Which of the following cell is known as 1st cousin of melanocyte:
**Core Concept**
The question is testing the student's knowledge of melanocyte biology and the related cell types in the skin. Melanocytes are pigment-producing cells responsible for skin and hair color. They originate from neural crest cells during embryonic development.
**Why the Correct Answer is Right**
The correct answer is the cell type that is closely related to melanocytes in terms of cell lineage and function. Melanocytes are derived from the neural crest cells, which also give rise to other cell types such as Schwann cells and Merkel cells. Among the options, one cell type is known to be closely related to melanocytes in terms of embryonic origin and function.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is not directly related to melanocyte biology.
**Option B:** This option is incorrect because it is a different type of skin cell with a distinct function.
**Option C:** This option is incorrect because it is not a cell type that is closely related to melanocytes in terms of embryonic origin or function.
**Clinical Pearl / High-Yield Fact**
Merkel cells, which are the correct answer, are involved in mechanoreception and are found in the epidermis, particularly in areas with high sensory innervation, such as the fingertips. They play a crucial role in tactile sensation and are often associated with melanocytes in terms of their embryonic origin.
**Correct Answer: C. Merkel cells.**
