What's the difference between aponeurosis and muscle?

Aponeurosis


Definition:

  • (n.) Any one of the thicker and denser of the deep fasciae which cover, invest, and the terminations and attachments of, many muscles. They often differ from tendons only in being flat and thin. See Fascia.

Example Sentences:

  • (1) (1) The superficial layer (external oblique aponeurosis).

  • (14) The small differences of geometry between isometric and dynamic conditions are presumably due to the lower muscle force in the dynamic condition and the elastic behaviour of the aponeurosis.

  • (17) The advantages of this implant's design permit stabilization of small epiphyseal fragments with minimal interference of joint function and perhaps a reduction of irritation of the extensor aponeurosis.
  • (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.

Muscle


Definition:

  • (n.) An organ which, by its contraction, produces motion.
  • (n.) The contractile tissue of which muscles are largely made up.
  • (n.) Muscular strength or development; as, to show one's muscle by lifting a heavy weight.
  • (n.) See Mussel.

Example Sentences:

  • (1) The extents of phospholipid hydrolysis were relatively low in brain homogenates, synaptic plasma membranes and heart ventricular muscle.
  • (2) It was found that the skeletal muscle enzyme of the chick embryo is independent of the presence of creatine and consequently is another constitutive enzyme like the creatine kinase of the early embryonic chick heart.
  • (3) These immunocytochemical studies clearly demonstrated that cells encountered within the fibrous intimal thickening in the vein graft were inevitably smooth muscle cell in origin.
  • (4) We have amended and added to Fabian's tables giving a functional assessment of individual masticatory muscles.
  • (5) During the performance of propulsive waves of the oesophagus the implanted vagus nerve caused clonic to tetanic contractions of the sternohyoid muscle, thus proving the oesophagomotor genesis of the reinnervating nerve fibres.
  • (6) Muscle weakness and atrophy were most marked in the distal parts of the legs, especially in the gastrocnemius and soleus muscles, and then spread to the thighs and gluteal muscles.
  • (7) No monosynaptic connexions were found between anterodorsal and posteroventral muscles except between the muscles innervated by the peroneal and the tibial nerve.
  • (8) Thus adrenaline, via pre- and post-junctional adrenoceptors, may contribute to enhanced vascular smooth muscle contraction, which most likely is sensitized by the elevated intracellular calcium concentration.
  • (9) In addition to their involvement in thrombosis, activated platelets release growth factors, most notably a platelet-derived growth factor (PDGF) which may be the principal mediator of smooth muscle cell migration from the media into the intima and of smooth muscle cell proliferation in the intima as well as of vasoconstriction.
  • (10) Further, the maximal increase in force of contraction was measured using papillary muscle strips from some of these patients.
  • (11) Peripheral eosinocytes increased by 10%, and tests for HBsAg, antiHBs, antimitochondrial antibody and anti-smooth muscle antibody were all negative.
  • (12) When subjects centered themselves actively, or additionally, contracted trunk flexor or extensor muscles to predetermined levels of activity, no increase in trunk positioning accuracy was found.
