Nervous System Medical Terminology and disorders

Front

What is hyperpolarization in a neuron?

Back

Hyperpolarization is an increase in the membrane potential of a neuron, making it more negative than the resting potential, which decreases the likelihood of an action potential.

Front

Which lobe of the brain is responsible for processing auditory information?

Back

The temporal lobe is responsible for receiving auditory information and contains memory centers.

Front

What is the function of the frontal lobe?

Back

The frontal lobe is involved in decision making, problem solving, and controlling behavior and emotions.

Front

What sensory information does the parietal lobe process?

Back

The parietal lobe processes sensory information from the skin, including touch, temperature, and pain.

Front

What does the prefix 'HYPER' mean in medical terminology?

Back

The prefix 'HYPER' means 'above' or 'excessive'.

Front

What is the role of the occipital lobe?

Back

The occipital lobe is primarily responsible for visual processing.

Front

Define action potential in the context of neurons.

Back

An action potential is a rapid rise and fall in voltage or membrane potential across a cellular membrane, allowing neurons to transmit signals.

Front

What is the significance of myelin in the nervous system?

Back

Myelin is a fatty substance that insulates axons, increasing the speed of electrical impulses along the nerve cells.

Front

What is synaptic transmission?

Back

Synaptic transmission is the process by which signaling molecules called neurotransmitters are released by a neuron and bind to receptors on another neuron, facilitating communication.

Front

What is the function of the cerebellum?

Back

The cerebellum coordinates voluntary movements, balance, and posture.
