MICROANATOMY

Detailed explanation-1: -The integumentary system includes the epidermis, dermis, hypodermis, associated glands, hair, and nails. In addition to its barrier function, this system performs many intricate functions such as body temperature regulation, cell fluid maintenance, synthesis of Vitamin D, and detection of stimuli.

Detailed explanation-2: -The integumentary system functions in absorption (oxygen and some medications) and excretion (e.g., perspiration via the eccrine glands).

Detailed explanation-3: -The integumentary system helps regulate body temperature through its tight association with the sympathetic nervous system, the division of the nervous system involved in our fight-or-flight responses. The sympathetic nervous system is continuously monitoring body temperature and initiating appropriate motor responses.
