Neurons (or nerve cells) come in three structural types, depending on how many fibres they have: Multipolar neurons have many fibres attached to the cell body. One fibre, the axon, is longer than the others and carries the electrical impulses away from the cell body. The other fibres, called dendrites, are shorter and carry impulses to the cell body. Bipolar neurons have two fibres attached to the cell body, one denfrite and one axon. Unipolar neurons have a single fibre attached to the cell body which then branches into two.

The most common type of neuron found in the central nervous?

The most common type of neuron found in the central nervous system is the multipolar neuron. These neurons have many dendrites and a single axon extending from the cell body. Multipolar neurons are involved in processing and transmitting information in the brain and spinal cord.

The most type of neuron in the human body is?

Multipolar neurons This is the most common type of neuron, with one axon and many dendrites. Multipolar neurons are so-named because they have many (multi-) processes that extend from the cell body: lots of dendrites plus a single axon. Functionally, these neurons are either motor (conducting impulses that will cause activity such as the contraction of muscles) or association (conducting impulses and permitting 'communication' between neurons within the central nervous system).


What connects sensory to motor neuron?

Interneurons(also called relay neuron, association neuron, connector neuron or local circuit neuron) are multipolar neurons that connects sensory neurons to motor neurons.


What determine whether a neuron is unipolar bipolar multipolar?

The location of dendrite and axon: If dendrite and axon emerge from same process, the neuron is unipolar. If dendrite and a single axon emerge from opposite ends of the soma, the neuron is bipolar. If the neuron has more than 2 dendrite it is called multipolar.


Why is an efferent neuron multipolar?

Efferent neuron is a neuron that regulate the action of a muscle, gland, or other effector tissue. It is a neuron which produces impulses outward from the brain or spinal cord, so its consider a multi-polar neuron.


What is the function of the giant multipolar neuron?

The giant multipolar neuron helps to coordinate movement and maintain muscle tone in invertebrates. It plays a key role in the coordination of activities within the nervous system and the conduction of nerve impulses along its large axon.
