What's the difference between sarcolemma and striated?
Sarcolemma
Definition:
(n.) The very thin transparent and apparently homogeneous sheath which incloses a striated muscular fiber; the myolemma.
Example Sentences:

(9) The rate of nonspecific (non-receptor protein) drug binding to highly purified sarcoplasmic reticulum membranes essentially devoid of specific receptors for these drugs appears to be extremely fast, at least 10(3) times faster than specific drug binding to the receptor in the sarcolemma.
(10) This result suggests that felodipine may inhibity Ca++ release from intracellular Ca++ stores through a mechanism of Ca++ or inositol 1,4,5-triphosphate induced Ca++ release in addition to a blockade of Ca++ influx through the sarcolemma.
(11) An accompanying outward release of protons from localized regions of the sarcolemma (Ca2+ channels?)
(12) These confocal microscopic observations suggest that dystrophin may be localized in a nonuniform, discontinuous pattern along the sarcolemma and in some relationship with the underlying myofibrils.

(14) These membranes are identified as being of sarcolemmal origin by enrichment of marker activities associated with the sarcolemma (e.g., binding of the ligands PN 200-110, iodocyanopindolol, and ouabain).
(15) Thick and thin myofilaments appear first in the cell periphery near the sarcolemma.

(18) Subsarcolemmal S1-decorated actin filaments had mixed polarity and attached to the sarcolemma at one end.
(19) This is consistent with the hypothesis that a small net influx of Ca2+ across the sarcolemma during long diastoles was responsible for loading of the reticulum and enhancement of F at low frequencies.
(20) Fast twitch fibres of rat and rabbit show rectangular patterns of intramembrane particles in freeze-fracture preparations of the sarcolemma.
Striated
Definition:
(imp. & p. p.) of Striate
(a.) Marked with striaae, or fine grooves, or lines of color; showing narrow structural bands or lines; as, a striated crystal; striated muscular fiber.
Example Sentences:

(2) Striated muscle fibres were found in each of twenty consecutive pineal glands cultured from individual neonatal rats.2.
(3) Structural studies indicate that caveolae are decorated on their cytoplasmic surface by a unique array of filaments or strands that form striated coatings.
(4) Between the 3rd and 4th week following amputation, the first fully differentiated striated muscle cells appear, and in the 6th week myogenic differentiation extends throughout the regenerate.
(5) An enzymatic and immunologic study of 18 patients with trichinosis leads to the following conclusions: The stage of muscular invasion in trichinosis is accompanied by a release of cellular enzymes representative of striated muscle fibres in nearly all the cases.
(6) We show that over a limited range of high spatial frequencies this noise takes on a striated appearance, with the striations running perpendicular to the true fringe orientation.
(7) We tentatively suggest that a preferential loss of contrast sensitivity to horizontal gratings might be due to a functional abnormality in the striate cortex that relatively spares the extrastriate cortex.
(8) When the blind monkey sleeps, the bizarre EEG is replaced by patterns wholly normal in appearance,32 indicating that some nonvisual system has extensive access to striate cortex in this state.
(9) In 60 consecutive patients clinically suspected of having chronic pancreatitis the serum concentration of the immunoglobulins (IgA, IgG, IgM), the IgG- and IgA-type non-organ-specific autoantibodies against nuclear material (ANA), smooth and striated muscle, mitochondria, basal membrane, and reticulin, and the IgG- and IgA-type pancreas-specific antibodies against islet cells, acinus cells, and ductal cells (DA) were estimated blindly.
(10) Three days following implantation of 2 x 10(5) tumor cells onto the striated skin muscle, capillary sprouts were noted in the tumor cell mass.
(11) Lateral peristriate differences were less than those of striate cortex, and regions of greater and lesser monocular input could be distinguished.
