Sensory process, the skin senses. Submitted to: Professor Kumara By: Fizz khan Class: BIBB Roll no: 0008 Sensory process: The skin senses 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. The sensitivity is greatest on people’s faces, tongues, and hands, allowing for effective eating, speaking, and grasping through the precise sensory feedback that is given in these areas.

When you are liking in a store and people are walking by you, you feel the breeze of them passing by and get a cold chill. Touching a hot stove and feeling the heat against the skin on your hand. Feeling the pain of a sharp object on your skin. Walking into a big freezer, full of every ice cream you could think of, your body all around feels the coldness of the freezer. Skin senses includes following parts 1 .

Coetaneous senses or senses of touch 2. Somatic sense 3. Anatomic sensory system Coetaneous senses or senses of touch:- the faculty by which external objects or forces are perceived through contact with the body (especially the hands); “only eight and touch enable us to locate objects in the space around us”. Sensitivity to stimuli originating outside of the body. The skin contains receptors that respond to touch, pressure, and temperature. The relationships between receptors and the Coetaneous sensations are not completely understood.

Missioner’s corpuscles are sensitive to touch and Pacing corpuscles to deep pressure. Ruffian endings transmit information about warmth and Karate’s bulbs about cold. Information is transmitted from the receptors toner fibers that are routed through the spinal cord to the brainstem. From there they are transmitted to an area of cortex in the parietal lobe. Skin senses also undergo various kinds of sensory adaptation. For example, a hot tub can be initially so hot that it is intolerable, but after awhile one can sit in it without discomfort. Moat sense:- any of the sensory systems that mediate sensations of pressure and tickle and warmth and cold and vibration and limb position and limb movement and pain. Somatic sensory system:- the faculty of bodily perception; sensory systems associated with the body; includes skin senses and preconception and he internal organs. To meet a wide array of sensory demands, many kinds of specialized receptors are required. Somatic sensory receptors range from simple, bare nerve endings to complex combinations of nerve, muscle, connective tissue, and supporting cells.

As we have seen, the other major sensory systems have only one type of sensory receptor or a set of very similar subtype. How a body can feel pain , hot or cold and pressure.? Experience of cold and warmth are elicited by changes in the normal gradient of skin temperature, that is by the changes in the difference between the imperative of the skin surface and the temperature of the blood circulating beneath it.. Pain is a skin sense, but it felt from the interior of the body too.

Many different stimuli produces pain, the pain is called noxious because of the close relationship between pain and bodily injury. Pain stimuli can damage bodily tissues in some way. The nerve fibers that carry information about pain into the spinal cord and brain are the smaller diameter fibers in the sensory nerves from the skin and body organs. The sensation a person who is touched lightly on the skin reports is called either pressure or touch. The amount of physical pressure required to produce this experience varies greatly for different parts of the body.

With touch, a person is detecting mechanical energy, or pressure against the skin. Sensory fibers from receptors in the skin enter the spinal cord, from which the information travels to the brain stem. At the brain stem most fibers from the body cross over to the opposite side of the brain. The brain devotes more area to interpreting touch from the hands than it does from the legs. Newborns can experience touch better than they can see, hear, or taste. Females are more sensitive to touch than are males.
