What does nerve cells look like?
Neurons are of three types (shapes)
Unipolar: they have a cell body (soma) and a single process (axon and a dentrite)
Bipolar: they have a cell body and an axon and a dentrite on opposite poles.
Multipolar:they have a cell body, axon and more than two dentrites.
No, it's a cell of the immune system. They are a subset of dendritic cells found in the epidermis, that capture antigens (with the long arms that make them look like nerves) and take them to lymph nodes to present to T cells. Paul Langerhans (who discovered them) in 1968 actually thought they were nerve cells!
