What are the 6 main structures of the skin?
What are the 6 main structures of the skin?
The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
What are the 6 general functions of the skin?
The skin is broken up into 3 different layers, the epidermis or top layer, dermis, and subcutaneous layer. Each of these layers performs important roles in keeping our body healthy. The skin performs six primary functions which include, protection, absorption, excretion, secretion, regulation and sensation.
What is the structure of the skin?
The skin consists of two layers: the epidermis and the dermis. Beneath the dermis lies the hypodermis or subcutaneous fatty tissue. The skin has three main functions: protection, regulation and sensation. Wounding affects all the functions of the skin.
What are the 5 structures of the skin?
The epidermis of thick skin has five layers: stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.

What are the 4 appendages of the skin?
The skin appendages include sweat glands, nails, and the pilosebaceous unit of the skin, comprised of the hair shaft, hair follicle, sebaceous gland, and arrector pili muscle — these appendages derive from a down growth of the epidermis beginning in the third month of fetal life.
What are the 7 functions of the skin?

What are the 3 accessory structures of the skin?
Accessory structures of the skin include the hair, nails, sweat glands and sebaceous glands. These structures embryologically originate from the epidermis and are often termed “appendages”; they can extend down through the dermis into the hypodermis.
What is the 7 functions of the skin?
Functions of the skin Storing lipids (fats) and water. Creating sensation through nerve endings that detect temperature, pressure, vibration, touch, and injury. Controlling water loss by preventing water from escaping by evaporation. Providing water resistance by preventing nutrients from being washed from the skin.
What are the 4 main structures of the integumentary system?
The integumentary system includes the epidermis, dermis, hypodermis, associated glands, hair, and nails.
How are the five layers of the skin related?
The cells (three to five layers deep) become flatter, their cell membranes thicken, and they generate large amounts of the proteins keratin, which is fibrous, and keratohyalin, which accumulates as lamellar granules within the cells (see Figure 5.5 ).
How is the skin part of the integumentary system?
The skin and its accessory structures make up the integumentary system, which provides the body with overall protection. The skin is made of multiple layers of cells and tissues, which are held to underlying structures by connective tissue (Figure 5.2). The deeper layer of skin is well vascularized (has numerous blood vessels).
What makes up the two basic tissues of the skin?
Complete the following statements by writing the appropriate word or phrase on the correspondingly numbered blank: The two basic tissues of which the skin is composed are dense connective tissue, which makes up the dermis, and which forms the epidermis. Most cells of the epidermis are 2 The protein makes the dermis tough and leatherlike.
What are the functions of the skin in the body?
Skin functions as the body’s first line of defence against bacteria and viruses, and is also a vital sensory organ, sensitive to the softest touch as well as pain. Healthy skin also maintains the balance of fluids and helps to regular body temperature.
