Visual Pathway

1)Retina
2)Optic Nerve
3)Optic Chiasm
4)Optic Tract
5)Optic Radiations
6) Lateral Geniculate Nucleus(LGN) of the thalamus
7a) (startle reflex) superior colliculus
7b) visual cortex


Auditory Pathway:

1) Pinna/Auricle 
2) External Auditory Canal
3) Tympanic Membrane
4) (Malleus-->Incus-->Stapes)::ossicles

6) vibrations in perilymph
7) basilar membrane
8) organ of corti
9) vestibulocochlear nerve
10) brain stem
11) medial geniculate nucleus(MGN) of the thalamus
12a) (startle reflex) inferior colliculus
12b) superior olive
13b) auditory cortex

Olfactory pathway:
 
1) nasal passages
2) olfactory nerves in olfactory epithelium
3) olfactory bulb
