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.
India ink staining: the capsule appears as a clear halo around the bacterium as the ink can't penetrate the capsule. : 87 Maneval's capsule stain: the capsule appears as a clear halo between the pink-stained bacterium and the bluish-grey stained background.
