What is the function of Meissner’s corpuscles? They are touch receptors (mechanoreceptors). Located in dermal papillae of thick skin. Capsulated nerve ending formed of flat layers of Schwann cells and terminal branches of the afferent nerve.
Q. Which type of receptor detects pressure and vibration?
Pacinian receptors

Q. What is the function of Merkel discs?
The Merkel disc is a main type of tactile end organ for sensing gentle touch and is essential for sophisticated sensory tasks, including social interaction, environmental exploration, and tactile discrimination.
Q. What are the 2 main cells found in the epidermis?
The epidermis has three main types of cell:
- Keratinocytes (skin cells)
- Melanocytes (pigment-producing cells)
- Langerhans cells (immune cells).
Q. How does the epidermis protect the body?
What does the epidermis do? The primary function of the epidermis is to protect your body by keeping things that might be harmful out and keeping the things your body needs to function properly in. Bacteria, viruses and other infectious agents are kept out, helping prevent infections on your skin.
Q. What is the most common cell type in the epidermis?
Keratinocytes
Q. What is the most common cell type?
Red blood cells (RBCs) are by far the most abundant type of cell in the human body, accounting for over 80 percent of all cells. Adult humans have somewhere around 25 trillion RBCs in their body, on average.
Q. What are the 4 types of cells that make up the epidermis and their functions?
Cell types in the epidermis include keratinocytes that produce keratin and make up 90 percent of epidermal cells, melanocytes that produce melanin, Langerhans cells that fight pathogens in the skin, and Merkel cells that respond to light touch. The epidermis in most parts of the body consists of four distinct layers.
Q. What are the two main cells?
Cells are of two types: eukaryotic, which contain a nucleus, and prokaryotic, which do not. Prokaryotes are single-celled organisms, while eukaryotes can be either single-celled or multicellular.
Q. What structures are found in the dermis?
The dermis contains nerve endings, sweat glands and oil glands (sebaceous glands), hair follicles, and blood vessels. The nerve endings sense pain, touch, pressure, and temperature. Some areas of the skin contain more nerve endings than others.
