A&P12 Nervous System III

Receptors for the general senses are found

• in a few clusters.

• only in the integumentary system.

• widely distributed throughout the body.

• throughout the visceral organs

Receptors for the special senses are found

• primarily in the head.

• throughout the integumentary system

• in the fingertips

• in internal organs

The brain interprets input from sensory receptors as

• reception

• sensation

• perception

• contraception

Sensory receptors include

• mechanoreceptors

• chemoreceptors

• photoreceptors

• all of these

The ability to ignore your socks around your ankles demonstrates

• general adaptation

• receptor integration

• interpretive assimilation

• sensory adaptation

The sequence of information flow in response to biting into a slice of pizza is

• perception, sensation, impulse send to CNS, sensory receptors activated

• sensory receptors activated, impulse sent to CNS, sensation, perception

• impulse sent to CNS, sensory receptors activated, perception, sensation

• impulse sent to CNS, sensory receptors activated, sensation, perception

Max returns to his dorm room late at night to find his roommate throwing up. The smell is at first so bad that Max wants to vomit too, but after helping his roommate clean up, the odor seems to fade. Max has experienced

• damage to his sensory receptors

• sensory adaptation

• a response to the decreasing concentration of odorant molecules in the room

• a hallucination

Sensory impulses are stimulated at receptors by

• neurotransmitters

• decreasing permeability of nerve cell membranes

• sub-threshold potential

• local changes in their cell membrane potentials

Olfactory receptors, which provide the sense of smell, are

• thermoreceptors

• mechanoreceptors

• chemoreceptors

• proprioceptors

A sensation is ______, and projection of a sensation is the ______.

• the stimulation of a receptor cell; transmission of an impulse into the brain

• a feeling that results from sensory stimulation; brain causing it to seem to come from the receptors being stimulated

• a good feeling from a stimulation; right side of the brain projecting the sensation to the left side, or vice versa

• a change in membrane permeability of a receptor; transmission of an impulse into a sensory area of the brain
