Types of hormones and their function?

Answer 1

Primarily produced in your endocrine glands, hormones manage and control everything in your body. From your immune response to your energy output, it regulates your blood-sugar level, maintains the critical balance among your body's electrolytes, and enables you to build strong healthy bones, it determines how you mature and how slowly or quickly you age. Because of them, women are able to become pregnant and carry a baby. It helps you digest and assimilate your food, convert it into energy, and then use the energy to build muscles or burn fat. And remarkably, your endocrine system monitors not only what is going on inside you but also what's going on around you. It interprets what you see and experience and translates it into physical reactions in your body, enabling you to adapt to change and to cope with stresses of all kinds.

1. Thyroid hormones: Insulin, Adrenaline, Calcitonin
2. Sex hormones: Estrogen, Progesterone, Testosterone, Dehydroepiandrosterone (DHEA)
3. Pineal hormone: melatonin

Testosterone is found in men, oestrogen in women,

Answer 2

Primarily produced in your endocrine glands, hormones manage and control everything in your body.

1. Thyroid hormones: Insulin (blood sugar level), Adrenaline (fight or flight response), Calcitonin (calcium metabolism)
2. Sex hormones: Estrogen & Progesterone (monthly cycle regulation), Estrogen & Testosterone (libido), Dehydroepiandrosterone or DHEA (muscle mass)
3. Pineal hormone: melatonin (sleep)

Answer 3

The essence of multicellularity is the coordinated interaction of the various kinds of cells that make up the body. Cells communicate with each other by chemical signals.

Three kinds of chemical signaling can be distinguished;

• autocrine - the cell signals itself through a chemical that it synthesizes and then responds to. Autocrine signaling can occur
  • solely within the cytoplasm of the cell or
  • by a secreted chemical interacting with receptors on the surface of the same cell
• paracrine - chemical signals that diffuse into the area and interact with receptors on nearby cells. Examples are:
  • The release of cytokines that cause an inflammatory response in the area.
  • The release of neurotransmitters at synapses in the nervous system.
• endocrine - the chemicals are secreted into the blood and carried by blood and tissue fluids to the cells they act upon.

Answer 4

Known as one of the body's master glands, the thyroid is located at the base of the neck near the Adam's apple. Its primary purpose is to produce hormones that regulate the metabolism.

When the thyroid receives thyroid stimulating hormone (TSH) from the pituitary gland it produces triiodothyronine which is commonly referred to as T3, thyroxine which is commonly known as T4, and calcitonin. These are the general categories of thyroid hormones.

If the thyroid is producing too much or too little thyroid hormones, physical symptoms will emerge. The best way to test these hormones is through various thyroid blood tests, ordered by a physician. If you have any questions or concerns regarding your thyroid health talk to your doctor.
