Nervous System Flashcard 1

Front

What is an AVM (Arteriovenous Malformation)?

Back

An AVM is a tangle of abnormal blood vessels connecting arteries and veins, which can lead to rupture and bleeding.

Front

What is anosmia?

Back

Anosmia is the loss of the sense of smell, which can affect taste and the ability to detect scents.

Front

Which cranial nerve is responsible for the sense of smell?

Back

The Olfactory nerve (Cranial Nerve I) is responsible for the sense of smell.

Front

What does the NIH Stroke Scale measure?

Back

The NIH Stroke Scale is used to assess the severity of a stroke.

Front

Which lobe of the brain is primarily responsible for visual processing?

Back

The Occipital lobe is primarily responsible for visual processing.

Front

What is depolarization in the context of action potentials?

Back

Depolarization is the process during an action potential when the membrane potential becomes less negative, allowing the neuron to fire.

Front

What is the function of the Trochlear nerve?

Back

The Trochlear nerve (Cranial Nerve IV) controls the superior oblique muscle of the eye, which is responsible for downward and lateral movement.

Front

What is the role of the Abducens nerve?

Back

The Abducens nerve (Cranial Nerve VI) controls the lateral rectus muscle, allowing for lateral eye movement.

Front

What is a hemorrhagic stroke?

Back

A hemorrhagic stroke occurs when a blood vessel in the brain ruptures, leading to bleeding in or around the brain.

Front

What is ischemic stroke?

Back

An ischemic stroke occurs when a blood vessel supplying blood to the brain is obstructed, often due to a clot.
