The pre-synaptic nerve terminal generally buds from the tip of an axon, while the post-synaptic target surface typically appears on a dendrite, a cell body, or another part of a cell. autonomic ganglia - Clusters of neuronal cell bodies and their dendrites are essentially a junction between automatic nerves originating from the central nervous system. **Presynaptic:** Situated in front of or occurring before a synapse **Synapse:** The junction across which a nerve impulse passes from an axon terminal to a neuron, muscle cell, or gland cell. **Nerve Impulse:** A wave of physical and chemical excitation along a nerve fiber in response to a stimulus, accompanied by a transient change in electric potential in the membrane of the fibre. **Ribosomes:** A ribosome is a small, dense organelle in cells that assembles proteins
 * morphological**-the adjective to do with the study of the shape of an object. Bill & Monica
 * endoplasmic reticulum** - Membrane system that ramifies through the cytoplasm.
 * Golgi apparatus** - A cell structure devoted to processing the protiens synthesized in the endoplasmic reticulum.
 * Synaptic** - Involoving the synapsis
 * arborization** - the branching of nerve fibres like that of a tree
 * presynaptic** before a synapse
 * postsynaptic:** Chemical synapses are specialized junctions through which the cells of the nervous system signal to each other and to non-neuronal cells such as those in muscles or glands.
 * axon** an axon is a long slender projection of a nerve cell that conducts electrical impulses away from the neuron's cell body. Bill & Monica
 * retinal amacrine** - a neuron which only communicates with other neurons and it relays data from the Retina directly to the brain
 * synapse** The junction between nerve cells where a nerve impulse is transferred from one neuron to another. Chemical synapses are specialized junctions through which the cells of the nervous system signal to each other and to non-neuronal cells such as those in muscles or glands.
 * synaptic vesicles** - In a neuron, synaptic vesicles, store the various neurotransmitters that are released during calcium-regulated exocytosis at the presynaptic terminal into the synaptic cleft of a synapse. The vesicles are essential for the propagation of nerve impulses between neurons and are constantly recreated by the cell.
 * Neurotransmitter:** A chemical substance, such as acetylcholine or dopamine, that transmits nerve impulses across a synapse.
 * Exocytosis**: A process of cellular secretion or excretion in which substances contained in vesicles are discharged from the cell by fusion of the vesicular membrane with the outer cell membrane.
 * Organelle:** A discrete structure of a cell having specialized functions


 * salient-**an adjective, prominent or conspicuous
