What are different types of dendrites?

dendrites are one of the three parts that make up most of the nerve cells or neurons. Almost all neurons have a similar structure that contains one axon; one cell body, also called soma; And many dendrites. While each neuron has a body of axon and cells, it may or may not have dendrites. When they are present, they can be found in one of two forms that are apical or basillary.

Regardless of the type of dendrite, the function is the same. The surface is a place where nerve pulses from the end ends of the axons of other neurons are accepted. Nerve pulses are transmitted or inhibited in synapses by chemical stimulation by release of neurotransmitters. This pulse is usually transmitted directly to the cell body or along the axon to a centrally placed cell body based on the type of nerve cell.

Two types of dendrites differ in several basic ways. Basilar Dendrite does not have a stem that can be seen in apical dendritit. In most cases, Basilar of Denobřeky are found in a larger numberthan apical. Another difference is that apical dendrites usually occur in the brain cortex.

apical dendrites can be further divided into two other groups, distal and proximal. Those in the distal group are longer and the project from the cellular body at the opposite end of the axon. Given their length, they say they create a non -nocal synapses that are not close to the nerve cell. The apical dendritus belonging to the proximal group is much shorter and receives impulses from other neurons that are much closer, including interneurons.

Another way to classify dendrites is whether they are barbed or smooth. These categories are based on the presence or absence of dendritic spines. No smooth and nerve pulse is accepted directly on the shaft. The spines have a dendritic spine, so the nerve impulse is a received along the shaft and along the spines that protrude from it.

Smooth and barbed dendritey often carry different types of messages to the nerve cell. In most cases, the synapses are found in smooth dendritus, which means that the neurotransmitter that is released, inhibits or reduces the chance that the pulse is transmitted along the neuron. Synapses found in barbed dendrites are usually excited. This means that there is the opposite effect, so the neurotransmitter will stimulate the pulse to continue along the neuron.
