Ch 4 . Integumentary System Flashcards
Outer layer of the skin
Epidermis
Inner layer of the skin
Dermis
Oil glands that usually open onto hair follicles
Sebaceous glands
Glands that produce sweat ; found over most of the body
Eccrine glands
The small organs that produce hair
Hair follicles
Tiny muscle fibers attached to hair follicles that cause the hair to stand erect
Arrector pili
Any of the fine threadlike strands growing from the skin of humans
Hair
Deepest section of the skin , made of adipose tissue
Hypodermis
Opening in the skin for sweat
Sweat pore
Include the cutaneous mucous and serous membranes
Epithelial membranes
This composes your skin and is a dry membrane
Cutaneous membrane
Membrane that secretes mucous that lubricates the surface of organs and keeps them moist. lines open body cavities
Mucous membrane
The membrane that lines close cavities within the bodies are called
Serous membranes
What type of membrane forms the inner lining of joint cavities and secrete a thick fluid?
Synovial membrane
Double folded membrane surrounding the abdominal cavity
Perineum
Membrane surrounding the lungs
Pleura
A double layer of membrane surrounding the heart
Pericardium
Consist of the skin, mucous membranes, hair and nail
Integumentary system
Layer found underneath the dermal layer
Subcutaneous tissue known as hypodermis
In epidermal cell that produces keratin
Keratinocytes
Deepest layer of the epidermis
Stratum básale
A layer of the epidermis that provides strength and flexibility to the skin
Stratum spinosum
3 to 5 layers of cells that have begun to lose their nuclei .they give skin its color
Stratum granulosum
A layer of the epidermis found only in the thick skin of the fingers, palms and soles of feet
Stratum lucidum
The most superficial layer of the epidermis consisting of dead cells
Stratham corneum
A pigment that gives skin its color
Melanin
Cells an epidermis that help activate immune system
Epidermal dentritic cells
Touch receptors in the skin
Merkel cells
Superficial layer of the dermis made of loose, areolar connective tissue
Papillary layer
The layer of skin superficial to the papillary layer, deepest skin layer
Reticular layer
Include nails, sweat, glands, sebaceous oil glands, and hair, follicles, and hair
Skin appendages
The part of a hair that is embedded in the hair follicle
Hair root
Malignant tumor of a squamous epithelial cells in the epidermis
Squamous cell carcinoma
Cancerous growth compose of melanocytes
Malignant melanoma
Malignant tumor of the basal cell layer of the epidermis
Basal cell carcinoma
Secrete chemical substance into ducks that lead either to other organs or out of the body
Exocrine glands
Oily substance secreted by sebaceous glands
Sebum
Sweat glands
Sudoriferous glands
Attached to the hair follicles and are found under the armpit genital area. They begin to function during puberty.
Apocrine glands
A burn in which only the outer layer part of the skin is burned and turns red
First-degree burn
Partial thickness burn blisters damage to the epidermis and dermis
Second-degree burn
A very serious burn in which deepest layers of skin and nerves ending are damage
Third-degree burn
