In most biological nomenclature, a scale ( Greek λεπίς lepis, Latin squama) is a small rigid plate that grows out of an animal 's skin to provide protection. Found insideThis book uses visual analogies to assist the student in learning the details of human anatomy and physiology. The integumentary system of vertebrates is genuinely a 'jack-of-all-trades' since it performs several essential functions, some of which are: Protection. - simple coiled tubular gland. the skin FUNCTIONS: 1. Nerve cord. Dentives abrasion, inhibits dehydration and protects the animals. They are bony plates that fit closely together or overlap and form the dermal skeleton.

The integument or skin separates the animal from its external environment and helps to maintain a constant internal environment. The skin of In all vertebrates the skin has two major layers. The integumentary system is the set of organs forming the outermost layer of an animal's body. Integumentary Derivative # 1. - epidermis: with unicellular mucous glands, mucoid cocoon, granular glaands, deep- sea fishes with photophores; dermis: with ganoid, cycloid, and ctenoid scales. - with uniform duct, and glandular portion. Fishes and amphibians have a mucus layer for bacterial and mechanical protection and to prevent drying on land. The integumentary system is a complex organ system composed of numerous components (skin, hair, nails, and glands). The integumentary derivatives are: 1. Denticles give cartilaginous fishes a sand paper texture. older outer layer separates from new epidermis. Their main problem is to prevent desiccation by water loss through the skin. The middle germ layer, or mesoderm, proliferates cells rapidly from segmental building blocks, called somites; these cells then migrate in order to lie directly under the outer ectodermal covering. This atlas gives an easy to understand insight into the morphology of the endocrine system and its adaptive and evolutionary aspects. The Integumentary System Integument is skin Skin and its appendages make up the integumentary system A fatty layer (hypodermis) lies deep to it Two distinct regions Epidermis Dermis Functions of skin Protection Cushions and insulates and is waterproof Protects from chemicals, heat, cold, bacteria Screens UV 2.
