Myotendinous nerve endings in human infant and adult extraocular muscles.
Myotendinous nerve endings in extraocular muscles of some mammals consist exclusively of palisade nerve endings incorporated in myotendinous cylinders. There is evidence for a similar form in man, some doubt remains. The objectives of the present study were to examine the structure and distribution of nerve endings in extraocular muscles of infant and adult human material. Muscles from five inf...
متن کاملPalisade endings in human extraocular muscles.
The presence of nerve terminals in the tendinous insertions of human eye muscles was investigated histologically in adult human eye muscles obtained from donor eyes and in muscle pieces resected from juvenile patients undergoing surgical correction for strabismus. Lateral and medial recti, superior and inferior oblique muscles from adults, were stained "en bloc" using a silver impregnation meth...
متن کاملCoordination of the extraocular recti muscles in the cat.
With the use of multiple implanted electrodes in chronic preparations, the electromyograph of the spontaneous activity of the extraocular muscles has been studied in the unanesthetized and unrestrained cat. Simultaneous strain gauge records were also made for monitoring eye movement in acute, restrained preparations with the use of local anesthesia only. It was found that there was a constant o...
متن کاملUltrastructural changes in rabbit extraocular muscles after oculomotor nerve section.
Ultrastructural changes in rabbit superior recti have been studied from 24 hours to 21 days after intracranial section of the oculomotor nerve. Earliest changes were observed in a few myelinated axons within the muscle 24 hours after nerve section. Within 48 hours, degenerative changes in the myelinated axons became manifest and fragmentation of the myelin sheaths started. During the second and...
متن کاملDo palisade endings in extraocular muscles arise from neurons in the motor nuclei?
PURPOSE The purpose of this study was to localize the cell bodies of palisade endings that are associated with the myotendinous junctions of the extraocular muscles. METHODS Rhesus monkeys received tract-tracer injections (tetramethylrhodamine dextran [TMR-DA] or choleratoxin subunit B [CTB]) into the oculomotor and trochlear nuclei, which contain the motoneurons of extraocular muscles. All e...
