The oculomotor system of decapod cephalopods: eye muscles, eye muscle nerves, and the oculomotor neurons in the central nervous system

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1993
Fourteen extraocular eye muscles are described in the decapods Loligo and Sepioteuthis , and thirteen in Sepia ; they are supplied by four eye muscle nerves. The main action of most of the muscles is a linear movement of the eyeball, only three muscles produce strong ...

Response of oculomotor neurons to eye muscle stretch

Canadian Journal of Physiology and Pharmacology, 1977
Neurons within the ventral portion of the oculomotor nucleus respond to stretch of extraocular muscles. Response latencies range from 30 to 170 ms. Antidromically identified extraocular motoneurons with this input have slowly conducting axons in the range of 30 to 50 m/s.

Oculomotor nerve and muscle abnormalities in congenital fibrosis of the extraocular muscles

Annals of Neurology, 1997
AbstractCongenital fibrosis of the extraocular muscles is an autosomal dominant congenital disorder characterized by bilateral ptosis, restrictive external ophthalmoplegia with the eyes partially or completely fixed in an infraducted (downward) and strabismic position, and markedly limited and aberrant residual eye movements.

Oculomotor system: A dual innervation of the eye muscles from the abducens, trochlear, and oculomotor nuclei

Movement Disorders, 2002
The twitch fibers, orSIFs, are the type of muscle fibers that constitute allskeletal muscles, i.e., they respond to electrical excita-tion with an all-or-nothing response that propagatesalong the whole length of the fiber. They are innervatedby large en plaque motor endplates in an endplate zoneoccupying the central third of the muscle.

The oculomotor nucleus and extraocular muscles in a mutant anophthalmic mouse

The Anatomical Record, 1981
AbstractThe object of this study was to determine whether the oculomotor nucleus and the extraocular muscles are present in the adult of a mutant mouse strain in which eye formation fails early in development (Chase and Chase, '41). Neuronal counts for the oculomotor (IIIrd) nucleus were obtained from serial paraffin sections made through the midbrains

Muscle coenzyme Q10 deficiencies in ataxia with oculomotor apraxia 1

Neurology, 2007
APTX gene mutations responsible for ataxia-oculomotor apraxia 1 (AOA1) were identified in a family previously reported with ataxia and coenzyme Q10 (CoQ10) deficiency. We measured muscle CoQ10 levels in six patients with AOA1 and found decreased levels in five. Patients homozygous for the W279X mutation had lower values (p = 0.003). A therapeutic trial

ASSOCIATED MOVEMENTS IN THE OCULOMOTOR AND FACIAL MUSCLES

Archives of Neurology And Psychiatry, 1946
ABNORMAL motor phenomena belonging—generally speaking—to the vast group of hyperkineses do occur in the oculomotor muscles after incomplete recovery from a third nerve palsy. They constitute, as Bielschowsky 1 rightly said, "a problem of great biologic interest." But this difficult and fascinating problem has been much neglected in the neurologic ...

Oculomotor function in the rhesus monkey after deafferentation of the extraocular muscles

Experimental Brain Research, 2001
The function of extraocular muscle proprioception in the control of eye movements remains uncertain. In this study, we examined the effect of bilateral proprioceptive deafferentation of the extraocular muscles on eye movements in two rhesus monkeys.
