11

The olfactory bulb is where

the limbic area

12

what does the olfactory bulb contain

granular, mitral and tufted cells and a glomerulus

13

what is the nerve supply and path of olfaction

CN I to the cribriform plate of ethmoid bone to the lateral olfactory stria to the uncus or medial olfactory stria to the subcallosal gyrus

14

what is the main chemoreceptor for olfaction

Pseudo-stratified columnar epithelium on the upper surface of the superior concha

15

the retina develops from what

ectoderm

16

the sclera is derived from what

dura

17

the retinal cells include

Amacrine, bipolar, ganglion, horizontal, and pigments, rods and cones (rhodopsin)

18

what is the nerve supply and path of the optic nerve

Retina to the optic nerve to the optic chiasm to the optic tract to the lateral nucleus to the optic radiation to the calcarine fissure of the occipital lobe

19

In the retina what is the fovea centralis

center of the macula lutea which provides greates acuity and only contains cones
