Document Summary
Neurons: individual cells in the nervous system that receive, integrate & transmit information: responsible for all of our thoughts and memories and the control of our actions. Information is received at the dendrites, is passed through the soma and along the axon, and is transmitted to the dendrites of other cells at meeting points called synapses. Parts of the neuron: soma/cell body: contains the cell nucleus and much of the chemical machinery common to most cells, dendrite: the parts of a neutron that are specialized to receive information (shaped like a branch) Derived from special types of glial cells. Speeds up the transmission of signals that move along axons. Degeneration of myelin sheath causes ms (a disease characterized by the loss of muscle. Account for over 50% of the brain"s volume. Supply nourishment to neurons, help remove neurons" waste products + provide insulation around many axons.
