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.
1 By using the negative staining method demonstration of capsule becomes easy. 2  So in this method first we use congo red stain as it is acidic stain it stain the background in red colour. 3  Further we use Manevalâs stain this stain has four important components and they are-.  10 % FeCl3 â It acts as chemical fixative.
