Lecture 1- the nervous system & the neuron: resting neuron voltage: -65mv, glutamate is the most common neurotransmitter, sodium, potassium, calcium and chloride are involved in neuro-electric activity. Central nervous system: brain, brain stem & spinal cord, all parts of nervous system within bone. Peripheral nervous system: peripheral nerves, all parts of nervous system outside of bone. In order: (person standing at 90 degree angle: cervical, thoracic, lumbar, sacral. How are neurons similar to other cells: enclosure: lipid bilayer membranes, organelles. How do they differ: their shape (orthology, unique morphology (dendrites, axons, electrically excitable (ap) Glial cells: most common type of cell in the nervous system, astrocyte- maintain ionic environment, oligodendrocyte- myelinate axons of neurons, microglia- scavenge cellular debris. Towards the front, the nose: caudal, towards the tail, dorsal, towards the back, ventral, towards the stomach. Symmetry: the brain is symmetrical from one side to another.
