Basculate

The peridial strand of a basculate aecium is so sensitive to moisture that simply breathing on the open peridium is sufficient to close it immediately.

It shortens the length of the lever arm by means of which the weight of the body and the Achilles tendon tendon makes the calcaneum basculate by carrying its posterior extremity up and the large apophysis down.

It communicates with a spiral copper tube which, by dilatation under the action of the vapours evolved, produces a displacement of the end of the tube which causes a lever to basculate a mercury interruptor.

This favors exercising the spinal column and engaging the muscles and the withers so as to basculate over the obstacle with facility.

The prosthesis also tends to basculate back and forth and in one patient a continuous aqueous leak is observed ( Fig . 37 - VII ) .

It must be taken into account that the pivot stops whithin the coupling region can be responsible for leaflet deceleration, especially in the first closing leaflet, because it can basculate at closure and occupy some of the space at disposal of the second leaflet.

Different excitation thresholds are necessary to basculate the cluster forth and back.

The examiner should basculate the transducer caudally in approximately 45° to facilitate the bladder visualisation.
