What's the difference between aponeurosis and tendon?

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:

  • (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.

Tendon


Definition:

  • (n.) A tough insensible cord, bundle, or band of fibrous connective tissue uniting a muscle with some other part; a sinew.

Example Sentences:

  • (1) Pain is not reported in the removal area, the clinical examinations show identical findings on both patellar tendons, X-ray and ultrasound evaluations do not demonstrate any change in patellar position.
  • (2) Achilles tendon overuse injuries exist as a spectrum of diseases ranging from inflammation of the paratendinous tissue (paratenonitis), to structural degeneration of the tendon (tendinosis), and finally tendon rupture.
