What is the integumentary system?
the covering of the body, includes hair, glands, and nails
what is the largest organ of the body?
the skin
what are the two layers of the skin?
inner layer= dermis outer layer= epidermis
what is under the dermis but not a part of the skin?
subcutaneous layer
What does the epidermis consist of? what type of tissue is it?
consists of epithelial cells, melanocytes, and keratinocytes, tissue type is epithelial tissue
what is the function of the epidermis?
covers the body and lines the body cavities
What are melanocytes responsible for?
skin color, they produce melanin, more melanin = darker skin
what are keratinocytes responsible for?
producing keratin, makes epithelial cells tough, waterproof, and resistant to bacteria
what does the basal cell layer of epithelium do?
epithelial cells are constantly being produced and pushing the older cells to more superficial layers where they die and are filled with keratin (keratinization)
what is the superficial layer of the epidermis called?
stratum corneum
What is the dermis?
thick area of connective tissue containing hair follicles, blood vessels, nerves and glands
What does the dermis do?
supplies nutrients for the skin, thermoregulation, sense of touch, glands secrete substances necessary for skin maintenance and function
what are the four types of cells in the dermis? What are there functions?
fibroblasts (produce collagen and elastin to make skin tough and durable, elastin makes things stretch and recoil), macrophages (engulf bacteria and harmful foreign substances), mast cells (produce histamine), plasma cells (produce antibodies)
What is the most abundant protein in the body? Where is it found?
collagen, found in bones, tendons, cartilage, and skin
what is subcutaneous tissue?
layer of CT, not part of the skin, connects dermis to muscles and organs below it, and provides insulation
whats is a hair follicle?
epidermal cells at the base of a tube like depression that hair grows from
what is the hair papilla?
indentation at the bottom of the bulb, contains blood vessels to nourish hair and to promote growth
eponychium?
nail cuticle, overlaps the nail
sebaceous glands?
secrete an oil called sebum which keeps the skin soft and water proof, it also keeps the hair pliable and prevents it from becoming too brittle and breaking
sudoriferous glands?
sweat glands, play a role in thermoregulation by secreting sweat onto the surface of the skin,
ceruminous glands?
produe cerumen (ear wax), helps prevent bacterial infection
