- Cell body (soma): Contains the nucleus and organelles necessary for normal cell function.
- Dendrites: Branch-like extensions that receive signals from other neurons and transmit them towards the cell body.
- Axon: Long, slender projection that carries electrical signals away from the cell body to communicate with other neurons or muscle cells.

What parts of a neuron is capable of generating a graded potential?
The dendrites portion of a neuron will generate a potential.
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.
What about the diameter of the nerve fiber?
The smallest neuron is at .004mm. The longest neuron, which runs from the lower spinal cord to the big toe, is over a meter long!
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.
Name the 3 main parts of a neuron?
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.
What are the two parts the neuron is split up into?
There are actually 3 parts to a neuron. The dendrites are tree branch like projections that receive nerve impulses from another neuron, the cell body that contains the nucleus, and the axon, a long fiber that carries the nerve impulse away from the cell body to the next neuron.
What are the Parts of neuron?
1. The cell body (or soma) 2) The axon 3) The dendrites
What are the three parts of a neuron-?
The three main parts of a nueron are: the dendrites, the axon, and the cell body.
What is the 3 types of neuron?
one type of neuron is the motor neuron
What parts of a neuron is capable of generating a graded potential?
The dendrites portion of a neuron will generate a potential.
What neuron parts that does not have missile bodies?
Axon
What are the five parts of a reflex arc?
The five parts of a reflex arc are the receptor, sensory neuron, integration center, motor neuron, and effector. The receptor detects a stimulus, and the sensory neuron carries this information to the integration center. The integration center processes the information and sends a signal to the motor neuron, which then activates the effector to produce a response.
What are the five parts of a reflex?
Five parts of a reflex arc are the receptor, sensory neuron (afferent), integration center, motor neuron (efferent), and effector.
What are 3 parts of a neuron?
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.
What are the parts of neuron and its function?
The three main parts of a neuron are the soma (cell body), the axons, the long trailing output of a neuron and the dendrite or dendritic tree. Almost all neurons have axons, but not all axons have a dendritic tree.
What are the parts and function of neuron?
The three main parts of a neuron are the soma (cell body), the axons, the long trailing output of a neuron and the dendrite or dendritic tree. Almost all neurons have axons, but not all axons have a dendritic tree.
