What is mild focal stenosis?
There are two types of stenosis. One is in an artery and the second is in the vertebral canal. The term focal means that this narrowing is not large or lengthy. If it is in the vertebral canal, there can be no symptoms at all or mild ones. If in the artery, there's more concern because this narrowing can cause lack of oxygen and nutrients to get to the area the artery is going. There is surgical treatment for both.
What can happen from having an enlarged vertebral artery?
The vertebral artery carries blood from the heart to the brain. An enlarged vertebral artery is usually caused by an accumulation of plaque that narrows the amount of blood flow to the brain causing memory loss or dizziness. An enlarged vertebral artery can also cause a sense of fullness near the ear, feels like water lodged in the canal.

Is the jugular foramen larger then the carotid canal?
No, the carotid canal is larger than the jugular foramen in the human skull. The carotid canal transmits the internal carotid artery, while the jugular foramen transmits the internal jugular vein and cranial nerves.
What passes through the carotid canal?
spinal cord
Which bony foramen does the internal carotid artery run through?
The carotid canal. When viewed from a superior angle, the internal carotid may appear to be transmitted through the foramen lacerum; however, it is not. The foramen lucerum is actually covered by connective tissue and transmits NO vessels or nerves. Though there are many hypotheses as to the purpose of the foramen lucerum, there is no definitive answer.
What structures pass through the foramen ovale of sphenoid?
(From Wikipedia)The internal carotid artery passes superiorly from the carotid canal in the base of the skull, emerging via that part of the foramen lacerum which is not occluded by cartilage.The artery of pterygoid canal, the nerve of pterygoid canal and some venous drainage also pass through the foramen lacerum.The nerve of pterygoid canal comprises the deep petrosal nerve and the greater petrosal nerve the former carrying sympathetic fibres and the latter parasympathetic fibres of the autonomic nervous system to blood vessels, mucous membranes, salivary glands, and lacrimal glands.Furthermore, one of the terminal branches of the ascending pharyngeal artery (itself a branch of the external carotid artery) passes through the foramen lacerum. The ascending pharyngeal artery is one of three possible "meningeal branches" of this vessel.Lastly, some emissary veins pass through the foramen lacerum. These connect the extracranial pterygoid plexus with the intracranial cavernous sinus and present an unopposed route for infection.
What is an alar canal?
An alar canal is a bony tunnel through the basisphenoid bone of the skull, through which the maxillary artery and nerve pass.
Site of jugular foramen and carotid canal?
The jugular foramen is located at the base of the skull, between the occipital and temporal bones, posterior to the carotid canal. The carotid canal is situated in the petrous part of the temporal bone, just above the jugular foramen.
What is the function of vertebrarterial canal?
to allow the vertebral artery to pass through to the brain
What is an alar foramen?
An alar foramen is the opening at either end of the alar canal, the bony canal through the basisphenoid bone of the skull, through which the maxillary artery and nerve run.
What structure pass through the adductor subsartorial canal?
