Document Summary
Gap junction: neurites of two cells connected by a gap junction, an enlargement showing gap junction channels. Ions and small molecules can pass in both directions through these channels: six connexin subunits comprise of one connexon. Many gap junction channels comprise one gap junction. The components of a chemical synapse: axon terminal, mitochondria, secretory granules, synaptic cleft, synaptic vesicles, receptors, postsynaptic dendrite, active zone, postsynaptic density, membrane differentiations. Chemical synapses, as seen with the electron microscope: a fast excitatory synapse in the cns, a synapse in the pns, with numerous dense core vesicles. Synaptic arrangement in the cns: an axodendritic synapse, an axosomatic synapse, an axoaxonic synapse. Various sizes of cns synapses: larger synapses have more active zones. The synthesis and storage of different types of neurotransmitters: peptides. A precursor peptide is synthesized in the rough er. The precursor peptide is split in the golgi apparatus to yield the active neurotransmitter.
