What part of a neuron attaches the cell body to the axon?
The part of a neuron that attaches the cell body to the axon is called the axon hillock. It is located at the base of the cell body and is responsible for integrating incoming signals to generate an action potential.
What composed of a cell bodydendritesand axon?
Nerve cell or neuron
What are the 3 main structures of a neuron?
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.
A long structure leaving the cell body that action potential travel along is called the?
It is the Axon
What are the 4 parts of neuron?
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.
What is the region of a neuron where the axon originates?
The region of a neuron where the axon originates is called the axon hillock. This specialized area is located at the junction of the cell body (soma) and the axon. It plays a critical role in integrating incoming signals and determining whether to initiate an action potential, which is essential for transmitting nerve impulses along the axon.
Is and axon bulb and an axon hillock the same thing?
axon hillock = where cell body meets the axon axon bulb = end of the axon...lies very close to the dendrites of another neuron so impulses can pass over the synapse. AP Biology student *
What is the function of the axon hillock?
An axon hillock is part of a neuron that acts as a bridge between the cell body and the axon. Electrical impulses from the dendrites and cell body are summed at this point, which is then sent down the axon.
In what direction does an action potential move in a nerve cell?
An action potential in a nerve cell moves in one direction only: from the cell body, down the axon, and towards the synaptic terminals. This is known as an all-or-nothing response where the signal propagates along the neuron in a unidirectional manner.
What part of a neuron attaches the cell body to the axon?
The part of a neuron that attaches the cell body to the axon is called the axon hillock. It is located at the base of the cell body and is responsible for integrating incoming signals to generate an action potential.

What part of the neuron carries impulses away from the neuron?
Axons send information away from a cell body.
What are the 3 main structures of a neuron?
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.
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 are the parts of a nerves?
the parts of the nerve cell are cell body,dendrites,and axon, axon teminals, nucleus,
Where do action potentials occur?
Action potentials occur along the axon of a neuron, where the electrical signals are transmitted from the cell body to the axon terminals. The action potential is initiated at the axon hillock and propagates down the axon to trigger the release of neurotransmitters at the synapse.
What part of the brain takes away information to the cell body?
axon
