The Integumentary System: Components

Which structures are considered appendages of the skin within the integumentary system?

• Only hair and nails

• Oil glands, hair, sweat glands, and nails

• Only sweat glands and oil glands

• Only hair follicles

Which labeled structure in the skin diagram produces perspiration for thermoregulation?

• Hair shaft

• Oil gland

• Sweat gland

• Epidermis

What is the superficial layer of the skin called?

• Dermis

• Hypodermis

• Epidermis

• Basement membrane

Which statement best describes the composition of the epidermis?

• It is made of muscle fibers.

• It is made of epithelial cells.

• It is made of nervous tissue.

• It is made of adipose tissue.

Why is the epidermis described as avascular?

• It lacks sweat glands.

• It contains only blood capillaries.

• It contains no blood vessels.

• It has only lymphatic vessels.

A student observes that the outermost protective layer of the body is damaged in a minor scrape. Which skin layer is primarily affected?

• Dermis

• Epidermis

• Hypodermis

• Subcutaneous fat

Which pairing correctly matches a skin component with its classification in the integumentary system?

• Nails — skin layer

• Hair — appendage

• Epidermis — appendage

• Sweat gland — skin layer

Which statement best describes the dermis based on the diagram and notes?

• It is the outermost avascular layer of the skin made of epithelial tissue.

• It is the deeper layer that makes up most of the skin and is vascular connective tissue.

• It is not part of the skin and consists primarily of adipose tissue.

• It is a thin layer located superficial to the epidermis and contains no blood vessels.

Which tissue type primarily composes the subcutaneous tissue (hypodermis)?

• Connective tissue rich in collagen fibers

• Epithelial tissue forming stratified layers

• Adipose tissue located deep to the skin

• Muscle tissue with contractile fibers

A student claims the subcutaneous tissue is part of the skin. Based on the material, how should you respond?

• Agree; it is the superficial layer of the skin.

• Disagree; it is not part of the skin and lies deep to it.

• Agree; it is the upper portion of the dermis.

• Disagree; it is part of the epidermis only.
