  • Title: Degeneration and regeneration of some mechanoreceptors. An ultrastructural study. IV. Ultrastructure of reinnervated Pacinian corpuscles.
    Author: Chouchkov C.
    Journal: Z Mikrosk Anat Forsch; 1979; 93(3):433-41. PubMed ID: 516850.
    Abstract:
    The first signs of reinnervation of the Pacinian corpuscles have been established at the middle of the second month after nerve crush. The regenerative process pass through two periods. During the first period the progressive increase of the Schwann receptor cells has been observed parallel to the reduction of the regenerating nerve branches. During the second period the reorganization and renewal of the regenerated organelles takes place. Some organelles as dense core vesicles, coated vesicles and microtubules of the receptor nerve fibre show noticeable dynamics. The regeneration has been established only in the preexisting after denervation capsulated remnants of the receptors. After nerve transection the regeneration is prolonged one month later and the less of quantity reinnervated receptors have been observed.
