We examined the dorsal lingual surfaces of an adult eland (Taurotragus oryx) by scanning electron microscopy. Filiform, fungiform and vallate papillae were observed. The filiform papillae of the lingual apex consisted of a larger main papilla and smaller secondary papillae. The connective tissue core of the filiform papilla was U-shaped. The fungiform papillae were round in shape. The connective tissue core of the fungiform papilla was flower-bud shaped. The filiform papillae of the lingual body consisted of a main papilla and were big as compared to that of the lingual apex...

Recently, health awareness in Japan has been increasing and active exercise is now recommended to prevent lifestyle-related diseases. Cytokine activities have many positive effects in maintaining the health of a number of organs in the body. Myokines are cytokines secreted by skeletal muscles in response to exercise stimulation, and have recently generated much attention. Around 700,000 patients in Japan suffer from rheumatoid arthritis, making it the most prevalent autoimmune disease that requires active prevention and treatment...

Fetal cruciate ligaments of the knee provide two types of cartilage attachments: to a cartilage fovea or a simple continuation to the perichondrium. To examine a difference in matrix substance between a ligament attachment to the fovea and another attachment to the perichondrium. We histologically observed 12 human fetal femurs in which the posterior (or anterior) cruciate ligament provided a fovea-type (or a perichondrium-type) attachment. Immunohistochemistry of matric substances (aggrecan, versican, tenascin-c) was performed...

To examine a common plantar tendinous plate for long flexors of the toe and fingers in human embryos, we observed sections of 10 embryos at 5-6 weeks (crown-rump length or CRL 15-21 mm). The heel or tuber of the calcaneus was underdeveloped in 3 embryos with CRL 15 mm and the talus appeared not to be piled up on the calcaneus but these two bones were arranged along the lateromedial axis. As reported in the hand, we demonstrated, in the deep side of tarsal bones, a common tendinous plate formed by a joining of the flexor halluces longus and flexor digitorum longus tendons...

Reported morphologies of the ultimobranchial body had varied between researchers: a cluster of mitotic cells, a duct-like structure and a rosette-like cell mass. To clarify the true morphology, we studied tilted horizontal sections of 20 human embryos (crown-rump length 5-18 mm; 4-6 weeks). The sections displayed a ladder-like arrangement of the second to fourth endodermal pouches and, in 5 early embryos we found the fifth pouch attached to the fifth ectodermal groove near the fourth pharyngeal arch artery...

The posterior superior alveolar canal (PSAC) composed of several canals which contains vessels and nerve in molar region of the maxilla of Japanese macaque. The PSAC of maxilla run to the maxillary sinus. However, the PSAC and accessory canal (AC) of the maxilla in the Japanese macaque (JM) is unknown in morphological features in the maxilla. The purpose of this study was to describe the PSAC of the primates and to determine whether this structure could be used as a model for the human clinical condition. In this study, we showed the course of PSAC structure of the 23 JMs (male: n = 15; female: n = 8) using a cone-beam computed tomography apparatus...

In comparative anatomy, the musculocutaneous nerve is hypothesized to pass between the superficial and deep muscle bellies of the coracobrachialis muscle. The superficial belly is supplied by nerve branches of the lateral cord of the brachial plexus, while the deep belly by the musculocutaneous nerve. Observations of longitudinal sections of ten human embryonic arms (7 weeks; crown-rump length 26-32 mm) demonstrated that the coracobrachialis muscle was always continuous with the short head of the biceps muscle...

The vestibular and geniculate ganglia of the ear in experimental animals carry both of the tyrosine hydroxylase (TH)-positive sympathetic neurons and the neuronal nitric oxide synthase (nNOS)-positive parasympathetic neurons. With an aid of immunohistochemistry, we examined these ganglia as well as the horizontal part of the facial nerve using specimens from 10 formalin-fixed elderly cadavers. The submandibular ganglion from the same cadavers was used for the positive control for both markers. Although there was a nonspecific reaction in nuclei for the present antibody of nNOS, these ganglia were unlikely to contain either nNOS- or TH-positive neurons...

The prostate is a male accessory genital gland that plays an essential role in reproductive function. To understand the cytological characteristics of differentiating prostatic cells, we used lectin histochemistry combined with immunohistochemistry to examine the distribution of lectin-binding sites on prostatic cells during postnatal development in the mouse. During postnatal development, Hippeastrum Hybrid Lectin (HHL) lectin reacted consistently with the luminal cells of all prostatic lobes (regions), whereas the Ricinus Communis Agglutinin I (RCA-I) and Soybean Agglutinin (SBA) lectins showed remarkable differences with age, region, and cell type...
