Caudal cell mass

Caudal cell mass is a structure that forms during the early stages of embryonic development. It is located at the caudal end of the embryo, and plays a crucial role in the formation of the spinal cord, vertebrae, and other structures of the lower body.

Formation

The caudal cell mass forms during the third week of embryonic development. It arises from the primitive streak, a structure that forms at the caudal end of the embryo. The cells of the primitive streak migrate towards the caudal end of the embryo, forming the caudal cell mass.

Function

The caudal cell mass is responsible for the formation of several important structures in the lower body. These include the spinal cord, vertebrae, musculoskeletal structures, and part of the urogenital system. The cells of the caudal cell mass differentiate into these various structures through a process known as cell differentiation.

Clinical significance

Abnormalities in the formation or function of the caudal cell mass can lead to a variety of congenital disorders. These include spina bifida, a condition in which the spinal cord does not fully form, and Caudal regression syndrome, a rare disorder characterized by abnormal development of the lower spine.
