By the end of this section, you will be able to:
  • Identify the major glands of the endocrine system
  • Identify the hormones secreted by each gland
  • Describe each hormone’s role in regulating bodily functions

Glands and Hormones

The glands in your body release hormones to help it work properly.

The hypothalamus is an intermediary between the nervous and endocrine systems; it tells the pituitary gland what to do.

The pituitary gland is like the boss of all the other glands.

The thyroid makes thyroxine, which is important for how your body uses energy and grows.

The adrenal glands make hormones that help your body deal with stress.

The pancreas makes hormones that control how much sugar is in your blood.

The ovaries and testes make hormones that affect how much you want to have sex and how you behave.

Endocrine system

The endocrine system is a group of glands that release hormones to regulate the body’s functions.

An example of a behavioral reaction involving the endocrine system is feeling anxious or stressed, which can trigger the release of stress hormones like cortisol from the adrenal glands.

Pituitary

The pituitary gland is like the boss of all the other glands in the body, controlling their secretions.

One example of a behavioral action involving the pituitary gland is regulating growth during puberty, which is controlled by the pituitary gland’s secretion of growth hormone.

Thyroxine

Thyroxine is a hormone produced by the thyroid gland that is essential for basic metabolic processes and growth.

An example of a behavioral action involving thyroxine is feeling energetic and active when the thyroid gland produces the right amount of thyroxine, which regulates metabolism and energy levels.

Why This Matters

The growth and maturity of a pre-teen, teen, and young adult are closely connected to the information about glands and hormones.

During the pre-teen and teen years, the endocrine system undergoes significant changes, releasing hormones responsible for physical growth, sexual development, and emotional changes. Understanding the role of growth hormones, sex hormones, and stress hormones can provide insights into the physical and emotional changes individuals experience during these stages of life.

For pre-teens, the onset of puberty is characterized by the activation of the endocrine system, leading to the production of sex hormones such as estrogen and testosterone. These hormones play a crucial role in developing secondary sexual characteristics and the maturation of reproductive organs.

Teenagers experience rapid physical growth and changes in body composition, which are influenced by growth and thyroid hormones. Additionally, hormone fluctuations can impact mood, behavior, and stress responses during this developmental stage.

As young adults reach full physical maturity, the endocrine system regulates various bodily functions, including metabolism, energy levels, and reproductive health. Hormonal balance is essential for maintaining overall well-being and adapting to the demands of adult life.

Therapists, Teachers, and Parents

Knowing these realities can help behavioral health therapists, teachers, and parents in several ways.

Behavioral health therapists can benefit from this knowledge, as hormones play a significant role in regulating emotions, mood, and stress responses. Being aware of how hormones impact behavior can help therapists better understand and address their clients’ mental health issues.

For teachers, understanding the endocrine system and its effects on behavior can provide insights into students’ learning, social interactions, and emotional well-being. Recognizing the influence of hormones on behavior can help educators create a supportive and understanding environment for their students.

Knowing about glands and hormones can help parents comprehend their children’s emotional and behavioral changes during different stages of development. It can also help parents support their children’s overall well-being and address any behavioral or emotional challenges that may arise.

Summary

The endocrine system is a group of glands that release hormones to regulate the body’s functions. These hormones control things like growth, energy use, and how the body deals with stress. During puberty, the endocrine system undergoes significant changes, releasing hormones responsible for physical growth, sexual development, and emotional changes.

These hormones play a crucial role in developing secondary sexual characteristics and maturing reproductive organs. Understanding how hormones impact behavior and emotions can help therapists, teachers, and parents better support young people during this stage of life.
