The cranial region includes the upper part of the head while the; facial region includes the lower half of the head beginning below the ears. The forehead is referred to as the frontal region. The eyes are referred to as the orbital or ocular region. The cheeks are referred to as the buccal region. The ears are referred to as the auricle or ...
The human stratum corneum comprises several levels of flattened corneocytes that are divided into two layers: the stratum disjunctum and stratum compactum. The skin's protective acid mantle and lipid barrier sit on top of the stratum disjunctum. [5] The stratum disjunctum is the uppermost and loosest layer of skin.
Estimates place the number of individual bacteria on the surface of human skin at 7.8 million per square centimetre (50 million per square inch), though this figure varies greatly over the average 1.9 square metres (20 sq ft) of human skin. Oily surfaces, such as the face, may contain over 78 million bacteria per square centimetre (500 million ...
Surface anatomy, or superficial anatomy, is important in human anatomy being the study of anatomical landmarks that can be readily identified from the contours or other reference points on the surface of the body. [1] With knowledge of superficial anatomy, physicians gauge the position and anatomy of deeper structures.
The front of the human head is called the face. It includes several distinct areas, [3] of which the main features are: The forehead, comprising the skin beneath the hairline, bordered laterally by the temples and inferiorly by eyebrows and ears; The eyes, sitting in the orbit and protected by eyelids and eyelashes
The epidermis is the outermost of the three layers that comprise the skin, the inner layers being the dermis and hypodermis. [1] The epidermal layer provides a barrier to infection from environmental pathogens [2] and regulates the amount of water released from the body into the atmosphere through transepidermal water loss.

The skin is one of the largest organs of the body. In humans, it accounts for about 12 to 15 percent of total body weight and covers 1.5 to 2 m 2 of surface area. [1] 3D still showing human integumentary system. The skin (integument) is a composite organ, made up of at least two major layers of tissue: the epidermis and the dermis. [2]
