Study Notes
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.
