The epithalamus, pineal gland, functions much like the limbic system by influencing the secretion of melatonin associated with circadian rhythms.
The spinalcord is perhaps the most simply arranged part of the CNS. Its basic structure, indicated in a schematic drawing of the eighth cervical segment, is the same at every level—a butterﬂy-shaped core of graymatter surrounded by whitematter. An often indistinct central canal in the middle of the...

nervous system consists of the brain, spinalcord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts. The brain and spinalcord form the control center known as the...

Central nervous system:
The CNS contains the brain and spinalcord. The PNS consists mainly of nerves, which are long fibers that connect the CNS to every other part of the body.
Peripheral nervous system:
The PNS includes motor...

lethal? As Baldomero Olivera discusses in the interview opening the unit (pp. 850–851), the answer is a mixture of molecules that disable neurons, the nerve cells that transfer information within the body. Because the venom almost instantaneously disrupts neuronal control of locomotion and respiration, an...

Abstract | The central nervous system (CNS) comprises the brain, spinalcord, optic nerves
and retina, and contains post-mitotic, delicate cells. As the rigid coverings of the CNS
