Iris dilator muscle the superior orbital fissure. From there, they travel with the nasociliary nerve and then the long ciliary nerve. They then pierce the sclera, travel between sclera and choroid to reach the iris dilator muscle. They will also pass through ciliary ganglion and travel in short ciliary nerves to reach the iris dilator muscle. The pupillary dilator acts to increase the size of the pupil to allow more light to enter the eye. It works in opposition to the pupillary constrictor. Pupil dilation occurs when there is insufficient light for the normal function of the eye, and during heightened sympathetic activity,
Muscle imbalance with the joint centered, thus accomplishing human movement Muscles that have become imbalanced are usually result of either adaption or dysfunction, they can be classed as functional or pathological. Classic symptoms of muscle imbalances are usually pain associated with the affected joint. Symptoms can vary depending on what stage their muscular imbalance is, functional or pathological, but commonly exhibit small tissue damage or lesions accompanied by a change in muscle movement patterns. Symptoms may occur after injury or surgery, where the recuperation of the joint affected is left untreated causing either tension or restriction to flexibility and strength of the
