altogether. Jeon-Min Hwang and associates found that the absence of the CHN1 caused the subsequent absence of cranial nerves IV and VI (18). Cranial nerve four, also known as the trochlear nerves, serves to lower the eye as it is adducted by the superior oblique muscles; in

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.[24, 25] IgG4-ROD may also involve

inguinal ring is located midway between the anterior superior iliac spine and the pubis symphysis, lying just above the inguinal ligament and immediately lateral to the inferior epigastric vessels. The deep inguinal ring is the beginning of the tubular evagination of transversalis fascia that forms one of the coverings of spermatic cord and the round ligament of the uterus (Drake, 2010). The end of inguinal canal, the superficial inguinal canal, is superior to the pubis tubercle and has a triangular opening

extrinsic eye muscles that are primarily responsible for eye movement.” The three nerves that contribute to human eye movement are: oculomotor, abducens and trochlear nerve. The oculomotor is a pure motor nerve, “that controls the superior, inferior and medial rectus,” (Marieb, 495) The abducens nerve is a purely motor nerve that carries motor impulses to the lateral rectus that permits the eye to move side to side and abduct. The trochlear nerve innervates the superior oblique eye muscle that allows

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

Thoracic muscles involved in forced expiration include the interosseous portion of the internal intercostals, innermost intercostals, transversus thoracis, subcostals, and serratus posterior inferior. The function of the interosseous portion of the internal intercostals

On the first day of our dissection process, the group before us also had the right portion of the back, which includes the following muscles: Trapezius, Latissimus dorsi, Triangle of auscultation, Lumbar triangle, Blood vessels and nerves, posterior triangle of neck, Rhomboid major, Rhomboid minor, Levator scapulae, Serratus posterior superior and inferior, Splenius capitis, Semispinalis, erector spinae, and Multifidus. Once it was our turn for the dissection process of the cadaver, the previous
