Document Summary

Golgi stain: stai(cid:374)s a(cid:454)o(cid:374)s, though o(cid:374)l(cid:455) (cid:1005)(cid:1004)% a(cid:374)d does(cid:374)"t sho(cid:449) (cid:374)eigh(cid:271)ors. Nissl stain: stains rna blue, distinguishes grey from white matter (cell bodies vs. fibers) Weigert stain: stains myelin deep blue, and degenerated portions light yellow. Cytoarchitecture: the stud(cid:455) of (cid:272)ellular (cid:272)o(cid:373)positio(cid:374) of the (cid:271)od(cid:455)"s tissues u(cid:374)der a (cid:373)i(cid:272)ros(cid:272)ope. Neuron: a specialized cell transmitting nerve impulses; a nerve cell. Neurites: any projection from the cell body of a neuron. This projection can be either an axon or dendrite. Axon: (cid:374)er(cid:448)e fi(cid:271)er that (cid:272)o(cid:374)du(cid:272)ts ele(cid:272)tri(cid:272)al i(cid:373)pulses a(cid:449)a(cid:455) fro(cid:373) the (cid:374)euro(cid:374)"s (cid:272)ell (cid:271)od(cid:455), (cid:449)orks (cid:271)est (cid:449)he(cid:374) myelinated. Dendrites: short branched extension of a nerve cell, along which impulses received from other cells at synapses are transmitted to the cell body. Afferent: conducting or conducted inward or toward something. Efferent: conducted or conducted outward or away from something. Sensory neuron: nerve cells that transmit sensory information.
