What's the difference between orbit and postorbital?

Orbit


Definition:

  • (n.) The path described by a heavenly body in its periodical revolution around another body; as, the orbit of Jupiter, of the earth, of the moon.
  • (n.) An orb or ball.
  • (n.) The cavity or socket of the skull in which the eye and its appendages are situated.
  • (n.) The skin which surrounds the eye of a bird.

Example Sentences:

  • (1) Furthermore echography revealed a collateral subperiosteal edema and a moderate thickening of extraocular muscles and bone periostitis, a massive swelling of muscles and bone defects in subperiosteal abscesses as well as encapsulated abscesses of the orbit and a concomitant retrobulbar neuritis in orbital cellulitis.

  • (8) In several other cases, MR provided information beyond that obtained with CT. MR has the advantage of providing exquisite anatomic detail in multiplanar images, and it appears to be more sensitive than CT in detecting small, subacute and chronic hemorrhage within soft-tissue masses in the orbit and in detecting ischemia of the globe.

  • (19) Follow up consisted of clinical investigation, laboratory evaluation with detailed thyroid function tests and complete ophthalmological assessments including A and B scan ultrasound and computerized tomography (CT) of the orbits.
  • (20) The advances in lid and orbital surgery are due to the improvements made in diagnostic equipment and to technical refinements.

Postorbital


Definition:

  • (a.) Situated behind the orbit; as, the postorbital scales of some fishes and reptiles.
  • (n.) A postorbital bone or scale.

Example Sentences:

  • (1) Mediolateral postorbital bar width and (to a lesser degree) browridge height are correlated with neurofacial torsion during mastication and variation in masticatory muscle size.
  • (2) The known Cretaceous and Paleocene primates, the Paromomyiformes, although lacking a fully developed postorbital bar, are nevertheless, both cladistically and phenetically, closest to the common ancestor of the living primates.
  • (3) From the above "Bauplan" of the neurocranium, the following conclusions can be drawn: (1) the simple homology of the reptilian and placental mammalian pila metoptica is questionable; (2) the pila antotica is produced by the absorption of the mid-dorsal part of the postorbital cartilage, while the dorsum sellae in mammals is produce by the chondrification of the middle part of the same anlage; (3) homology of the ala hypochiasmatica in mammals with the supratrabecular cartilage in reptiles is more feasible than with the cartilago hypochiasmatica; and (4) the crista sellaris in reptiles is not a part of the primary cranial wall but probably of secondary production.
  • (4) The postorbital plate of Tarsius is formed by frontal and alisphenoid flanges that extend laterally from the braincase to the zygomatic's frontal process, which is not broader than the postorbital bars of other prosimians.
  • (5) In pigs the zygomatico-squamosal suture has a short vertical segment located within the postorbital process and a longer horizontal segment which extends posteriorly.
  • (6) The postorbital technique is a new surgical approach to the middle cerebral artery that leaves the intraorbital structures intact.
  • (7) After resection of the postorbital processes and gentle retraction of the eye, the optic foramen is approached with the help of an operating microscope.
  • (8) It is postulated that the flexibility of the rostrum acts to absorb shock and it is suggested that the primate postorbital bar is developed in response to craniofacial morphology which increases compressive bite forces.
  • (9) The anterior lateral line is composed of a series of cranial canals; the supraorbital-postorbital canal; the suborbital canal; and the preopercular-mandibular canal which extends along the lower jaw.
  • (10) Dimensions of the supraorbital torus, postorbital bar, and postorbital septum were collected in an ontogenetic series of Macaca fascicularis and compared with expectations based on models that attribute morphological variation in these features to spatial factors, allometry, anterior dental loading, and neurofacial torsion.
