Document Summary
Anatomical directions: you always need a point of reference (we generally use the spinal cord) 90 degree twist in neuraxis: proximal = closer to, distal = far away, lateral = towards the sides, medial = towards the middle. Protecting and supplying the nervous system: meninges: 3 layers, protects brain (also exist in the spinal cord!) *pns has all these membranes except arachnoid membrane: dura matter = just under the bone of skull, fairly thick, quite hard, arachnoid membrane = more spongey, fibre-like arachnoid terabulae. Organization of the nervous system: central: see slide for this, use summary tables in textbook, maybe go back and watch videos, brain ( cephalon = brain, hindbrain (damage often causes death bc controls vital fxns). Includes reticular formation = sleep, arousal, temp reg, motor control. Myelencephalon (medulla = reg of breathing, heart rate: midbrain (mesencephalon) Know only 2 parts: colliculi, superior = visual processing, inferior = auditory processing, forebrain.
