Integumentary System
Chapter 5 Anatomy & Physiology
Question | Answer |
---|---|
The skin and it appendages (Hair, nails, Skin glands) are collectively know as the | Integumentary System |
the outer most layer of the skin that consists of stratified squamous epithelial tissue, is called | Epidermis |
the inner deep layer of the skin that is composed of connective tissue, is called | Hypodermis |
Finger-like projects that extend upward from the dermis is called | Papillae |
Beneath the skin is a layer of subcutaneous tissue called the | Hypodermis |
this layer is also know as the stratum germinativum | Stratum Basale |
in the layers of the epidermis, the innermost layer is called | Stratum Basale |
in the layers of the epidermis, the outermost layer is called | Stratum Corneum |
new arriving flattened cells are called | Keratinocytes |
these replace the dead cells that flake away | Keratinocytes |
A tough, fibrous protein that replaces the cytoplasm and nucleus in each cell | Keratin |
scatter throughout the basal layer of the epidermis are cells called | Melanocytes |
melanocytes produce a substance that accumulates in the cells of the epidermis called | Melanin |
A reddish pigment is called | Pheomelanin |
Brown-Black pigment is called | Eumelanin |
A deficiency of oxygen in circulating blood, that result in you skin having a blue tint to it is called | Cyanosis |
Yellow discoloration to the skin and whites of the eyes is called | Jaundice |
a golden brown skin color | Bronzing |
extremely pale skin, white hair, and pink eyes | Albinism |
Abnormal redness of the skin | Erythema |
Pale skin | Pallor |
Bluish, black, or yellowish mark on the skin | Bruise |
part of the hair that extends above the skin is called the | Shaft |
each hair lies within a sheath of epidermis called a | Hair Follicle |
the lowest part of the hair where growth occurs | Hair bulb/root |
at the base of the hair is a cluster of connective tissue and blood vessels called the | Papilla |
excessive hair lose is called | Alopecia |
a type of hair lose that is mainly in men who have High levels of testosterone | Male Pattern Baldness |
the fold of skin that surround the nail body is called the | cuticle |
the visible part of the nail is called the | Nail Body |
the crescent shaped white area at the base of the nail is called the | Lunula |
the layer of epithelium under the nail is called | Nail bed |
the proximal end of the nail that's hidden underneath overlaying tissue is called the | Nail Root |
this gland is widespread throughout the body, but are especially abundant on the palms, soles, forehead, and upper torso. | Eccrine Glands |
this gland produces Sweat! | Eccrine Glands |
these glands open into the hair follicle and secretes an oily substance called sebum | Sebaceous Glands |
this helps keep hair and skin from drying out and becoming brittle | Sebum |
this gland is mainly located in the axillary and anogenital regions | Apocrine Glands |
these are scent glands that respond to stress and sexual stimulation | Apocrine Glands |
these glands are found in the ear canal | Ceruminous Glands |
the wax in our ears that we refer to as "ear Wax" is called | Cerumen |
