Human Neural System Flashcards
two parts of human neural system
central neural system
peripheral neural system
which neural system is the site of information processing and control
cns
what does cns constitute
brain, spinal cord
two types of pns nerve fibres
afferent
efferent
what do afferent nerve fibres do
transmit impulses from tissue / organ to cns
what do efferent nerve fibres do
transmit impulses from cns to tissues / organs
two divisions of pns
somatic neural system
autonomic neural system
sns relays impulses from __________ to ___________
cns
skeletal muscles
ans relays impulses from ________ to _____________
cns
involuntary organs and smooth muscles
ans is divided into
sympathetic neural system
parasympathetic neural system
visceral nervous system is a part of which nervous system
