The foramen lacerum is primarily traversed by the greater petrosal nerve, a branch of the facial nerve (CN VII). While no major vessels pass through the foramen itself, the area is adjacent to the internal carotid artery, and the greater petrosal nerve exits the skull through the foramen lacerum, contributing to the formation of the nerve of the pterygoid canal.

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.
Which nerves pass through the jugular foramen?

What passes through the foramen ovale?
Sphenoid bone of the skull. It is the most interesting bone in the skull.
Does the optic nerve pass through the foramen ovale?
The natural blind spot (scotoma) is due to lack of receptors (rods or cones) where the optic nerve and blood vessels leave the eye. It is where the optic nerve leaves the retina not enter it. The optic disk or blind spot is where the optic nerve leaves the eye; you cannot use that field of vision because the optic nerve is there.
What passes through the foramen rotundum?
The maxillary nerve (V2) passes through the foramen rotundum, which is a circular opening in the sphenoid bone located in the middle cranial fossa. The maxillary nerve is a branch of the trigeminal nerve (V).

Glossopharyngeal nerve passes through what bones?
The glossopharyngeal nerve (cranial nerve IX) passes through the jugular foramen, which is formed by the temporal and occipital bones of the skull. This foramen also allows the passage of the vagus nerve and the accessory nerve. After exiting the skull, the glossopharyngeal nerve branches out to innervate structures in the throat and tongue.
What does stenosis of the right foramen mean?

What structure passes through the invertebral foramen?
The spinal nerve passes through the intervertebral foramen, which is a small opening formed by two adjacent vertebrae in the spine. The spinal nerve carries sensory and motor information between the spinal cord and the rest of the body.

Does the sciatic nerve pass through the lesser sciatic foeamen?
If you look up the nervous system there are 3 places in your lower back that cause Sciatic or pinched nerve in three locations. Lower lumbar back at 3,4,5, cause pain in the left or right backside cheek, a shorter nerve. One causes pain that comes into the groin are from the backside around and up through groin. One causes the pain that runs down the outside seem of your pants and can end of in the second little toe. (next to the pinkie toe) It is called the Sciatic nerve.
