The Sense Organs

Sense organs mainly for sensations such as pain, temperature, touch, and pressure

Cells that are activated by mechanical stimuli

Cells that are activated by chemical stimuli

A "Naked receptor"

Recptor in the muscles

Cells activated by light stimuli

Are distributed throughout the body and detect stimuli such as touch, pressure, temperature, position, and pain.

Specialized receptors found near the point of junction between tendons and muscles and others found deep within skeletal muscle tissue.

Nerve endings that have a type of connective tissue capsule surrounding their terminal or dendritic end.

Receptors produce an electrical signal or nerve impulse. This impulse is conducted by a sensory nerve to the appropriate area of the brain, where the sensation is perceived and interpreted.

Sense touch and pressure

Sense of touch and low frequency vibration

Sense of touch and possibly cold

Free nerve endings

Sense temperature
