Dermis
Epithelial Cell
cell covering the surface of the skin and inner lining of body cavities and tubes
Gland Epithelium
surface lining cell, regenerative cell
Dense Connective Tissue
Connective tissue with large amounts of either collagen fibers (making them strong) or elastic fibers, or both. Dense tissues are typically strong (e.g. bone, cartilage, tendons, etc.)
Appocrine Sweat Glands
Odiferous sweat glands in axilla, pubic region and areola. Secretory and duct portion, both are coiled. Single layer of cuboidal to columnar secretory cells, surrounded by myoepithelial cells. ducts empty into hair follicles.
Arrector Pili Muscle
Tiny smooth involuntary muscle, attached to hair follicle and dermal papillae and cotracts when cold or frightened and produces goosebumps
Vein
a blood vessel that carries blood from the capillaries toward the heart
Artery
a blood vessel that carries blood from the heart to the body
Sebaceous Gland
a cutaneous gland that secretes sebum (usually into a hair follicle) for lubricating hair and skin
Dermal Papilla
a fingerlike projection of the papillary region of the dermis that may contain blood capillaries or Meissner corpuscles (of touch)
Follicle
a structure in the dermis of the skin from which a strand of hair grows
Lymphatic Vessel
a vascular duct that carries lymph which is eventually added to the venous blood circulation
Receptor
an organ having nerve endings (in the skin or viscera or eye or ear or nose or mouth) that respond to stimulation
Nerve
any bundle of nerve fibers running to various organs and tissues of the body
Sweat Gland
any of the glands in the skin that secrete perspiration
Subcutaneous Tissue
connective and adipose tissue layer just under the dermis
Reticular Layer
deeper layer of the dermis that supplies the skin with oxygen and nutrients; contains cells, vessels, glands, and follicles
Duct Epithelium
form cylinder that link secretory epithelium to surface
Ceruminous Glands
modified sweat glands, located in external ear canal, secretes cerumen (earwax)
Eccrine Sweat Glands
most numerous, important, and wide spread of the sweat glands, mostly on forehead, upper lip, palms and soles, not hair follicles, regulate temperature,
Papillary Layer
outer layer of the dermis, directly beneath the epidermis
Dermis
second layer of skin, holding blood vessels, nerve endings, sweat glands, and hair follicles
Sebum
the oily secretion of the sebaceous glands
Hair Shaft
the portion of the hair that projects beyond the skin
Hair Follicles
tube like pockets of epidermal cells that make hair cells and external keratin
