Pacific Time vs. Mountain Time — What's the Difference?

By Tayyaba Rehman — Published on October 18, 2023
Pacific Time (PT) is the time zone west of Mountain Time (MT). While PT covers the U.S. West Coast, MT spans the region to its east. PT is one hour behind MT.
Pacific Time vs. Mountain Time — What's the Difference?

Difference Between Pacific Time and Mountain Time


Key Differences

Ganglion: A ganglion refers to a collection of nerve cell bodies located outside the central nervous system, primarily in the peripheral nervous system. Ganglia provide relay points and intersections for transmitting neurological signals. Synapses, on the other hand, are the actual points of signal transmission.
Synapse: The term synapse designates the specialized junctions through which neurons signal to each other and to non-neuronal cells like muscles or glands. They are integral to the propagation of nerve impulses. Ganglion, in contrast, represents groupings of nerve cell bodies.
Structural Differences: A ganglion generally presents as a visible bump or node containing numerous nerve cell bodies. In contrast, a synapse is microscopic and involves the end of one neuron, the synaptic cleft, and the beginning of another neuron. The distinction between ganglion and synapse lies in their composition and visibility.
Functional Differences: Ganglia serve as hubs in the peripheral nervous system, housing cell bodies of neurons. They often relay and process signals. Synapses are the points where the actual transmission of the signal occurs between neurons, ensuring communication within the nervous system.
Location and Presence: Ganglia are mainly seen in the peripheral nervous system, although some exist in certain brain structures. Synapses are ubiquitous throughout both the central and peripheral nervous systems, facilitating neural communication.

Common Curiosities

How do ganglia and synapses relate to each other?

Ganglia house neuron cell bodies, while synapses are where these neurons communicate.

What is a ganglion in simple terms?

A ganglion is a cluster of nerve cell bodies located outside the central nervous system.

Can you see a ganglion?

Yes, some ganglia can be seen and felt as bumps, especially those near the skin.

Are synapses only present in the brain?

No, synapses are found throughout the central and peripheral nervous systems.

What's the primary role of a synapse?

A synapse is where two neurons meet and transmit signals to each other.

How do drugs affect synapses?

Many drugs can enhance or inhibit neurotransmitter activity at synapses, affecting signal transmission.

Do all neurons in a ganglion have the same function?

No, a ganglion can contain various neurons with different functions.

Why are synapses important?

Synapses are essential for all neural functions, from reflexes to complex thought processes.

How do synapses ensure one-way communication?

Synapses are designed so that neurotransmitters only flow from the presynaptic to the postsynaptic neuron.

What causes a ganglion cyst?

The exact cause is unclear, but joint or tendon irritation is often associated.

Can a ganglion be harmful?

While many are harmless, some ganglion cysts or tumors may require medical attention.

Is the synapse only about electrical transmission?

No, synapses can be electrical or chemical, with the latter involving neurotransmitters.

Can ganglia be found in the brain?

While most are in the peripheral nervous system, certain brain structures like the basal ganglia exist.

Are ganglia unique to humans?

No, many vertebrates have ganglia in their nervous systems.

How many synapses does a neuron have?

A neuron can form thousands of synapses with other cells.
