Associate with hair follicles and are found in the axillary and genital areas. Kind of sweat gland.

Ceruminous Glands

External auditory canal. Modified sweat gland secreting cerumen.

Conduction

Loss of heat energy as it is transferred from the warm body to cooler object.

Convection

Loss of heat to surrounding cooler air.

Cutaneous Membrane

Skin

Dermis

Thicker layer of the skin. Dense connective tissue under the epidermis.

Eccrine Gland

Type of sweat glands that secretes a watery substance. Important role in body temperature regulation.

Epidermis

Outer epithelial layer of the skin

Evaporation

Loss of heat as water changes from the liquid to vapor or gas state.

Integument

Natural covering like skin

Keratin

Protein found in skin, hair, and nails. Hardens cells and makes water resistant.

Stratum Germinativum

Innermost layer of the epidermis where cell division takes place

Subcutaneous Layer

Tissue beneath the dermis that contains fat cells

Sudoriferous Glands

Sweat glnda

Thermoregulation

Homeostatic regulation of body temperature by adjustments in the heat producing and heat losing mechanisms
