Answer 4

balance, posture and coordination

Question 5

spinal cord

Answer 5

conduit for neural transmissions and reflex action

Question 6

axons morphology

Answer 6

unipolar, pseudo unipolar, bipolar and multipolar

Question 7

multipolar axons

Answer 7

pyramidal, Golgi and purkinje

Question 8

Golgi and purkinje axons

Answer 8

GABA neurons found in the cerebellum

Question 9

neurons anatomy

Answer 9

soma(cell body), axon and dendrites, neurofilaments and nucleus and do not divide

Question 10

astrocytes characteristics

Answer 10

able to proliferate
functions: structure-blood brain barrier
cell repair-synthesis of neurotrophic factors
homeostasis-neurotransmitter removal and uptake

Question 11

oligodendrocytes

Answer 11

produce internodes of myelin projections aka myelin sheath

Question 12

schwan cells

Answer 12

produce myelin on peripheral nerves

Question 13

microglial cells

Answer 13

immune functions in the CNS

Question 14

ependymal cells

Answer 14

epithelial cells lining fluid filled ventricles

regulate the production and movement of CSF

Question 15

neuroglia

Answer 15

oligodendrocytes, astrocytes, microglia, ependyma

Question 16

synaptic organisation

Answer 16

axodentritic synapse
axosomatic synapse
axoaxonic synapse

Question 17

axodendritic synapse

Answer 17

connection between presynaptic terminal and dendrite

Question 18

axosomatic synapse

Answer 18

connection between presynaptic terminal and cell body

Question 19

axoaxonic synapse

Answer 19

connection between presynaptic terminal and axons

Question 20

NMJ disorders

Answer 20

botulism, myasthenia gravis and Lambert-Eaton myastenic syndrome (LEMS)

Question 21

botulism

Answer 21

prevent Ach release from presynaptic nerve terminal

Question 22

myasthenia gravis

Answer 22

autoimmune disease that cause antibodies vs Ach receptor

Lambert-Eaton myastenic syndrome

Answer 23

autoimmune disorder that antibodies target VGCC
