Document Summary

Central nervous system: brain and spinal cord (encased in bone) Peripheral nervous system: cranial nerves, spinal nerves, peripheral ganglia. Brain is made up of neurons, glia, and other supporting cells. Neuraxis= imaginary line drawn through the length of the cns ; from the lower end of the spinal cord up to the front of the brain. Top of head and back = dorsal dorsum = back. Front faces the ground = ventral ventrum = belly. Ipsilateral = structures on the same side of the body. Soft and spongy; lies beneath dura mater: pia mater, closely attached to the brain and spinal cord; following every surface convolution. Smaller surface blood vessels of the brain and spinal cord are contained within this layer: between the pia mater and arachnoid membrane = gap called. Filled with csf: ventricular system consists of a series of hollow, interconnected chambers called. Choroid plexus protrudes into all 4 of the ventricles.
