Sensory Receptors Quiz Review

This diagram shows the process the body uses to respond to information received through the senses. Which of the following best describes the information that should fill in step 2?

• Information stored for later use

• Receptors respond to the information

• Information carried to the brain

• Body systems respond to the information

Sensory receptors in the skin have a different structure than sensory receptors in the eye. The most reasonable explanation for the difference in the structure of these receptors is that –

• there are many more sensory receptors in the skin than receptors in the eye.

• only the sensory receptors in the eye transmit signals directly to the brain.

• receptors in the skin are connected to nerve cells, but receptors in the eye are not.

• receptors in the eye respond to a different type of input than receptors in the skin.

How is the sense of smell related to memory?

• An organisms and populations with similar requirements for food, water, oxygen, or other resources may compete with each other.

• All organ systems depend on each other and all multicellular organisms follow the same levels of organization.

• Humans sense of smell has a strong connection to the brain that stores memories and emotions.

• Many predators have very good hearing that allows them to detect the movement of their prey.

The illustration below shows the structure of the human eye. The sensory receptors on the back of the eye react to light. The pupil is a hole in the iris, a structure in the front of the eye. Movements of the iris can cause the pupil to become larger or smaller. What observation would provide evidence for the claim that, by controlling the size of the pupil, the iris controls the amount of light that reaches the receptors in the eye?

• Other animals, such as fish and cats, have a pupil with a very different shape.

• The pupil becomes larger in dim light and smaller in bright light.

• There are no sensory receptors directly on the pupil at the front of the eye.

• Shining a bright light directly away from the eye causes no change in the pupil.

Which properties of nerve cells are most important for their ability to carry out their task in helping animals deal with sensory input?

• Nerve cells are sometimes packed closely together and sometimes widely spaced.

• Nerve cells can carry signals and connect all parts of the body to the brain.

• Nerve cells can be damaged by a serious injury or by disease.

• Nerve cells grow and reproduce like other cells of the body.
