PRINCIPLES OF ANATOMY AND PHYSIOLOGY
14TH EDITION EXAM PACK QUESTIONS WITH
VERIFIED ANSWERS GRADED A+
◉ Peripheral Nervous System (PNS). Answer: the sensory and motor
neurons that connect the CNS to the rest of the body
◉ nerve. Answer: a bundle of hundreds to thousands of axons plus
associated connective tissue and blood vessels that lies outside the brain
and spinal cord
◉ cranial nerves. Answer: 12 pairs of nerves that carry messages to and
from the brain
◉ spinal nerves. Answer: 31 pairs of nerves arising from the spinal cord
◉ Ganglia. Answer: Small masses of nervous tissue consisting primarily
of neuron cell bodies that are located outside of the brain and spinal cord
◉ enteric plexuses. Answer: extensive networks of neurons located in
the walls of organs of the gastrointestinal tract
,◉ Sensory receptor. Answer: a structure of the nervous system that
monitors changes in the external or internal environment
◉ Somatic Nervous System (SNS). Answer: A component of the
peripheral nervous system; it transmits sensory signals and motor signals
between the central nervous system and the skin, muscles, and joints.
◉ autonomic nervous system (ANS). Answer: the part of the peripheral
nervous system that controls the glands and the muscles of the internal
organs (such as the heart). Its sympathetic division arouses; its
parasympathetic division calms.
◉ Enteric Nervous System (ENS). Answer: an independent neural
system involved with digestion; capable of signaling the brain regarding
stress and other emotions
◉ sympathetic division of ANS. Answer: Involved in preparing the body
for behavior, particularly in response to stress, by activating the organs
and the glands in the endocrine system (fight or flight)
◉ parasympathetic division. Answer: The branch of the autonomic
nervous system that generally conserves bodily resources
, ◉ sensory function of nervous system. Answer: The ability of the
nervous system to sense changes in either the internal or external
environment
◉ Integrative function of the nervous system. Answer: The ability of the
nervous system to analyze and interpret sensory information to allow for
proper decision making, which produces the appropriate response
◉ motor function of nervous system. Answer: Effects a change to
maintain homeostasis, brain tells effectors, causes muscles or glands to
take action in order to help maintain homeostasis
◉ Effectors of ANS. Answer: cardiac and smooth muscle, glands
◉ Neurons and Neuroglia. Answer: The two types of cells of the
nervous system are
◉ electrical excitability. Answer: the ability to respond to a stimulus and
convert it into an action potential
◉ Stimulus. Answer: Any change in the environment that is strong
enough to initiate an action potential
◉ Action potential (nerve impulses). Answer: An electrical signal that
propagates (travels) along the surface of the membrane of a neuron
