Your skin is the biggest and most seen part of your body. It does many important jobs, like keeping you safe from bad germs, keeping your body warm or cool, and feeling what is around you. First of all, your skin has three main parts: the epidermis, the dermis, and the subcutaneous tissue. As a result, each part has a different shape and job. In this article, we will discuss The Layers of Your Skin. Also known as The Epidermis, Dermis, and The Subcutaneous Tissue.
The Epidermis
Initially, the epidermis is the top part of your skin. Also, It has five smaller parts of cells that change all the time. The epidermis stops water from leaving your body and stops germs from getting in. Therefore, it also has melanin, a colour that makes your skin look the way it does and keeps you safe from sun rays.
The five smaller parts of the epidermis are:
- Stratum corneum: This is the top part of dead, flat cells that fall off every two weeks. Additionally, it helps your skin keep water and keep bad things out of your body.
- Stratum lucidum: However, this is a separate part only in the thick skin on your hands and feet.
- It lets the skin stretch, keeps it safe from rubbing, and makes it stops water from getting in or out.
- Stratum granulosum: This part has cells that are slowly dying and becoming more like the cells of the top parts. It also has fats that stop water from getting in or out.
- Stratum spinosum: This is the thickest part of the epidermis. It has new cells and cells that fight germs. Similarly, this is the main part that keeps bad things from getting into your body.
- Stratum basale: This is the bottom part of the epidermis. Such as, it has cells that make new cells, cells that make melanin, and cells that feel touch.
The Dermis
The dermis is the middle part of your skin. It is thicker than the epidermis and has many things that help your skin work and look good. The dermis has two parts: the papillary dermis and the reticular dermis.
After that, the papillary dermis is the thin, upper part of the dermis. It has:
- Blood vessels that bring air and food to the skin and take away waste
- Nerve endings that feel pain, heat, cold, pressure, and touch
- Lymph vessels that take away extra water and fight germs
- Hair follicles that make hair
- Sweat glands Furthermore, that make sweat cools your body and gegetsid of bad things.
- Sebaceous glands that make oil to keep your skin and hair smooth
- Meissner’s corpuscles feel light touch
- Pacinian corpuscles that feel shaking
Finally, the reticular dermis is the thick, lower part of the dermis. It has:
- Collagen fibre fibres make your skin strong and stretchy
- Elastin fibres that let your skin stretch and go back to normal
- Reticular fibres that hold together collagen and elastin
- Fibroblasts that make collagen, elastin, and reticular fibres
- Mast cells Similarly, you let out chemicals when you are hurt or allergic.
The Subcutaneous Tissue
The subcutaneous tissue is the deepest part of your skin. It is also called the hypodermis or subcutis. It mostly has fat cells called adipocytes that keep energy and keep your body warm or cool.
The subcutaneous tissue acts like a pillow that keeps your important organs safe from harm. Additionally, it also connects your skin to the muscles and bones below it.
Summary
Your skin is a complex part of your body that has three main parts: the epidermis, the dermis, and the subcutaneous tissue. So, each part has a different shape and job that help you stay well.
