Organ of Corti:

- basilar membrane (left most line)

- hair cells (3 lines in the gap)

- tectorial membrane (upside down lookin peninsula)

Pacinian corpuscles

gustatory

papillary layer - meissners corpuscles

taste buds

- gustatory cells (dark purple rly tiny)

- pore (surrounds the gustatory cells)

Anterior Chamber:

- cornea (outer ring)

- sclera

- zonule fibers (the hook like thing)
