skills
Motor development - study of changes in motor development (reflect the interaction of the maturation
and the environment
Factors influencing motor skills - The learner, nature of the skill, environment
Skills - general movement pattern adapted to work for particular activity
Technique - particular type of same skill is performer
Motor program - the pattern of neural activity required to perform the desired movement, outcome is a
coordinated movement of specific muscles
Motor muscle recruitment involves - 1. Selection of correct/ appropriate muscles
2. The coordination and sequence of these muscles
3. Appropriate force application by muscles
4. Inhibition of other muscles
Afferent neurons - brings information from stimulus towards (sensory)
Efferent neurons - motor neurons that bring information away (motor)
Resting membrane potenial - -40--75 in neurons, maintained by sodium potassium pump
, Action potential (9 steps) - 1. more k+ in cell, Na+ out of cell
2. ligand-gated Na+ channels -> Na+ into cells (deporlarizes cell membrane)
3. threshold -> voltage-gated channels Na+ -> Na+ moves
4. Na+ -> into cell, K+ channels slowly openinh
5. Na+ channels close, K+ channels open
6. K+ channels now open
7. K+ channels slowly close
8. K+ closed RMP (restoring)
9. Na+/ K+ restores RMP pump
Propagation - 1. Starts in the trigger zone (axon hillock)
2. Trigger zone summates
3. Subsquentially open/ close Na+/ K+ pump
4. AP has occurred (propagation begins to the next segment)
5. Absolute refractory period occurs, followed by a relative refractory period
6. RP ensure one -way path for A{ down axon
7. AP continues down axon terminal to end of synapse
Synapse - - Connects two neurons, axon to dendrite
- Responsible for passing signals from presynaptic to postsynaptic neurons
Sense organs - structure composed of nervous tissue along with other tissues designed to enhance
response
Sense receptors - structure specialized to detect a stimulus, some simple, others true
Purpose is transduction
Sensory receptors transmit four kinds of info - Modality, location, duration, intensity
