Axon Hillock
The three main structures of a neuron are the cell body (soma), dendrites, and axon. The cell body contains the nucleus and other organelles, the dendrites receive signals from other neurons, and the axon transmits signals to other neurons or cells.
The three main parts of a neuron are the dendrites, the axon, and the soma. The dendrites are the nerve endings, the axon is the body, and the soma is the cell body.
Apex question is which is a part of a neuron that sends out messages answer axon
Dendrite to soma to axon ;)
The three main parts of a neuron are the cell body (soma), dendrites, and axon. The cell body contains the nucleus and organelles, dendrites receive signals from other neurons, and the axon transmits signals to other neurons.
The area where the axon emerges from the soma is called the axon hillock. This region is crucial for the initiation of action potentials, as it integrates incoming signals and determines whether to transmit an electrical impulse down the axon. The axon hillock is characterized by a high density of voltage-gated sodium channels, which play a key role in the generation of action potentials.
the two types are anterograde transport and retrograde transport. anterograde is the flow of new or recycled cell products from the soma to the axon terminals for growth or regeneration in the axon. retrograde is the return from the axon terminal back to the soma so products can be degraded or recycled.
A typical neuron possesses a cell body called soma, dendrites and axon. The sensory nerve cells receiving information from the skin are pseudounipolar cells having two axon. One axon extends centrally towards the spinal cord and the other axon extends towards the skin. The soma of these nerve cells having neurofilaments of specialized proteins receive sensory information through electric and chemical signals called neurotransmitters.A typical neuron possesses a cell body called soma, dendrites and axon.

soma (cell body), axon, and axon terminals. I left out dendrites, because there are some kinds of neurons (sensory neurons) which don't have dendrites, but rather have axons which come from a sense receptor cell, come to but do not enter the soma, where the impulse continues onalong a second branch of the axon stub which comes out from the soma. In other words, a single axon (or perhaps a fused axon and dendrite?) comes out from the soma, where it branches into two, one of which goes to the receptor cell to receive an impulse (and is myelinated and conducts an action potential), and the other goes to the spinal cord or brain.
The four parts of a neuron are dendrites, cell body (soma), axon, and terminal branches (axon terminals). Dendrites receive signals from other neurons and transmit them towards the cell body. The axon carries signals away from the cell body to other neurons or cells, and the terminal branches release neurotransmitters to communicate with these target cells.
