Medulla Oblongata Anatomy

Brain Structures

• The external surface of the medulla oblongata has a synonym called Myencephalon.
• The accessory nerve via jugular foramen is found in the medulla oblongata.
• The anterior median fissure is a synonym for desiccation of the cross section of the pyramid.

Medulla Oblongata

• The rhomboid fossa is located on the anterolateral surface of the medulla oblongata.
• The pineal recess (posterior wall of the 3rd ventricle) is not found in the rhomboid fossa.
• Obex is not in the 4th ventricle.
• The hypoglossal nerve comes out of the anterolateral fissure of the medulla oblongata.

4th Ventricle

• Monroe is not in the 4th ventricle.
• Locus coeruleus is visible in the pons.
• The 4th ventricle does not produce cerebrospinal fluid.

Cerebrospinal Fluid Circulation

• Cerebrospinal fluid circulates through the lateral ventricle, third ventricle, cerebral aqueduct, and fourth ventricle.

Forebrain

• Diencephalon belongs to the forebrain.
• The thalamic wall has an inferior wall called ventricular.
• Infundibulum is a part of the diencephalon.

Midbrain

• The superior colliculus forms part of the midbrain.
• Substantia nigra belongs to the midbrain.

Diencephalon

• Posterior perforating substance is located in the diencephalon.
• Metathalamus has a posterior commissure.

Basal Ganglia

• External capsule separates the claustrum and putamen.
• Thalamus is not an example of basal ganglia.
• Nucleus accumbens (created by caudate and putamen) is located in the ventral stratum.

Lateral Ventricle

• The caudate is not found in the posterior cord of the lateral ventricle.

Cerebellum

• The superior cerebellum is connected to the midbrain.
• The cerebellum is supplied by the anterior inferior cerebellar artery, a branch of the basilar artery.
• The basilar cerebellar artery arises from the union of 2 vestibular arteries.

4th Ventricle Walls

• The anterior wall of the 4th ventricle is formed by the rhomboid fossa.

Blood Vessels

• The great cerebral vein drains into the straight sinus.
• The internal carotid artery gives off the middle cerebral artery.

Other Structures

• Insula is located in the cortex covered by the temporal lobe.
• Calcar Avis is located in the medial horn of the posterior cord.
• Caudate nucleus is close to the anterior horn of the lateral ventricle.
