The Skin Senses (Its Parts and Sensory Functions)

1. THE SKIN SENSES- Its parts and Sensory
Functions

2.  Skin – it contains the largest receptors of any
sensory system in the human body because it covers
the entire body. There are sensitive spots that are
distributed in different places of the skin where one
feels the primary cutaneous sensations like pressure,
pain, warmth, and cold. Free nerve endings, Ruffini’s
ending , Krause and Bulb, Pacinian Corpuscles,
merkel’s disk and meissner’s corpuscles peritrichial
are the receptors of the skin.

4. Functions of the Skin or the Sensory
Functions
 Sensory receptors respond to stimuli and transmit data about them
to the brain. In the skin, receptors detect touch, pressure, vibration,
temperature, and pain. Elsewhere in the body, more specialized
receptors detect light , sound, smell, and taste. Internal receptors
called proprioceptors sense body position and the location of body
parts in relation to each other.
 Skin senses - are sensory systems for processing touch, warmth, cold,
texture, and pain. They begin with external contact but then are
transformed after being picked up by the nerve endings in the skin.
-is an important sense which enhances a person’s chances for survival. If
a person were unable to respond to pain or pressure stimuli, for example,
it would be possible for him to be covered by wounds and bruises before
he becomes aware that he has been hurt because his sense of touch
which would ordinarily warm him is absent.
