Some stay in the marrow and develop into B lymphocytes (B cells); others travel to the thymus and become T lymphocytes (T cells). These two cell types have different roles.

Axons send impulses away from the soma and dendrites carry incoming information. Neurons are most easily identified by their axons in either longitudinal or cross-sectional slide. Groups of neurons are referred to as ganglia in the peripheral nervous system and as nuclei in the central nervous system. Chen, T., Bakhshi, H., Liu, L., Ji, J. & Agarwal, S.
