Q121.
Which part of the brain is responsible for relaying information between body muscles and areas of the cerebral cortex that are involved in motor control?

a.

Cerebellum

b.

Thalamus

c.

Hypothalamus

d.

Brain stem

Discuss
Answer: (a).Cerebellum Explanation:The cerebellum is located at the back of the brain, between the cerebrum and the brain stem, and is responsible for receiving and relaying information between body muscles and areas of the cerebral cortex that are involved in motor control.
Q122.
What is the function of the hypothalamus?

a.

To control the involuntary actions of internal organs

b.

To connect areas of the cerebral cortex involved in sensory perception and movement

c.

To serve as the reflex center for all spinal reflexes

d.

To control autonomic functions performed by the peripheral nervous system

Discuss
Answer: (d).To control autonomic functions performed by the peripheral nervous system Explanation:The hypothalamus is the controlling unit of many of the autonomic functions performed by the peripheral nervous system, such as regulating body temperature, hunger and thirst, and the sleep-wake cycle.
Q123.
Which part of the nervous system controls the involuntary actions of internal organs, blood vessels, and smooth and cardiac muscles?

a.

Peripheral nervous system

b.

Central nervous system

c.

Autonomic nervous system

d.

Somatic nervous system

Discuss
Answer: (c).Autonomic nervous system Explanation:The autonomic nervous system is also known as the involuntary nervous system and consists of motor neurons that control the involuntary actions of internal organs, blood vessels, and smooth and cardiac muscles.
Q124.
Which part of the nervous system facilitates conscious reactions to environmental changes?

a.

Autonomic nervous system

b.

Central nervous system

c.

Somatic nervous system

d.

Peripheral nervous system

Discuss
Answer: (c).Somatic nervous system Explanation:The somatic nervous system is also known as the voluntary nervous system and facilitates conscious reactions to environmental changes, such as movement and sensation.
Q125.
What are the two major functions of the spinal cord?

a.

Controlling involuntary actions and regulating body temperature

b.

Receiving and relaying information between body muscles and the cerebral cortex

c.

Providing two-way conduction routes to and from the brain and serving as the reflex center for all spinal reflexes

d.

Connecting areas of the cerebral cortex involved in sensory perception and movement with other parts of the brain and spinal cord

Discuss
Answer: (c).Providing two-way conduction routes to and from the brain and serving as the reflex center for all spinal reflexes Explanation:The spinal cord is a cylindrical shaped extension of the brain that is surrounded by vertebral bodies that form the spinal column. The two major functions of the spinal cord are to provide two-way conduction routes to and from the brain and to serve as the reflex center for all spinal reflexes.
Q126.
What is the function of the thalamus?

a.

To control the involuntary actions of internal organs

b.

To connect areas of the cerebral cortex involved in sensory perception and movement with other parts of the brain and spinal cord

c.

To receive/relay information between body muscles and areas of cerebral cortex involved in motor control

d.

To control voluntary actions, speech, senses, thoughts, and memories.

Discuss
Answer: (b).To connect areas of the cerebral cortex involved in sensory perception and movement with other parts of the brain and spinal cord Explanation:The thalamus is located in the lower central part of the brain and its main function is to connect those areas of the cerebral cortex that are involved in sensory perception and movement with those parts of the brain and spinal cord that also have a role in sensory perception and movement. It relays information between these different parts of the nervous system to facilitate communication and coordinated responses to stimuli.
