Question 1

Hair cell receptors are found in the auditory, vestibular, and somatosensory systems.

Accepted Answer

Hair cell receptors are sensory receptors that are found in the inner ear and are responsible for hearing and balance. They are also found in the skin and are responsible for touch.

Question 2

Object recognition and perception of motion are functions of the primary visual cortex.

Accepted Answer

Information that has been processed in the primary visual cortex is projected to the temporal and parietal lobes for "what" and "where" processing.

Question 3

Loss of smell is common in brain injury because of the fragility of the olfactory nerve fibers.

Accepted Answer

The olfactory nerve fibers, which are responsible for the sense of smell, are very delicate and can easily be damaged during a brain injury, leading to a loss of smell.

Question 4

All sensory systems project first to the thalamus before going to a region of the cortex.

Accepted Answer

The olfactory system projects first to the cortex.

Question 5

Many young children who are "picky eaters" will grow out of this behavior with no intervention.

Accepted Answer

Most children go through phases of picky eating, and it is a normal part of development. With time and exposure to a variety of foods, many outgrow this behavior without the need for specialized intervention.

Question 6

Sensory sensitivities are often associated with feeding and eating challenges, especially in children with developmental disorders.

Accepted Answer

Sensory sensitivities can affect how children with developmental disorders perceive the taste, texture, smell, and appearance of food, leading to feeding and eating challenges.

Question 7

The ability to modulate incoming sensory information is primarily dependent on cortical structures.

Accepted Answer

It is dependent on the subcortical structures-midbrain and thalamus.

Question 8

Accepted Answer

The utricle and saccule are part of the otolith organs, which are responsible for detecting linear acceleration and head position relative to gravity, not the semi-circular canals which detect rotational movements.

Question 9

For each of the following statements, put a "O" if the statement BEST describes the structure or function of the otolith organs; put an "S" if the statement BEST describes the structure or function of the semi-circular canals.
-Respond to rotation and angular movement of the head

Accepted Answer

The semi-circular canals are specifically responsible for detecting angular movement and rotation of the head, which is why statement B is correct.

Question 10

For each of the following statements, put a "O" if the statement BEST describes the structure or function of the otolith organs; put an "S" if the statement BEST describes the structure or function of the semi-circular canals.
-Oriented in horizontal and vertical planes

Accepted Answer

BThe otolith organs (utricle and saccule) are oriented in horizontal and vertical planes, respectively, and are responsible for detecting linear acceleration and head position relative to gravity. The semi-circular canals are oriented in three roughly orthogonal planes and are responsible for detecting angular acceleration or rotation of the head.

Question 11

For each of the following statements, put a "O" if the statement BEST describes the structure or function of the otolith organs; put an "S" if the statement BEST describes the structure or function of the semi-circular canals.
-Respond to head tilt in any direction and to linear movement

Accepted Answer

The otolith organs (utricle and saccule) are responsible for detecting linear acceleration and head tilts, which helps in maintaining balance and understanding orientation in space.

Question 12

For each of the following statements, put a "O" if the statement BEST describes the structure or function of the otolith organs; put an "S" if the statement BEST describes the structure or function of the semi-circular canals.
-Receptor cells located in ampulla

Accepted Answer

The semi-circular canals contain the ampullae, which house the receptor cells (hair cells) that detect angular acceleration and head rotation. The otolith organs, on the other hand, are responsible for detecting linear acceleration and head position relative to gravity.

Question 13

For each of the following statements, put a "O" if the statement BEST describes the structure or function of the otolith organs; put an "S" if the statement BEST describes the structure or function of the semi-circular canals.
-Important for upright tonic posture and support reactions

Accepted Answer

The otolith organs (utricle and saccule) are essential for detecting linear accelerations and head tilts, which are crucial for maintaining upright tonic posture and support reactions. The semi-circular canals, on the other hand, are primarily responsible for detecting angular accelerations related to head rotations.

Question 14

For each of the following statements, put a "O" if the statement BEST describes the structure or function of the otolith organs; put an "S" if the statement BEST describes the structure or function of the semi-circular canals.
-Important for righting responses and phasic equilibrium

Accepted Answer

The semi-circular canals are primarily responsible for detecting rotational movements and are crucial for maintaining balance during movement, making them important for righting responses and phasic equilibrium. The otolith organs, on the other hand, detect linear accelerations and head tilts in relation to gravity.

Question 15

For each of the following statements, put a "O" if the statement BEST describes the structure or function of the otolith organs; put an "S" if the statement BEST describes the structure or function of the semi-circular canals.
-Anterior, posterior, and horizontal tubes

Accepted Answer

The anterior, posterior, and horizontal tubes refer to the semi-circular canals, which are part of the inner ear involved in detecting rotational movements.

Question 16

For each of the following statements, put a "R" if the statement BEST describes the structure or function of rods; put a "C" if the statement BEST describes the structure or function of cones.
-Color vision

Accepted Answer

Cones are responsible for color vision, while rods are more sensitive to light and are used for vision in low light conditions.

Question 17

For each of the following statements, put a "R" if the statement BEST describes the structure or function of rods; put a "C" if the statement BEST describes the structure or function of cones.
-Day vision

Accepted Answer

Cones are responsible for color vision and function best under bright light conditions, making them crucial for day vision.

Question 18

For each of the following statements, put a "R" if the statement BEST describes the structure or function of rods; put a "C" if the statement BEST describes the structure or function of cones.
-Night vision

Accepted Answer

Rods are responsible for vision in low light conditions, which is why they are associated with night vision.

Question 19

For each of the following statements, put a "R" if the statement BEST describes the structure or function of rods; put a "C" if the statement BEST describes the structure or function of cones.
-Peripheral vision

Accepted Answer

Rods are more numerous in the peripheral regions of the retina and are primarily responsible for peripheral vision.
