Identify the structure from the given description: It contains the vocal cords. Identify the structure from the given description: A glandular organ near the duodenum. Identify the term: The layer of connective tissue that separates a muscle into small bundles called fascicles. Ident...
Question: Like skeletal muscle, cardiac muscle cells: a. attach to each other via desmosomes b. are striated c. produce tetanic contractions d. all of the above Muscles: There are three different types of muscles found in ...
elegans are oriented not at 90° but at a sharp angle of only 5.9° to the muscle long axis10,11. Dense bodies and M-lines are anchored to the muscle cell membrane and the extracellular matrix, which, in turn, are attached to the hypodermis and cuticle. This allows the transmission of...
Arrows in VIF −/− image highlight long curved microtubule filaments or bundles not seen in VIF +/+ cells. d STORM images of microtubules in VIF +/+ and (e) VIF −/− cells. Zoomed-in images show differences in microtubule curvature. f Microtubule filament curvature analysis from ...
Two diameter ranges were described for the perimysium, the region defining muscle bundles, which contains collagen fibers between 1 and 3 μm and 40–50 nm in diameter [14,15]; however, these parameters significantly change based on age or physiological condition [16]. In addition to ...
Damage to the collagen bundles that constitute the bulk (90% wet weight) of skin connective tissue is another prominent feature of photoaged skin. We have shown that UV irradiation induces synthesis of matrix metalloproteinases (MMP) in human skin in vivo (Fisher et al. 1996,1997). We have ...

Pax7 encodes a transcription factor well-established as an important determinant of mesencephalic identity and superior collicular development. Pax7 mutant mice, however, present with no obvious morphological impairments to the superior colliculus. This
muscle fiber h. multi-nucleate i. sarcoplasm j. sarcoplasmic reticulum Skeletal muscle consists of bundles of long, nonbranched, multinucleated cells called ___. (a) muscle fibers (b) collagen (c) hemoglobin (d) cortisol. (a) State...
Identify the term: Protein found within the thick filaments of a muscle fiber. Identify the structure from the given description: The cytoplasm of a muscle cell. Identify the following: The plasma membrane of a muscle fiber. What is the name of the elongated bundles of contractile proteins that...
