Introduction to the Senses - A & P

The body contains millions of these that react difectly to stimuli from the environment.

What is the name for neurons that react to a specific stimulus sending impulses to other neurons, and eventually to the central nervous system?

Sensory receptors are located throughout the body but are concentrated in these.

These, within each organ, enable it to respond to a particular stimulus.

Pain receptors are located throughout the body except where?

These respond to chemicals released by damaged cells.

• pain receptors

• chemoreceptors

• photoreceptors

• thermoreceptors

This is important to recognize because it usually indicates danger, injury, or disease.

These sensory receptors are located in the skin, body core, and hypothalamus.

• thermoreceptors

• pain receptors

• mechanoreceptors

• chemoreceptors

These sensory receptors detect variations in temperature.

• thermoreceptors

• pain receptors

• photoreceptors

• mechanoreceptors

These sensory receptors are located in the skin, skeletal muscles, and inner ears.
