| law of polar excitation | A given segment of a nerve is irritated by the development of catelectrotonus and the disappearance of anelectrotonus, but the reverse does not hold; i.e., excitation occurs at the cathode when the circuit is closed and at the anode when it is opened. Synonym: Pfluger's law. (05 Mar 2000) |
| anastomotic branch of middle meningeal artery to lacrimal artery | <anatomy, artery> A branch of the middle meningeal artery arising in the cranial cavity which runs anteriorly through the superior orbital fissure to anastomose with the lacrimal artery. See: orbital branch of middle meningeal artery. Synonym: ramus anastomoticus arteriae meningeae mediae cum lacrimali. (05 Mar 2000) |

| blind foramen of frontal bone | <anatomy> Blind or caecal foramen of the frontal bone; the blind foramen formed immediately anterior to the crista galli by a notch at the lower end of the frontal crest and its articulation with the ethmoid bone. It is insignificant postnatally, but gives passage to vessels during development. Synonym: foramen caecum ossis frontalis, blind foramen of frontal bone, caecal foramen of frontal bone.
