Which of the following are accessory organs of the integumentary system?

The accessory organs of the integumentary system include hair, nails, and nerve receptors. These components play essential roles in the overall function and health of the skin. Hair contributes to protection, sensation, and thermoregulation, while nails protect the distal phalanxes and enhance fine touch sensation. Additionally, nerve receptors are crucial for detecting various stimuli such as pressure, pain, and temperature, allowing the body to respond accordingly to environmental changes.

The other options, while they contain important structures, do not belong to the integumentary system. Muscles, bones, and arteries are part of the musculoskeletal and circulatory systems, while glands can be a part of the integumentary system, the mention of lymph nodes and blood vessels indicates a role in the immune and circulatory systems, respectively. Cartilage, tendons, and ligaments primarily relate to connective tissues, further distancing them from the accessory organs of the integumentary system.
