Question 1

How do rods differ from cones in the retina? ​

Accepted Answer

Cones can detect color, while rods cannot. Additionally, rods are more sensitive to light than cones and are optimally activated by light entering the periphery of the eye. Neither rods nor cones provide the ability to see sharper images - that is the function of the lens and cornea.

Question 2

Visible light is a type of ____. ​

Accepted Answer

Visible light is a form of electromagnetic radiation, which is a type of energy that travels in waves. It is part of the electromagnetic spectrum, which also includes other types of radiation such as radio waves, microwaves, infrared radiation, ultraviolet radiation, X-rays, and gamma rays.

Question 3

The clear surface at the front of the eye that begins the process of directing light to the retina is the ____.

Accepted Answer

The cornea is the clear, dome-shaped surface that covers the front of the eye and plays a crucial role in focusing light onto the retina.

Question 4

Maria is the victim of an armed robbery. She is called into the police station to identify her assailant from a line-up of men. She correctly reports that none of the men were her attacker. This illustrates the concept of a(n)____. ​

Accepted Answer

Maria correctly rejected each member of the line-up as not being her attacker. This is referred to as a correct rejection, which is an important factor in maintaining the integrity of eyewitness identification evidence.

Question 5

Hugo is running an experiment to determine if a specific DNA allele is present in a new transgenic mouse line. He glances through numerous data sets and identifies the correct DNA "band" in the majority of his experiments. This illustrates the concept of a ____.

Accepted Answer

A "hit" refers to identifying the correct result or outcome in an experiment, which is exactly what Hugo is doing by identifying the correct DNA band in the majority of his experiments.

Question 6

Marcella gets up early, turns on the light in the bathroom, and watches herself in the mirror as the blue ring of her eyes constrict. What is this blue ring called? ​

Accepted Answer

The blue ring of the eyes is called the iris, which is the colored part of the eye surrounding the pupil.

Question 7

After suffering an eye injury during a lacrosse match, Gregg is forced to wear an eye patch. In addition to problems with depth perception, Gregg's ophthalmologist tells him that his blind spot will be more evident. Which structure of the eye has been affected with regard to his blind spot?

Accepted Answer

The optic disk is the part of the retina where the optic nerve exits the eye, creating a natural blind spot because it lacks photoreceptors.

Question 8

Where does the optic nerve cross the midline? ​

Accepted Answer

The optic nerve fibers cross the midline at the optic chiasm, allowing visual information from each eye to be processed by both hemispheres of the brain.

Question 9

Which structure of the eye is responsible for detecting light? ​

Accepted Answer

The retina is the structure in the eye that contains photoreceptor cells, which are responsible for detecting light and converting it into neural signals.

Question 10

Of the following, who is likely to have the most rods activated in the retina? ​

Accepted Answer

The answer of Of the following, who is likely to...

Question 11

What is the role of the amygdala in processing visual information? ​

Accepted Answer

The amygdala is known to play a role in processing emotional information, and it has been shown to make quick emotional judgments about visual stimuli. For example, the amygdala can quickly recognize a fearful facial expression and trigger a fear response in the body.

Question 12

An area of the retina that is specialized for fine detailed vision is referred to as the ____. ​

Accepted Answer

The fovea is a small area in the center of the retina that contains a high density of cone cells, which are specialized for detecting fine details and colors in bright light conditions. This makes it the part of the retina that is responsible for our sharpest visual acuity. The lens and cornea help to focus light onto the retina, while the optic disk is where the nerve fibers that carry visual information exit the eye, creating a blind spot in our visual field. Thus, neither of these options would be considered specialized for fine detailed vision.

Question 13

Seth is involved in an automobile accident and suffers damage to his parietal lobe. How may this affect his ability to process visual information? ​

Accepted Answer

The answer of Seth is involved in an automobile accident...

Question 14

How does the brain process visual information? ​

Accepted Answer

Visual information travels from the retina to the thalamus and then to the primary visual cortex in the occipital lobe. The amygdala is involved in processing emotions related to visual stimuli.

Question 15

Which feature of the eye is analogous to a hole in the center of a donut? ​

Accepted Answer

The pupil is the opening in the center of the iris that allows light to enter the eye, similar to a hole in the center of a donut.

Question 16

The best analogy for light energy is: ____. ​

Accepted Answer

Light energy behaves like waves, similar to how waves propagate in the ocean.

Question 17

Adele is planning to paint the walls in her room over spring break. She studies several color samples and is trying to decide between yellow, green, and blue hues. What light wave attribute allows Adele to differentiate between these colors? ​

Accepted Answer

The wavelength of light waves determines the color perceived by the human eye, allowing Adele to differentiate between yellow, green, and blue hues.

Question 18

What important fact supports the idea that vision is one of the most important sensory systems in humans? ​

Accepted Answer

Approximately 50% of our cerebral cortex processes visual information, highlighting the importance of vision in human sensory processing.

Question 19

Adele decides to paint her room green. She studies several bright green and pastel green color samples. What attribute of the light wave allows Adele to differentiate between these light intensities? ​

Accepted Answer

The amplitude of waves determines the intensity or brightness of the color, allowing Adele to differentiate between bright and pastel greens.

Question 20

In what orientation are images projected onto the retina? ​

Accepted Answer

Images are projected onto the retina upside down and reversed because the lens of the eye inverts the image.
