Spermatogenesis , Spermatogonia
Explanation:
Gonads are the primary sex organs in the male which are the two testes.
Each testis divide into testicular lobules each containing the sparse connective tissue with the endocrine interstitial cells that secrets testosterone, and also contains one to four highly convoluted seminiferous tubules which is responsible for sperm production.
The process is known as <u>spermatogenesis</u>.
This process begins with mitotic division of stem cells which are located close to basement membrane of tubules. The cells are known as <u>spermatogonial stem cell</u>s. The division produces two types of cells.
Type A cells are the cells which replenish stem cells and type B cells are the cells which differentiate into spermatocytes. They have number of chromosomes = 46.

Explanation:
Urinary bladder is the hollow, muscular and distensible (elastic) organ in the urinary system of a human. The urine enters the bladder through the ureters from the kidneys. The urine collected in the bladder expands it.
The urinary bladder is made up of transitional epithelium. Once the urinary bladder is expanded to a certain extent it stimulates the stretch receptors in the transitional epithelium for the excretion of urine through the urethra.
Therefore, when the urine is accumulated in the urinary bladder, the bladder distends or expands and stimulates the stretch receptors in the transitional epithelium for urine excretion.
