Axons giving rise to the palisade endings of feline extraocular muscles display motor features.
Palisade endings are nerve specializations found in the extraocular muscles (EOMs) of mammals, including primates. They have long been postulated to be proprioceptors. It was recently demonstrated that palisade endings are cholinergic and that in monkeys they originate from the EOM motor nuclei. Nevertheless, there is considerable difference of opinion concerning the nature of palisade ending f...
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 کاملEvidence that the extraocular motor nuclei innervate monkey palisade endings
Palisade endings are found in the extraocular muscles (EOMs) of almost every mammalian species, including primates. These nerve specializations surrounding the muscle fiber insertion have been postulated to be the proprioceptors of the EOMs. However, it was recently demonstrated that palisade endings have a cholinergic nature, which reopened the question of whether palisade endings are motor or...
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...
متن کاملProprioceptive role for palisade endings in extraocular muscles: Evidence from the Jendrassik Maneuver
A proprioceptive hypothesis for the control of eye movements has been recently proposed based on neuroanatomical tracing studies. It has been suggested that the non-twitch motoneurons could be involved in modulating the gain of sensory feedback from the eye muscles analogous to the gamma (gamma) motoneurons which control the gain of proprioceptive feedback in skeletal muscles. We conducted beha...
