Denticulate
Definition:
(a.) Alt. of Denticulated
Example Sentences:

(2) The basal ridge has three to five rows of denticulations.
(3) The following features of the lateral corticospinal tract are emphasized in the cervical cord: (1) the large extent of the white matter of the cord covered by the tract, and the anterior extent of the tract, the border being anterior to the central canal; (2) in the lower cervical cord, the separation of fibres from the main mass of the tract, which reach the periphery of the cord in the anterolateral sector; (3) the presence in many cords of the ventral crossed bundle; and (4) the relationship of the denticulate ligament to the tracts in the cervical segments.
(4) Additional evidence on reptiles and birds demonstrates that the marginal neurons are closely associated with the denticulate ligaments.
(5) In the cat somewhat better pronounced denticulations were observed, and the gyrus dentatus was directed from the rostral aspect towards the dorsal and the lateral, and before reaching the splenium corporis callosi it changed its course towards the medial aspect and passed into the tuberculum gyri dentati.
(6) These tumors were restricted to the spinal denticulate ligaments.

(8) Close apposition, or rarely a denticulated surface and lysis of desmosomes were present, both probably indications of cellular interactions.
(9) These nuclei have been examined in snakes, and it has become apparent that the denticulate ligament is both structurally and functionally closely related to the marginal nuclei.
(10) By means of an appropriate sequence of transections of nerve roots and denticulate ligaments within the dura, and transections of the dural sheaths and nerves outside the dura, the strain on the dura was found to be imposed by the attachments of the dural nerve sheaths from T-6 to S-7.
(11) The structure of the denticulate ligaments, similar in the three different amphibians, was composed of collagen, elastin, and fibroblasts, all of which were concentrated in the segmental lateral processes.
(12) Both pia and denticulate ligaments were moderately elastic, but the spinal cord substance showed an upward curve, which indicated a predominantly viscous character.
(13) It is argued that both these findings are explicable on the theory that mechanical stresses play a part in determining the site of lesions; that such stresses are commonly transmitted to the cord via the denticulate ligaments during flexion of the spine; and that many of the lesions are attributable to vascular leakages due to tension in the denticulate ligaments.
(14) Its surface is almost flat with very poor denticulations, and below the splenium corporis callosi it forms the tuberculum gyri dentati which is wider than the splenium.
