Best Answer

The dendrite of a neuron usually receives a chemical signal from another neuron, although a cell body (soma), or sometimes even an axon, of another neuron can receive the signal.

Synapses which occur between an axon and a dendrite are called axodendritic synapses, while synapses between an axon and a cell body are called axosomatic synapses, and synapses between an axon and an axon are called axoaxonic synapses.

The dendrite is the nerve cell that first receives the nervous impulse. In the body the dendrite branch out like a tree and is the first area to get any stimulation.

The events of a nerve impulse?

The electrical impulse in a nerve cell begins when ions move through the cells surface through ion channels.The nerve impulse.A nerve impulse is a wave of excitation that quickly travels within the surface of a neurone (nerve cell). This nerve impulse usually travels on certain parts of the nerve cell: on a dendrite or an axon. Within a neurone the first event depends on the type of 'nerve impulse'; there are two important types:1- nerve impulses generated at dendrites2- self propagating nerve impulses (action potentials) that travel along the axonNerve impulses generated at dendrites.Dendrites feed into the 'cell body' (soma) of a neurone. Nerve impulses that are generated in these dendrites travel toward the cell body.A sequence of events occur at the surface of a dendrite when the nerve impulse is sparked. The first event is transduction; this involves the transformation of one form of energy outside the dendrite into electrical energy within the dendrite.Nerve impulses that travel along axons.Nerve cells often have many dendrites but often only have a single axon. The essential difference between the two parts of the nerve cell is:- in dendrites electrical impulses travel TOWARDS the cell body of the neurone- in the axon the electrical impulses travel AWAY from the cell body of the neuroneThe nerve impulse that travels along an axon begins at the 'base of the axon', where the cell body and axon merge. This site is called the 'axon hillock' and is found to be the site where the first event in the formation of a nerve impulse actually occurs. Again, the first event is transduction at the axon hillock.Conclusion; the first event.For both of the cases above, and for virtually any other case, the nerve impulse begins with a process of transduction. The electrical nerve impulse begins once the first 'ions' leave or enter the nerve cell. Usually sodium ions enter, sometimes calcium ions are the firs to enter, sometimes potassium ions are the first to leave.

Does brain have nerve?

The nervous system is made up of three parts: the receptor, the decider, and the effector. The receptor receives an stimulus and creates an electric impulse to be sent to the brain. The brain receives this impulse and decides what to do in order to react to the stimulus. Your brain then makes a decision and sends out an electric impulse to the effector which moves the muscle or activates a gland in your body which is a reaction to the stimulus.
