Hormones are chemical messengers of specialized tissues that are carried by the blood system to influence other cells, tissues and organs or glands. They work at a steady pace, slowly and affect many body functions including metabolism, sexual function reproduction, and emotional balance.
The endocrine system is the system in control of coordinating the relationship between the body’s organs and hormones. It is a very important system in the body as it works to be able to produce hormones, control your body’s hormonal level and circulate it all through your body. The endocrine system is made up of many glands, such as the pituitary gland, thyroid gland, thymus gland adrenal gland, pancreatic gland etc.
The pituitary gland is termed the “master gland“ because it is the gland responsible for the transmission of information from the brain to other glands in the body.
The pituitary gland is a two-part gland, with anterior and posterior parts. The anterior pituitary gland secrets classical hormones such as the growth hormones and tropic hormones. The posterior pituitary secretes neurohormones which are made in the hypothalamus, e.g. vasopressin and oxytocin since it doesn’t produce its own hormones.
