Introduction: The brain is made up of about 86 billion nerve cells (also called “neurons”). A neuron has 4 basic parts: the dendrites, the cell body (also called the “soma”), the axon and the axon terminal.

Dendrites. A branch like structure that “receives” information and carries it into the neuron.Soma (Cell Body) It’s surrounded by dendrites and it is the brain of the neuron.Axon. Terminal Buttons. Synapse. What are the 5 parts of a major neuron?
They have three distinct parts, including a cell body, axon, and dendrites. These parts help them to send and receive chemical and electrical signals.

Soma. body of neuron; responsible for health of neuron and speed of signal.Dendrites. input of neurons; receive electric signals.Axon. Longest part of the neuron; carrier; highway for signal.myelin sheath. layer of fat that wraps axon; protects and speeds up signal.neural impulse. terminal branches.

Dendrites. rootlike parts of the cell that stretch out from the cell body. Soma/Cell body. contains nucleus and other parts of the cell needed to sustain its life.Axon. Myelin sheath. Terminal Buttons. Synapse. Neurotransmitters. Synaptic Vesicles.
For the spinal cord though, we can say that there are three types of neurons: sensory, motor, and interneurons.
Sensory neurons. Motor neurons. Interneurons. Neurons in the brain.
The correct answer is Collecting duct. The collecting duct is not a part of Neuron.
Neurons are the structural and functional unit of the nervous system. All neurons have three different parts – dendrites, cell body and axon. The neuron structure is specially adapted to carry messages over large distances in the body quickly in the form of electrical signals.
Their function is to send electrical impulses and chemical signals to and from the brain. Most neurons have three parts, including a cell body, which contains the nucleus and the cytoplasm, an axon, which transmits information away from the nucleus, and dendrites, which receive messages from other neurons.
Explanation. The three types of neurons are sensory neurons, motor neurons, and interneurons.
Dendrites. Dendrites and axons are cytoplasmic extensions, or processes, that project from the cell body. They are sometimes referred to as fibers. Dendrites are usually, but not always, short and branching, which increases their surface area to receive signals from other neurons.
