Most of the skeletal musculature supplied by the cranial nerves (special visceral efferent) is pharyngeal. Underfed wobbegongs can be recognised by visibly atrophied dorsal musculature. The cause is believed to be muscle tension or spasms within the affected musculature. Hip migration can be managed by soft tissue procedures such as adductor musculature release. The skull also shows adaptations towards a very powerful jaw musculature. The pectoral musculature of the kakapo is also modified by flightlessness. It likely relied on support from the animal's abdominal musculature. Cryptodiran neck retraction is also dependent on associated cervical musculature for its characteristic motions. Modern humans are unique in the musculature of their forearm and hand. The trabecular dentine contains patches of fibers suggesting attachments to the epaxial musculature. There may be denervation of striated musculature on the electromyogram. Hogun's superior musculature and metabolism grants him superhuman levels of stamina. Uterine atony is a loss of tone in the uterine musculature. The first test is an extension of the dorsal musculature. These drugs stimulate beta-2 receptors present in the bronchial musculature.
