Neuron Transmission flashcard

Front

What are receptors in the context of neuron transmission?

Back

Receptors are specialized protein molecules located on the surface of neurons that bind to neurotransmitters, allowing for communication between neurons.

Front

What is a synapse?

Back

A synapse is the junction at which a neuron meets another cell, facilitating the transmission of nerve impulses.

Front

What does the letter 'C' represent in a labeled neuron diagram?

Back

The letter 'C' represents the Cell Body, which contains the nucleus and organelles of the neuron.

Front

What does the letter 'A' represent in a labeled neuron diagram?

Back

The letter 'A' represents the Dendrite, which receives signals from other neurons.

Front

What is the tiny gap between neurons called?

Back

The tiny gap between neurons is called the synapse, where neurotransmitters are released to transmit signals.

Front

What role do calcium channels play in neuron transmission?

Back

Calcium channels allow calcium ions to enter the neuron, triggering the release of neurotransmitters into the synapse.

Front

What is the function of neurotransmitters?

Back

Neurotransmitters are chemical messengers that transmit signals across the synapse from one neuron to another.

Front

What is the axon in a neuron?

Back

The axon is a long, slender projection of a neuron that conducts electrical impulses away from the cell body.

Front

What is the function of the myelin sheath?

Back

The myelin sheath is an insulating layer that surrounds the axon, speeding up the transmission of electrical signals.

Front

What are dendrites?

Back

Dendrites are branching extensions of a neuron that receive signals from other neurons and transmit them to the cell body.
