Example Sentences:

(11) Within 4-12 weeks there appeared deformity, sharp sinuosity, disorders in usual orientation of vessels.
(12) Alterations in the afferent innervation were manifested in the increased sinuosity of fibers, areas of hyper- and hypoimpregnation, appearance of thickenings in the fibers.
Sinuous
Definition:
(a.) Bending in and out; of a serpentine or undulating form; winding; crooked.
Example Sentences:
(1) The astrocytes had generally two types of processes: (1) thread-like processes of relatively constant width with few ramifications and few lamellar appendages and (2) the sinuous processes with clusters of lamellar appendages.
(2) In the intercellular space long and smooth septa are clustered in sinuous strands and intramembrane particles appear on the PF.
(3) According to observations carried out in ovo and after fixation, morphological modifications are demonstrated in the developing vasculature of the heparin-treated CAMs which, compared with the control CAMs, show dilated and sinuous arterial and venous branches, denser and irregular capillary networks, and a high number of vascular primordia.
(4) This structure contains cells with single or double nuclei, round or oval in shape, surrounded by a light halo, with scattered chromatin and a well-defined nucleolus, acidophilic cytoplasm containing, in comparison with the common myocardium, few sinuous myofibrils with transverse striations and a larger amount of glycogen.
(5) The sinuous processes rich in lamellae were predominant in protoplasmic astrocytes, and clearly corresponded to the sheet- or veil-like processes of Golgi-impregnated astrocytes.
(6) In the heart of the dog five types of thebesian veins were served: arboriform, sinuous, brush-like, canaliculated and stellate.
(7) Using cetylpyridinium chloride (CPC) in glutaraldehyde as fixative, we observed sinuous fiber-like structures 300-500 nm long and 7-14 nm thick in the spaces between the collagen fibers of rat incisor predentin.
(8) Some PtK-2 cells have straight stress fibers which stained with anti-actin, but in confluent cultures all PtK-2 cells have, instead, sinuous phase-dense fibers which stained with antibody.
(9) Finally, three XN-cells were intrageniculate interneurons, which possessed small somata (mean soma size = 174 micron2), fine sinuous dendrites covered with beadlike varicosities on stalked appendages, and no obvious axon.
(10) This layer is characterized by flattened cells with sinuous processes, extracellular spaces containing an amorphous material, and the presence of junctions between its cells.
(11) The Four,” as they came to be called, created in the mid-nineties their own highly individual interpretation of the new art, subsequently dubbed “the Glasgow Style.” They liked sinuous, elongated animal-vegetable forms with a strong vertical emphasis in their overall design; the human figure, too, was stylised almost beyond recognition.
(12) Its cell body is usually found in the inner half of the SG layer and its sinuous dendrites cross the SG layer and enter the marginal layer.
(13) Arterial angiography identifies polyaneurysmal dystrophy; in the context of a twisted and sinuous system of large arteries, multiple spindle-shaped aneurysms can be distinguished which are frequently bilateral and symmetrical.
(14) In the ALD intestinal epithelium, DAB+ material was also seen in long, sinuous, tubular or cisternal elements intermingled and occasionally in continuity with peroxisomes.
(15) The mantle dentin contains sinuous tubules with a type I arrangement of SIAR classification (1986).

(17) In the cervical enlargement of the rat spinal cord, fluoride-resistant acid phosphatase (FRAP) occurs in most of the small dark sinuous primary afferent central terminals (CI-terminals) of type I-synaptic glomeruli of lamina II and is lacking in the large light roundish primary afferent CII-terminals of type II-glomeruli.
(18) Degeneration of the tactile cells in epithelium of the cat sinuous hairs after sectioning the infraorbital nerve manifests itself as cytoplasmic vacuolization and induration with electron opaque bodies in it, changes in nuclear configuration and in chromatin density.
(19) The cytoplasm of macrophages gives only short, somewhat sinuous processes.
(20) Selective arteriography of the coeliac trunk showed extremely sinuous intra-hepatic arteries in 3 of these cases, and obstruction of the portal vein, in one case.
