Melanin pigment of human skin is produced by

Options

A. Mast cells of corium
B. Melanocytes of corium and incorporated there
C. Melanocytes of corium and incorporated in epidermis
D. Melanocytes of epidermis.

Answer

**Step-by-Step Solution:**

1. **Identify the Pigment**: The question asks about the melanin pigment in human skin, which is responsible for skin pigmentation and complexion.

2. **Types of Melanin**: There are two main types of melanin:
- **Pheomelanin**: This type is lighter in color, ranging from red to yellow, and is typically found in individuals with a lighter complexion.
- **Eumelanin**: This type is darker, ranging from dark brown to black, and is found in individuals with a darker complexion.

3. **Source of Melanin Production**: Melanin is produced by specialized cells known as **melanocytes**. These cells are located in the skin.

4. **Location of Melanocytes**: Melanocytes are primarily found in the **epidermis**, which is the outermost layer of the skin. They are particularly active when the skin is exposed to sunlight.

5. **Process of Melanin Formation**: The process by which melanin is synthesized is called **melanogenesis**. This process occurs in response to UV exposure from the sun.

6. **Storage of Melanin**: The melanin produced by melanocytes is stored in small membrane-bound vesicles known as **melanosomes**.

7. **Incorporation into Skin**: While melanin is produced in the melanocytes, it is incorporated into the upper layer of the skin, specifically in the **epidermis**, where it contributes to the pigmentation of the skin.

8. **Conclusion**: Therefore, the correct answer to the question is that melanin pigment is produced by **melanocytes** in the skin.

**Final Answer**: Melanin pigment of human skin is produced by **melanocytes**.
