Question 1

The receptor potential is most accurately described as

the membrane potential produced when a neurotransmitter molecule binds to its receptor.

the membrane potential produced in the receptor cell by sensory transduction.

the ability of sensory receptors to detect sensation.

the electrical gradient produced by electromagnetic perception.

the acuity of chemoreceptors to bind to ions.

Question 2

Perception of sensory input occurs at the level of sensory receptors in peripheral tissues.

Question 2 options:

True

False

Question 3

In the sensory nervous system, multiple senses will share a given axon and the specific type of stimulus (temperature vs visual vs hearing) will be determined in somatosensory cortex of the brain.

Question 3 options:

True

False

Question 4

In nerve fibers that sense pressure, a small amount of pressure will result in a series of small action potentials, while more pressure will result in larger and larger action potentials.

True

False

Question 5

All sensor receptors are located in specialized epithelial cells that release neurotransmitter onto nearby sensory neurons, which then relay the sensory information into the central nervous system.

True

False

Solution

ans 1 B

Receptor potential is produced in receptor cell by sensory transduction. It is a depolarizing state that is caused due to inward flow of current. This current flow triggers the action potential in the excitory membrane.
