5. Mitochondrium-this is the part of the cell responsible for the supply of energy in the form of ATP (adenosine triphosphate). Neurons need an enormous amount of energy. The brain is one of the most metabolically active tissues in the body.In man, for example, the brain uses 40 ml of oxygen per minute.t is from here that the electrical firing known as an action potential usually occurs. 5. Nerve Ending (Presynaptic Terminals) Synapses are the junctions formed with other nerve cells where the presynaptic terminal of one cell comes into 'contact' with the postsynaptic membrane of another.
A simple structure designed for a complex task. A typical neuron is divided into three parts: the cell body, the dendrites and the axon. The cell body (green color), the center of the neuron, extends its processes called the axon and the dendrites to other cells.Dendrites typically branch profusely, getting thinner with each branching (blue color).etting really into it. The cell body is the central part of the neuron. It contains the nucleus of the cell (that carries all the genetic material) and numerous organelles that allow protein synthesis (endoplasmic reticulum, golgi, etc) and energy production (mitochondria).
