Circumferential
Definition:
(a.) Pertaining to the circumference; encompassing; encircling; circuitous.

(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.
(19) Endoscopic laser therapy is concluded to provide rapid, safe and excellent control of local symptoms in most patients with inoperable colorectal carcinoma, to be less useful when the tumour is large and circumferential and not effective in patients with incontinence.
(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.
Surrounding
Definition:
(p. pr. & vb. n.) of Surround
(a.) Inclosing; encircling.
(n.) An encompassing.
(n.) The things which surround or environ; external or attending circumstances or conditions.
Example Sentences:
(1) Such was the mystique surrounding Rumsfeld's standing that an aide sought to clarify that he didn't stand all the time, like a horse.
(2) The lesion (10.6 X 9.8 mm) was a well-defined ellipsoid granuloma due to a foreign body with a central zone of necrosis surrounded entirely by a fibrous wall.
(3) It was hypothesized that compensatory restraining influences of surrounding soft tissues prevented a more severe facial malformation from occurring.
(4) Their receptive fields comprise a temporally and spatially linear mechanism (center plus antagonistic surround) that responds to relatively low spatial frequency stimuli, and a temporally nonlinear mechanism, coextensive with the linear mechanism, that--though broad in extent--responds best to high spatial-frequency stimuli.
(5) "I was eight in 1983, but I remember a plane that flew low over our Bulawayo suburb and army loud-hailers screaming: 'You are surrounded.'
(6) The usefulness of the proposed method is obvious in cases where the composition of a precipitate on LM scale is to be compared with the LM appearance of the surrounding tissue.
(7) Degraded visual acuity had a significant effect on cadence, foot placement, and foot clearance, but visual surround conditions did not.
(8) Computed tomography does not allow differentiation between these lesions and surrounding normal tissues.
(9) The efficacy of the process is dependent on immersion medium, while the degree of surrounding tissue damage is dependent on energy dose.
(10) In cat, DARPP-32-immunoreactive cell bodies identified as Müller cells were demonstrated in the inner nuclear layer (INL) with processes closely surrounding the cell soma of photoreceptors in the outer nuclear layer.
(11) In the univariate life-table analysis, recurrence-free survival was significantly related to age, pTNM category, tumour size, presence of certain growth patterns, tumour necrosis, tumour infiltration in surrounding thyroid tissue and thyroid gland capsule, lymph node metastases, presence of extra-nodal tumour growth and number of positive lymph nodes, whereas only tumour diameter, thyroid gland capsular infiltration and presence of extra-nodal tumour growth remained as significant prognostic factors in the multivariate analysis.
(12) Surrounding intact ipsilateral structures are more important for the recovery of some of the language functions, such as motor output and phonemic assembly, than homologous contralateral structures.
(13) The dual-probe system incorporates a central collimated probe for monitoring activity in the LV surrounded by an annular detector collimated in such a manner as to provide simultaneous real-time monitoring of the LV background activity.
(14) This technique is sensitive to the optical anisotropy within the muscle, including that due to intrinsic properties of the protein molecules as well as that due to the regular arrangement of proteins in the surrounding medium.
