The intimate nature of oculomotor muscles contracture.
The author makes comments about the shortening and loss of elasticity of the oculomotor muscle that remains slack for some time (contracture), by means of a reasoning based on the Hooke s law and on the papers carried out to demonstrate that a muscle that remains relaxed for some time suffers a shortening due to loss of sarcomeres on the longitudinal direction and the increase of the cross-sect...
متن کاملAreview of Dupuytren\'s contracture in 43 hands: assessment of the nature and result after fasciectomy
Abstract Background: Dupuytren's disease is a fibroproliferative disorder of the palmar fascia that can result in disabling contractures of the digits. When function is impeded or deformity is disabling, surgical intervention can be considered, wherein a major problem is recurrence ( reported up to 74%). Although, the disease occurs predominantly in men of northern European, there are ver...
متن کاملOn the nature of visual-oculomotor connections.
Recent results are reviewed describing the behavior of extraocular muscle motoneurons in the alert, behaving monkey during a variety of eye movements, namely, saccades, fixation, pursuit and vergence movements, and vestibular stabilizing movements. Combining this with recent results on the behavior of vestibular neurons, it is possible to present a fairly complete picture of the neuronal arrang...
متن کاملAbnormalities of the oculomotor nerve in congenital fibrosis of the extraocular muscles and congenital oculomotor palsy.
PURPOSE High-resolution magnetic resonance imaging (MRI) can now directly demonstrate innervation to extraocular muscles and quantify optic nerve size. A quantitative MRI technique was developed to study the oculomotor nerve (CN3) and applied to congenital fibrosis of extraocular muscles (CFEOM) and congenital oculomotor palsy. METHODS The subarachnoid portions of the CN3s were imaged with a ...
متن کاملThe oculomotor system of decapod cephalopods: eye muscles, eye muscle nerves, and the oculomotor neurons in the central nervous system.
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 rotations. The arrangement, innervation and action of the decapod eye muscles are compared with those of the seven eye muscles and ...
