PSYB65H3 Lecture Notes - Lecture 2: Dura Mater, Reticular Formation, Temporal Lobe
Document Summary
Cna brain and spinal cord; being boney/ protected encased in bone. Pns is composed of somatic soma body. Ans made up of sympathetic =activating and parasympathetic=calming. Gray, white & reticular matter: gray matter more dens fence made of neurons / cell bodies. Colour from capillary blood vessels and neuronal cell bodies: white matter less dense made of axons. Colour from axons covered in an insulating layer of glial cells. White b/c they are myelinated: reticular matter. Colour and appearance from cell bodies and axons looks messy of tissue, has both white and grey matter particularly in the brain stem and reticular activating system i. e sleep arousal cut corinal plane by staining we can highlight structure. Wednesday, september 16, 2015 ventricle system, 4 ventricles. 2 lateral, occupy space in both hemispheres the pattern follows the actually surface of the brain come back into the temporal lobe on both sides ventricles are connected via ducts, 3rd occupy space in hypothamlus and thalamus.
