|
|
Basement membrane
|
glue like, holds and supports epthelial cells
|
|
Parital Portion
|
Serous membrane, that lines the walls of a body cavity
|
|
Visceral Portion

|
|
Pleura

Serous membrane in thoracic cavity
|
|
Peritoneum
|
Serous membrane in the abdominal cavity
|
|
Pleurisy
|
Thin watery fluid secreted by serous membranes, to reduce friction and serves as a lubrication for when organs rub against eachother.
|
|
Mucous Membrane
|
Epitheleal membranes that line body surfaces opening to the exterior.
Line respiratory, digestive, urinary, and reproductive tracts. |
|
Synovial
|
Membrane lining the spaces between bone and joints. They secrete thick and colorless lubricating fluid, called synovial.
|
|
Epidermis
|
Outer most layer of skin
|
|
Dermis
|
beneath epidermis, is thicker and made up of connective tissue
|
|
Subcutaneous
|
Thick layer of loose connective tissue and fat
|
|
Keratin
|
Protein substance, tough, water proof, provides outer layer of skin with a horny, abrasion-resistant, and protective quality
|
|

|
Brown pigment
|
|
Lanugo
|
Fine hair on newborn
|
|
Hair Papilla
|
Small cap shape clusters of cells, hair grows from
|
|
Arrector Pili
|
Tiny smooth muscle attached to the base of the dermal papilla above and to the side of the hair follicle below, contract when frightened or cold produces goose bumps
|
|
Meissner's Corpusal
Pacinian Corpusal |
The receptors in skin, allowing the body surface to act as a sensory organ
|
|
Free Nerve Ending

|
Most numerous of the skin glands, classified into two groups eccrine and apocrine
|
|
Eccrine sweat glands
|
Most numerous, important and wide spread sweat glands in body, distributed over total body surface, produce transparent watery liquid called perspiration

|
Sebaceous glands
|
Secrete oil for the hair and skin, they grow where hair grows. Their ducts open into hair follicles. Lubricate hair and skin
|
|
Functions of the skin
|
Protection
Temperature Regulation Sense organ activity |
|
Lesion
|
Any measurable variation from the normal structure of tissue, not necessarily signs of disease and do not constitute a disorder
|

Frequently used method to determine the extent of burn injury, body is divided into 11 areas of 9% each. Area around genitals = 1%
|
|
First degree burn
|
Causes minor discomfort and some redding of skin (sun burn)NO blistering occurs, tissue damage minimal
|
|
Second degree burn
|
Involves deep epidermal layers, and always causes injury to upper layers of dermis. Complete destruction dermis does not occur
|
|
Third degree burns
|
Complete destruction of epidermis and dermis, tissue death extends below primary skin layers into subcutaneous tissue. Involve muscle and bone
