Exam 45: Sensory Systems

Color vision is possible because of cones in the retina of the eye.There are three types of cones that can be stimulated by light.All other colors are combinations of the colors of three cones.The cone colors are: I-Red II-Yellow III-Orange IV-Blue V-Green VI-Purple

The retina of the human eye is composed of three layers of cells.Starting with the layer that is closest to the internal surface of the eyeball,what is the correct order?

In the vertebrate eye the amount of light reaching the retina is controlled by the

The brain interprets sound after which of the following sequential events? I-As the basilar membrane vibrates,the cilia of the hair cells bend in response to its movement relative to the tectorial membrane,the bending of the cilia depolarizes the hair cells. II-The hair cells stimulate the production of action potentials in sensory neurons that are projected to the brain. III-The axons of ganglion cells transmit action potentials to the occipital lobe of the brain.

All of the following are parts of the vertebrate eye except the

Select the incorrectly matched receptor and its function.

The lateral line system provides ________ with a sense of "distant touch," enabling these animals to sense objects that reflect pressure waves and low-frequency vibrations.

Color blindness is due to an inherited lack of cone receptors.These retinas typically contain

Choose the letter of the best match from the following: -Pacinian corpuscle.

In this figure,what is the best description for what is occurring?

Select the exception in the list of the following animals that are able to use sonar as a form of "lightless vision" to navigate in dark environments.

Free nerve endings,the simplest sensory receptors,respond to all of the following except

Interoceptors can recognize all of the following stimuli except

In this figure,where is the main transduction event occurring?

In the ear,high frequency sounds tend to

Which sense receptor cell directly produces an action potential?

In the vertebrate eye,the light is focused onto the

All of the following statements about the lateral line system in fish are correct except

Several types of mechanoreceptors are present in the skin.Two of the types are called phasic and tonic.Which of the following statements best describes the difference in phasic and tonic receptors?

__________ sense stimuli that arise from within the body.
