The major tissue types and their functions - ✔✔epithelial tissue covers
body surfaces; connective tissue supports other tissues structurally;
nervous tissue is responsible for rapid long-distance signalling,
coordination, and "thinking"; muscle tissue is specialized for movement by
means of cellular contraction
The major differences between tissues - ✔✔***SEE ATTACHED SHEETS***
The cell types and proteins that make tissues - ✔✔collagen is the most
abundant protein; actin, myosin,
The different layers of the skin and the associated terms - ✔✔The skin has
three layers—the epidermis, dermis, and fat layer (also called the
subcutaneous layer);

,The deepest layer of the epidermis, the stratum basale, is a single layer of
cells resting on a basement membrane (layer between the dermis and
epidermis), they divide continuously. As new cells form, older ones are
pushed toward the skin surface;
The next layer, the stratum spinosum, consists of spiny prickle cells that
interlock to support the skin;
The stratum granulosum, the thin middle layer, initiates keratinization
(production of keratin). This process starts the death of epithelial cells (the
cell type that makes up skin);
The stratum lucidum protects against sun ultraviolet-ray damage. This
thick layer appears only in frequently used areas such as palms of the
hands and soles of the feet;
The stratum corneum, the fifth, outermost layer is thick with rows of dead
cells. These cells contain soft keratin, which keeps the skin elastic and
protects underlying cells from drying out.

, Types of burns and how they are classified, including the rule of nines -
✔✔An adult who has been burned, the percent of the body involved can be
calculated as follows:
Head = 9%
Chest (front) = 9%
Abdomen (front) = 9%
Upper/mid/low back and buttocks = 18%
Each arm = 9% (front = 4.5%, back = 4.5%)
Groin = 1%
Each leg = 18% total (front = 9%, back = 9%)
The general steps in the inflammatory response in skin - ✔✔line of defense
triggered by penetration of the skin or mucous membranes, in which small
blood vessels in the vicinity of an injury dilate and become leakier,
enhancing the inflitration of leukocytes (white blood cells)
The parts of a long bone, the cells that are found and where, and the
protein in bone - ✔✔One of the types of tissue that makes up bone is the
