The skin’s primary role is to help protect the rest of the body’s tissues and organs from physical damage such as abrasions, chemical damage such as detergents, and biological damage from microorganisms. The membrane that composes the peritoneum and the pericardium is mucus. Q. answer choices . The amount of oxygen-saturated hemoglobin found in the blood vessels of the middle layer of our skin, the dermis. Serous fluid= between layers. answer choices . Mucous (mucosa) membranes line the insides of hollow organs that open to the outside. Term: Muscular Tissue Definition: Composed of cells called muscle fibers and myocytes. The middle layer of skin, the dermis, contains blood vessels, nerves, and glands that are important for our skin’s function. Melanocytes are irregularly shaped cells that produce and store a pigment called melanin. The epidermis provides a protective waterproof barrier that also keeps pathogens at bay and regulates body temperature. The cutaneous membrane refers to the skin or the integument, that covers the external surface of the body. In order from the deepest layer of the epidermis to the most superficial, these layers (strata) are the: Skin overview: Skin layers, of both hairy and hairless skin. The former help contribute to body odor (along with the bacteria on our skin), and the latter help regulate our body temperature through the process of evaporation. Create your account.

Hypodermis (Subcutaneous layer) layer - Lies below the integument and stabilizes the skin, made of elastic areolar and adipose tissues Connected to the reticular layer of integument by connective tissue fibers, few capillaries and no vital organs, the site of subcutaneous injections using hypodermic needles This is where the skin’s most important cells, called keratinocytes, are formed before moving up to the surface of the epidermis and being shed into the environment as dead skin cells. Functions of the epidermis include touch sensation and protection against microorganisms. Mucous: Lines all body cavities that open to the exterior body surface. Both the nutrient supply and temperature regulation occur thanks to an extensive network of blood vessels in this layer. The apical surface of this membrane is exposed to the external environment and is covered with dead, keratinized cells that help protect the body from desiccation and pathogens. Epidermis : This forms the outer layer of the skin, and is a structure made up of keratinized stratified squamous epithelial cells. It is a stratified squamous epithelial membrane resting on top of connective tissue. The cutaneous membrane is the technical term for our skin. The dermis consists of a papillary and a reticular layer that serve to protect and cushion the body from stress and strain. It is the layer we see with our eyes. Skin = Integument = Cutaneous Membrane 7 Functions: 1.

(adsbygoogle = window.adsbygoogle || []).push({}); The skin is the soft outer covering of vertebrates that guards the underlying muscles, bones, ligaments, and internal organs.
