The chordamesoderm is the central region of trunk mesoderm. [4] This forms the notochord, which induces the formation of the neural tube, and establishes the anterior-posterior body axis. The notochord extends beneath the neural tube from the head to the tail. The mesoderm moves to the midline until it covers the notochord.
This article is about the role of fibroblast growth factor signaling in mesoderm formation. Mesoderm formation is a complex developmental process involving an intricate network of signaling pathways that coordinate their activities to ensure that a selective group of cells will eventually give rise to mesodermal tissues in the adult organism.

The mesothelium is a membrane composed of simple squamous epithelial cells of mesodermal origin, [2] which forms the lining of several body cavities: the pleura (pleural cavity around the lungs), peritoneum (abdominopelvic cavity including the mesentery, omenta, falciform ligament and the perimetrium) and pericardium (around the heart).

SNAI1 and other epithelial-mesenchymal transition (EMT) genes are regulated by several genes and molecules including Wnt and prostaglandins. Wnt3a is a master regulator of paraxial presomatic mesoderm cells (PSM) which differentiate into the musculoskeleton of the trunk and tail.
The face and neck development of the human embryo refers to the development of the structures from the third to eighth week that give rise to the future head and neck.They consist of three layers, the ectoderm, mesoderm and endoderm, which form the mesenchyme (derived form the lateral plate mesoderm and paraxial mesoderm), neural crest and neural placodes (from the ectoderm).

Therefore, the tip of the trunk grows rapidly and is not shadowed by branches. If the dominant meristem is cut off, one or more branch tips will assume dominance. The branch will start growing faster and the new growth will be vertical. Over the years, the branch may begin to look more and more like an extension of the main trunk.
