Superior orbital fissure

eosinophils and large numbers of IgG+ plasma cells.[20-23] EOM enlargement is not rare in IgG4-ROD especially in cases with enlarged orbital nerves. Single or multiple muscles may be involved during the disease course in the following order of frequency: inferior rectus, followed by superior rectus-levator complex, lateral rectus, medial rectus, inferior oblique and superior oblique. Histopathologically, the muscle biopsy shows a mixed and dense infiltration with polyclonal B- and T-cells with some fibrosis

left middle cerebral artery enters the left lateral sulcus of Sylvius and it distributes as normally does. The left main single trunk (LMST) runs anteromedially towards the longitudinal cerebral fissure, above the optic tract and optic chiasm. Just at the beginning of the longitudinal cerebral fissure the left main single trunk divides into four branches; the right middle cerebral artery,

III) at the level of the inferior colliculus, its fibers arc around the periaqueductal grey matter, decussate before exiting the midbrain on its dorsal aspect by piercing the superior medullary vellum, goes around its dorsum, passing between the cerebral peduncles and the temporal lobe; then it courses between the Superior and Posterior Cerebral Arteries (SCA, PCA), pierces the dura just beneath the free edge of the Tentorium cerebelli behind the posterior clinoid process, enters the cavernous sinus

Cranial Nerves The human body is a unique and fascinating entity. There is not much notice taken of the features the human body is capable of. The brain is necessary to perform day-to-day actions, such as the ability to speak, and see amongst us. This brain is made up of simple mater (Pia mater, Arachnoid mater, Dura mater) and the cranial surface to protect the brain. We live our daily lives without acknowledging the importance of this organ, the brain, unless you’re a medical student of

the pupil and the movement of the upper eyelid (Jaffee & Stewart, 2016). The oculomotor nerve originates at the two nuclei, the oculomotor nucleus and the Edinger-Westphal nucleus that are at superior colliculus level of the midbrain, travels through the brain and exits through the superior orbital fissure of the sphenoid bone (Jaffee & Stewart, 2016). The nerve consists of two different motor fibers: the somatic motor component and the parasympathetic motor component. The somatic motor component

Different studies showed a possible involvement of the trigeminal cerebrovascular system in the transmission of nociceptive information related to migraine (Link, Kuris, & Edvinsson, 2008). The trigeminocerebrovascular system (Goadsby & Duckworth, 1987), is located in a central position regarding to cerebrovascular physiological influences (May & Goadsby, 1999). It has a unique sensory (afferent) innervation of cerebral vessels (Hamel, 2006) and has, additionally, a potential efferent, in pathophysiological

Schizophrenia is a heterogeneous illness that may involve several pathophysiological gender differences. For men and women incidence risk peaks between 20-29 years of age, and women also have a second risk peak between 30–39 years of age. Negative symptoms including low motivation and withdrawal are more frequent in men and appear up to six years before diagnosis (Hafner, 2005; Hafner et al., 1993; Morgan et al., 2008). Women exhibit greater levels of depression and positive symptoms including sexual
