Aim: To determine the effects of denervation and treatment with the β2-adrenoceptor agonist, formoterol, on the masseter muscle of the rat. Hypothesis and rationale: Muscles in the craniofacial region, particularly the masseter muscle, are often subject to changes in size and strength as a consequence of post-surgical muscle wasting and neuromuscul...

Context 1
... left side of the rat was arbitrarily chosen as the "experimental" side in all animals. The platysma and masseter muscle fibres were gently parted and the masseteric nerve identified near the sigmoid notch of the coronoid process of the mandible (Figure 1). In the denervated groups, the masseter muscles were surgically denervated through cutting and removal of a 5mm section of the masseteric nerve and its branches en masse. ...
