Inferior oblique muscle

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

involves several muscles that contribute to inhalation and exhalation. Muscles of exhalation are mainly located throughout the abdominal region and can be categorized by primary and secondary muscles. There are four primary muscles of exhalation the external oblique, internal oblique, transverse abdominus, and rectus abdominus; also referred to as the abdominal wall muscles. The external oblique is the largest and strongest abdominal muscle in the body. Next the internal oblique although it's not

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 in the aponeurosis of the external oblique. Its apex points superolatetally and its base is formed by

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 and the innermost intercostals is to depress ribs 1-11. The transversus thoracis are

There are about 600 muscles in the body working together to create movement. Muscle contractions pull both ends of the muscle towards one another. One bone attached to each muscle is always more stabilized than the other. The less stabilized bone moves during muscle contraction due to the weaker stability. The points of attachment determine which bone will move. The least movable part is called the origin; it is the part that attaches closer to the midline of the body. This leaves the most movable

Trochlear Nerve (Cranial Nerve IV) is the longest and thinnest nerve emerging from the central nervous system, more specifically the dorsal aspect of the Midbrain, its nucleus is located just below the Oculomotor Nucleus (Cr. 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

Review of literature Thorax is a composed of many integrated systems including the muscles, bones and other soft tissues organ systems, the biomechanics of which, impart the thorax a high mechanical resistance to injury, mainly due to distinctive elastic properties of the rib and spine system supported by muscles. So, understanding the complex mechanics of the thorax is critical for understanding the vast multiplex of injuries sustained in various different circumstances. Anatomy The skeleton
