While the neural architecture responsible for the transmission of electrical impulses has been known for more than a century, the basic biology behind how a neuron acquires its one and only axon ...

Multipolar neurons. These neurons have a single axon and symmetrical dendrites that extend from it. This is the most common form of neuron in the central nervous system.

While the body of a neuron is small, its axon can extend far up or down the spinal cord, which is about one and half feet long in humans. Along that distance, the axon branches out to make ...

Between the axon of a transmitting neuron and the dendrite of a receiving neuron is a gap called the synapse —the site at which signals are passed between the brain cells.

We explain what a neuron looks like, what it does, and how it works. Health Conditions ... Axon — this long projection carries information from the soma and sends it off to other cells.

Stylized axon arbor of a neuron. Yellow circle: root vertex at the axon initial segment; red circles: bifurcation vertices; black circles: terminal vertices at the axon's synaptic terminals.

But how do brain cells send messages? The first step in this messaging process is the action potential, or a wave of electricity triggered in the nerve cell, or neuron.The neurons found in the ...

Alzheimer's disease (AD) is a debilitating neurodegenerative condition that affects a significant proportion of older people ...

What am I looking at? Here we see four individual dendrites with dendritic spines (1) extending from the main dendrite (2). The dendrites were colored to distinguish them from each other.. Biology in ...

Synapses are well-known to occur between the axon of one neuron and the dendrites of other neurons, but had never been observed between the neuron's axon and the primary cilium.

Watanabe had initially seen repeated axon pearling in the nervous system of worms and grew more curious about the structures ...
