l1 Flashcards
SS
(somatosensory) PNS afferent neuron sensing skin or skeletal muscle
VS
(viscerosensory) ANS afferent neuron sensing organ or gland
SM
(somatomotor) CNS efferent neuron that stimulates skeletal muscle
BM
(branchiomotor) CNS efferent neuron that stimulates skeletal muscle also termed special visceral efferent (SVE) neuron
VM
(visceromotor) ANS efferent neuron that stimulates organ or gland also termed general visceral efferent (GVE) neuron = neuron in CNS that forms preganglionic fibre of the ANS
GN
(ganglionic neuron) = ANS efferent neuron that stimulates organ or gland collectively form autonomic ganglia = neuron in PNS that forms postganglionic fibre of the ANS
invertebrate (e.g. drosophila) CNS=
brain + ventral nerve cord
vertebrate (e.g. mouse) CNS=
brain + spinal cord
invertebrate PNS
ventral, lateral, dorsal clusters
sensory originate independent of CNS
vertebrate PNS
neural crest cells (NC) leave dorsal neural tube
NC generates sensory neurons (trunk region = DRG)
invertebrate CNS motor neurons
generate in dorsal CNS
vertebrate CNS motor neurons
generated in ventral CNS
somato-motor (SM) in pMN region
invertebrate CNS do not have _____ neurons
branchio-motor
vertebrate branchio-motor (BM) in ____ region
Vp3
vertebrate ANS generated in ____
ventral CNS
