Document Summary
Neurons/ glia: are the specialized cells of the nervous system and they are specialized in both structure and function : glia: provides support functions and neurons are the communicators. Neurons react and respond to stimuli and they are basis of the behaviour. Neurons also learn and store information about the environment. Distinctive structural feature of a neuron is its shape. Glia: dendrites which receive incoming information from other neurons, soma cell body, which contains the genetic machinery and most of the metabolic machinery needed for common cellular functions. Axon sending neural information to other neurons: info is passed from the axon to the dendrite across a gap: called synapse. Events that occur in the axon, such as presynaptic (in the axon events) and postsynaptic (events that happen in the dendrite) Dendrites: has spines that can form synapses themselves with other neurons. Axons are thought to be information senders.
