CHEM 1112 Chapter Notes - Chapter 2: Endoplasmic Reticulum, Neuron, Postganglionic Nerve Fibers
Document Summary
Dendritic arborisation - a part of a neurone that shows great variation in the number, size and density of branches. Reflects the organization of afferent inputs to the cell. Neurones possess a nucleus and are located in the centre of the cell body. Nissl substance granules can usually be seen in nerve cell bodies stained with dye. Consists rough endoplasmic reticulum and associated ribosomes: ribosomes contains rna and are the sites of protein synthesis. Neurofilaments structural protein strands that contains a complex meshwork within the. Neurofibrils protein stands that are assembled into a larger structure. Microtubules are involve in the transport of materials throughout the cells. Neuromelanin brownish-black pigment produced as a by-product of the synthesis of catecholamine. Lipofuscin is a yellowish-brown pigment that accumulates in certain neurones with age. Neurotransmitter chemical are store in vesicles within the presynaptic ending.
