ABSTRACT
Cranial capacity was measured in Korean adult skulls. The cavity was filled with rice seeds and the volume of the seeds were measured in a graduated cylinder. The results were 1470 +/- 107 (mean +/- standard deviation) in male and 1317 +/- 117 cc in female skulls. These values were in good accordance with those previously reported. In addition, regression formulae were obtained with the product of the length, breadth, and height of the skull as an independent parameter and the measured capacity as a dependent one. With known external measurements, the expected cranial capacity was as follows: when using baso-bregmatic height, male: capacity = 307.5 + 333 x 10(-6) x (length.breadth.baso-bregmatic height) female: capacity = -12.0 + 435 x 10(-6) x (length.breadth.baso-bregmatic height) and, when using auriculo-bregmatic height, male: capacity = 214.6 + 429 x 10(-6) x (length.breadth.auriculo-bregmatic height) female: capacity = 131.6 + 461 x 10(-6) x (length.breadth.auriculo-bregmatic height).

Metric dimensions of skull of Korean adults were measured and the indices of each dimension were calculated to identify the morphological characteristics of neurocrania of Koreans in 97 cases. The results were as follows. The maximal anteroposterior length was 171.6±8.4 (149.0~191.0)mm and the maximal lateral length (maximal breadth) was 142.4±5.4 (128.0~155.0)mm. The horizontal cranial index was 83.3±5.0 and therefore the neurocrania of Koreans were classified to brachycranic type (rounded cranium). The auriculo-bregmatic height was 119.3±5.1mm and basio-bregmatic height was 140.5±4.9mm. The height-breadth index on the basis of the auriculo-bregmatic height was 98.5±3.6, and belong to medium skull. The height-length index was 81.8±3.8, therefore they belonged to high skull. Height-breadth index on the basis of auliculo-bregmatic height was 85.4±5.7, and belonged to medium skull, and the height-length index was 70.5±5.4 and belonged to high skull. In the case of mean height index, the auriculo-bregmatic height was 77.2±5.0 (high skull), basio-bregmatic height was 87.6±2.6 (high skull).

To investigate the variations of the renal segments in Korean adults. the findings of selective renal arteriograms from l3O kidneys were analyzed. The boundary on the lateral surface of the kidney between the areas supplied by anterior and posterior branches of the renal artery was investigated by analysis of the findings of 100 renal arteriograms. In 75% of the cases the boundary was observed to be posterior to the lateral borderline of the kidney and the configuration of it was variable. Under the definition of the segmental artery as the eecorrd branch of the renal artery that could be tied outside the hilum, the distribution of the renal segments was observed. The number of the renal segments in a kidney ranged from 3 to 7 and the frequency was 1.6%. 24.2%. 50.8%. 22.6% and 0.8% in the order of increment. The 5-segment-kidney, the most common form described in many textbooks, was observed in 50.8% of the cases and also was the most common form in this study. In most of the cases(90%) superior and inferior segments were observed. The level of each boundary of the superior and inferior segments was observed on the ventral and dorsal surface of the kidney and compared. The level was identical on both surfaces in 56.1% and 31.8 5t of the superior and inferior segments respectively. The variations in the origin and the number of arteries supplying the superior and inferior segments was compared and the result revealed more complex variations in the former. From the viewpoint of clinical application these results may provide useful information and important suggestions for renal conservative surgery. Considering that the distribution of the renal segments is variable and the number and origin of the arteries supplying the superior and inferior segments, which are frequently indicated for partial nephrectomy. are variable. it may contribute to better surgical results if surgeons observe and decide the resection margin preoperatively by taking the selective renal arteriography from several directions.

Intactness of arterial supplies is necessary for the external ocular muscles to move properly, however the anatomy of the ocular muscular arteries has not been clarified Therefore, 80 orbits of Koreans were dissected under the surgical microscope and the origins of the rectus arteries were observed. The average numbers of the arising site of the artery to the superior rectus, the lateral rectus, the medial rectus, and the inferior rectus were 1.7, 1.2, 2.2 and 1.1, respectively. The superior rectus artery arose from the superolateral muscular artery in 33.3%. The lateral rectus artery arose from the superolateral muscular arterey in 43.8%, from the inferior muscluar artery in 24.8%. The medial rectus artery arose from the inferior muscular artery in 43.1%, from the superomedial musculal artery in 16.8% and from the ophthalmic artery as a solitary branch in 32.9%. The inferior rectus artery arose from the inferior muscular artery in 83.1% and from the inferolateral muscular artery in 13.5%.

The anatomy of the arteries distributing to the ocular rectus muscles has not been well known inspite of their importance during opertions. Eighty orbits of Koreans were dissected under the surgical microscope to find out the entering point and its distribution of each rectus artery. The average numbers of the branches of the artery that piercing the supenor, lateral, medial, and inferior recti were 4, 7, 7 and 6 respectively. The supenor rectus artery tended to pierce the posterior middle one third of the muscle; the medial and lateral rectus arteries tended to pierce the posterior two thirds of the muscles; and the inferior rectus artery tended to pierce the medial two tbrds of the muscle. The arterial branches piercing the anterior one third of the superior rectus were less than 1%, and those of the lateral, medial, and inferior recti were 5%, 10% and 15% respectively. The relationships between the artery and nerve differed in each muscle.

The muscular branches of the ophthalmic artery have been described as the superior muscular artery and the inferior muscular artery. However, the definition of the muscluar arteries and their distribution has not been clarified. Therefore, the muscular branches of the ophthalmic artery in 80 orbits of Korean adults were observed under the surgical microscope. The inferior muscular artery was observed in 87.5% of the materials and the superior muscular artery was observed in 32.5%. The commen muscular branch distributing to the adjacent two muscles was observed more frequently(81.3%). The superior muscular artery and the common muscular branches were similar in their distribution according to their site of origin. Therefore, they were classified into the superolateral and superomedial arteries. The superolateral muscular artery was observed in 58.6%. and the superomedial muscular artery was observed in 71.3%. This study suggests that the ocular muscular arteries are better classified into 3 groups, namely inferior, superolateral, and superomedial muscular arteries.

We studied the variations in the ventral rami of 152 brachial plexuses in 77 Korean adults. Brachial plexus were composed mostly of the fifth, sixth, seventh and eighth cervical nerves and the first thoracic nerve (77.0%). In 21.7% of the cases examined, the fourth, fifth, sixth, seventh and eighth cervical and the first thoracic nerves contributed to the plexus. A plexus composed of the fourth, fifth, sixth, seventh and eighth cervical and the first and second thoracic nerves, and a plexus composed of the fifth, sixth, seventh eighth cervical nerves were also observed. The plexuses were classified into three groups according to cephalic limitation, and the plexus of group 2 in which the whole fifth cervical nerve enters the plexus, were observed the most frequent. The average diameter of the sixth and the seventh cervical ventral rami of the plexus was greatest and that of the fifth cervical was smallest. The largest nerve entering the plexus was the sixth or the seventh cervical nerve in about 79% of cases. The dorsal scapular nerve originated from the fifth cervical ventral ramus in 110 cases (75.8%). The long thoracic nerve was formed by joining of roots from the fifth, sixth, and seventh cervical nerves in 76.0% of cases. Also, a branch to the phrenic nerve, the suprascapular nerve, a nerve to the pectoralis major muscle and a nerve to the subscapular muscle arising from the ventral rami of the plexus were observed.
