Foramen [noun]

It is remarkable that neither of these observers should have noticed the foramen in the testa.

In Eutamias townsendii, however, the infraorbital foramen is rounded as much as in the subgenus Eutamias and in the genus Tamias.

The foramen magnum, occipital condyles, and exoccipitals show no unusual features.

The ductus arteriosus closes up about the same time as the foramen ovale.

This is owing to the foramen ovale being very open and closing slowly.

Probably not; and more especially if it is a lumbar artery, and injured in the foramen through which it passes from the vertebra.

It is formed from two centres, each of which is originally a ring round the carotid foramen.

The three component bones meet in the circular pneumatic foramen in the middle of the under side of the distal carpal.

A small foramen exists at the mid-length of the tibio-fibula.

Foramen single, alternating above and below in adjoining partitions.
