The present study attempted to demonstrate the process of connection between these two bone types. We examined sagittal and frontal histological sections from 29 human fetuses with a crown-rump length ranging from 38 to 328 mm (approximately 7-39 weeks of gestational age [GA]). An initial cartilage plate appeared in the posterior side of the fourth ventricle at GA 7-8 weeks and extended inferiorly to connect with the cartilaginous basioccipital and condyle. At GA 9-10 weeks, on the superior side of the cartilage plate, membranous bone fragments appeared and adopted an arrangement resembling a chain of irregularly-shaped beads. They did not form a complete plate-like bone until late-term. At GA 11-12 weeks, endochondral ossification centers appeared at the upper and lower ends of the cartilage plate. At GA 12-15 weeks, a bar-like periosteal bone developed near and superior to the upper ossification center. Notably, sinusoidal structures, which were surrounded by growing periosteal bones, contained island-like clusters of calcified cartilage fragments. Therefore, the upper ossification center appeared likely to \"migrate\" downward and become distant from membranous bones. The extending periosteal bone reached and joined the membranous bone fragments. Consequently, the periosteal bones connected between the endochondral and membranous bones in the OCS. This connection was quite different from the other components of the calvaria, where membranous bones overlap the skull base cartilages at the margin.","PeriodicalId":7831,"journal":{"name":"Anatomy & Cell Biology","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144648350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fusion between these facial primordia implicates formation of an epithelial seam resulting from adherence and fusion between lining epithelia, and its subsequent removal to generate mesenchymal continuity. These embryonic processes involve a complex array of morphogenetic events requiring coordinated cell migration, survival, proliferation, death, patterning, adhesion, and differentiation, involving both the mesenchymal core and the primitive epithelial covering. Perturbation of any of these developmental events can lead to orofacial cleft phenotypes. Cleft lip and cleft palate are the most common congenital head deformities and, in general, among the commonest inborn defects. Indeed, due to the complexity of lip and palate development, the possibility of errors is a real event, therefore their relatively elevate frequency is not surprising. Understanding the pathogenesis of these malformations requires a thorough knowledge of the biological mechanisms underlying normal craniofacial embryogenesis and how they can be disturbed during development. An important contribution to our understanding of the fusion processes occurring in the orofacial district has come from studies on the role of the periderm in the adhesion between embryonic structures. This review summarises the normal morphogenesis of the upper lip/primary palate and secondary palate, as well as the mechanisms of aberrant development leading to cleft lip and palate, with particular attention to the role of the periderm, and cellular and molecular aspects of developmental pathogenesis.","PeriodicalId":7831,"journal":{"name":"Anatomy & Cell Biology","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144641591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, on a skull excavated from the Qau village site during the Old Kingdom period of ancient Egypt (7th to 8th dynasties; 2181-2160 BCE), we found a highly probable sign of therapeutic trepanation in the frontal bone. The practice of trepanation was suggested by the healing sign observed at the site on the frontal bone of case QAU-26. Based on our radiological findings, we presume that this ancient Egyptian male likely suffered from frontal sinus pathology, which may have led to the accumulation of exudates inside the cavity. To alleviate the symptoms of sinusitis, the ancient practitioner may have attempted to induce drainage of exudates from the left frontal sinus by therapeutic trepanation. Our findings are significant in medical history, considering that, thus far, trepanation has been reported rarely in ancient Egyptian civilization. This is also the first reported case of trepanation presumed to have been performed to alleviate paranasal sinusitis, which is of paleopathological and clinical significance.","PeriodicalId":7831,"journal":{"name":"Anatomy & Cell Biology","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144607199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A better understanding of the nerve relationships of the anterior compartment of the leg could be important in treating some patients. Therefore, this study aimed to elucidate the deep fibular nerve and its relationship to various connective tissue bands along its course. Fifty-two cadaveric legs were dissected to reveal and identify the branching patterns of the common, superficial, and deep fibular nerves and their passage through the leg's posterior intermuscular septum (PIMS) and anterior intermuscular septum (AIMS). The oval passageway of the common fibular nerve was classified as the superior fibular band, and the crescentic passageways of the deep and superficial fibular nerves were classified as the middle and inferior fibular bands. The inferior boundary of the oval-shaped superior fibular band of the PIMS was positioned at the lateral aspect of the superior most region of the fibular neck. The crescentic middle fibular band of the AIMS was present in 96.15% of legs, its inferior boundary being consistently positioned in 98% of them. The other 2% presented with a thin band of connective tissue in the absence of a distinguishable AIMS. The crescentic inferior fibular band of the AIMS was present in 17.31% of legs. There were no significant differences between right and left sides in the presence or classifications of the fibular bands. Connective tissue bands along the course of the fibular nerves are common and should be considered in idiopathic palsies of these nerves.","PeriodicalId":7831,"journal":{"name":"Anatomy & Cell Biology","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144551709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The posterior inferior cerebellar artery typically originated from the V4 segment in 76.5%. On the BA morphology, we classified the vessel according to its inclination. The most common type was the J-shaped (55.5% of cases). The BA inclination was positively correlated with the vessel's length (P=0.002). The VBS intracranial segment was systematically investigated.

In fetuses, these bones have been observed to overlap at the junction. The present study examined sagittal, frontal, and horizontal histological sections from 38 human fetuses at a gestational age (GA) of approximately 7-39 weeks. At GA 7-8 weeks, the ala minor extended anterolaterally from the orbitosphenoid, covering the posteromedial quadrant of the roof until GA 9 weeks and reaching to almost the center of the roof at late-term. Simultaneously, the FB appeared in front of the cerebral frontal lobe, reached the anterolateral corner of the roof, and at late-term, it extended posteromedially to cover at least the anterior half of the orbit. In addition, a superolateral plate of the ethmoid, originating from the future cribriform plate, covered the medial marginal part of the roof and had a maximum area at GA 11-16 weeks. At the junction, the FB overlapped and extended below the ala minor or ethmoid. Therefore, at birth, the FB and ala minor seemed to overlap widely at the central one-third of the orbital roof. Because the ala minor was ossified at late-term, postnatal degeneration and absorption were unlikely. The fetal anterior skull base was not flat because of the delayed elevation of the nose and the deeply caved cranial fossa. The overlapping bone and cartilage might slide and migrate, providing materials for reconstruction and later growth of the skull base.","PeriodicalId":7831,"journal":{"name":"Anatomy & Cell Biology","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144526120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
