a.

To control internal organs

b.

To protect the brain and spinal cord

c.

To produce cerebro-spinal fluid

d.

None of the above

Discuss

Q52.
When an individual is frightened, which of the following systems will cause his heartbeat to become faster?

a.

Parasympathetic nervous system

b.

Sympathetic nervous system

c.

Central nervous system

d.

Sensory nervous system

Discuss
Answer: (b).Sympathetic nervous system Explanation:The sympathetic nervous system is involved in the fight or flight response which is triggered when an individual is frightened. When activated, the sympathetic system increases the heart rate, which in turn helps to pump more blood to the body's muscles and organs, preparing them for action. The parasympathetic system, on the other hand, has the opposite effect and slows down heart rate. The central nervous system is not directly involved in controlling the heart rate, but rather it receives sensory input from the peripheral nervous system and sends out motor responses to the body. The sensory nervous system is responsible for transmitting sensory information from the body to the central nervous system and is not directly involved in controlling heart rate.
Q53.
What are vascular disorders?

A diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images of the body

d.

A special needle placed into the lower back to measure the pressure in the spinal canal and brain and remove a small amount of cerebral spinal fluid for testing

Discuss
Answer: (d).A special needle placed into the lower back to measure the pressure in the spinal canal and brain and remove a small amount of cerebral spinal fluid for testing Explanation:A Spinal Tap or lumbar puncture is a special needle placed into the lower back, into the spinal canal.
