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.
THE CAPSULE STAIN. The capsule is a thick polysaccharide layer around the outside of the cell. It is nonionic, so. the dyes that we commonly use will not bind to it. Two dyes, one acidic and one basic, are. used to stain the background and the cell wall, respectively. The area between the 2 dyes is. the halo of the capsule surrounding the cell.
