Hypothalamus releases corticotropin-releasing hormone (CRH) ---> Pituitary gland releases adrenocorticotropic hormone (ACTH) ---> ACTH stimulates the adrenal cortex ---> adrenal cortex releases cortisol into the blood stream ---> cortisol affects target cells, and ceases once homeostasis is reached.
A bacteria, which possesses capsule is a capsulated bacteria. The purpose of capsule staining is to observe bacterial capsule by distinguishing capsular material from the bacteria cell. Principle: In capsule staining, a smear of bacteria is made at the center of a slide.
Some manufacturers will enteric coat capsules. Enteric coating is a polymer barrier on oral supplements. This helps protect supplements from the ph (i.e. acidity) of the stomach. Another substance is called alginate which coats and protects the bacteria until it gets into the small intestine where it is safe.
