PSY353H5 Lecture Notes - Lecture 1: Prefrontal Cortex, Peripheral Nervous System, Chemical Synapse
Document Summary
Directional terms: 3 planes and 6 views, axial = if cut the brain across the axis. If make axial slice to (1) superior view, create (2) horizonal view. 2)sagittal = if cut the brain down from anterior to superior end. Take (3) lateral view, make sagittal slice, create (4) medial view: coronal. Take lateral view, make coronal slice, create (5) coronal view (6) inferior view least viewed. Dendrites : extension of cell body that receives info from other neurons; input zone receive info from other neurons or specialized sensory structures. Axon; conduction zone where the nerve"s electrical signal may be actively propagated from cell body to axon terminals. Axon terminals (no myelin sheath) aka synaptic bouton; output zone; the end of a axon/axon terminal; forms synapse on a neuron or other target cell: directions, superior (above) to inferior (below) aka dorsal to ventral.
