What is the relationship between what affects the thickness

What is the relationship between what affects the thickness of the skin and thickness of the hypodermis?

Solution

Answer:

Stratum corneum is the layer that affects mostly the thickness of skin with dermis & epidermis. The epidermis & dermis thickness of skin is going to provide protection & strength to the skin in the integumentary system

The three layers of skin are,

1). Epidermis; 2 . Dermis; 3. Hypodermis

Epidermis & dermis of the skin is the outermost layers of the skin made of keratinized stratified squamous epithelial tissue in which outer or apical surface cells are hardened or dead. It does not contain blood vessels (not vascularized), and the dermal layer supplies oxygen and nutrients by means of diffusion. The layer of the epidermis that contains transulacent cells filled keratin are often referred as “thick stratum lucidum”. The other layers often sloughed off from the surface composed of dead cells that are flat and filled with keratin often referred as “stratum corneum”

The layer of skin arranged in between the epidermis and hypodermis (subcutaneous tissue) known as dermis & the thickness of these layers related based on adipose connective tissue (present in hypodermis but absent in epidermis & dermis outer layers of skin). Dermis contains the roots of hair cells, sweat glands, sebaceous glands, blood vessels and receptors of mechanical stimuli but these structures are not related to hypodermis of skin & do not cause any thickness of hypodermis. The dermis of skin of two regions,

1). Papillary region (made of loose areolar connective tissue)

2). Reticular region (made of dense irregular connective tissue)

The major function of dermis is to cushion the body from mechanical stress and provide elastic nature to the skin, the presence of sensory receptors also provide the sense of touch and heat.

Hypodermis is the connective tissue present beneath the skin and is made of adipose and areolar (loose connective tissue). This layer insulate the body to prevent the loss of heat an also act as an energy reservoir in the form of adipose tissue. Skin, in association with its accessory structures and subcutaneous tissue or hypodermis consists of the “integumentary system.” This system protects the internal organs from the external environment and hazards. This system also helps to maintain the body temperature by resisting loss of temperature. The accessory structure of skin includes the receptors, glands, hair on the surface layers. The integumentary system enables synthesizing vitamin D from natural sunrays and using adipose tissue in hypodermis that imparts \"thickness\" of the skin finally promotes thermoregulation & hydroregulation.
