Document Summary

1: motor system (output system) sensory system transmits info from environment into nervous system controls bodily functions (muscles, glands) integrates sensory input, shapes motor output (cognitive system, motivational system. Spinal cord sits above the brainstem + under occipital lobe key element in motor control compares what you want to do with what you are doing refines execution of motor program extension of the cns down spinal column connects to medulla and is enclosed in the vertebrae (protects it) extends down to ~l2 comprises of cervical, thoracic, lumbar + sacral divisions. The target cell can be another neuron or an effector cell (muscle or secretory cell) synpase (em view, axo dendritic) terminal end of axon dendrite component of target cell that receives the synaptic input glial cell astrocyte elements of a synapse (axo dendritic) pre synaptic element = axon post synaptic element = dendrite synaptic vesicles and the synaptic density.
