Nerves Summary Flashcards
General Visceral Afferent (GVA) receives or delivers
Received info from organs and blood vessels to tell brain what’s happening
General visceral Afferent (GVA) arrives/originates
Arrived in dorsal grey horn of spinal cord
GVA type of neuron
Psuedounipolar
General Visceral Efferent (GVE) delivers/receives
Delivers info to smooth muscle that surrounds organs and blood vessels to tell them to alter function
General Visceral Efferent (GVE) originates/arrives
Originates in lateral grey horn in spinal cord and go out into the body
GVE neuron
Multipolar neurons have to synapse twice
General somatic Afferent (GSA) receives/delivers
Receives proprioceptive and functional info from muscles
General somatic Afferent (GSA) arrive/ originate
Arrive in dorsal grey horn of spinal cord
GSA neuron type
Pseudounipolar neurons
GSA proprioceptive information runs with GSE fibers
General Somatic Efferent (GSE) deliver/receives
Delivers motor commands to musculature
General somatic Afferent (GSE) originate/arrive
Originate in ventral grey horn of spinal cord and go out to the body through ventral root
General somatic efferent (GSE) neurons
One neuron extends from CNS to muscle fibers involved
GSE controls
Striated skeletal muscle
Voluntary movement
GSA relays what info
Sensory info
Motor neurons contain
GSE, GSA, GVA, GVE
Sympathetic nerves always start where
Lateral grey horn on thoracolumbar portion
Parasympathetic nerves always start
In brain or sacral portion of spinal cord
Sympathetic always synapse in
Last available ganglion
Parasympathetic always synapse
In plexus near or inside wall of target organ
Cutaneous nerves contain
GVA, GVE, GSA
