Chapter 15 Flashcards
Somatic nervous system
consciously percieved or controlled processes
somatic means
body
somatic sensory portion detects
signals from special senses and from skin and proprioreceptors
somatic motor porion sends
signals from CNS to skeletal muscles
voluntarty movemnets involve
cerebrum
reflexive movements involve
brainstem and spinal cord
peripheral nervous system is split into
sensory and motor
receive ____ from body and send signlas through those to impact movement
stimuli
body recieves sensroy signals from special sense known as
vision, hearing, equilibroium, smell, taste
proprioreceptors
stretch or distortion of things
conscious control sends signals to ______ muscle
skeletal
Autonomic nervous system is a type of
subcouncious or visceral control
visceral control means
regulated results below conscious level
visceral control caused by
viscera
ANS transmits signals from
CNS to heart, smooth muscle, and glands
we use autonomic nervous system to maintain
homeostasis
ANS responds to
visceral sensory inputs ( like blood vesels)
sensory neurons are not considered a part of the
ANS
ANS route
sensory receptors present and
send signal to ganglion
then sends to spinal cord,
then from spinal cord it can control regulation autonomically
divisions in ANS are
parasympathetic Division and Sympathetic division
Parasympathetic division
rest and digest; for conserving energy and replenishing nutrients
sympathetic nervous system
fight or flight; for exercis, excitement, or an emergency.
