Integumentary System and Body Temperature

This set of flashcards covers key terms and concepts related to the integumentary system and body temperature from the lecture notes.

Epidermis

The outermost layer of skin, consisting of multiple layers, including the stratum germinativum and stratum corneum.

Dermis

The layer of skin beneath the epidermis that contains connective tissue, hair follicles, and glands.

Stratum germinativum

The deepest layer of the epidermis responsible for generating new skin cells.

Stratum corneum

The outermost layer of the epidermis composed of dead cells that provide a protective barrier.

Thermoregulation

The process by which the body maintains its normal temperature through mechanisms such as sweating and blood vessel dilation.

Insensible perspiration

The loss of water from the body through the skin that is not perceived by the individual.

Sensible perspiration

Visible sweating that helps cool the body through evaporation.

Melanin

A dark pigment produced by melanocytes in the skin, which contributes to skin color.

Carotene

A yellow pigment found in the skin that can influence skin color but is often overshadowed by melanin.

Hypothermia

A condition that occurs when body temperature drops below the normal range, leading to potentially dangerous symptoms.

Hyperthermia

A condition that occurs when body temperature rises significantly above normal, potentially leading to heat-related illnesses.

Sebaceous gland

A gland in the skin responsible for secreting oil to lubricate the skin and hair.

Sweat gland

A gland that produces perspiration, which helps cool the body.

Body temperature range

The normal body temperature varies from 97°F to 100°F, with an average of 98.6°F.

First-degree burn

A simple burn affecting only the epidermis, causing redness and pain.

Second-degree burn

A burn that affects both the epidermis and part of the dermis, causing blisters.

Third-degree burn

A severe burn that destroys the epidermis and dermis, affecting deeper tissues.

Rule of nines

A method for estimating the total body surface area affected by burns, useful in burn treatment.
