What is the structure of an axon?
Function: The two work together. Axons help messages move through your body systems, and dendrites receive and process those messages from the axons. Quantity: A neuron may have just one axon, while it may have more than one set of dendrites.
What is the function of the axon in a neuron?
axon, also called nerve fibre, portion of a nerve cell (neuron) that carries nerve impulses away from the cell body. A neuron typically has one axon that connects it with other neurons or with muscle or gland cells. Some axons may be quite long, reaching, for example, from the spinal cord down to a toe.
What structure of neurons covers the axon?
The axon is covered by a myelin sheath. The axon passes information to the next neuron or other cell in the body. A myelin sheath. The axons have a protective covering called myelin.
What is the shape of axon?
Shape. Dendrites are usually thin while axons typically maintain a constant radius. Length. Dendrites are limited to a small region around the cell body while axons can be much longer.
What is a neuron write the structure and function of neuron?
neurons are specialized cells of the nervous system that transmit signals throughout the body. Neurons have long extensions that extend out from the cell bodycalled dendrites and axons. Dendrites are extensions of neurons that receive signals and conduct them toward the cell body.
What is the structure of a neuron?
A neuron has three main parts: dendrites, an axon, and a cell body or soma (see image below), which can be represented as the branches, roots and trunk of a tree, respectively. A dendrite (tree branch) is where a neuron receives input from other cells.
What is a neuron write the structure and function of a neuron?
Nervous system cells are called neurons. They have three distinct parts, including a cell body, axon, and dendrites. These parts help them to send and receive chemical and electrical signals.
What is the structure at the end of an axon that produces neurotransmitters?
Axon terminal
A. Motor neuron; B. Sensory neuron; C. Relay neuron;
| Term | Function |
|---|---|
| L. Axon terminal | 7. The structure at the end of an axon that produces neurotransmitters to transmit the nerve impulse across the synapse. |
| D. Nerve impulse | 8. The high speed signals that pass along the axons of nerve cells. |
What is the structure of neuron and explain its function?
The structure of neuron is The signals received are in the form of electrical signals. Neuron comprises dendrite, axon and cell body. Dendrites receives messages from the surrounding and sends it to the cell body. Cell body consists of nucleus, mitochondria and other organelles.
