What does the paraxial mesoderm give rise to?
axial skeleton
The paraxial mesoderm gives rise to the axial skeleton. The lateral plate mesoderm gives rise to the appendicular skeleton.
What is the result of somite differentiation?
Differentiation within the somite. Somites form (1) the cartilage of the vertebrae and ribs, (2) the muscles of the rib cage, limbs, and back, and (3) the dermis of the dorsal skin. However, as the somite matures, its various regions become committed to forming only certain cell types.
What does intermediate mesoderm give rise to?
The intermediate mesoderm develops into vital parts of the urogenital system (kidneys, gonads and respective tracts), as well as the reproductive system.
What does the Dermomyotome give rise to?
Dermomyotome is an epithelial cell layer constituting of the dorsal part of the somite lying under the ectoderm. As its name implies, it will give rise to dorsal dermis and to the skeletal muscle of the myotome, as well as the precursor cells of other skeletal muscles.
What are somite cells?
Somites are precursor populations of cells that give rise to important structures associated with the vertebrate body plan and will eventually differentiate into dermis, skeletal muscle, cartilage, tendons, and vertebrae. Formation begins as paraxial mesoderm cells organize into whorls of cells called somitomeres.
What develops from intermediate cell mass?
The intermediate mesoderm develops into the urogenital system, which includes the kidneys and gonads, and their respective duct systems, as well as the adrenal cortex. The intermediate mesoderm forms paired elevations called urogenital ridges.
Does intermediate mesoderm give rise to the heart?
Somites contribute to the axial skeleton and muscles. The lateral plate mesoderm contributes to the heart, limbs, blood vessels, and gut. Between these two mesoderm tissues is the IM, which makes the kidneys and reproductive tracts.
Are there progenitors in the head paraxial mesoderm?
Head paraxial mesoderm contains progenitors for many tissues in addition to skeletal muscle. These include cartilages and bones associated with the braincase, loose connective tissues such as meninges and adipocytes, and endothelial cells.
Where is the mesoderm located in a paraxial Chick?
* Paraxial mesoderm: red, at somite. * Intermediate mesoderm: purple, near Wolffian duct. * Lateral plate mesoderm: purple, near “Somatic mesoderm” and “Splanchic mesoderm”. Chick embryo of thirty-three hours’ incubation, viewed from the dorsal aspect. (Paraxial mesoderm labeled at left.)
What is the role of BMPs in the paraxial mesoderm?
Formation and somitogenesis. The paraxial and other regions of the mesoderm are thought to be specified by bone morphogenetic proteins, or BMPs, along an axis spanning from the center to the sides of the body. Members of the FGF family also play an important role, as does the WNT pathway.
What are the different types of paraxial deficiencies?
In paraxial deficiencies a part is absent in the length axes parallel and distal to the elbow or knee. Paraxial deficiencies can be divided into preaxial (radial and tibial), postaxial (ulnar and fibular) and central (cleft hand and foot) deficiencies.
