  • What are the main functions of the integumentary system?

    The integumentary system protects the body, regulates temperature, prevents water loss, and provides sensory information.

  • What are the three primary layers of the skin?

    The epidermis, dermis, and hypodermis (subcutaneous layer).

  • What type of tissue primarily composes the epidermis?

    Keratinized stratified squamous epithelium.

  • What is the role of keratin in the skin?

    Keratin provides strength and waterproofing to the skin.

  • Name the cells responsible for producing melanin.

    Melanocytes produce melanin, the pigment that protects against UV radiation.

  • What is the function of Langerhans cells in the epidermis?

    Langerhans cells act as immune cells that detect pathogens.

  • Which layer of the skin contains blood vessels and nerves?

    The dermis contains blood vessels, nerves, hair follicles, and glands.

  • What are the two layers of the dermis?

    The papillary layer (superficial) and the reticular layer (deep).

  • What type of connective tissue is found in the dermis?

    Dense irregular connective tissue predominates in the dermis.

  • What is the hypodermis composed of?

    The hypodermis is mainly composed of loose connective tissue and adipose tissue.

  • What is the primary function of the hypodermis?

    It provides insulation, cushioning, and energy storage.

  • Name the two types of sweat glands in the skin.

    Eccrine glands (thermoregulation) and apocrine glands (associated with hair follicles).

  • What is the function of sebaceous glands?

    Sebaceous glands secrete sebum to lubricate and waterproof the skin and hair.

  • What is the role of hair in the integumentary system?

    Hair provides protection, sensory input, and helps regulate body temperature.

  • What is the structure of a hair follicle?

    A hair follicle is a tubular invagination of the epidermis that surrounds the hair root.

  • What is the function of nails?

    Nails protect the distal phalanges and enhance fine touch and manipulation.

  • How does the skin contribute to thermoregulation?

    Through sweat secretion and blood vessel dilation or constriction in the dermis.

  • What pigment determines skin color?

    Melanin is the primary pigment determining skin color.

  • What is the process of keratinization?

    Keratinization is the formation of a tough, protective layer of dead skin cells filled with keratin.

  • Which layer of the epidermis is the outermost?

    The stratum corneum is the outermost layer of the epidermis.
