The accessory meningeal artery (also accessory branch of middle meningeal artery, pterygomeningeal artery, small meningeal or parvidural branch) is a branch of the maxillary artery that 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 (representing the main ...
In dental anatomy, the apical foramen, literally translated "small opening of the apex," is the tooth's natural opening, found at the root's very tip—that is, the root apex — whereby an artery, vein, and nerve enter the tooth and commingle with the tooth's internal soft tissue, called pulp.
In the jugular foramen, it receives one or two filaments from the cranial part of the nerve, or else joins it for a short distance and then separates from it again. As it exits from the jugular foramen, it runs backward in front of the internal jugular vein in 66.6% of cases, and behind it in 33% of cases.
The lesser palatine canals start from the greater palatine canal, and run with them, also opening into the roof of the oral cavity.Their openings are known as the lesser palatine foramina, and they transmit the lesser palatine artery, vein, and nerve, as well as the middle palatine vessels and nerve.
Intervertebral foramen, foramina formed between vertebrae; Lesser sciatic foramen, an opening between the pelvis and the posterior thigh; Obturator foramen, the opening created by the ischium and pubis bones of the pelvis; Vertebral foramen, the foramen formed by the anterior segment (the body), and the posterior part, the vertebral arch
After branching off the maxillary artery in the infratemporal fossa, it runs through the foramen spinosum to supply the dura mater (the outer meningeal layer) and the calvaria. The middle meningeal artery is the largest of the three (paired) arteries that supply the meninges, the others being the anterior meningeal artery and the posterior ...

Specific to the cervical vertebra is the transverse foramen (also known as foramen transversarium). This is an opening on each of the transverse processes which gives passage to the vertebral artery and vein and a sympathetic nerve plexus. On the cervical vertebrae other than the atlas, the anterior and posterior tubercles are on either side of ...
