- 1.
The function of the central nervous system includes: (Select three)
- A.
Is the seat of all sensation
- B.
Controls all movement of involuntary muscle
- C.
Is the seat of all special senses
- D.
Is the seat of higher mental powers – reasoning and so on
- E.
Controls non vital functions
Correct Answer(s)
A. Is the seat of all sensation
C. Is the seat of all special senses
D. Is the seat of higher mental powers – reasoning and so onExplanation
The central nervous system is responsible for processing and interpreting sensory information, which includes all sensations. It also plays a role in the functioning of special senses such as vision, hearing, taste, and smell. Additionally, the central nervous system is involved in higher mental processes such as reasoning, problem-solving, and decision-making.Rate this question:

Reflexes are fast responses to the internal or external changes in the environment.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Reflexes are automatic and rapid responses to stimuli, whether they are internal or external. They are not under conscious control and occur in order to protect the body from potential harm or danger. Examples of reflexes include blinking when a bright light is suddenly shone in the eyes or pulling the hand away from a hot surface. Therefore, the statement that reflexes are fast responses to changes in the environment is true.Rate this question:

The sensory stimulus is carried into the spinal cord by motor fibres.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is incorrect. Sensory stimulus is carried into the spinal cord by sensory fibers, not motor fibers. Motor fibers, on the other hand, carry signals from the brain to the muscles and glands to initiate movement or other responses.Rate this question:

The ______ nervous system supplies nerves to all the internal organs of the body and blood vessels.
- A.
Parasympathetic
- B.
Sympathetic
- C.
Autonomic
Correct Answer
C. AutonomicExplanation
The autonomic nervous system is responsible for regulating the internal organs and blood vessels of the body. It controls involuntary functions such as heart rate, digestion, and breathing. Both the parasympathetic and sympathetic divisions are part of the autonomic nervous system, but they have different functions. The parasympathetic division is responsible for rest and digestion, while the sympathetic division is responsible for the fight or flight response. Therefore, the correct answer is autonomic.Rate this question:

Behind the heart in the thoracic region is the solar plexus.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because the solar plexus is actually located in front of the heart in the thoracic region. The solar plexus is a complex network of nerves located in the abdomen, behind the stomach and in front of the aorta. It is responsible for regulating various bodily functions such as digestion and heart rate.Rate this question:

The autonomic nervous system controls and regulates the activities of smooth muscles, cardiac muscles and certain glands.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The autonomic nervous system is responsible for controlling and regulating involuntary bodily functions such as the contraction of smooth muscles, cardiac muscles, and the secretion of certain glands. These functions include the beating of the heart, digestion, breathing, and the release of hormones. Therefore, it is true that the autonomic nervous system controls and regulates the activities of these muscles and glands.Rate this question:

Reflex action occurs as a result of the stimulation of the motor cells by stimuli transmitted by afferent neurones from the tissues.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Reflex action occurs when motor cells are stimulated by stimuli transmitted by afferent neurons from the tissues. This means that when a stimulus is detected by sensory neurons, it is quickly and automatically processed by the nervous system, resulting in an immediate and involuntary response. This is a fundamental mechanism that helps protect the body and maintain homeostasis. Therefore, the statement is true.Rate this question:
