(1) The nucleus eventually no longer acts hydrostatically, thus the annulus and endplate are exposed to high point stresses which might lead to the cracks and fissures seen in degenerate discs.(2) It is possible that the ligamenta flava provide some resistance to flexion and so, like the posterior longitudinal ligament, protect the posterior annulus .(3) The cells of the outer annulus are thin and extended along the collagen fibrils, rather like tendon cells.(4) Under these circumstances neither the annulus nor the lipid membrane will be situated symmetrically around the edges of the orifice.(5) The tympanic annulus must be completely visible.(6) No defect was detected in the relocation of the paired centrioles to abut the nuclear membrane or in the initial formation of the annulus .(7) A beamsplitter mixes the returning measurement beam with the collimated local beam; the inner core component is directed to the target detector and the outer annulus goes to the reference detector.(8) Within this recess we would find the curved remnants of the angular (the tympanic) which actually form the tympanic annulus .(9) The calcification extended into the mitral annulus .(10) The pipette microchamber introduces a mechanical constraint around the annulus where the pipette tip contacts the plasma membrane.(11) The inner and outer margins of the annulus were observed to bulge outwards but when the nucleus was removed the inner margins bulged inwards.(12) Channel incorporation was typically achieved within a few minutes after u2018brushingu2019 the membrane fraction across the annulus with fresh lipids to form a new bilayer.(13) At the other end, headgroups of phospholipids should form an annulus through which permeating ions must pass to cross the membrane.(14) Mitral valve prolapse occurs when varying portions of one or both leaflets of the mitral valve extend or protrude abnormally above the mitral annulus into the left atrium.(15) The position of the annulus is a key character used to differentiate lineages within the clade.(16) Exploration of the right ear suggested a fistula in the anterior annulus of the oval window, with perilymphatic fluid leak visible on Valsalva at middle ear exploration.
