Question 1

A cell that responds when light hits it is called:&#10;A) A neuron&#10;B) A photoneuron&#10;C) A photoreceptor&#10;D) A sensorireceptor&#10;E) A relay neuron

Accepted Answer

Photoreceptor is a type of sensory receptor that responds to light. A neuron is a type of cell in the nervous system that transmits electrical signals, but it does not respond directly to light. Photoneuron is not a commonly used term. Sensorireceptor is not a term commonly used in biology. Relay neuron is a type of neuron that passes information between different neurons, but it does not directly respond to light.

Question 2

What is the thickness of the retina?&#10;A) .1mm&#10;B) .2mm&#10;C) .3mm&#10;D) .4mm&#10;E) .5mm

Accepted Answer

The thickness of the retina ranges from .1mm to .5mm, but the average thickness is around .2mm. Therefore, option B (.2mm) is the best and most accurate choice.

Question 3

How many different light colors are at the base of our experience of color?&#10;A) 1&#10;B) 2&#10;C) 3&#10;D) 4&#10;E) 5

Accepted Answer

D

Question 4

What determines the pitch of a sound?&#10;A) Volume&#10;B) Intensity&#10;C) Amplitude&#10;D) Frequency&#10;E) Timbre

Accepted Answer

The pitch of a sound is determined by its frequency, which is the number of cycles per second of the sound waves. Higher frequencies result in higher pitches, while lower frequencies result in lower pitches. Volume, intensity, amplitude, and timbre all play a role in the characteristics of a sound, but do not determine its pitch.

Question 5

Which of these is NOT part of the auditory pathway in the brain?&#10;A) Concha&#10;B) Superior olive&#10;C) Inferior colliculus&#10;D) Medial geniculate nucleus&#10;E) Primary auditory cortex

Accepted Answer

The concha is an anatomical structure in the outer ear that helps to collect and direct sound waves towards the ear canal. However, it is not part of the auditory pathway in the brain, which involves structures from the cochlea (in the inner ear) to the primary auditory cortex (in the temporal lobe). The other options listed (superior olive, inferior colliculus, medial geniculate nucleus, and primary auditory cortex) are all part of this pathway.

Question 6

What are the two pathways between the auditory and prefrontal cortex know as?&#10;A) What and who&#10;B) What and where&#10;C) Who and where&#10;D) When and what&#10;E) When and where

Accepted Answer

The two pathways between the auditory and prefrontal cortex are known as the "what" pathway and the "where" pathway. The "what" pathway processes the identity and characteristics of sounds, while the "where" pathway processes the spatial location of sounds. Therefore, choice B ("What and where") is the correct answer.

Question 7

Which of the touch receptors is associated with controlling hand grip?&#10;A) Merkel&#10;B) Ruffini&#10;C) Meissner&#10;D) Pacinian&#10;E) Root hair

Accepted Answer

Meissner's corpuscles are responsible for detecting light touch and changes in texture, which are important for controlling hand grip.

Question 8

The cells related to the experience of pain outside of the brain are referred to as:&#10;A) Pain receptors&#10;B) Somatosensory receptors&#10;C) Parietal receptors&#10;D) Nociceptors&#10;E) Sensory receptors

Accepted Answer

Nociceptors are sensory neurons that are specialized to detect and transmit signals related to tissue damage or potential damage, which can result in the sensation of pain. These cells are located in various tissues throughout the body, including the skin, muscles, and organs, and are responsible for detecting stimuli such as heat, cold, pressure, and chemicals that can cause tissue damage. While nociceptors transmit signals related to pain, it is the brain that ultimately processes and interprets these signals to create the experience of pain.

Question 9

Which of these areas in the central nervous system is not involved in our experience of pain?&#10;A) Insula&#10;B) Cingulate&#10;C) Spinal cord&#10;D) Thalamus&#10;E) Temporal

Accepted Answer

The temporal area is not involved in our experience of pain. The other areas listed are all known to be involved in the processing and experience of pain.
