In this method, which is based on UWB radar imaging, a UWB pulse is transmitted to the transformer winding and the reflection from it is received and recorded By changing the antenna position this process is repeated on several points along the axis of the winding. The measured signals are mapped to a 2-D image of the winding. By analyzing this image, the axial displacement of the winding can detected and the magnitude of it is determined with an acceptable precision. Simulation results are provided to verify the proposed method. Axial Skeleton Research Paper

Anatomy and Physiology of Axial Skeleton

Advanced Search ABSTRACT Many suction-feeding fish use neurocranial elevation to expand the buccal cavity for suction feeding, a motion necessarily accompanied by the dorsal flexion of joints in the axial skeleton.

Axial Skeleton Research Paper

How much dorsal flexion the axial skeleton accommodates and where that dorsal flexion occurs may vary with axial skeletal morphology, body shape and the kinematics of neurocranial elevation. We measured three-dimensional neurocranial kinematics in three species with distinct body forms: laterally compressed Embiotoca lateralis, fusiform Micropterus salmoides, and dorsoventrally compressed Leptocottus armatus. Mean axis link rotation position for neurocranial elevation in E. Although future work must test these hypotheses, our results suggest the relationships merit further inquiry. The neurocranium elevates by rotating dorsally about a transverse axis relative to the body. To produce this elevation, the vertebrae linked Axial Skeleton Research Paper the neurocranium must flex dorsally across one or more intervertebral joints IVJs; this study includes the craniovertebral joint among the IVJs, unless otherwise noted.

INTRODUCTION

Therefore, it has been hypothesized that vertebral morphology is modified for permitting high degrees of neurocranial elevation in some fish Lesiuk and Lindsey, ; Lauder and Liem, ; Huet et al. Despite this interest in vertebral specializations, few studies have explored how the axial skeleton as a Rsearch may affect neurocranial motions and, conversely, how the requirement of neurocranial elevation may influence body shape and axial skeletal structures.

Body shape and the morphology of the axial skeleton have typically been studied in the context of Axil bending of the body for swimming e. Gray, ; Hebrank et al. It is reasonable to expect that they are also relevant to dorsal bending of the body during Axial Skeleton Research Paper feeding but few studies have examined them in Axial Skeleton Research Paper context.

Confirm. Lysander Essays opinion data on both 3D neurocranial kinematics and axial morphology, it is difficult to generate, let alone test, hypotheses of how axial and body morphology relate to neurocranial elevation. In this study, we examine some aspects of axial skeletal morphology Fig. While ligaments, tendons and axial musculature also play important roles in vertebral column flexion, the present study focuses on the axial skeleton and overall body shape.

Axial morphology may be related to the position on the vertebral column where dorsal flexion Reseaech likely to occur during neurocranial elevation. This location can be described as the axis of rotation AOR between the neurocranium and the Axial Skeleton Research Paper of the fish. The AOR is the pivot point between the neurocranium and the body at which neurocranial elevation can be described as pure rotation without translation Fig. As such, the AOR is the centre of rotation, with dorsal flexion of the IVJs likely distributed on either side of it except in rare cases of a single IVJ specialized for dorsal flexion; see below. Several studies have estimated the position of the AOR using morphological observation, specimen manipulation and 2D kinematic analysis. Skeleron on the manipulation of specimens, Gregory suggested that the AOR is located near the post-temporal-supracleithral joint, which Carroll et al. Others have suggested that the AOR is located at the craniovertebral joint based on its specialized morphology Lauder and Liem,or in the case of Rhaphiodon vulpinus, Lesiuk and Lindsey implied that the AOR must be located in the IVJ just posterior to the Weberian apparatus, since the apparatus is relatively immobile.

In other Reseacrh, the AOR has been determined in largemouth bass and pipefish based on modified versions of the Reuleaux method, which estimates the AOR from a 2D kinematic analysis of the position of the neurocranium at rest and at maximum elevation Reuleaux, ; Van Wassenbergh et al.
