Explanation / Answer
1-Paracrine hormones
The answer is B-act on the neighboring cell
Paracrine and autocrine hormoes are the types of endocrines, those two restricted to cytoplasm of cells. Paracrines works on neighbouring cells where as autocrines works in cells which are produced by them.
2-Which gland is divided into two distinct functional units?
The answer is B-Pituitary
Those are anterior and posterior pitutary glands. Each glands prodcues hormones.
3- All the following hormones are produced and secreted by the ovaries EXCEPT______.
The answer is B-FSH.
FSH - Follicle stimulating hormone - Which is prodcued by anterior piutatary gland. In controls the menustral cycle and production of egges from ovaries in females. In males it controls the production of sperm.
4-Which type of anterior pituitary cell secretes human growth hormone?
The answer is E- Somatotrophs - Those are the cells in anterior piutary glands, these prouces GH or growth hormone...as the somatotrophos produces GH it is also reffered as Somatotropin. Hypothalamus control the the production of somatotropin.
