Free nerve endings control the sensation of


Meissner's (tactile) corpuscles are sensitive to

Light touch

Sensory receptors that respond to heavy pressure called

Pacinian corpuscles

Gustatory receptors are located

on the tongue's surface

Primary taste sensations are


The sensory portion of the gustatory organ is (are) the

taste hairs

The tip of the tongue is the site of taste cells for


The branch of the cranial nerves which is responsible for monitoring changes in equilibrium is

The vestibular branch

How many semicircular canals are in the inner ear?


The sense of hearing is provided by the receptors of the

inner ear

The malleus bone is attached to the

tympanic membrane

The basic receptors in the inner ear are the

hair cells

A structure that allows the connection of the middle ear to the nasopharynx is the

auditory tube
