Muskelspindeln und sensible Endkörper in Harnröhrenschließmuskel

Muscle spindles and encapsulated nerve endings in external urethral sphincter

  • 15 Accesses

  • 12 Citations


Neurohistological investigations of the external urethral sphincter in a 2-day-old female baby proved the up till now not verified existence of muscle spindles. These are rare in number, in the majority containing only one intrafusal fiber. Beside of the spindles encapsulated nerve endings, situated in the interstitial tissue and marginal parts of the muscle fascicles, were detected.
