JOURNAL FREE ACCESSThe fine structures of the lingual dorsal epithelium in the musk shrew were observed by light and transmission electron microscopy. The results showed that the lingual dorsal epithelium revealed three different cell lines by light microscopy, that is, anterior and posterior cell lines of filiform papillae and an interpapillar cell line. In the posterior cell line of filiform papillae, keratohyaline granules were not observed. Instead, tonofibrils were present in the cells of the deep intermediate layer and hard keratinized cells in the shallow intermediate and surface layers. In the anterior cell line of filiform papillae, keratohyaline granules were found in the intermediate layer. Cells in the surface layer were filled with numerous fibrous structures. Both hard and soft keratinized cells were not apparent in the interpapillar cell line.View full abstractDownload PDF (12209K) -

JOURNAL FREE ACCESSThe peripheral distribution of the medial circumflex femoral artery was examined in 38 lower extremities from 23 Japanese adults. The superficial branch (BNA, INA) passed superficial to the pectineus medially deep to the femoral vein. It has been confused with the external pudendal artery which typically passed superficial to the vein. After extending between the pectineus and the iliopsoas deeply, the stem artery divided into four branches.1) The acetabular branch was found in 14 cases (37%). The obturator artery was also involved in the arterial supply to the acetabulum in all the cases examined, and the inferior gluteal artery participated in it in 18 cases (47%) after connecting with the obturator artery.2) The muscular branch to the anterior surface of the adductor magnus.3) The terminal branch was divided into two and appeared in the posterior aspect of the thigh. The ascending branch was found in 37 cases and emerged from the upper lateral margin of the quadratus femoris to be distributed to the fossa trochanterica. The other vessel was the transverse branch of the PNA and was found in 33 cases. This branch emerged from the lower medial margin of the quadratus femoris to be distributed to the proximal part of the hamstring muscles. The latter vessel passed downwards rather than transversally, so that the term transverse is not appropriate. Anastomoses between the medial and lateral circumflex femoral arteries could not be confirmed macroscopically. Angiographic demonstrations of the arterial network in the proximal end of the femur have been presented in the clinical context.View full abstractDownload PDF (1764K) -

JOURNAL FREE ACCESSThe morphological changes in the pika ampulla coli, especially the net-arranged folds, from the late fetal stage to the adult stage were examined by the naked eye, light microscopy and scanning electron microscopy.
At 25 days of gestation, the ampulla coli could already be discerned from the cecum and the proximal colon by the lack of haustra. In addition to the well-developed muscular coat, the ampulla coli at this stage was provided with a number of short columnar viii. Although the mucosal surface of the ampulla coli was filled with villi until 3 days after birth, a drastic change occurred at 5 days. That is, the villi gathered together at regular intervals and, as a result, the ampulla coli mucosa revealed a net-arranged appearance at 5 days. At 10 days, the villi disappeared completely and net-arranged folds, derived from the gathered villi at 5days, covered the ampulla coli mucosa. After 15 days, small villus-like protrusions on the lateral side of the folds developed secondarily and gradually grew in height in accordance with age. At the adult stage, the ampulla coli was overspread with net-arranged folds equipped with small villus-like protrusions.View full abstractDownload PDF (9732K) -

JOURNAL FREE ACCESSThe duration of various stages of meiosis and spermiogenesis of Heteropneustes fossilis was calculated by following the kinetics of 3H-thymidine labelled spermatocytes autoradiographically. Leptotene lasts less than 12 hours. The duration of pachytene is between 1.94 and 2.20 days. The individual duration of zygotene as well as that of stages from diplotene to metaphase-II is extremely short. Meiosis is completed within 3.34 days whereas spermiogenesis never spans more than 8.50 days. The total duration of meiosis and spermiogenesis does not exceed 11.50 days.View full abstractDownload PDF (1645K) -

JOURNAL FREE ACCESShe present paper aims to describe accurately the shape and size of the transverse foramina in all the cervical vertebrae based on 50 male and 50 female Japanese skeletons. An elliptical shape (about 54%) occurred most frequently, followed by a round shape (about 14%) in all the vertebrae except C2s (superior aspect) and C6. Double foramina (about 11%)were found most frequently in C6 and decreased progressively above and below that level. The main axis of the foramen generally took an anteromedial direction in C1, a frontal direction in C3-C5, and an anterolateral direction in C7. The axis changes its direction strikingly at two points, namely from anteromedial to anterolateral between C7 and C6, and from frontal to anterolateral in the foramen of C2, cranialward. The transverse foramina were significantly greater in males than in females, and on the left side in more than half cases. Its value was largest in C1, followed by C2 and C6, and smallest in C7, though it increased gradually from C3 to C6. Almost identical data were observed in Japanese, Chinese and Indian vertebrae.View full abstractDownload PDF (1758K)
