The photoreceptors are located in the vascular tunic of the eyeball.

Explanation / Answer

a) Damage to the inner ear or the vestibulo cochlear nerve causes sensorineural hearing loss. So, the given statement is false.

b) The diameter of the iris is controlled by sphincter pupillae and dilate pupillae. Ciliary muscle acts to change the focus of lens. So, the given statement is false.

c) The Weber and Rinnes test assess the conductive and sensorineural hearing loss. So, the given statement is false.

d) The eyeball movement is caused by six extraocular muscles: superior and inferior obliques and four rectus muscles. So, the given statement is true.
