Question 1

Match the following receptors to their locations by using the answer code (options may be used more than once or not at all).
-receptors in taste buds

Accepted Answer

Choice Letter(s) or Number(s): A 
 Taste buds contain chemoreceptors that detect different compounds in food and send signals to the brain about their taste.

Question 2

Match the following receptors to their locations by using the answer code (options may be used more than once or not at all).
-receptors in otolith organs

Accepted Answer

Choice Letter(s) or Number(s): B

Otolith organs are responsible for detecting changes in linear acceleration and gravity.

Question 8

Match the following receptors to their locations by using the answer code (options may be used more than once or not at all).
-receptors in cochlea

Accepted Answer

Mechanoreceptors are sensory receptors that respond to mechanical stimuli such as pressure or vibration. The cochlea in the inner ear contains mechanoreceptors that respond to sound waves.

Answer: A and C 
 Chemoreceptors respond to chemical stimuli and are typically found in the nose and mouth for detecting taste and smell. However, there are also chemoreceptors in the cochlea that are involved in the detection of certain chemicals in the bloodstream that affect hearing. Photoreceptors are sensory receptors that respond to light stimuli and are found in the eye for detecting visual stimuli. However, there are also some photoreceptors located in the cochlea that are involved in regulating the body's circadian rhythm.

Question 9

Indicate the characteristics associated with each part of the ear by using the answer code (options may be used more than once or not at all).
-contains otoliths in gelatinous mass,movement of which bends hair cells

Accepted Answer

The utricle and saccule in the inner ear contain otoliths (small calcium carbonate crystals) in a gelatinous mass. Movement of the otoliths bends the hair cells, which then transmit sensory information to the brain about balance and orientation.

Question 10

Match the following receptors to their locations by using the answer code (options may be used more than once or not at all).
-receptors in semicircular canals

Accepted Answer

The receptors in the semicircular canals are mechanoreceptors, which detect changes in head rotation and movement.

Question 11

Indicate the characteristics associated with each part of the ear by using the answer code (options may be used more than once or not at all).
-contains the organ of Corti whose hair cells are bent during vibration of the basilar membrane

Accepted Answer

The cochlea in the inner ear contains the organ of Corti, which is responsible for transducing mechanical vibrations into electrical impulses that can be interpreted by the brain.

Answer: A 
 The external ear is responsible for collecting and directing sound waves towards the ear canal.

Answer: B 
 The middle ear contains the ossicles (the malleus, incus, and stapes) that transmit sound from the eardrum to the inner ear.

Answer: D 
 The semicircular canals in the inner ear are responsible for detecting changes in head rotation and orientation.

Answer: E 
 The utricle and saccule in the inner ear are responsible for detecting changes in linear acceleration and head position.

Question 12

Match the following receptors to their locations by using the answer code (options may be used more than once or not at all).
-receptors in retina

Accepted Answer

Photoreceptors are located in the retina, specifically the rods and cones which are responsible for detecting light and transmitting visual signals to the brain. Chemoreceptors detect chemical stimuli and are found in the taste buds and olfactory system, while mechanoreceptors detect mechanical stimuli and are found in the skin and inner ear.

Question 13

Match the following term with its description by using the answer code (options may be used more than once or not at all).
-measured in decibels

Accepted Answer

The intensity of a sound wave is measured in decibels, which refers to the loudness of the sound.

Question 14

Indicate the characteristics associated with each part of the ear by using the answer code (options may be used more than once or not at all).
-provides information useful for keeping the eyes focused on a fixed object even when the head is moving

Accepted Answer

The semicircular canals in the inner ear provide information about head rotation and help maintain balance by keeping the eyes focused on a fixed object even when the head is moving.

Answer: E
 The utricle and saccule in the inner ear are responsible for detecting linear acceleration and changes in head position, which helps maintain balance and spatial orientation.

Question 15

Match the following term with its description by using the answer code (options may be used more than once or not at all).
