Foramen obturator : Present between the pubis and ischium of pelvic girdle of mammals,
Foramen filum terminale: An opening for the terminal filament of the spinal cord of a vertebrate e.g. in urostyle of frog.
Foramen incisive : Present anteriorly between the palatine processes near the incisor teeth in mammals.
Foramen infraorbital : It lies beneath the orbit in man.
Foramen intervertebral : An opening formed by intervertebral notch in vertebrae through which a spinal nerve makes its exit from the spinal cord.
Foramen Lecerum anterius: Present in the mammalian cranium between the orbitosphenoid and alisphenoid bones making a passage for the occulomotor, trochlear and abducens nerves and the ophthalmic branch of the trigeminal nerve.
Foramen Lacerum medium : An opening in the mammalian skull for the passage of the internal carotid artery between the basisphenoid bone and the tympanic bulla.
Foramen Lacerum Postcrius: An opening in the mammalian skull between the periotic and the exoccipital bones for the passage of the glossopharyngeal, vagus, spinal acccssory nerves and the internal jugular vein.
Foramen magnum : It’s a large opening at the hind end of the skull through which brain comes out as spinal cord.
Foramen of Monro: It’s a passage connecting each cerebral cavity with the third ventricle in the brain of a vertebrate.
Foramen Mental: It’s present in tibio-fibula of frog.
Foramen optic: It’s a round foramen located medially in the orbitosphenoid bone of orbit of vertebrates, which transmits the optic nerve and ophthalmic artery.
Foramen spinosum: Opening in the sphenoid bone of mammalian skull.
Foramen trioesseum: An opening enclosed by the scapula, clavicle and coracoid of a bird at the point where these three bones meet. The tendon of the minor pectoral muscle, which raises the wing, passes through this opening.
Foramen ovale: An embryonic opening in the septum separating the two auricles of the mammalian heart, by which the blood of right auricle can pass directly to the left auricle.
Foramen of rotundum: An opening in the sphenoid bone of mammalian skull through which the maxillary branch of the trigeminal nerve emerges from the brain.
Foramen of Panniazae: A small opening connecting the two systemic aortae of a crocodile or similar reptile at the point just beyond the semilunar valves where the two aortic arches cross one another.
