Skin Senses Bruce Ayers/ Stone/ Getty Images The sense of touch is a mix of four distinct skin senses—pressure, temperature (warmth & cold), and pain.

Skin Senses Only pressure has identifiable receptors. All other skin sensations are variations of pressure, warmth, cold and pain. Pressure Burning hot Vibration Cold, warmth and pain

The Tactile Senses Touch Skin receptors that make us aware of how & where we’re being touched. Pressure Receptors beneath the skin that make us aware of deeper touch. Temperature Receptors are found just beneath the skin to give the sensation of hot, cold, and warm.

Brain areas involved in touch • somatosensory cortex – located in the parietal lobe

• Toothpick demo- difference threshold; pressure

Pain tells the body that something has gone wrong. Usually pain results from damage to the skin and other tissues. A rare disease exists in which the afflicted person feels no pain. AP Photo/ Stephen Morton Ashley Blocker (right) feels neither pain nor extreme hot or cold.

Biopsychosocial Influences on Pain

Gate-Control Theory Melzak and Wall (1965, 1983) proposed that our spinal cord contains neurological “gates” that either block pain or allow it to be sensed. Gary Comer/ Phototake. USA. com

Pain Control Pain can be controlled by a number of therapies including, drugs, surgery, acupuncture, exercise, hypnosis, and even thought distraction. Todd Richards and Aric Vills, U. W. ©Hunter Hoffman, www. vrpain. com

Touch • Receptors located in our skin. – Three sensations? – Touch, pressure, temperature • Gate Control Theory of Pain

Body Position and Movement The sense of our body parts’ position and movement is called kinesthesis. The vestibular sense monitors the head (and body’s) position. Bob Daemmrich/ The Image Works http: //www. heyokamagazine. com Whirling Dervishes Wire Walk

Grace and Balance The Kinesthetic Sense ±Keeps us informed about movement of body parts & their position in relation to each other. ±Muscle Movement, Posture, & Joints ±Information comes from stretch receptors, the tendons, & the internal organs.

Kinesthetic Sense • Tells us where our body parts are. • Receptors located in our muscles and joints. Without the kinesthetic sense you could touch the button to make copies of your buttocks.

Balance & Equilibrium Vestibular Sense • keeps us informed about • balance & the position of our body in space. Hair cells in the inner ear bend in relation to the position & movement of the head giving information that the brain uses to help us maintain our balance and to sense changes in our movement through space.

Vestibular Sense • Tells us where our body is oriented in space. • Our sense of balance. • Located in our semicircular canals in our ears.
