Types of
Receptors
 _____________________-receptors stimulated by changes
in the chemical conc. Of substances
 _________ receptors-receptors stimulated by tissue damage
 _________receptors-receptors stimulated by changes in
temperature
 ___________receptors-receptors stimulated by changes in
pressure or movement
 _________receptors-receptors stimulated by light energy
Touch
Receptors
 _____________ nerve fibers-receptors common throughout
the skin (epithelium)-sensations of touch and pressure on the
skin surface
 _________________________-receptors found on hairless
portions of the skin (lips, palms, fingertips, soles, nipples and
genital organs)-sensations include the motion of objects that
barely contact the skin (_________ touch)
 __________________-large receptors located in the
subcutaneous tissue, muscle tendons, and joint ligamentssensations of________ pressure (heavy pressure)
Temperature
Receptors
 Warm receptors-receptors sensitive to temperatures
over_____ C and are nonresponsive over 45 C (stimulates pain
receptors-burning)
 Cold receptors-receptors sensitive to temperatures between temperatures below ____ C stimulates pain receptors-freezing
Pain
Receptors
 Widely distributed throughout the skin and internal tissues,
except in __________ (no receptors for pain)
 Protect body against tissue damage
