What are the 4 types of cells in the epidermis?
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.
What are the 4 types of cells that make up the epidermis and their functions quizlet?
Terms in this set (4)
- Keratinocytes. -most common. -they are or will become keratinized.
- Melanocytes. -found in deepest strata of epidermis. -produce and store melanin (dark pigment )
- Tactile Cells(Merkel Cells) -found in deepest strata of epidermis.

What type of cells make up the epidermis quizlet?
The epidermis is largely made of four cells. The keratinocytes, melanocytes, Merkel cells, and Langerhans cells. All four types are found in the deepest epidermal layer, the basal layer.
What are the primary cells of the epidermis quizlet?
Keratinocytes and melanocytes are the two main cell types in the epidermis. List the five layers, or strata, of the epidermis. Stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale are the five layers of the epidermis.
How many cells are in the epidermis?
The epidermis has three main types of cell: Keratinocytes (skin cells)…Keratinocytes.
| Layer | Cell type |
|---|---|
| Stratum spinulosum (spinous, spiny or prickle cell layer) | Intercellular bridges called desmosomes link the cells together. The cells become increasingly flattened as they move upward. |
What is found in the epidermis quizlet?
A new patient complains that she is not pregnant although she and her husband have been trying for six months.
What does the epidermis do quizlet?
Describe the function of the epidermis. The epidermis is made up of stratified squamous epithelial cells called keratinocytes. single layer of basal cells (cuboidal shaped stem cell which gives rise to keratinocytes. Merkel cells and melanocytes are dispersed through out this layer.
Which is a type of epidermal cell?
The epidermis has three main types of cell: Keratinocytes (skin cells) Melanocytes (pigment-producing cells) Langerhans cells (immune cells).
What are the types of cells in the epidermis and how are they related to each other quizlet?
What are the types of cells in the epidermis and how are they related to each other? (They are basal cells, squamous cells, and melanocytes. Basal cells divide and form the squamous cells, which reside in the layer above the basal cells. The basal layer contains the melanocytes.)
What are the two 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).
What are the 4 protective functions of skin?
Functions of the skin
- Provides a protective barrier against mechanical, thermal and physical injury and hazardous substances.
- Prevents loss of moisture.
- Reduces harmful effects of UV radiation.
- Acts as a sensory organ (touch, detects temperature).
- Helps regulate temperature.
- An immune organ to detect infections etc.
What cells would you most likely find in the dermis?
The dermis is a strong flexible connective tissue layer. Which of the following cell types are likely to be found in the dermis. Fibroblasts, macrophages, and mast cells. The dermis has two major layers; which of the following constitutes 80% of the dermis and is responsible for the tension lines in the skin.
What cell types are associated with the epidermis?
The epidermis contains no blood vessels, and is nourished by diffusion from the dermis. The main type of cells which make up the epidermis are keratinocytes, melanocytes, Langerhans cells and Merkel cells. The epidermis helps the skin to regulate body temperature.
What are the most abundant cells of the epidermis?
Langerhans cells, keratinocytes, melanocytes, and Merkel cells are all found in the epidermis. The Langerhans cell is a phagocyte. The keratinocyte is the most abundant cell in the epidermis. The melanocyte produces melanin, which is responsible for skin pigmentation.
What cell is only found in the epidermis?
A keratinocyte is the primary cell type (about 90%) within the epidermis which is the outermost layer of the skin. The alternate names for keratinocytes are basal cells since they are found in the basal layer (the stratum basale) of the skin.
