Now examine the skin on the microscope slide 17 cornified skin, slide 18 pigmented skin using the 4X or 10X objective. Areas with a higher density of receptors should allow you to pinpoint touch more accurately than areas with fewer tactile receptors.
Is there a link between quantity of melanin and skin cancer? The density and distribution of tactile receptors varies from one part of your body to another. Remove one of the glass probes don t say which one! The touch should be gentle enough not to hurt, but firm enough to leave a small mark.
List some factors that promote the production of melanin besides DNA. In addition, the organs of the integumentary system are composed of many different tissues that perform common functions.

The integumentary system consists of a major organ, skin, and many epidermal derivatives (accessory organs), which include hair follicles, sebaceous glands, sweat glands, and nails.
In addition, the organs of the integumentary system are composed of many different tissues that perform common functions.Download
