WebJul 30, 2024 · Development of the vertebrae begins with the accumulation of mesenchyme cells from each sclerotome around the notochord. These cells differentiate into a hyaline cartilage model for each vertebra, which then grow and eventually ossify into bone through the process of endochondral ossification. WebThe notochord derives during gastrulation (infolding of the blastula, or early embryo) from cells that migrate anteriorly in the midline between the hypoblast and the epiblast (inner …

The notochord is a long, rodlike structure that develops dorsal to the gut and ventral to the neural tube. The notochord is composed primarily of a core of glycoproteins, encased in a sheath of collagen fibers wound into two opposing helices. The glycoproteins are stored in vacuolated, turgid cells. These cells … See more In anatomy, the notochord is a flexible rod which is similar in structure to the stiffer cartilage.

WebNotochord: differentiates into nucleus pulposus of the intervertebral disk The entire nervous system develops from the ectoderm . Neural tube defects are one of the most common CNS malformations and develop as a result of incomplete closure of the neural tube (e.g., spina bifida , anencephaly ). WebThe notochord causes the ectoderm above it to form a thick flat plate of cells called the neural plate. The neural plate extends the length of the rostral-caudal axis. The neural plate then bends back on itself and seals itself into a tube known as the neural tube that fits …
