Because of its importance to survival, the brain has a high concentration of pain receptors.

You feel hungry because of a proprioceptor.

Sensations produced by receptors of general senses are often called somatic senses.

Receptors are often described as sensitive axons or end organs.

An itch is caused by a rapidly adapting free nerve ending called a root hair plexus.

Which of the following is true about pain receptors?

Sensory receptors make it possible for the body to respond to stimuli caused by changes occurring in our external and internal environments.

If you slammed your finger in a car door, it would stimulate _____ pain fibers.

In referred pain, pain in a visceral organ is referred to skin sensors directly above it.

Encapsulated nerve endings are encapsulated by cuboidal epithelial tissue.

The treatment of fibromyalgia requires an increase of calcium ions in the pain centers of the spinal cord.

Pain that develops quickly and can be localized easily is called visceral pain.

Special senses tend to be grouped into localized areas.

The special senses:

Match each receptor type with its corresponding description. -Could be activated by a concentration of blood glucose

The word "deform" describes the stimulus detected by:

Mechanoreceptors are activated by stimuli that in some way deform or change the position of the receptor.

Describe each of the receptor categories, based on the types of stimuli that activate them.
