Red arrows-Pyramidal cells. Note processes (less extensive than Purkinje cells), cell body tends to have pyramidal appearance.

Question 7

Answer 7

Peripheral Nerve

Question 9

Answer 9

Autonomic ganglia - Peripheral nervous system. Differ from spinal ganglia by having multipolar neurons with dendrites.

Question 10

Answer 10

TIght Junction (zona occludens)

Question 11

Answer 11

choroid epithelial cell - neuroglia - red arrows indicate RBCs

Question 12

Answer 12

Dorsal Root Ganglion (large pseudounipolar neurons - look for tightly packed neurons with lots of satellite cells)

Question 13

Answer 13

Myoepthelial Cells - unlabeled arrow points to them

Question 13

Answer 13

Purkinje cells (cerebellum) Red arrows -cell bodies (see large dendritic trunk with branches-tree) Blue arrows - axons of the Purkinje cells

Question 13

Answer 13

Skeletal Muscle - Black Arrows are A Bands (dark staining) BLue arrows are Z lines within A bands

Question 14

Answer 14

Glial cell (support of nervous system) Red arrows-astrocytes (see fine processes from cell body)

Question 15

Answer 15
