Ancestral


Definition:

  • (a.) Of, pertaining to, derived from, or possessed by, an ancestor or ancestors; as, an ancestral estate.

  • (15) Although most studies emphasise the similarity of the australopithecines to modern man, and suggest, therefore, that these creatures were bipedal tool-makers at least one form of which (Australopithecus africanus--"Homo habilis", "Homo africanus") was almost directly ancestral to man, a series of multivariate statistical studies of various postcranial fragments suggests other conclusions.
  • (16) The conservation of genomic organization, together with the high sequence homology, indicates that the mouse H+,K(+)-ATPase beta and Na+,K(+)-ATPase beta 2 subunit genes originated from a common ancestral gene.

  • (20) Our findings substantially increase the evidence indicative of a human-chimpanzee-gorilla clade with ancestral separations around 8 to 6 Myr ago.

Collateral


Definition:

  • (a.) Coming from, being on, or directed toward, the side; as, collateral pressure.
  • (a.) Acting in an indirect way.
  • (a.) Related to, but not strictly a part of, the main thing or matter under consideration; hence, subordinate; not chief or principal; as, collateral interest; collateral issues.
  • (a.) Tending toward the same conclusion or result as something else; additional; as, collateral evidence.
  • (a.) Descending from the same stock or ancestor, but not in the same line or branch or one from the other; -- opposed to lineal.
  • (n.) A collateral relative.
  • (n.) Collateral security; that which is pledged or deposited as collateral security.

Example Sentences:

  • (1) It also provides mechanical support for the collateral ligaments during valgus or varus stress of the knee.
  • (2) 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.

  • (4) In addition to terminating at the brachial segments, they had one to three collaterals to the upper cervical cord (C3-C4), where the propriospinal neurons projecting to forelimb motoneurons are located.
  • (5) The relationship between pressure at the functional site of origin of intracranial collateral channels (Pstem) and systemic pressure allows an estimation of the size of vascular channels from which collateral vessels originate.
  • (6) The diagnosis of an arterial injury may be readily apparent, but the excellent upper-extremity collateral circulation may create palpable distal pulses despite a significant proximal arterial injury.
  • (7) When collateral marginal vessels were eliminated, adjacent arterial blood flow decreased to control levels and venous flow virtually stopped.
  • (8) Systemic collateral arteries were present in all 38 patients.
  • (9) The data reported here, in combination with the published literature, suggest that the collaterals of roughly 300 G hair fibers overlap at any given point at middle levels of the cuneate nucleus.
