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.
A capsule is a discrete detectable layer of polysaccharides deposited outside the cell wall. A less discrete structure or matrix which embeds the cells is a called a slime layer. The capsule, can be found in both Gram-negative bacteria and Gram-positive bacteria.
