(17) Although most filaments were outside the circumferential band of microtubules and the cisternae of the open canalicular system, individual filaments dipped down into the cytoplasm and were found between the microtubules and in association with other membranes.
(18) Intraoperative end-systolic meridional and circumferential stresses fell significantly in patients with aortic stenosis but remained unchanged in those with aortic regurgitation.

(20) By 15 days, a dense accumulation of blastema cells is present beneath the apical cap, and these cells are preferentially oriented in a circumferential direction.
Encircle
Definition:
(v. t.) To form a circle about; to inclose within a circle or ring; to surround; as, to encircle one in the arms; the army encircled the city.
Example Sentences:

(2) More distally the nerve fibres consist only of one axon encircled by a Schwann cell.
(3) Foveal involvement included coarse foveal granularity, thinning of the foveal retinal pigment epithelium, increasing encirclement of the fovea with focal areas of atrophy, and minimal macular drusen.
(4) The roentgenographic appearance of most lesions consisted of a radiolucent central nidus encircled by sclerotic bone.
(5) At the ultrastructural level, kynurenine aminotransferase immunoreactive astrocytic processes were apparent throughout the neuropil where they often encircled capillaries and surrounded axospinous synapses.
(6) The bands encircle the muscle fiber perpendicular to the long axis of the fiber and they matched the sites of attachment of the sarcomeres to the plasma membrane.
(7) These and other results indicate that the junctional complex encircling the apical surface of a sheet of MDCK cells can provide an effective permeability barrier constituting a true occluding junction with the same properties in hemicyst and nonhemicyst areas.

(9) The nerve bundles, encircled by basal lamina, were enclosed by a thin connective tissue layer and by flattened fibroblast-like cells.
(10) Within these fields, the development of perineuronal baskets followed a similar medial to lateral sequence: DA axons first surrounded a few neuronal cell bodies at P3 in the medial part of the intermediate LSN; at P6, Met-IR axons encircled more laterally located perikarya, and only at P9, some neurons located along the ventricle in the lateral DA field became surrounded.
