Bilamellar

Lamella
Definition:
(n.) a thin plate or scale of anything, as a thin scale growing from the petals of certain flowers; or one of the thin plates or scales of which certain shells are composed.
Example Sentences:
(1) When the aggregates occurred on the cell periphery their position coincided with areas free of lamellae.
(2) The findings indicate that these spaces were lined by a lipid monolayer which formed bilayered lamellae under certain conditions.
(3) The unique structure we describe is a cytoplasmic organelle which, like annulate lamellae, is closely associated with the endoplasmic reticulum and is presumed to be related to the genesis of rough-surfaced endoplasmic reticulum in tumor cells.
(4) New lamellae are formed by these cuboidal cells which then divide and migrate into the lamellae where they assume the characteristic attenuated appearance of fibroblasts in the adult dermal lamellae region.
(5) The antigen (a protein doublet of Mr 75,000-80,000) is present in, but not restricted to, the myelin lamellae, since it is distributed along the whole myelinating Schwann cell membrane.
(6) These data show that the 515 nm absorbance change is not limited to small closed vesicles like grana, but in the presence of suitable electron donors single lamellae of bundle sheath chloroplasts can also be active.
(7) Marginal channels at the tips of the lamellae are lined only by endothelial cells.
(8) The developing distal excretory duct possesses a septate junction and many branching and looping lamellae.
(9) The description of the structure of epithelial cells includes: 1) the endoplasmic reticulum and ribosomes, 2) mitochondria, 3) the nucleus, 4) the golgi complex and secretory bodies, 5) lysosomes, 6) annulate lamellae, 7) luminal surface, 8) basal surface, 9) lateral surface, and 10) the nucleolar channel system.
(10) After upward transposition of the anterior lamella, the excised skin is very suitable for covering the free tarsal surface.
(11) Two autoptic cases of chondroosteoplastic tracheopathy yielded features defining the lesion: continuous shrubby proliferation of the inner surface of tracheal cartilages developed bony lamellae in connection with cells of mucosa.
(12) Those to D1 arise within the dorsal lamella of the PO.
(13) Ultrastructural examination of central nervous tissue from two, perfusion-fixed, 6-month-old foxes showed intramyelin vacuoles resulting from splitting of the myelin lamellae at the intraperiod line and was interpreted as indicating myelin edema.
(14) Such Nissl bodies were composed primarily of several lamellae of granular endoplasmic reticulum with linear arrays of polyribosomes arranged between individual cisternae.
(15) Electron-microscopic examinations of liver biopsies showed various forms of lipoid storage: lipoid bodies with loose, membranous structures and bodies with dense, concentrically arranged lamellae.
(16) The inner layer accounts for the remaining quarter and also consists of lamellae the thread-like turns of which, however, run at a much higher pitch.
