The digastric muscle is located in the suprahyoid region which consists of anterior belly, intermediate tendon and posterior belly. This muscle is an important landmark when performing an operation of submental and upper neck region. Previous researches have reported about variations of the anterior and posterior belly of digastric muscle. However,there are few studies about the general morphology of the digastric muscle and the relationship with surrounding muscles. The purpose of this study was to analyze the morphology of the anterior belly of digastric muscle and confirm the topographic relationship between the digastric muscle and the stylohyoid muscle of Korean. Thirty-four cadavers (21 males, 13 females; mean age 65 years; range 24~89 years) were used in this study. The skin, subcutaneous tissues, superficial fascia and platysma were removed and a detailed dissection was performed, with extreme care being taken not to damage underlying the muscles of submental and upper neck region. After the dissections,all specimens were sketched and photographed. In 8 specimens, we observed the accessory bellies of the anterior belly of digastric muscle. We classified the accessory bellies into the crossover type (five specimens, 14.7%) that cross the mandibular raphe and unilateral type (three specimens, 8.82%). The findings resulting from observation of the anatomical relationship between the posterior belly of digastric and stylohyoid muscles, the posterior belly of digastric muscle perforated the stylohyoid muscle in 32 cases (65%) out of 49sides. This case was subdivided into the belly of the stylohyoid muscle lean to the lateral (twenty-one specimens,42.9%) or medial side (eleven specimens, 22.4%) of the posterior belly of digastric muscle. In 17 specimens (35%), the stylohyoid muscle existed on the medial side of the posterior belly of digastric muscle.

Left handedness is known to be related with inheritance and is different from right handedness in brain development and various aspects of perceptive and cognitive performance. Fingerprints are also related with inheritance and do not change for the whole life. In addition, individuals have different fingerprints. The aim of the present study was to identify genetic correlation between fingerprints and handedness by examining how different fingerprints are between left handers and right handers. The study group to imprint fingerprints was composed of 55 left handers and 144 right handers of 1063 college students. The reliability of handedness assessment tool was Cronbach’Os α=0.948. The imprinted fingerprints were classified by fingerprint type (arch, radial loop, ulnar loop, whorl). Finger ridges and triradii in fingerprints were also counted. We performed frequency analysis, reliability analysis, cross-tabs analysis, X2 test, independent t-test, paired ttest by SPSS win 15.0 for the data. The left handed males and females exhibited more arch types than the right handers and less whorl types than the right handers. The left handers in both hands exhibited more arch and ulnar loop types than the right handers and less whorl and radial loop types than the right handers. In the left hand, the 3rd (p⁄O0.05), 4th (p⁄O0.05), and 5th (p⁄O0.01)fingerprints of the left handers were different from those of the right handers. The finger ridge counts of left handers were significantly less than those of the right handers in the 2nd and 3rd fingers of the left hand, and in the 3rd and 4th fingers in the right hand. The triradii counts of left handers were significantly less than those of right handers (p⁄O0.05)in the 3rd, 4th, and 5th finger of the left and right hand. Total triradii counts of left handers were also significantly less than those of right handers (p⁄O0.05). These results demonstrate that fingerprint type, finger ridge and triradius counts of the left handers are different from those of the right handers, and fingerprints may reflect genetic tendency for handedness.
