Question 3

Match the receptors, labelled a. through c., to their locations. (Options may be used more than once or not at all.)
-semicircular canals

Accepted Answer

The semicircular canals, part of the inner ear, contain mechanoreceptors that detect head movements and changes in position, aiding in balance and spatial orientation.

Question 4

Match the terms, labelled a. through c., with their descriptions. (Options may be used more than once or not at all.)
-frequency of sound waves

Accepted Answer

The frequency of sound waves determines the pitch or tone of the sound, with higher frequencies producing higher pitches and lower frequencies producing lower pitches.

Question 5

Match the structures, labelled a. through h., with their proper sequence of involvement in the visual pathway.
-second

Accepted Answer

The answer of Match the structures, labelled a. through h.,...

Question 6

Match the ear parts, labelled a. through e., with their characteristics. (Options may be used more than once or not at all.)
-components aligned in three different planes all perpendicular to each other

Accepted Answer

The semicircular canals in the inner ear are the components aligned in three different planes all perpendicular to each other, which helps in maintaining balance by detecting rotational movements.

Question 7

Match the receptors, labelled a. through c., to their locations. (Options may be used more than once or not at all.)
-cochlea

Accepted Answer

The cochlea is part of the inner ear and is involved in hearing. It contains mechanoreceptors that convert mechanical sound vibrations into neural signals.

Question 8

Match the ear parts, labelled a. through e., with their characteristics. (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 are responsible for detecting rotational movements of the head and play a crucial role in maintaining balance and stabilizing vision during head movements. This helps in keeping the eyes focused on a fixed object even when the head is moving.

Question 9

Match the structures, labelled a. through h., with their proper sequence of involvement in the visual pathway.
-first

Accepted Answer

The answer of Match the structures, labelled a. through h.,...

Question 10

Match the terms, labelled a. through c., with their descriptions. (Options may be used more than once or not at all.)
-dependent on the amplitude of the sound wave

Accepted Answer

The intensity of a sound wave determines how loud a sound is perceived to be.

Answer: A
 The timbre or quality of a sound is dependent on the amplitude of the sound wave, among other factors such as harmonics and duration.

Answer: B
 Pitch, or tone, is determined by the frequency of a sound wave, not the amplitude.

Question 11

Match the ear parts, labelled a. through e., with their characteristics. (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, where hair cells are bent during the vibration of the basilar membrane, playing a crucial role in the process of hearing.

Question 12

Match the receptors, labelled a. through c., to their locations. (Options may be used more than once or not at all.)
-otolith organs

Accepted Answer

Otolith organs are a type of mechanoreceptor located in the inner ear that detect changes in head position and movement. Chemoreceptors detect chemicals, such as taste and smell, and are located in the nose and mouth. Photoreceptors detect light and are located in the retina of the eye.

Question 13

Match the ear parts, labelled a. through e., with their characteristics. (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 in a gelatinous mass. The movement of these otoliths causes the bending of hair cells, which helps to detect changes in head position and linear acceleration, such as when we move forward in a car or stand up from a seated position.

Question 14

Match the terms, labelled a. through c., with their descriptions. (Options may be used more than once or not at all.)
-measured in cycles per second

Accepted Answer

Pitch is measured in cycles per second (Hertz), which corresponds to the frequency of the sound wave. Higher frequencies result in higher pitches, while lower frequencies result in lower pitches.

Question 15

Match the receptors, labelled a. through c., to their locations. (Options may be used more than once or not at all.)
-retina

Accepted Answer

Photoreceptors are the type of receptors found in the retina. They are responsible for converting light into signals that can be interpreted by the brain, allowing for vision.

Question 16

Match the receptors, labelled a. through c., to their locations. (Options may be used more than once or not at all.)
-taste buds

Accepted Answer

Chemoreceptors are responsible for detecting chemical stimuli in the environment, which is how taste buds function by identifying different tastes.

Question 17

Match the terms, labelled a. through c., with their descriptions. (Options may be used more than once or not at all.)
-dependent on the overtones

Accepted Answer

Timbre refers to the quality of a sound, which is dependent on the overtones present in the sound.

Answer: B
 Pitch refers to the perceived highness or lowness of a tone, and is not necessarily dependent on the overtones.

Answer: C
 The intensity of a sound wave refers to its loudness, which is determined by the amplitude of the wave and is not necessarily dependent on the overtones.

Question 18

Match the ear parts, labelled a. through e., with their characteristics. (Options may be used more than once or not at all.)
-part of the vestibular apparatus

Accepted Answer

The answer of Match the ear parts, labelled a. through...

Question 19

Match the receptors, labelled a. through c., to their locations. (Options may be used more than once or not at all.)
-olfactory mucosa

Accepted Answer

Olfactory mucosa contains chemoreceptors responsible for detecting chemicals in the air, which are interpreted as smells.

Question 20

Match the terms, labelled a. through c., with their descriptions. (Options may be used more than once or not at all.)
-measured in decibels

Accepted Answer

Intensity of a sound wave is described in decibels.
