A hitherto unrecognized muscle bundle in the left ventricular outflow tract is described. Found between the left coronary aortic semilunar cusp and the anterior leaflet of the mitral valve, this anterolateral muscle bundle of the left ventricle is present in approximately 40 percent of normal hearts. On embryologic grounds it is suggested that this bundle is a muscular remnant of the left extremity of the bulboatrioventircular flange. It can be very prominent, causing obstruction of both the left ventricular inflow and outflow tracts.

Background: Botulinum toxin is an attenuated neurotoxin of Clostridium Botulinum gram positive bacterial, which is used in medication sialorrhea, cervical dystonia, hyperhidrosis and non-surgical cosmetic operation (aesthetic) such as facial wrinkles and reduced the bulky appearance hypertrophied of masseter muscle. This study was designed to revealed the effect of zygomiticus inoculation of botulinum toxin B in zygomatic muscle of rats on zygomatic bone.
Methods: A total of 25 male albino rats (200-260 gm) were injected facial intramuscular by a single dose of 2.

Background: The purpose of this study was to clarify the relationships of the tibialis anterior tendon (TAT) and peroneus longus tendon (PLT) with articular cartilage degeneration on the medial cuneiform and first metatarsal.
Methods: We examined 100 feet from 50 Japanese cadavers. The TAT was classified into 4 types based on attachment site area and number of fiber bundles: Type I, two fiber bundles with equal (within 20%) attachment site areas on the first metatarsal and medial cuneiform; Type II, with two fiber bundles and a larger (>20%) attachment site area on the medial cuneiform than on the first metatarsal; Type III, with two fiber bundles and a larger (>20%) attachment site area on the first metatarsal than on the medial cuneiform; and Type IV, with three fiber bundles.

Background: Pelvic trauma can have long-lasting debilitating effects, including severe erectile dysfunction (ED) in men. While there are effective treatments for ED, these treat the symptoms not the cause. Those who suffer from an acute traumatic injury to the neurovascular supply of penis, may benefit from regenerative therapy.

Introduction: In individuals with chronic post-stroke hemiparesis, slow walking speed is a significant concern related to inadequate propulsion of the paretic limb. However, an overlooked factor is this population's altered morphology of the Achilles tendon, which may compromise the propulsive forces by the paretic limb. This study aimed to explore changes in Achilles tendon morphology, including gross thickness and intra-tendinous collagen fiber bundle organization, following stroke-induced brain lesions.
