Skin

A good starting point is to identify the main layers (epidermis, dermis and hypodermis) of the skin at low magnification.

The three layers forming the skin can be identified in all skin sections.

The epithelium forming the surface layer, the epidermis, is usually the darkest layer visible. Sublayers are visible in the epidermis. Their staining varies - not just between stains but also between different H&E stained preparations (possibly depending on tissue preservation and how fresh the staining solutions were). At the transition from the epidermis to the dermis, staining will become lighter.

The lighter stained layer, the dermis, consists of dense irregular connective tissue. The dermis is much thicker than the epidermis. In thick skin, dermal papillae create a very irregular border between epidermis and dermis.

The hypodermis is the lightest layer visible and consists mainly of adipose tissue. Dense connective tissue strands may extend from the dermis deep into the hypodermis and anchor the skin to underlying structures.
