accessory meningeal artery

An artery that branches from the maxillary artery and supplies the meninges. The accessory meningeal artery ascends through the foramen ovale to enter the cranial cavity and supply the dura mater of the floor of the middle cranial fossa and of the trigeminal cave, and to the trigeminal ganglion.

अक्सर पूछे जाने वाले प्रश्न

What is the accessory meningeal artery?
The accessory meningeal artery is a branch of the maxillary artery that ascends through the foramen ovale to enter the cranial cavity. It supplies the meninges, particularly the dura mater of the floor of the middle cranial fossa and the trigeminal cave, as well as the trigeminal ganglion.
Where is the accessory meningeal artery located?
The accessory meningeal artery originates from the maxillary artery in the infratemporal fossa and passes superiorly through the foramen ovale, an opening in the greater wing of the sphenoid bone. Once inside the skull, it distributes to the dura mater of the middle cranial fossa.
What is the function of the accessory meningeal artery?
The accessory meningeal artery provides blood supply to the dura mater of the floor of the middle cranial fossa, the trigeminal cave (Meckel's cave), and the trigeminal ganglion. It is a supplemental meningeal artery alongside the larger middle meningeal artery.
What conditions may be associated with the accessory meningeal artery?
The accessory meningeal artery may be relevant in the context of intracranial vascular anatomy, trigeminal neurovascular relationships, and surgical approaches to the middle cranial fossa or foramen ovale. Clinical evaluation is necessary for any suspected condition involving this vessel.
How is the accessory meningeal artery examined?
The accessory meningeal artery may be visualized using CT angiography, conventional cerebral angiography, or MR angiography when detailed mapping of meningeal vasculature is required. It is also encountered during neurosurgical procedures in the middle cranial fossa region.
