Anteroposterior Axis in Planarians Graphical Abstract Highlights d A tail-to-head Wnt signaling gradient exists along the planarian A/P axis d The gradient patterns the expression of tail genes, including Wnt components d Autoregulatory feedback governs gradient formation and maintenance d The global A/P pattern depends on mutual tail-head

The Wnt family of secreted proteins has been proposed to play a conserved role in early specification of the bilaterian anteroposterior (A/P) axis. 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. The specification of anteroposterior (AP) axis is a fundamental and complex patterning process that sets up the embryonic polarity and shapes a multicellular organism. This process involves the integration of distinct signaling pathways to coordinate temporal-spatial gene expression and morphogenetic movements. the anteroposterior axis.

At the level of the tibial plateau and the patellar tendon attachment, the mean medial percentage width of intersecting point of the patellar tendon and the anteroposterior axis was 10.8% +/- 9.8% Anteroposterior Axis in Planarians Graphical Abstract Highlights d A tail-to-head Wnt signaling gradient exists along the planarian A/P axis d The gradient patterns the expression of tail genes, including Wnt components d Autoregulatory feedback governs gradient formation and maintenance 1998-11-01 2015-09-25 A previous study highlighted the importance of the presomitic mesoderm (PSM) in elongation and showed that a gradient of random cell motility along the anteroposterior axis is necessary for proper elongation of the chicken embryo. It was proposed that a gradient of random cell motility, downstream of a morphogen gradient, drives axis extension. Anterior Posterior Axis The Growth Plate.

expression, anteroposterior axis. 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

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. This process involves the integration of distinct signaling pathways to coordinate temporal–spatial gene expression and morphogenetic movements.

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.

The axis appears to be determined very early in   Anteroposterior Axis Determination.

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. Similar to other morphogenetic modules, anteroposterior body extension requires both Adverb. anteroposteriorly ( not comparable ) ( biology) Along the anteroposterior axis quotations .
