Study Notes
Intermediate Mesoderm
Definition
- The intermediate mesoderm is a type of mesoderm that gives rise to the kidneys, adrenal glands, and reproductive organs in mammals.
Origin
- The intermediate mesoderm originates from the lateral plate mesoderm during gastrulation.
- It is situated between the paraxial mesoderm (forms somites) and the lateral plate mesoderm (forms body walls and extremities).
Development
- The intermediate mesoderm differentiates into three main regions:
- Nephrogenic cord: gives rise to the kidneys and urinary system.
- Adrenalogenic region: forms the adrenal glands.
- Gonadal ridge: develops into the reproductive organs (ovaries or testes).
Organogenesis
- The intermediate mesoderm undergoes a process called mesenchymal-epithelial transition, where mesenchymal cells aggregate and form epithelial structures.
- The nephrogenic cord forms the pronephros, mesonephros, and metanephros, which eventually develop into the kidneys.
- The gonadal ridge forms the genital ridges, which differentiate into ovaries or testes.
Significance
- The intermediate mesoderm plays a crucial role in the development of the urinary and reproductive systems in mammals.
- Abnormalities in intermediate mesoderm development can lead to congenital anomalies and diseases affecting the kidneys, adrenal glands, and reproductive organs.
