Unconscious and Conscious Responses

Question 1

What is a conscious response

Answer 1

voluntary reaction to sensory stimuli that means the person is aware of their action

Question 2

What is an unconscious response

Answer 2

automatic and involuntary response to stimuli

Question 3

Answer 3

somatic ns

Question 4

Question 5

A spinal reflex is

Answer 5

an automatic and involuntary response that occurs to stimuli and doesn’t involve the brain

Question 6

What is an example of a spinal reflex

Answer 6

pulling away from a hot or sharp object

Question 7

What is the process of the spinal reflex when you touch something hot?

Answer 7

• pain is received by sensory neurons
• travels to the spinal cord by a sensory neural pathway
• message is received by an interneuron in the spinal cord
• message is sent by spinal cord via motor neurons to withdraw the hands

Question 8

What is a reflex arc?

Answer 8

is a neural pathway that controls a reflex and doesn’t involve the brain

Question 9

What are the two types of reflex arcs?

Answer 9

Monosynaptic and polysynaptic

Question 10

What is a monosynaptic reflex

Answer 10

involves only one synapse

- affector neuron brings message to synapse and effector neuron transfer it to the muscle

Question 11

What is a polysynaptic reflex

Answer 11

• involves an interneuron that connects the affector and effector neurons
• at least 2 synapses

Question 12

What is the difference between a polysynaptic reflex and a monosynaptic reflex

Answer 12

• monosynaptic = one synpase

- polysynaptic = at least 2 synapses
