(A) The epithelium of the small intestine consists of a series of crypts and villi. Stem and progenitor cells proliferate in the crypts, with their differentiated progeny moving upwards into the villi, where they are eventually shed into the intestinal lumen. (B) The stem cell niche is found at the base of the crypt. Stem cells express high levels of LGR5, and are found intercalated between Paneth cells, a specialized epithelial cell.

Pituitary Gland: Located at the base of the brain, the pituitary gland: regulates and releases important hormones to our body; and plays a big part of our overall well-being. Injury to the pituitary gland may affect: growth in children; blood pressure; fatigue; depression; sex drive; body temperature; and pain.

This is where the amygdala is located in the brain. It is located within the temporal lobes of the brain. It is responsible for processing of memory, decision-making, emotional reactions and is part of the limbic system.
