Matching : Matching

The Integumentary System : The Integumentary System Made up of the skin and the appendages of the skin: The glands The hair The nails

The basic structure of skin : The basic structure of skin Keratinized cells papillae epidermis dermis

Dermal Papillae : Dermal Papillae The dermal papillae allow for maximum blood flow to the basement membrane. This helps the epidermal cells get the nutrients they need.

Why do we scar? : Why do we scar? If a cut is along the skin’s lines of cleavage, there is not much tension on it… So the cut can heal quickly with little scarring If a cut goes across the lines of cleavage, there is tension… Pulling it apart making it harder to heal and more likely to scar

How burns affect the skin : How burns affect the skin

Tissue present in the hypodermis : Tissue present in the hypodermis

Function of sebaceous glands : Function of sebaceous glands Secrete oil

Function of sweat glands : Function of sweat glands Secrete sweat

Epidermal layers : Epidermal layers

In what layers of the epidermis are the cells still alive? : In what layers of the epidermis are the cells still alive? Stratum spinosum Stratum basale

Bone Classification : Bone Classification Yellow bone marrow is found in the medullary cavity

Five functions of the skeletal system : Five functions of the skeletal system support protection movement storage hemopoiesis
