(18) Muscle fibres were located between internal aponeuroses, between external aponeuroses, between internal and external aponeuroses, between an internal aponeurosis and the periosteum, and between an external aponeurosis and the periosteum.
(19) Since the iliopubic tract inserts into the pubic ramus, a significant gap is created between it and the main transversus aponeurosis which inserts some distance above into the rectus sheath.
(20) One patient also had upper eyelid retraction, which was decreased by excising Müller's muscle and recessing the levator aponeurosis simultaneously with the lower eyelid surgery.
Membrane
Definition:
(n.) A thin layer or fold of tissue, usually supported by a fibrous network, serving to cover or line some part or organ, and often secreting or absorbing certain fluids.
Example Sentences:

(2) The extents of phospholipid hydrolysis were relatively low in brain homogenates, synaptic plasma membranes and heart ventricular muscle.
(3) The patterns observed were: clusters of granules related to the cell membrane; positive staining localized to portions of the cell membrane, and, less commonly, the whole cell circumference.
(4) Activity of Na,K-ATPase activity was measured as a functional marker for synaptosomal membranes.
(5) The influence of the various concepts for the induction of lateral structure formation in lipid membranes on integral functional units like ionophores is demonstrated by analysing the single channel current fluctuations of gramicidin in bimolecular lipid membranes.
(6) Phospholipid methylation in human EGMs is distinctly different from that in rat EGMs (Hirata and Axelrod 1980) in that the human activity is not Mg++-dependent, and apparent methyltransferase I activity is located in the external membrane surface.
(7) The predicted non-Lorentzian line shapes and widths were found to be in good agreement with experimental results, indicating that the local orientational order (called "packing" by many workers) in the bilayers of small vesicles and in multilamellar membranes is substantially the same.
(8) Apparently, the irradiation with visible light of a low intensity creates an additional proton gradient and thus stimulates a new replication and division cycle in the population of cells whose membranes do not have delta pH necessary for the initiation of these processes.
(9) Using monoclonal antibodies directed against the plasma membrane of Madin-Darby canine kidney (MDCK) cells, we demonstrated previously that a glycoprotein with an Mr = 23,000 (gp23) had a non-polarized cell surface distribution and was observed on both the apical and basolateral membranes (Ojakian, G. K., Romain, R. E., and Herz, R. E. (1987) Am.
(10) The fraction of the viral dose which became cell associated was independent of the incubation temperature and increased with increasing target membrane concentration.
(11) Together these results suggest that IVC may operate as a selective activator of calpain both in the cytosol and at the membrane level; in the latter case in synergism with the activation induced by association of the proteinase to the cell membrane.
(12) The Cole-Moore effect, which was found here only under a specific set of conditions, thus may be a special case rather than the general property of the membrane.
