The intimate nature of oculomotor muscles contracture

A natureza íntima da contratura do músculo oculomotor

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-sectional area due to the increase of collagen tissue in the perimysium and the endomysium.
