Nervous tissue

Question 1

nerve

look for:

fascicle

myelinated neuronal process (myelin sheath, endoneurium/neurolema, Schwann cell nucleus, Node of Ranvier)

connective tissue (endoneurium, perineurium, epineurium)

Answer 1

slide #39, and #6 or 9 (nerve in native setting)

Question 2

Auerbach’s myenteric plexus

autonomic ganglia linked together forms the myenteric plexus

between the two thick layers of smooth muscles

Answer 2

slides #6,9, or 11

Question 3

Spinal cord

gray matter

ventral horn, dorsal horn, central canal and surrounding ependymal cells

ventral motor neuron (in ventral horn) - perikaryon (cytoplasm), neuronal cell body/multipolar motor neuron, nissl substance/bodies (clumps of course granules in cell body/cytoplasm of ventral motor neurons

neuronal cell process (esp. in the neurophil) - axons and dendrites

neuroglial cells (strings stuff between ventral motor neurons in grey matter)

Answer 3

slide #40

Question 4

spinal cord

white matter

neuronal cell process (axons and dendrites)

meninges (exterior to CNS white matter) - pia mater (adheres directly to brain), arachnoid mater (delicate web-like), dura mater (tough and thick), dorsal root/dorsal root gagnlion

Answer 4

slide #40

Question 5

cerebral cortex has outer gray, inner white matter

gray matter - pyramidal cell

white matter -

Answer 5

slide #42

Question 6

cerebellar cortex

outer gray matter/inner white matter

gray matter - molecular layer (outer layer), purkinje cell layer, granular layer (inner layer, next to white matter)

white matter - note location next to granular layer of gray matter

Answer 6

slide #43
