SteveParts of a neuron include the cell body (soma), dendrites, axon, axon terminals, and synapses. Dendrites receive signals from other neurons, while the axon transmits signals to other neurons. Axon terminals release neurotransmitters that signal communication between neurons at synapses.
The neuron is made up of:
- the soma (neuron cell body), which contains the nucleus and other main organelles
- the dendrites (branching parts, stemming from the soma, which receive inputs from other neurons)
- the axon, which is the primary output conduit for the neuron, sending the action potential forward
- the myelin sheath, which surrounds different portions of the axon to aid in action potential conduction
- the axonal terminal, which is the end of the axon and contains neurotransmitter vesicles awaiting release into the synaptic cleft (the gap following the neuron, connecting to another neuron or muscle cell)

What parts of a neuron is capable of generating a graded potential?
The dendrites portion of a neuron will generate a potential.
Parts of a multipolar neuron its order of receiving nerve impulses?
The parts of a multipolar neuron include the dendrites which receive nerve impulses, the cell body which integrates the signals, and the axon which conducts the signals away from the cell body. In terms of receiving nerve impulses, the order is generally dendrites, cell body, and then axon.
In a neuron impulses move?
In a neuron, impulses move through electrical signals known as action potentials. These action potentials are generated when a neuron receives enough stimulation to reach a threshold, causing a rapid change in membrane potential. The action potential then travels down the length of the neuron's axon until it reaches the next neuron or target cell.
State the three main parts of a neuron and describe how an impulse travels through a neuron?
The three main parts of a neuron are the cell body, dendrites, and axon. An impulse travels through a neuron when it is first received by the dendrites, then transmitted through the cell body, and finally travels down the axon to reach the next neuron or target cell.
Where neuron cell bodies located?
The cell body, called the SOMA, is the main part of the neuron. It is the main metabolic center or region of the neuron. The neuron has 3 parts: DENDRITES (inputs), SOMA (cell body), and AXON (output). The axon is the part which FIRES when sufficient inputs reach it at the axon hillock.
