Nervous System - Motor Control & Somatic Sensation

Question 1

stretch reflex function

Answer 1

prevents muscle overstretch

Question 2

withdrawal reflex function

Answer 2

pulls body part away from painful stimulus

Question 3

stretch reflex process

Answer 3

when muscle spindle senses stretch:

sensory neuron sends signal to spinal cord then synapses directly with motor neuron, motor neuron causes muscle contraction. (monosynaptic)

Question 4

withdrawal reflex process

Answer 4

pain receptor (skin):

sensory neuron sends signal to spinal cord that connect with interneurons, interneurons activate motor neurons that pull limb away.

Question 5

muscle tension

Answer 5

golgi tendon organs
when tension is too high they inhibit contraction

Question 6

voluntary movement

Answer 6

motor cortex
signals go down corticospinal tract to spinal cord motor neurons and muscles contract

Question 7

sensory receptors

Answer 7

detect stimuli

Question 8

modality

Answer 8

type of stimulus

Question 9

location

Answer 9

which receptor is activated

Question 10

intensity

Answer 10

frequency of APs

Question 11

duration

Answer 11

how long stimulus lasts

Question 12

basal ganglia

Answer 12

initiates patterns of movement
