Seriomotor control

Question 1

What is a reflex?

Answer 1

simplest motor behaviour
least affected by voluntary control
rapid, stereotyped, involuntary responses
controlled by stimulus
sensory processing occurs in spinal cord

Question 2

What are rhythmic motor patterns?

Answer 2

walking, running, chewing
initiation and termination are voluntary
once initiated continues automatically
sensory processing occurs sub cortically

Question 3

What is voluntary movement?

Answer 3

most complex
purposeful 
mainly learned
the more practice, less conscious direction is needed
sensory processing occurs in cortex

Question 4

What is the sensorimotor control?

Answer 4

produces movement

sensation is important

Question 5

What types of information does the somatosensory system carry?

Answer 5

exteroceptive information
proprioceptive information
interoceptive information

Question 6

What is a dorsal column pathway?

Answer 6

back of the spinal cord
carries tactile sensation
proprioception

Question 7

What is the spinothalamic pathway?

Answer 7

lateral part of the spinal cord
pain
crude tactile sensation
goes into the thalamus

Question 8

What is the motor system?

Answer 8

all input directly or indirectly via internuerons to the alpha motor neurons
alpha motoneuron goes directly to the muscle and is influenced by sensory system, cerebrel cortex, brainstem and spinal cord
