After proximal tibial osteotomy, the AP axis was replicated as the AP (O) axis. 2020-06-11 The specification of anteroposterior (AP) axis is a fundamental and complex patterning process that sets up the embryonic polarity and shapes a multicellular organism.

Introduction Pattern formation in th Drosophilae embryo requires the activities of several groups of genes that function in a region-specific manner during early develop-ment. The genes appear to act along either the shorter dorsoventral axis or the longer anteroposter-ior axis of the embryo. The absence of 2016-04-11 10.1055/b-0034-92241 Lower Limb Alignment Full-Length Anteroposterior Standing Radiograph The full-length standing radiograph in the anteroposterior (AP) projection is the basic tool for the radiologic analysis of lower limb alignment. To correctly evaluate the alignment of the lower limbs in the frontal plane, the femoral condyles must be oriented parallel to the X-ray film.

Non-dividing single cells from 10 consecutive regions along the AP axis were isolated by fluorescence activated cell sorting (FACS), and the resulting single-cell cDNA The vertebrate anteroposterior axis forms through elongation of multiple tissues during embryogenesis.

2019-05-15 · Single-cell RNA-seq on cells isolated from 10 distinct anteroposterior (AP) regions and expressed muscle markers was used to identify muscle regionally expressed genes (mRGs). Non-dividing single cells from 10 consecutive regions along the AP axis were isolated by fluorescence activated cell sorting (FACS), and the resulting single-cell cDNA The vertebrate anteroposterior axis forms through elongation of multiple tissues during embryogenesis. This process is based on tissue-autonomous mechanisms of force generation and intertissue mechanical coupling whose failure leads to severe developmental anomalies such as body truncation and spina bifida.

Anteroposterior axis

This process involves the integration of distinct signaling pathways to coordinate temporal–spatial gene … The angular position of a vertebra was defined as the anteroposterior axis with reference in the neutral position to the axis of C0, and in rotation was related to its original axis. patents-wipo The free hinge (40, 42, 80, 96, 98) provides free rotation of the proximal (12) or distal (14) frame member about the anteroposterior axis with respect to the flexion-extension hinge (30, 50, 70, 90, 120).

Anteroposterior axis

Although all echinoderms present bilaterally symmetric larval stages, they dramatically rearrange their body axis and develop a pentaradial body plan during metamorphosis. Therefore, the location of their anteroposterior 眼轴又称前后轴(anteroposterior axis)、矢状轴、y轴(y axis)、几何轴(geometrical axis)、光轴、主轴、长轴(major axis)、视准轴、准直轴(axis of collimation)、光学同心轴、同心共轴、光学轴、主要轴(principal axis)、中心轴(cen-tral axis)、旋转轴(axis of rotation)。 anteroposterior axis A line passing through the anterior and posterior poles and the centre of rotation of the eye.

Anteroposterior axis

This process involves the integration of distinct signaling pathways to coordinate temporal-spatial gene expression and morphogenetic movements. the anteroposterior axis. We have found that a cytoplasmic rearrangement in the uncleaved zygote is directed by the sperm, suggesting a mechanism by which the sperm may specify the axis. The results additionally reveal that the C. elegansoocyte is constructed with no axis prespecified in the form of asymmetrically localised cytoplasmic determi-nants. Medical definition of anteroposterior: concerned with or extending along a direction or axis from front to back or from anterior to posterior.

Volume of thoracic chamber increases in anteroposterior and dorso-ventral axis in human by contraction of diaphragm and external intercostal muscles.

Normally, C. elegans oocytes are fertilised at their leading edge as they pass from the oviduct into the spermatheca. The anteroposterior axis of the tibia was defined as a line perpendicular to the transepicondylar axis and passing through the middle of the posterior cruciate ligament.
