PQ 6.5 REFLEXES, PROPRIOCEPTION, AND MOVEMENT

What are reflexes?

• Voluntary and conscious responses to stimuli

• Automatic and rapid responses to stimuli

• Slow and deliberate responses to stimuli

• Responses that involve the activation of smooth muscle, cardiac muscle, and glands

Where is the command centre for cerebral reflexes located?

• In the brain

• In the spinal cord

• In the autonomic division of the nervous system

• In the somatic division of the nervous system

Which division of the nervous system mediates autonomic reflexes?

• Somatic division

• Motor division

• Sympathetic division

• Autonomic division

What bodily functions do autonomic reflexes regulate?

• Digestion, elimination, blood pressure, salivation, and sweating

• Muscle contraction, joint movement, and body posture

• Vision, hearing, taste, and smell

• Memory, learning, and decision-making

Which division of the nervous system is involved in somatic reflexes?

• Autonomic division

• Motor division

• Sympathetic division

• Somatic division

What is the purpose of somatic reflexes?

• To regulate bodily functions

• To control smooth muscle, cardiac muscle, and glands

• To respond to unexpected stimuli

• To transmit information between neurons

What are the three types of neurons in the human body?

• Sensory neurons, motor neurons, and interneurons

• Autonomic neurons, somatic neurons, and reflex neurons

• Sympathetic neurons, parasympathetic neurons, and central neurons

• Cerebral neurons, spinal neurons, and peripheral neurons

What is the function of sensory neurons?

• To detect or sense information from the outside world

• To send signals away from the CNS

• To form interconnections between other neurons in the CNS

• To regulate bodily functions

What is the function of motor neurons?

• To detect or sense information from the outside world

• To send signals away from the CNS

• To form interconnections between other neurons in the CNS

• To regulate bodily functions

What is the function of interneurons?

• To detect or sense information from the outside world

• To send signals away from the CNS

• To form interconnections between other neurons in the CNS

• To regulate bodily functions
