Which of the following best describes the order of skin layers from outermost to innermost?

Reviewed by Jordan Morley, Editorial Lead at 247SimpleTests. Written by the 247SimpleTests Editorial Team from the official source material cited on every question.

Correct answer

Epidermis, dermis, subcutaneous (hypodermis)

A Dermis, epidermis, subcutaneous
B Dermis, subcutaneous, epidermis
C Epidermis, dermis, subcutaneous (hypodermis)
D Subcutaneous, dermis, epidermis

Why this is the answer

From outermost to innermost, the skin layers are the epidermis (the outer protective layer you see), the dermis (the deeper living layer with blood vessels, nerves, glands, and follicles), and the subcutaneous layer, also called the hypodermis (the deepest layer of fatty tissue that insulates and cushions). Getting this order correct is fundamental skin anatomy. Many skin functions and service considerations depend on knowing which structures lie in which layer, so this ordering is a reliable exam fact.
