Question

What is the function of the hypodermis layer of skin?
A. Connects skin to bone and muscle.
B. Protects the body
C. Connect bone to muscle
D. Connect muscle to muscle

Answer 1

Hint: Three layers of skin are present in humans. First one and the outermost layer of the skin is the epidermis which creates the human's skin tone. It also provides a waterproof barrier. Dermis which is situated just below the epidermis is the second layer of skin. It includes hair follicles, connective tissue, and nerve endings. Third layer of the skin is considered to be subcutaneous tissue which is mostly fatty. This layer is located just under the first and second layer of the skin. An essential role is played by a third layer which involves the attachment of dermis to the body's bones and muscles. The hypodermis consists of vascularized, loose, areolar connective tissue and adipose tissue.

Complete answer:
The skin is the largest organ of our body and it keeps refreshing. It's ever-changing, and it contains many specialized cells and structures. The skin's primary function:
> Forms a protective barrier.
> Interacts with the hostile environment.
> Regulate body temperature.
< Gathers sensory information from the surrounding.
> Protect the body against diseases.
Layers of skin:
> Epidermis
> Dermis
> Hypodermis (Subcutaneous fat layer)

Epidermis	An outer thin layer of skin. Made up of 3 types of cells:1. Squamous cells- The layer formed by it sheds continuously and is called the stratum corneum. 2. Basal cells – located just below the squamous cells. 3. Melanocytes- They are found at the base of the epidermis and make melanin pigment that provides colour to the skin.
Dermis	The dermis makes the middle layer of the skin. The dermis contains the following:- Blood & Lymph vessels- Hair follicles- Sweat glands & Sebaceous glands- Collagen bundles & Fibroblasts- Nerves
Hypodermis	It is the deepest layer of skin. That consists of a network of collagen and fat cells. It conserves the body heat, acts as a shock absorber so protects the body from injury.

So, the correct answer is (B) Protects the body.

Note: Skin covers the body of an animal. Its main functions are: protection, regulation, and sensation. In mammals, the skin is an organ of the integumentary system made up of multiple layers of ectodermal tissue and guards the underlying organs. The skin interfaces with the environment form the first line of defence from pathogens. The thickness of the skin also varies from the location on an organism’s body. In humans, for example, the skin under the eyes is the thinnest & measures around 0.5 mm thick whereas the skin on the palms and the soles is the thickest skin of the body that measures about 4 mm thick.
