Neuro Topography

The topography of the brain (quiz 3)

QuestionAnswer
The general location of the medulla Extends from the spinal cord to the pons
How is the medulla connected to the cerebellum? By the inferior cerebellar peduncles
What is the closed part of the medulla? The elongation of the central canal of the spinal cord.
What is the open medulla? The rostral half of the medulla
Where is the pons? Extends from the medulla to the midbrain.
How is the pons connected to the cerbellum? By the middle cerebellar peduncles.
Where does the midbrain lie? Between the pons and the forebrain, in the tentorial notch.
Cerbral aqueduct The narrow channel that is the only route by which CSF can exit the ventricles of the forebrain to the fourth ventricle.
The anterior part of the midbrain The cerebral peduncle.
The posterior part of the midbrain The tectum.
The pyramids A pair of elongated elecations of either side of the anterior median fissure of the medulla.
The Olive A prominent elevation, lateral to the rostral part of each pyramid of the medulla.
Preolivary sulcus a shallow groove between the olive and the pyramid of the medulla.
Postolivary sulcus The sulcus posterior to the olive.
The nerve rootles of what nerve(s) attach in the postolivary sulcus? Glossopharyngeal (IX) and Vagus (X)
Where do the the cranial rootlets of the accessory (XI) nerve emerge? In line with vagus, but inferior to the postolivary sulcus.
What is the anterior portion of the pons called? Basilar part
What usually occupies the shallow basilar sulcus near the midline? Basilar artery.
Where does the abducens (VI) nerve emerge? The pontomedullary junction, near the lateral border of the pyramid.
What nerve(s) emerge from the more lateral part of the pontomedullary junction? Facial (VII) and Vestibulocochlear (VIII)
Where does the trigeminal (V) nerve emerge? On the anterolateral surface of the pons about midway between the medulla and the midbrain.
What forms the anterior surface of the midbrain? The cerebral peduncles.
What are the cerebral peduncles made of? Converging crura.
What seperates the cerebral crura? The interpeduncular fossa
What emerges from the wall of the interpeduncular fossa? The oculomotor (III) nerve.
Where is the posterior median sulcus? On the closed medulla.
What is on either side of the posterior median sulcus? The gracile tubercles
Location of the cuneate tubercle Lateral to each gracile tubercles
Obex Caudal tip of the fourth ventricle, lies betwet the gracile tubercles.
Striae medullares white strands in the medullary floor of the fourth ventricle. Extend laterally from the median sulcus towards the lateral recess.
What divides the floor of the fourth ventricle into symmetric halves? The median sulcus
Superior foveae a small depression at the pontine level
Inferior foveae a small depression at the medullary level
Extends laterally from the two fovea of the fourth ventricle, to the lateral recess Vestibular area
Small eminence of the vestibular area at the lateral recess Acoustic tubercle
Medially between the inferior fovea and the median sulcus Hypoglossal trigone
Laterally between the inferior fovea and the median sulcus Vagal trigone
Structure between the spuerior fovea and the median sulcus. Medial eminence
Structure continuous with basilar part of the pons. Middle cerebellar peduncle (brachium pontis)
Structure which connects the medulla to the cerebellum. The inferior cerebellar peduncle (restiform body)
Structure that passes from the roof of the fourth ventricle into the tegmentum of the rostral pons. Superior cerebellar peduncle (brachium conjuctivum
Posterior surface of the midbrain. The tectum
Two pairs of mounds of the tectum corpora quadrigemina or inferior and superior colliculi
Trochlear nerve (IV) emerges caudal to the inferior colliculi.
Small area caudal to the superior colliculi Pretectum

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
