Cerebellum

A key brain structure made up mainly of nerve tissue, the cerebellum is not a tissue type in and of itself. It plays a role in motor learning, posture, balance, and voluntary movement coordination.

This tissue is the early connective tissue that is derived from the embryo’s mesoderm layer. It supports and integrates cells and organs during development and is the precursor of many of the body’s mature connective tissues.

A single layer of cube-shaped cells with central nuclei is known as simple cuboidal epithelium. Its primary functions are absorption, secretion, and protection; it lines thyroid follicles, gland ducts, and kidney tubules.
