Scientists believe these structures help transport nutrients and electrical impulses from the cell body to the axon. Axons can be distinguished from dendrites by several features including shape, length, and function. It consists of a microtubule and some microfilaments. Dendrites are one of two types of protoplasmic protrusions that extrude from the cell body of a neuron, the other type being an axon. The axons most commonly arose from the proximal portion of a dendrite rather than directly from the cell body as they typically do in situ. The axon hillock connects it with the neuron’s (Soma) cell body. These axons can be a few millimeters to more than one meter long.Īn axon is the long projection of a neuron with branch-like structures at the end. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body.
Dendrite receives the electric signalĪn axon passes the information from the cell body (Soma) to the dendrite of another neuron in the form of an electrical impulse through the synaptic gap. Function It transmits the electrical signal from the soma or cell body A neuron has many dendrites originating from the cell body. Number (in a single neuron) A neuron has just one axon ( sometimes from a dendrite but generally originating from the soma or cell body). Dendrites are branches that extend from the cell body of a neuron and are responsible for receiving signals from other neurons. Length It is the longest part of a neuron. Question 1 options: a) toward away from b) away from toward c) away from away from d) toward toward, To excite or inhibit an action potential in a receiving neuron, a neurotransmitter must cross the Question 2 options.
