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 stains of the Capsule staining technique. Typically an acidic stain such as Congo red or nigrosin, which stains the background, and a basic stain that colorizes the cell proper are used.This technique begins as a negative stain; cells are spread in a film with an acidic stain and are not heat-fixed.
