It is surrounded by a Myelin sheath (a kind of fatty material) in the form of Schwann cells. Scientists believe these structures help transport nutrients and electrical impulses from the cell body to the axon. In many instances, these developmental processes are regulated by the interplay between neurons and glial cells that act instructively during neural remodeling. It consists of a microtubule and some microfilaments. Most axon pruning involves the removal of axons that had already made synaptic connections thus, axon pruning is tightly associated with synapse elimination. 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. These include many short, branching processes, known as dendrites, and a separate process that is typically longer than the dendrites, known as the axon. The end of an axon is usually connected to dendrites of other neurons (sometimes to muscle or gland cells) via junctions called synapses. 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. Dendrites - It takes information to the cell body. Function It transmits the electrical signal from the soma or cell body A neuron has 3 parts: the dendrites, the cell body (also called the soma), the axon. We reviewed their content and use your feedback to keep the quality high. Who are the experts Experts are tested by Chegg as specialists in their subject area. A neuron has many dendrites originating from the cell body. Question: Part A Which structure is highlighted cell body neuroglial cell dendrite axon hillock. Number (in a single neuron) A neuron has just one axon ( sometimes from a dendrite but generally originating from the soma or cell body). Axon and dendrites are both parts of a neuron, which is a nerve cell that transmits information throughout the body. Length It is the longest part of a neuron. The proper word to use depends on the context.
