The nervous system of the body is split into two parts: the central nervous system (CNS) and the peripheral nervous system (PNS). In situ hybridization on sections from the adult rat peripheral and central nervous systems demonstrated that trkB mRNA was expressed not only by neurons but also by cells in central nervous system white matter as well as by Schwann cells in the sciatic nerve. The CNS is composed of three principal structures: the brain, brainstem and spinal cord. Lumbar puncture (spinal tap) is a procedure by which cerebrospinal fluid is removed through a medium-sized needle, usually at the L3-4 interspace, in order to examine the presence of cells, proteins, glucose, or infection. The peripheral nervous system (PNS) is one of the two major components of the body's nervous system. Lumbar puncture (spinal tap) is a procedure by which cerebrospinal fluid is removed through a medium-sized needle, usually at the L3-4 interspace, in order to examine the presence of cells, proteins, glucose, or infection.
