Textbook human anatomy physiology edition. Neurons can only be seen using a microscope and can be split into three parts. Bundles of axons known as tracts are part of the. Axon terminals synaptic knobs b.
The chemicalenergy stored in atp is used to fuel most of the biochemical reactionsof the neuron. A axon hillock b cell body c dendrites d axon. The myelin sheath is broken up by points known as the nodes of ranvier or myelin sheath gaps. Joining the signals received by the dendrites and passing them to the axons the next part of the neuron.
Electrical impulses are able to jump from one node to the next which plays a role in speeding up the transmission of the signal. The myelin surrounding the neurons protects the axon and aids in the speed of transmission. In man for example the brainuses 40 ml of oxygen per minute. Soma cell body this portion of the neuron receives information.
