Cutaneous System Cutaneous system known as the skin, is our heaviest organ In 1953, Comel referred to skin as the “monumental façade of the human body” Our skin is made up of multiple layers, our outer skin is a layer of dead skin cells called epidermis. Below that layer is Dermis and within the skin are mechanreceptors The four mecahnorecptors are Merkel receptor and Meissner Corpsucle are located toward the surface of skin, while Ruffini Cylinder and Pacinan are deeper in the skin

Layers of Skin Epidermis is the outer skin layer made up of epithelial tissue. Consisting of keratin, melanocytes, Langerhans, and merkel cells. The papillary layer lies beneath epidermis, this is where the sense of pressure and temperature occurs. This layer of skin also gives flexibility. Epidermis has 5 layers of skin stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.

Dermis Layer Dermis is made of connective tissue. Depending on the location the thickness will vary. Made of collagen and elastin which gives the skin its flexibility. The epidermis is the strongest layer of the skin, and the stratum spinosum is the strongest layer of the epidermis. The reticular layer of the dermis is the strongest layer of the dermis. This layer has the most collagen and elasticity. Meissner nerve receptors in the dermis for light touch. Pacinian Corpuscle nerve receptors in the dermis for vibration and pressure

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
