Study Notes
Endocrine System Overview
- The endocrine system, like the nervous system, controls and regulates bodily functions.
- It primarily governs processes that happen slowly, such as growth.
- The endocrine system uses hormones to send signals throughout the body.
- Hormones take longer to produce an effect than signals sent by the nervous system.
Hormones
- Hormones are chemicals released into the bloodstream by glands.
- They affect cell and tissue activity throughout the body.
Pituitary Gland
- Often called the "master gland," it controls other endocrine glands.
- It regulates growth, metabolism, reproduction, and stress responses.
- Located at the base of the brain.
Pituitary Gland - Oxytocin
- Stimulates uterine contractions during childbirth.
- Promotes bonding and trust.
- Application: Encourages bonding in relationships, breastfeeding, and emotional connection.
Pituitary Gland - Vasopressin
- Regulates water balance by reducing urine production.
- Application: Staying hydrated, managing conditions like diabetes insipidus.
Pituitary Gland - Growth Hormone
- Stimulates growth, cell repair, and metabolism.
- Application: Promotes recovery after exercise, supports muscle growth, addresses growth disorders.
Adrenocorticotropic Hormone (ACTH)
- Stimulates cortisol production in the adrenal glands to help the body respond to stress.
- Application: Stress management techniques reduce cortisol overproduction.
Pituitary Gland - Prolactin
- Prompts milk production in breastfeeding mothers.
- Application: Breastfeeding mothers rely on this hormone to nurse effectively.
Luteinizing Hormone (LH)
- Triggers ovulation and stimulates testosterone production.
- Application: Supports fertility treatments and menstrual cycle tracking.
Follicle-Stimulating Hormone (FSH)
- Stimulates egg development in ovaries and sperm production in testes.
- Application: Important in fertility evaluations and treatments.
Thyroid
- Located in the front of the neck, wrapped around the trachea (windpipe).
- Regulates metabolism, energy, and calcium balance.
Thyroxin (T4)
- Regulates metabolism and energy.
- Application: Monitoring thyroid health for weight management and energy regulation.
Calcitonin
- Lowers blood calcium levels by inhibiting bone resorption.
- Application: Used to manage osteoporosis or high calcium levels.
Parathyroid
- Located in the neck, within the thyroid gland.
- Regulates calcium and phosphorus levels in the blood and bones.
Parathyroid Hormone (PTH)
- Increases blood calcium levels by stimulating bone resorption and calcium absorption.
- Application: Manages calcium imbalances and bone health.
Thymus Gland
- Located in the upper chest, between the lungs, and behind the breastbone.
- Crucial for immune system development during childhood.
Thymus Gland - Thymosin
- Stimulates T-cell production for immune function.
- Application: Supports immunity through nutrition and health maintenance.
Adrenal Glands
- Located in the epigastrium at the top of the kidneys.
- Produce hormones that regulate stress responses, metabolism, and electrolyte balance.
Adrenaline
- Also known as epinephrine; a hormone released by the adrenal gland into the bloodstream.
- Targets vital organs, allowing the body to respond quickly in critical situations.
- Application: Understanding its role in emergency responses and stress management.
Pancreas
- Located between the kidneys and aids in digestion.
- Regulates blood sugar.
Insulin
- Lowers blood sugar by promoting glucose uptake into cells.
- Application: Essential for diabetes management through monitoring and insulin therapy.
Glucagon
- Raises blood sugar by promoting glucose release from the liver.
- Application: Used in managing hypoglycemia, especially for diabetics.
Testes
- Located in the scrotum in the lower abdomen (singular: testis).
- Produce sperm and male sex hormones.
Testosterone
- Produced by the testes.
- Controls developmental changes in males like deeper voice, libido, facial and pubic hair, and increased muscle and bone strength.
Androgen
- Promotes male sexual development, muscle growth, and libido.
- Application: Managing conditions like low testosterone levels or supporting athletic performance.
Ovaries
- Located on either side of the uterus in the lower abdomen (singular: ovary).
- Produce eggs and female sex hormones.
Estrogen
- Produced by the ovaries.
- Controls developmental changes in females like breast development and the release of eggs, marking the start of menstruation.
Progesterone
- Supports pregnancy and regulates the menstrual cycle.
- Application: Used in fertility treatments and managing menstrual disorders.
