Name and describe the key components of the two major divisions of the nervous system - ANSWERThe nervous system is responsible for coordinating motor functions Central Nervous System: -Responsible for processing and interpreting signals from the senses and the body's inner organs, and programming reflexes and instincts -Brain and Spinal Cord Peripheral Nervous System: -Responsible for sending information to and from the brain and spinal cord -Nerves Identify the structure and function of arachnoid mater - ANSWERArachnoid Matter: the middle layer of the meninges. This net-like membrane includes a subarchnoid space that contains cerebrospinal fluid. What role do sensory fibers play in the nervous system? - ANSWERSensory Nerves: fibers that convey messages toward the central nervous system (brain and spinal cord) What is white matter surrounding the brain made up of? - ANSWERbundles of nerve fibers Describe the cerebrospinal fluid - ANSWERCerebrospinal Fluid: (Spinal Fluid) circulates through the spaces between the meninges, protecting the CNS from injury by spreading the force of impact over a larger area. Also removes metabolic waste from the CNS
