Senses Lab Quiz

How are cold receptors different from heat receptors in terms of structure (touch part 2)?

• Cold receptors are unmyelinated, while heat receptors are myelinated

• Cold receptors are more common than heat receptors in the skin

• Cold receptors are free nerve endings with thick, myelinated fibers

• Heat receptors are free nerve endings with thin, myelinated fibers

How is the movement of the head detected by the inner ear (balance)?

• Through the movement of endolymph fluid which stimulates sensory hair cells

• By the vibration of the cochlea

• Through electrical impulses generated by the auditory nerve

• By pressure changes in the Eustachian tube

How many different odors can humans typically detect (smell part 1)?

• Over 1,000

What is the primary function of the olfactory epithelium (smell part 1)?

• To detect sounds
