Voluntary movement

Question 1

Explain the first step of voluntary movement

Answer 1

Sensory stimuli is detected by sensory receptors (E.g, a hand comes into contact with cold water, or the retina detects a stimuli such as a remote the person wants to use)

Question 2

Explain the second step of voluntary movement

Answer 2

An Afferent neural impulse is transmitted via afferent pathways in the SNS to the spinal cord & then the brain (E.g the cold sensation is sent to the brain or presence of the remote is sent to the brain)

Question 3

Explain the third step of voluntary movement

Answer 3

The brain then processes the sensory information and coordinates & initiates a conscious motor response

Question 4

Explain the fourth step of voluntary movement

Answer 4

The Motor/Efferent neural impulse is transmitted via efferent pathways in the spinal cord, then to the SNS located in the PNS & to the skeletal muscles

Question 5

Explain the fifth step of voluntary movement

Answer 5

The skeletal muscles then carry out the conscious motor response to the sensory stimuli

Question 6

What are key terms you should use in a question regarding voluntary movement?

Answer 6

• Sensory receptors & stimuli
• Sensory/afferent neurons
• Brain, CNS, spinal cord
• Motor/efferent neurons, PNS
• Skeletal muscles
• SNS & Voluntary response
