l1

Question 1

SS

Answer 1

(somatosensory) PNS afferent neuron sensing skin or skeletal muscle

Question 2

VS

Answer 2

(viscerosensory) ANS afferent neuron sensing organ or gland

Question 3

SM

Answer 3

(somatomotor) CNS efferent neuron that stimulates skeletal muscle

Question 4

BM

Answer 4

(branchiomotor) CNS efferent neuron that stimulates skeletal muscle also termed special visceral efferent (SVE) neuron

Question 5

VM

Answer 5

(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

Question 6

GN

Answer 6

(ganglionic neuron) = ANS efferent neuron that stimulates organ or gland collectively form autonomic ganglia = neuron in PNS that forms postganglionic fibre of the ANS

Question 7

invertebrate (e.g. drosophila) CNS=

Answer 7

brain + ventral nerve cord

Question 8

vertebrate (e.g. mouse) CNS=

Answer 8

brain + spinal cord

Question 9

invertebrate PNS

Answer 9

ventral, lateral, dorsal clusters
sensory originate independent of CNS

Question 10

vertebrate PNS

Answer 10

neural crest cells (NC) leave dorsal neural tube
NC generates sensory neurons (trunk region = DRG)

Question 11

invertebrate CNS motor neurons

Answer 11

generate in dorsal CNS

Question 12

vertebrate CNS motor neurons

Answer 12

generated in ventral CNS
somato-motor (SM) in pMN region

Question 13

invertebrate CNS do not have _____ neurons

Answer 13

branchio-motor

Question 14

vertebrate branchio-motor (BM) in ____ region

Answer 14

Vp3

Question 15

vertebrate ANS generated in ____

Answer 15

ventral CNS

Question 16

vertebrate ANS neural crest cells leave _____ and NC generates ____ neurons

Answer 16

dorsal neural tube
ganglionic
