What are dendrites?

A dendrite (tree branch) is where a neuron receives input from other cells. Dendrites branch as they move towards their tips, just like tree branches do, and they even have leaf-like structures on them called spines.

How do neurons communicate?

“Neurons communicate with each other through electrical and chemical signals,” explains Barak. “The electrical signal, or action potential, runs from the cell body area to the axon terminals, through a thin fiber called axon. Some of these axons can be very long and most of them are very short.

What are the steps of action potential?

An action potential has three phases: depolarization, overshoot, repolarization.

What is axon and dendrite?

Axon originates from the discharging end of Neuron while Dendrite originates from the receiving end of Neuron. You can only find one Axon per Nerve Cell whereas there are various Dendrites within a Nerve Cell. The Axon has the long-tail structure and Dendrite has short, fibrous, root-like structure.

What is a axon?

Each neuron in your brain has one long cable that snakes away from the main part of the cell. This cable, several times thinner than a human hair, is called an axon, and it is where electrical impulses from the neuron travel away to be received by other neurons.

What type of communication is used within the neuron?

Neurons communicate using both electrical and chemical signals. Sensory stimuli are converted to electrical signals. Action potentials are electrical signals carried along neurons. Synapses are chemical or electrical junctions that allow electrical signals to pass from neurons to other cells.

How do neurons communicate at the synapse 2.2 2?

Neurons communicate with each other via electrical events called ‘action potentials’ and chemical neurotransmitters. At the junction between two neurons (synapse), an action potential causes neuron A to release a chemical neurotransmitter.

What is occurring in the area between #2 and 3?

What is occurring in the area between #2 and #3? Sodium ions are entering the axon and causing depolarization.
