The Superficial Glia Limitans of Mouse and Monkey Brain and Spinal Cord
ABSTRACT Using the double immunostaining method, the glia limitans on the surfaces of mouse and monkey brain and spinal cord were studied systematically. The results showed that the superficial glia limitans of mouse brain and spinal cord comprise a layer of surface astrocytes, while the glia limitans of monkey comprise a layer of foot‐plates from marginal regions as described in histology and neuroscience textbooks. These surface astrocytes first appear at embryonic day (E)16 in spinal cord and at E17 on the ventral surface of the brain. At postnatal day (P)1, a layer of astrocytes covered the outermost regions of the s...

Serial slice image segmentation of digital human based on adaptive geometric active contour tracking
Abstract: Segmentation is one of the crucial problems for the digital human research, as currently digital human datasets are manually segmented by experts with anatomy knowledge. Due to the thin slice thickness of digital human data, the static slices can be regarded as a sequence of temporal deformation of the same slice. This gives light to the method of object contour tracking for the segmentation task for the digital human data. In this paper, we present an adaptive geometric active contour tracking method, based on a feature image of object contour, to segment tissues in digital human data. The feature image is const...

Airway Morphology From High Resolution Computed Tomography in Healthy Subjects and Patients With Moderate Persistent Asthma
In this study, a commercial software package was used to segment the airway tree of seven healthy and six moderately persistent asthmatic patients from high resolution computed tomography images. The process was assessed with regards to the treatment of the images of the asthmatic group. The in vivo results for the bronchial length, diameter, WT, branching, and rotation angles are reported and compared per generation for different lobes. Furthermore, some popular mathematical relationships between these morphometric characteristics were examined in order to verify their validity for both groups. Our results suggest that, e...

Ontogenetic patterns of morphological variation in the ectocranial human vault
ABSTRACT The skull is considered a modular structure in which different parts are influenced by different factors and, as a result, achieve adult shape at different ages. Previous studies have suggested that the basicranium presents a modular pattern that distinguishes sagittal and lateral parts, probably affected by the brain and masticatory structures, respectively. The vault of modern humans, in contrast, has been considered as a highly integrated system mainly influenced by brain growth. Here, we explored developmental shape variation in sagittal and lateral ectocranial vault in humans in order to assess if both region...

Imaging of Vascular Complications and Their Consequences Following Transplantation in the Abdomen [Multisystem Radiology]
This article includes a basic description of the standard surgical techniques performed in the abdomen, with emphasis on the relevant vascular anastomotic reconstructions used. Posttransplantation complications can be broadly classified as vascular or nonvascular in origin. Many of these complications can be accurately depicted and characterized at imaging and dealt with definitively by using interventional radiology techniques, which can be graft- and life-saving and can obviate further complex surgical intervention. The article discusses imaging appearances of vascular complications and their consequences after transplan...

Osteology and Radiographic Anatomy of the Pelvis and Hind Limb of Healthy Ring‐Tailed Lemurs (Lemur catta)
Summary In family Lemuridae, anatomical variations exist. Considering its conservation status (near threatened) and presence of similarities between strepsirrhines and primitive animals, it was thought to be beneficial to describe the gross osteology and radiographic anatomy of the pelvis and hind limb of ring‐tailed lemurs (Lemur catta) as a reference for clinical use and species identification. Radiography was performed in 14 captive adult ring‐tailed lemurs. The radiographic findings were correlated with bone specimens from two adult animals. Additionally, computed tomography of the hind limbs was performed in one a...

Comparison between endoscopic and microscopic stapes surgery
ConclusionEndoscopic surgery is particularly suitable for stapedial disease. Endoscopic stapes surgery can even be done in patients with a curved and narrow external auditory canal. Endoscopic surgery is also suitable for education: The surgical anatomy can be understood easily and both the surgeon and assistants can observe the procedure on the same monitor. However, it should only be performed by experienced surgeons because one‐handed manipulation is required and stereoscopic vision is not available. Level of Evidence3b.

Recent advances in endoscopic management of difficult bile duct stones
Endoscopic treatment is now recognized worldwide as the first‐line treatment for bile duct stones. Endoscopic sphincterotomy combined with basket and/or balloon catheter is generally carried out for stone extraction. However, some stones are refractory to treatment under certain circumstances, necessitating additional/other therapeutic modalities. Large bile duct stones are typically treated by mechanical lithotripsy. However, if this fails, laser or electrohydraulic lithotripsy (EHL) is carried out under the guidance of conventional mother‐baby cholangioscopy. More recently, direct cholangioscopy using an ultrathin ga...

Some unusual types of formation of the ansa cervicalis in humans and proposal of a new morphological classification
Ansa cervicalis (ansa hypoglossi) is a peripheral nerve structure—the primary choice for laryngeal reinnervation. Because the ansa formation is quite variable in humans, it is an object of a number of proposed classifications. Two interesting cases of formation of the ansa cervicalis were found during routine anatomical dissections. In the first case the unusual ansa had three basic roots—a superior one from the hypoglossal nerve, an aberrant middle root from the vagus nerve and an inferior root, coming from the cervical ventral branches. In the second case an ansa was described having roots from the vagus nerve and ce...

Cranial Muscle Development in the Model Organism Ambystoma mexicanum: Implications for Tetrapod and Vertebrate Comparative and Evolutionary Morphology and Notes on Ontogeny and Phylogeny
We describe different and complementary types of general muscle morphogenetic gradients in the head: from anterior to posterior, from lateral to medial, and from origin to insertion. Furthermore, even during the development of neotenic salamanders such as axolotls, various larval muscles become indistinct, contradicting the commonly accepted view that during ontogeny the tendency is mostly toward the differentiation of muscles. We provide an updated comparison between these muscles and the muscles of other vertebrates, a discussion of the homologies and evolution, and show that the order in which the muscles appear during ...

Anatomy and development of the larval nervous system in Echinococcus multilocularis
Conclusions: We provide evidence for the first time of the existence of a nervous system in the metacestode cyst wall, which is remarkable given the lack of motility of this larval stage, and the lack of serotoninergic and cholinergic elements. We propose that it could function as a neuroendocrine system, derived from the nervous system present in the bladder tissue of other taeniids. The detailed description of the development and anatomy of the protoscolex neuromuscular system is a necessary first step toward the understanding of the developmental mechanisms operating in these peculiar larval stages.

Management of cerebrospinal fluid leak during endoscopic pituitary surgery
Conclusion: The dural flap technique we employ has several advantages. First of all, it allows optimal physiological reconstruction after the surgery. Secondly, the bridge between the flap and the main dura helps maintain the vascular supply, which in turn can radically shorten the healing time. Thirdly, this technique is obviously a better alternative to the time consuming and expensive multilevel closures with tissue sealants and artificial grafts. (Source: Auris, Nasus, Larynx)

Reconstruction of Acquired Oromandibular Defects
Acquired defects of the mandible resulting from trauma, infection, osteoradionecrosis, and ablative surgery of the oral cavity and lower face are particularly debilitating. Familiarity with mandibular and cervical anatomy is crucial in achieving mandibular reconstruction. The surgeon must evaluate which components of the hard and soft tissue are missing in selecting a method of reconstruction. Complexity of mandibular reconstruction ranges from simple rigid internal fixation to microvascular free tissue transfer, depending on defect- and patient-related factors. Modern techniques for microvascular tissue transfer provide a...
