Follicle

Accessory organ of the skin that is found in the dermis and the sites at which hairs emerge

Basal cell carcinoma

Accounts for 90% of all skin cancer in the US and is the slowest and less likely type of cancer to spread

Hemoglobin

Carries oxygen in red blood cells

Herpes zoster

Caused by the varicella virus, this is responsible for causing chickenpox and shingles.

Melanocyte

Cell type within the epidermis that makes the pigment melanin

Which of the following is a characteristic of the dermis?

It contains epithelial, connective, muscle, and nervous tissues.

Layer beneath each nail

Squamous cell carcinoma

Less common than basal cell carcinoma but more likely to spread to surrounding tissues; most likely sites affected are the lips, face, ears, and backs of hands

Dermis

Middle of the skin, which contains connective tissue, nerve endings, hair follicles, sweat glands, and oil glands

Malignant melanoma

Most aggressive type of skin cancer; its incidence is growing

Eccrine gland

Most numerous type of sweat gland; they produce a watery type of sweat and are activated primarily by heat

Epidermis

Most superficial layer of the skin

Sebum

Oily substance produced by sebaceous glands

Melanin

Pigment deposited throughout the layers of the epidermis

Petechiae

Pinpoint skin hemorrhages resulting from a bleeding disorder; vascular

Purpura

Purple-red bruise, usually the result of clotting abnormalities; vascular

Which of the following is NOT a form of skin cancer?

Subcutaneous

Hypodermis

Subcutaneous layer of the skin that is largely made of adipose tissue

Which of the following is NOT a layer of the skin?

Sudoriferous

Tumor

Swelling of abnormal tissue growth; primary

Herpes simplex

The most common types are 1 (occurring above the waist) and 2 (occurring below the waist).

Folliculitis

This condition is commonly known as "swimmers rash," and inflammation of the hair follicles is a classic sign.

Keratin

Tough, hard protein contained in skin, hair, and nails

Cyanosis

Turns the skin a bluish color due to a lack of oxygen

Ulcer

Wound resulting from tissue loss; secondary

The ______ muscles are responsible for "the hair on the back of your neck to stand up" (become erect) when a person is cold or, nervous or "gets a creepy" feeling.

arrector pili

Injured skin is inflamed and looks red because the nearby blood vessels

dilate

epidermis

The stratum corneum is the most superficial of the 2 layers of the ______, and it consists of dead, flat cells.

epidermis

Inflamed skin is often painful because the excess ______ activates pain receptors.

fluid

Which accessory organ of the skin, located in the dermis below the shaft, is the site at which a hair emerges?

follicle

Benign tumors of the blood vessels are also known as

hemangiomas.

The ______ is the third layer of skin and is connected to the epidermis via the dermis.

hypodermis

Vasodilation of the blood vessels in the skin

increases heat loss.

The more ______ in skin, the darker it is.

melanin

The ______ holds the nail to the underlying skin and provides it with nutrients.

nail bed

severity

Which of the following is the external covering of the body and the largest multifunctional organ of the integumentary system?

skin

Sudoriferous glands are

sweat glands.

During exercise, the muscles contract, creating a rise in body temperature, which leads to

vasodilation.

-Arrector pili muscles -Hair follicles -Sweat glands -Collagen fibers -Sebaceous glands

Which of the following are layers of the skin?

-Hypodermis -Dermis -Epidermis

Which of the following statements are true regarding the sudoriferous glands?

-The majority of the sudoriferous glands are located in the dermis. -Apocrine glands are most concentrated in areas of skin with coarse hair, such as the armpit and groin. -Apocrine glands produce a thick, protein-based sweat. -Eccrine glands are most numerous of the 2 types. -The two types of sweat glands are eccrine and apocrine.

The integumentary system consists of skin and accessory organs which are:

-sebaceous glands -hair follicles -sudoriferous glands -nails
