Document Summary
Function of the cerebral hemispheres, brain vascular supply, information is passed form the axon to the dendrite across a gap (20-50 nm) called the synapse. Based on the positions relative to synapse, events that occur in the axon referred to as presynaptic and events that happen in the dendrite referred to as postsynaptic. dendrites increase in surface area available for the reception from the axons of other neurons. The extent of branching of the dendrites gives indication of the number of connections/synapses it makes with incoming axons. dendrites are often covered with tiny spines, which grow and retract in response to experience. The spines can form synapses with other neurons. the axon is thought of as the information sender. It s a long fiber or wire that can pass its message along to many different cells.
