Epidermis - 4 Layers
Back
Dermis
The dermis is the layer of skin that lies beneath the epidermis and above the subcutaneous layer. It is the thickest layer of the skin, and is made up of fibrous and elastic tissue. Thus, it provides strength and flexibility to the skin.
Back
Hypodermis
The hypodermis, also known as the subcutaneous tissue, is located beneath the dermis. It primarily consists of adipose (fat) tissue, which serves multiple roles such as thermal insulation, energy storage, and cushioning against mechanical impact.

DEFINITION
The integumentary system is the set of organs forming the outermost layer of an animal's body.
Info
Stratum Spinusom
Objectives
Describe the skin, its parts and function.
DEFINITION
Stratum Corneum
Pili Arrector Muscle
It is attached to each hair follicle, for erecting the hair.
Pili Arrector Muscle
Situations such as extreme emotions or extreme temperatures can activate its involuntary contraction , resulting in hair erection or skin wrinkling.
Nail
HAIR
Hair Shaft
Hair Root
Did you know
Nail
Fingernails and toenails are hard plates made of a tough protein called keratin.
An area called the nail matrix adds keratinized cells to the nail root, and the whole nail is continuously pushed forward along the nail bed towards its free edge.
Info
Sebaceous Gland
Stratum Lucidum
The skin forms a protective barrier between the external environment and the internal organs.
Stratum Corneum
This is the outermost layer, It's made up of old, flat skin cells that are no longer alive. These cells act like a shield, protecting your body from outside things like germs and dirt.
Stratum Basale
Melanin
Stratum Granulosum
This layer is where skin cells start changing and producing a substance called keratin.
KErATIN
Stratum Granulosum
KErATIN
Stratum Spinusom
The cells in this layer look a bit spiky under a microscope. These spiky cells are busy making more keratin that helps to form a waterproof barrier that functions to prevent fluid loss from the body.
Sudoriferous Gland
Referred to as "sweat gland" where it is a long tubule coiled in the dermis layer, and uses a long duct to release sweat onto skin surface through a pore.
Sudoriferous Gland
Info
Stratum Basale
This is where all the new skin cells are born. It is responsible for constant cellular renewal and contains melanocytes, which synthesize melanin.
Melanin
Stratum Lucidum
This layer is clear and helps make those areas of your skin tougher and able to handle pressure.

Objectives

HAIR
Hair Shaft
It consists of two regions, hair shaft and hair root. It is made of keratinized cells produced by the epithelial cells.

Info
Sebaceous Gland
Sebaceous glands are exocrine glands that have the responsibility of producing and releasing sebum onto the surface of the skin to help moisturize the skin and hair.
