Question 1
Anatomy and Physiology of the Nervous System: Introduction
Answer the following:
• What is the difference between anatomy and physiology?
Anatomy focuses on the structure of the body. Physiology looks at how the body parts
function together. The physiology of the body depends on the anatomy of the body.
Rationale: Correct distinction.
• The function of the nervous system is to integrate and control the other body
systems. Explain how the nervous system does this.
The nervous system receives and processes information and sends out signals to the
muscles and glands to elicit an appropriate response. In this way, the nervous system
integrates and controls the other systems of the body.
Rationale: Correct explanation.
• List the 2 parts of the nervous system.
CNS and PNS (central nervous system and peripheral nervous system)
Rationale: Correct.
• How are the parts of the central nervous system protected?
The skull protects the brain and the vertebrae protect the spinal cord.
Rationale: Correct.
• Collections of cell bodies inside the central nervous system are called , and the
collection of nerve axons in the central nervous system are called .
nuclei, tracts
Rationale: Correct terminology.
• What is included in the peripheral nervous system?
The PNS includes the cranial nerves and the spinal nerves.
Rationale: Correct.
• Collections of cell bodies inside the peripheral nervous system are called , and
the collection of nerve axons in the peripheral nervous system are called .
, ganglia, nerves
Rationale: Correct.
• What are the 2 divisions of the peripheral nervous system?
Afferent, efferent
Rationale: Correct.
• Describe the movement of nerve impulses in the peripheral nervous system.
The peripheral nervous system receives impulses from the sensory organs via the
afferent division and then relays signals or impulses from the central nervous system to
muscles and glands via the motor or efferent division.
Rationale: Correct description.
• What are the 2 divisions of the efferent division of the peripheral nervous
system?
Somatic system and the autonomic system.
Rationale: Correct.
• What is controlled by the somatic and autonomic nervous systems?
The somatic system controls the movements of skeletal muscles, skin, and joints. The
autonomic system nerves control the glands and smooth muscles of the internal
organs.
Rationale: Correct.
• What are the 2 divisions of the autonomic nervous system?
sympathetic and parasympathetic nervous systems
Rationale: Correct.
• What is the function of the sympathetic nervous system?
The sympathetic nervous system activates and prepares the body for vigorous
muscular activity, stress, and emergencies.
Rationale: Correct.
• What is the function of the parasympathetic nervous system?
The parasympathetic nervous system generally operates during normal situations,
permits digestion, and conserves energy.
Rationale: Correct.
