Notch
Definition:
(n.) A hollow cut in anything; a nick; an indentation.
(n.) A narrow passage between two elevation; a deep, close pass; a defile; as, the notch of a mountain.
(v. t.) To cut or make notches in ; to indent; also, to score by notches; as, to notch a stick.

(7) Radiographic manifestations include endosteal sclerosis of the neurocranium with loss of the diploë, osteosclerosis and hyperostosis of the mandible with absence of the normal antegonial notches, endosteal sclerosis of the diaphyses of long bones (including metacarpals and metatarsals), and osteosclerosis of the pelvis.
(8) For the experimental studies, fractures of the jaw bone in terms of oblique osteotomies from angle to sigmoid notch of the mandible of the Malaysian monkeys were made by using #700 fissure bur and reduced and fixed them in terms of interosseous wiring.
(9) Lymphadenopathies were classified by the criteria proposed by Yoshinaka et al., type I: poorly-defined borders, diffuse internal echoes; type II: well-defined borders, diffuse internal echoes; type III: well-defined borders, notchings, strong internal echoes.
(10) Here, we examine a group of six recessive mutations, the facets (fa, fa3, fag, fag-2, fafx and fasw), which affect eye and optic lobe morphology and have been previously shown to be associated with the insertion of transposable elements into an intronic region of Notch.
(11) Another frequent finding was partial or total obstruction at the tentorial notch, often in combination with reduced or absent activity along the superior sagittal sinus.
