Subcutaneous tissue

subcutaneoussubcutaneous fathypodermis
The dermis or corium is a layer of skin between the epidermis (with which it makes up the cutis) and subcutaneous tissues, that primarily consists of dense irregular connective tissue and cushions the body from stress and strain.
The hypodermis is derived from the mesoderm, but unlike the dermis, it is not derived from the dermatome region of the mesoderm.

Cutis (anatomy)

cutiscutaneousdermal layer
The dermis or corium is a layer of skin between the epidermis (with which it makes up the cutis) and subcutaneous tissues, that primarily consists of dense irregular connective tissue and cushions the body from stress and strain.
Cutis is the combined term for the epidermis and the dermis, the two outer layers of the skin.

Dense irregular connective tissue

The dermis or corium is a layer of skin between the epidermis (with which it makes up the cutis) and subcutaneous tissues, that primarily consists of dense irregular connective tissue and cushions the body from stress and strain.
This type of connective tissue is found mostly in the reticular layer (or deep layer) of the dermis.

Sweat gland

sweat glandsporesweat
In addition, hair follicles, sweat glands, sebaceous glands (oil glands), apocrine glands, lymphatic vessels, nerves and blood vessels are present in the dermis. Within the reticular region are the roots of the hair, sebaceous glands, sweat glands, receptors, nails, and blood vessels.
The secretory coil or base, is set deep in the lower dermis and hypodermis, and the entire gland is surrounded by adipose tissue.

Somatosensory system

touchtactilesomatosensory
It also contains mechanoreceptors that provide the sense of touch and thermoreceptors that provide the sense of heat.
They are located in the dermal papillae; due to their reactivity, they are primarily located in fingertips and lips.

Basement membrane

basement membranesbasement membrane zonecapillary basement membranes
The dermis is tightly connected to the epidermis through a basement membrane.
The primary function of the basement membrane is to anchor down the epithelium to its loose connective tissue (the dermis) underneath.

Hair

Within the reticular region are the roots of the hair, sebaceous glands, sweat glands, receptors, nails, and blood vessels.
Hair is a protein filament that grows from follicles found in the dermis.

Cutaneous receptor

Within the reticular region are the roots of the hair, sebaceous glands, sweat glands, receptors, nails, and blood vessels.
The cutaneous receptors' are the types of sensory receptor found in the dermis or epidermis.

Fingerprint

At the surface of the skin in hands and feet, they appear as epidermal or papillary ridges (colloquially known as fingerprints).
A fingerprint is an impression left by the friction ridges of a human finger.

Nail (anatomy)

nailnailsfingernail
Within the reticular region are the roots of the hair, sebaceous glands, sweat glands, receptors, nails, and blood vessels.
Like all skin, it is made of two types of tissues: the deeper dermis, the living tissue which includes capillaries and glands, and the epidermis, the layer just beneath the nail plate, which moves toward the finger tip with the plate.

Hair follicle

hair folliclesfolliclefollicles
In addition, hair follicles, sweat glands, sebaceous glands (oil glands), apocrine glands, lymphatic vessels, nerves and blood vessels are present in the dermis.
It resides in the dermal layer of the skin and is made up of 20 different cell types, each with distinct functions.

Langer's lines

Langer linestension lines
The orientation of collagen fibers within the reticular dermis creates lines of tension called Langer's lines, which are of some relevance in surgery and wound healing.
They correspond to the natural orientation of collagen fibers in the dermis, and are generally perpendicular to the orientation of the underlying muscle fibers.

The skin weighs an average of four kilograms, covers an area of two square meters, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue.

Epidermis

epidermalepidermal cellsepidermal layer
The dermis or corium is a layer of skin between the epidermis (with which it makes up the cutis) and subcutaneous tissues, that primarily consists of dense irregular connective tissue and cushions the body from stress and strain.
The epidermis is the outermost of the three layers that make up the skin, the inner layers being the dermis and hypodermis.

Tactile corpuscle

Meissner's corpuscleMeissner's corpusclesMeissner corpuscle end-organ
This is named for its fingerlike projections called papillae, that extend toward the epidermis and contain either terminal networks of blood capillaries or tactile Meissner's corpuscles.
More specifically, they are primarily located in glabrous skin just beneath the epidermis within the dermal papillae.

Skin

The dermis or corium is a layer of skin between the epidermis (with which it makes up the cutis) and subcutaneous tissues, that primarily consists of dense irregular connective tissue and cushions the body from stress and strain.
The epidermis contains no blood vessels, and cells in the deepest layers are nourished by diffusion from blood capillaries extending to the upper layers of the dermis.

Rete pegs

It intertwines with the rete ridges of the epidermis and is composed of fine and loosely arranged collagen fibers.
Also known as papillae, they are downward thickenings of the epidermis between the dermal papillae.

Elastic fiber

Structural components of the dermis are collagen, elastic fibers, and extrafibrillar matrix.
