Of the cell layers that compose the retina, which layer contains cells whose exons leave the eye at the optic disc to become the optic nerve?
Ganglion cell layer
The spiral organ is located within the [a] of the cochlear. This chamber is separated from the scala tympani by the [b], and separated from the scala vestibule by the [c], and is filled with a fluid called [d].

True or False-- The posterior pituitary gland arises embryonically as a downgrowth of the diencephalon of the brain, therefore it is nervous tissue.
This endocrine gland consists of a cortex and medulla, with each part embryonically derived from different tissues.
The parathyroid glands secrete parathyroid hormone in response to (increasing or decreasing) blood calcium levels.
