Document Summary
The functions of the nervous system are distributed in the structural organization of the nervous system. Proper functioning of each ns division depends upon interdependent afferent/efferent cooperation. Conducts nerve impulses to and from the brain. Process some sensory information to allow reflex (motor) actions. It is a centre for spinal reflexes (gray matter) and is the neural communication to and from the brain (white matter) Spinal cord structures and meninges fig 14. 2. Landmarks and grey matter functional organization of the spinal cord fig 14. 4. White matter columns and comparative functional organization in the spinal cord fig 14. 4. General division and functions of the brain fig 16. 1. *** know the diagrams and structures of the ns will be tested more on that on the exam***** Meninges and fluid (csf/venous) relations fig 16. 45. Protection of the brain from contact with cranium and in response to external blunt force. Transport of nutrients, chemical messengers and waste materials.
