The dermis might be considered the “core” of the integumentary system (derma- = “skin”), as distinct from the epidermis (epi- = “upon” or “over”) and hypodermis (hypo- = “below”). Sensory receptors in the dermis include: free nerve endings, pacinian corpuscles, and hair follicle receptors The mechanoreceptors of the skin are the meissner's corpuscles (which respond to light touch), the pacinian corpuscles (deeper in the dermis and respond to pressure), and the merkel's disks (closely related to the merkel's cells located in the epidermis and respond to light touch).

Although skin has many layers, it can generally be divided into three main parts: The outer part (epidermis) contains skin cells, pigment, and proteins. We shall now examine these layers in more detail. Below the dermis is another connective tissue layer, the hypodermis, which is not part of the skin but is customarily studied in conjunction with it. Since the dermis contains collagen and elastin, it also helps support the structure of skin that we see.

The dermis provides nutrients to the epidermis. Beneath the dermis lies the hypodermis, which is composed mainly of loose connective and fatty tissues. The dermis comprises the bulk of the skin and provides its pliability, elasticity, and tensile strength. 1. The skin, the integumentary system’s organ, is composed of the epidermis (epithelial tissue) and dermis (connective tissues), with an underlying hypodermis that is technically not part of the skin organ.

The dermis is the thickest part of the skin and possibly the most important because it serves vital key roles. The greatest amount of sebum is secreted during puberty. The epidermis The epidermis is the most superficial layer of the skin. The sebaceous glands in the dermis secrete an oily substance called sebum.
