Portage Learning Anatomy and Physiology 2 Nervous System
Examination (A&P 2 NS) Exam Questions and Answers
Anatomy and Physiology - ANSWER>>the study of how the body works
Anatomy - ANSWER>>The study of body structure
Physiology - ANSWER>>The study of body function
Does Physiology depend on anatomy? - ANSWER>>Yes, Physiology depends on
the anatomy of the body - depends on the structure of the bones which are hard
surfaces that protect organs from damage
nervous system - ANSWER>>the body's speedy, electrochemical communication
network, consisting of all the nerve cells of the peripheral and central nervous
systems
nervous tissue - ANSWER>>made up of neurons; many neurons throughout the
brain, spinal cord, and the nerves; communication between the cells of the body
by forming a system of electrical impulses that communicate rapidly
What are nerves? - ANSWER>>the "wiring" of the body
Two Main Divisions of the nervous system - ANSWER>>central nervous system
and peripheral nervous system
Central Nervous System (CNS) - ANSWER>>consists of the brain and spinal cord; it
is located at the center, or internal core, of the body
,skull - ANSWER>>protects the brain
Vertebrae - ANSWER>>aka vertebral column; protects the spinal cord
How does the CNS and PNS work together? - ANSWER>>CNS depends on the PNS
to provide it with info from organs about external/internal environment.
PNS depends on CNS to process the info and initiate a response that the PNS
carries to the part of the body.
Nuceli (CNS) - ANSWER>>clusters of cell bodies in the CNS
Tracts (CNS) - ANSWER>>bundles of axons in the CNS
peripheral nervous system - ANSWER>>the sensory and motor neurons that
connect the CNS to the rest of the body
What are the brainstem regions? - ANSWER>>midbrain, pons, medulla
Cranial Nerves (PNS) - ANSWER>>project directly from the brain; innervates the
face, neck, head
Spinal Nerves (PNS) - ANSWER>>project from the spinal cord; innervate the rest
of the body including extremities and trunk
Ganglia (PNS) - ANSWER>>clusters of cell bodies in the PNS
Nerves (PNS) - ANSWER>>bundles of axons
T or F: Does PNS connect all of the body parts of the central nervous system? -
ANSWER>>True
What are the two divisions of the peripheral nervous system? -
ANSWER>>Sensory Division (afferent) and Motor Division (efferent)
, SAME - ANSWER>>S-sensory
A-afferent
M-motor
E-efferent
afferent division (sensory) - ANSWER>>carries sensory information from PNS
sensory receptors to CNS
efferent division (motor) - ANSWER>>Also called the "Motor Division". Carries
signals from the CNS to the effector organs, which are the muscles and glands.
autonomic nervous system (PNS) - ANSWER>>responsible for unconscious body
functions such as heartbeat and breathing
-sympathetic system: responds to stressful time + shuts down nonessential
systems during "fight or flight" situation
-parasympathetic system: counterbalances the sympathetic system
What are the two divisions of the autonomic nervous system? -
ANSWER>>parasympathetic system and sympathetic system
Sympathetic Nervous System (SNS) - ANSWER>>The component of the autonomic
nervous system that responds to stressful situations by initiating the fight-or-flight
response.
parasympathetic nervous system - ANSWER>>the division of the autonomic
nervous system that calms the body, conserving its energy
Neurons - ANSWER>>Individual cells in the nervous system that receive,
integrate, and transmit information.
What are the three basic parts of a neuron? - ANSWER>>dendrites, cell body,
axon
