Portage Learning Anatomy and Physiology 2 Module 1
Examination (A&P) Exam Questions and Answers
What is the difference between anatomy and physiology? - ANSWER>>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.
The function of the nervous system is to integrate and control the other body
systems. Explain how the nervous system does this. - ANSWER>>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.
List the 2 parts of the nervous system. - ANSWER>>CNS and PNS (central nervous
system and peripheral nervous system)
How are the parts of the central nervous system protected? - ANSWER>>The skull
protects the brain and the vertebrae protect the spinal cord.
Collections of cell bodies inside the central nervous system are called _____, and
the collection of nerve axons in the central nervous system are called _____ -
ANSWER>>nuclei, tracts
What is included in the peripheral nervous system? - ANSWER>>The PNS includes
the cranial nerves and the spinal nerves
Collections of cell bodies inside the peripheral nervous system are called _____,
and the collection of nerve axons in the peripheral nervous system are called
_____ - ANSWER>>ganglia, nerves
, What are the 2 divisions of the peripheral nervous system? - ANSWER>>Afferent,
efferent
Describe the movement of nerve impulses in the peripheral nervous system. -
ANSWER>>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
What are the 2 divisions of the efferent division of the peripheral nervous
system? - ANSWER>>Somatic system and the autonomic system
What is controlled by the somatic and autonomic nervous systems? -
ANSWER>>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
What are the 2 divisions of the autonomic nervous system? -
ANSWER>>sympathetic and parasympathetic nervous systems
What is the function of the sympathetic nervous system? - ANSWER>>The
sympathetic nervous system activates and prepares the body for vigorous
muscular activity, stress, and emergencies
What is the function of the parasympathetic nervous system? - ANSWER>>The
parasympathetic nervous system generally operates during normal situations,
permits digestion, and conserves energy
List 3 unusual characteristics of neurons - ANSWER>>Neurons do not undergo
mitosis (cell division), require enormous amounts of fuel being able to survive just
minutes without oxygen and can last an entire human lifetime.
