The pontine arteries are a number of small arteries which come off at right angles from either side of the basilar artery and supply the pons and adjacent parts of the brain. The pontine arteries include the paramedian arteries, the short circumferential, and the long circumferential arteries. [1] [a]
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. This groove is the basilar sulcus and is covered by the basilar artery. [2] The basilar artery feeds into the circle of Willis providing blood supply to the brainstem and cerebellum. [3]
The ventral pons is known as the basilar part, and the dorsal pons is known as the pontine tegmentum. [3] The ventral aspect of the pons faces the clivus, with the pontine cistern intervening between the two structures. The ventral surface of the pons features a midline basilar sulcus along which the basilar artery may or may not
The prepontine cistern, or pontine cistern is one of the subarachnoid cisterns situated ventral to the pons. [1] It contains the basilar artery . [ 2 ] : 478 Each lateral aperture opens into the pontine cistern just posterior to the cranial nerve VIII .
The pontine tegmentum, or dorsal pons, is the dorsal part of the pons located within the brainstem. The ventral part or ventral pons is known as the basilar part of the pons, or basilar pons. Along with the dorsal surface of the medulla oblongata, it forms part of the rhomboid fossa – the floor of the fourth ventricle.
"Studies show that our hippocampus, the part of the brain that is responsible for memory function, receives increased blood flow and oxygenation when we engage in regular physical exercise.
The middle cerebellar peduncle is the largest of the three cerebellar peduncles. It connects the pons and cerebellum.It consists almost entirely of fibers passing from the pons to the cerebellum (fibrocerebellar fibers); the fibers arise from the pontine nuclei and decussate within the pons before entering the peduncle [1] to end in the contralateral cerebellar hemisphere.
Health officials in Europe are investigating Ozempic and the trendy drug’s possible link to an eye-rotting condition that causes blindness. On Dec. 17, the European Medicines Agency announced ...
