The pontine nuclei are located within the basilar pons. Also nearby are the raphe nuclei and the locus coeruleus, nuclei of cranial nerves 9-12, and the dorsal respiratory group, which are located further caudally in the brainstem. The dorsal respiratory group are connected to the pneumotaxic and apneustic centres of the pontine tegmentum.
Lateral pontine syndrome, also known as Marie-Foix syndrome or Marie-Foix-Alajouanine syndrome [1] is one of the brainstem stroke syndromes of the lateral aspect of the pons. A lateral pontine syndrome is a lesion which is similar to the lateral medullary syndrome, but because it occurs in the pons, it also involves the cranial nerve nuclei of ...
Medial inferior pontine syndrome is a condition associated with a contralateral hemiplegia. [ citation needed ] "Medial inferior pontine syndrome" has been described as equivalent to Foville's syndrome .
The basilar part of pons, also known as basis pontis, or basilar pons, is the ventral part of the pons (ventral pons) in the brainstem; the dorsal part (dorsal pons) is known as the pontine tegmentum. The basilar part of the pons makes up two thirds of the pons. [1] It has a ridged appearance with a shallow groove at the midline.
The superior pontine sulcus separates the pons from the midbrain. [7] Posteriorly, the pons curves on either side into a middle cerebellar peduncle. [4] A cross-section of the pons divides it into a ventral and a dorsal area. The ventral pons is known as the basilar part, and the dorsal pons is known as the pontine tegmentum. [3]
In children, the most common cause is a stroke of the ventral pons. [9]Unlike persistent vegetative state, in which the upper portions of the brain are damaged and the lower portions are spared, locked-in syndrome is essentially the opposite, caused by damage to specific portions of the lower brain and brainstem, with no damage to the upper brain.
The region includes the tegmentum, crus cerebri and pretectum. By this definition, the cerebral peduncles are also known as the basis pedunculi, while the large ventral bundle of efferent fibers is referred to as the cerebral crus (crus means ‘leg’ in Latin.) or the pes pedunculi (pes means 'foot' in Latin.).
The central tegmental tract is a tract that carries ascending and descending fibers, situated in the midbrain tegmentum, and the pontine tegmentum. The tract is situated in the central portion of the reticular formation .
