Which of the following are functions that hormones regulate?Multiple select question.GrowthSkeletal muscle contractionMetabolismReproduction

Hormones regulate the following functions:

1. Growth: Hormones like the Human Growth Hormone (HGH) secreted by the pituitary gland regulate the growth of the body. They stimulate the growth of bone and body tissues.

2. Metabolism: Hormones like thyroxine and triiodothyronine produced by the thyroid gland regulate the body's metabolism. They control how your body uses energy.

3. Reproduction: Hormones like estrogen, progesterone, and testosterone are crucial in the regulation of the reproductive systems in males and females. They control the menstrual cycle in women, sperm production in men, and are essential for conception and pregnancy.

Skeletal muscle contraction is not typically regulated by hormones. It is primarily controlled by the nervous system. However, hormones can influence muscle function indirectly. For example, insulin affects the uptake of glucose by muscle cells, which can affect energy availability and thus muscle contraction. But the direct regulation of contraction is not a primary role of hormones.
