Document Summary
Golgi the nervous system is composed of a network of interconnected fibers a nerve net. Cajal - nervous system is made up of discrete cells that begin life with a rather simple structure that becomes more complex with age: cajal"s (cid:374)eu(cid:396)o(cid:374) theo(cid:396)(cid:455) that neurons are the functional units of the nervous system. Cell body/soma core region of the cell containing the nucleus and other organelles for making proteins. Dendrites branching extension of a (cid:374)eu(cid:396)o(cid:374)"s (cid:272)ell (cid:373)e(cid:373)(cid:271)(cid:396)a(cid:374)e that g(cid:396)eatl(cid:455) i(cid:374)(cid:272)(cid:396)eases the su(cid:396)fa(cid:272)e area of the cell and collects information from other cells. Axon root or single fiber, of a neuron that carries messages to other neurons. Neural connections: the appearance of each neuron tells us something about the connections that is must make. Neurons acquire information from sensory receptors, pass the information on to other neurons, and make muscles move to produce behaviors. They encode memories and produce our thoughts and emotions.
