CHAPTER 28 Nervous Systems

CHAPTER 28 Nervous Systems. Can an Injured Spinal Cord Be Fixed?. The spinal cord is the central communication conduit between the brain and the body It consists of a bundle of nerves. Spinal cord injury disrupts communication between the central nervous system and the rest of the body.

Nervous Systems

Nervous Systems. The nerve cell or neuron, is the functional unit of the nervous system. It reacts using sensory cells, by sending an electrical signal along two or more neurons to reach an effector cell. Effector cells are the cells that produce a response.
