Brain Anatomy
This part of the brain connects the higher and lower neural centers. It consists of the midbrain, pons, and medulla oblongata.
What is the brain stem?
This cranial nerve is responsible for eye movement.
What is CN III (oculomotor)?
This system works with the prefrontal lobes to make us aware of our emotions.
What is the limbic system?
This tough outer layer of the meninges is the strongest and provides protection for the CNS.
What is the dura mater?
This disease is thought to result from the degeneration of the substantia nigra.
What is Parkinson's disease?
These paired protrusions in the midbrain include the superior and inferior colliculi.
What is the corpora quadrigemina?
This nerve has both sensory and motor functions in the face.
What is CN V (trigeminal)?
This area of the brain plays a major role in balance and processes input from the cortex, brain stem, and sensory receptors.
What is the cerebellum?
What is the arachnoid mater?
This type of seizure is characterized by convulsions, muscle rigidity, and loss of consciousness.
What is a tonic-clonic seizure?
This treelike structure in the cerebellum is formed by white matter and helps coordinate movement.
What is the arbor vitae?
This nerve helps maintain equilibrium.
What is CN VII (vestibulocochlear)?
This part of the limbic system is responsible for the fear response.
What is the amygdala?
What is the choroid plexus?
This condition occurs when blood flow to a part of the brain is disrupted, resulting in dead brain tissue.
What is a cerebrovascular accident (CVA) or stroke?
This channel runs through the midbrain and connects the third and fourth ventricles.
What is the cerebral aqueduct?
This nerve originates in the pons and controls facial expressions.
What is CN VII (facial)?
These brain waves are commonly seen during deep restorative sleep (NREM stage 3).
What are delta waves?
This structure consists of tightly packed cells that prevent harmful substances from entering the brain tissue from the blood.
What is the blood-brain barrier (tight junctions)?
These electrical activity patterns are used to diagnose epilepsy and other brain disorders.
What is an electroencephalogram (EEG)?
These three paired fiber tracts connect the cerebellum to the brain stem.
What are the cerebellar peduncles?
This nerve is responsible for controlling many involuntary actions, such as digestion, blood pressure, and respiration.
What is CN X (vagus)?
This helps to protect the brain by reducing its weight so that it is not crushed by its own gravity.
What is cerebrospinal fluid (CSF)?
This inflammation of the meninges can lead to encephalitis if it spreads to the brain.
What is meningitis?
This genetic disorder causes uncontrolled neuron firings that lead to seizures.
What is epilepsy?
