FLASHCARD QUESTION

Front

What is Resting Potential?

Back

Resting Potential is the electrical charge difference across the neuron's membrane when it is not actively transmitting a signal, typically around -70 mV.

2.

FLASHCARD QUESTION

Front

What is the Central Nervous System (CNS) made of?

Back

The Central Nervous System (CNS) is made up of the brain and spinal cord.

3.

FLASHCARD QUESTION

Front

What types of cells are found in the Central Nervous System (CNS)?

Back

The types of cells found in the CNS include Astrocytes, Microglia, and Ependymal cells.

4.

FLASHCARD QUESTION

Front

What happens during depolarization in a neuron?

Back

During depolarization, the charge inside the neuron becomes more positive as sodium ions enter the cell, reversing the resting potential.

5.

FLASHCARD QUESTION

Front

What is the function of Dendrites?

Back

Dendrites are responsible for receiving information from other neurons and transmitting it to the cell body.

6.

FLASHCARD QUESTION

Front

What is an Action Potential?

Back

An Action Potential is a rapid rise and fall in voltage or membrane potential across a cellular membrane, allowing for the transmission of signals along neurons.

7.

FLASHCARD QUESTION

Front

What role do Astrocytes play in the CNS?

Back

Astrocytes support neurons, maintain the blood-brain barrier, and regulate blood flow in the brain.
