Mechanics of animal movement
Mechanics is the science of structure and movement that engineers need when they design things like bridges, aeroplanes or machines. It is equally applicable to the structure and movement of organisms, in the branch of science known as biomechanics (Box 1). Biomechanics is concerned with humans, animals, plants and individual cells. Some of its practitioners are motivated principally by curiosi...
متن کاملThe Mechanics of Human Saccadic Eye Movement.
In the investigation of oculomotor systems and especially in the mathematical descriptions of them as pursuit, tracking and stabilizing systems, the need arises for a more exact knowledge of the mechanics of the eyeball, the extraocular muscles and the supporting tissues of the orbit, particularly of the way in which these factors permit the globe to respond to the efferent discharges arising i...
متن کاملSpastic movement disorder: impaired reflex function and altered muscle mechanics.
In clinical practice, signs of exaggerated tendon tap reflexes associated with muscle hypertonia are generally thought to be responsible for spastic movement disorders. Most antispastic treatments are, therefore, directed at the reduction of reflex activity. In recent years, however, researchers have noticed a discrepancy between spasticity as measured in the clinic and functional spastic movem...
متن کاملMechanics, modulation and modelling: how muscles actuate and control movement.
Animal movement is often complex, unsteady and variable. The critical role of muscles in animal movement has captivated scientists for over 300 years. Despite this, emerging techniques and ideas are still shaping and advancing the field. For example, sonomicrometry and ultrasound techniques have enhanced our ability to quantify muscle length changes under in vivo conditions. Robotics and muscul...
متن کاملEye Mechanics And Their Implications For Eye Movement Control
Measurements of eye movements have shown that centrifugal movements (i.e. away from the primary position) have a lower maximum velocity and a longer duration than centripetal movements (i.e. toward the primary position) of the same size. In 1988 Pelisson proposed that these kinematic differences might be caused by differences in the neural command signals, oculomotor mechanics or a combination ...
