Acquired medullated nerve fibres.
Myelination of nerve fibres normally stops at the lamina cribrosa. When it does proceed beyond the lamina cribrosa, it is believed to do so shortly after birth. A patient is recorded in whom medullated nerve fibres developed in the retina during adult life.
متن کاملSchwann cell proliferations mimicking medullated retinal nerve fibers.
Ophthalmoscopically visible white patches in the optic nerve head and adjacent retina in a rhesus monkey histologically represented peripheral rather than central nervous myelin. This case of Schwann cell proliferations appearing as medullated retinal nerve fibers raises questions concerning the relationship of this phenomenon to developmental and acquired lesions of the optic nerve head in man.
متن کاملConduction in Nerve Fibres
Data by E. A. Blair and Erlanger on the voltage-capacity curves and the nerve impulse velocities of each of several fibres in the same nerve trunk are related to Rashevsky's equation for the velocity of transmission in nerve. The results lend support to Rashevsky's analysis. Other empirical relations between the velocity and the parameters of the excitation equations indicate the correctness of...
متن کاملendometrial nerve fibres in endometriosis
endometriosis is a common gynaecological disease that can cause severe pelvic pain such as dysmenorrhoea and dyspareunia, however the mechanisms by which pain is generated are not well understood. nerve fibres in endometriotic plaques have been reported by several authors. we have recently demonstrated the presence of unmyelinated sensory nerve fibres (using the pan-neuronal marker pgp9.5) in t...
متن کاملTreponema pallidum in nerve fibres.
Ultrathin sections of a rabbit scrotal syphiloma were examined by electron microscopy. Treponemes were observed in the endo-, peri-, and epineurium of the nerve fibre. The significance of these findings, in that infection may be transmitted via the nerve fibres and pain reduced by damage to the afferent fibres, are discussed.
