Study Notes
Endocrine System Overview
- The pituitary gland is considered the 'master gland' or 'master regulator' of metabolism.
- The connection between the pituitary gland and the hypothalamus is called the hypophyseal portal system.
Pituitary Gland Functions
- The anterior lobe of the pituitary gland secretes growth hormone.
- Growth hormone is responsible for growth and development.
Hormone Characteristics
- Peptide hormones cannot be taken orally because they are broken down in the digestive system.
- Peptide hormones have a rapid onset of action and a short duration of action.
- Steroid hormones need to be bound to a carrier protein to be transported in the blood.
- Steroid hormones have a long duration of action.
Pancreas and Diabetes
- The primary role of the pancreas is to regulate blood sugar levels in relation to diabetes.
- The islets of Langerhans in the pancreas produce hormones to regulate blood sugar levels.
- When the body is unable to produce enough insulin, it leads to diabetes.
- The term 'diabetes mellitus' refers to a group of metabolic disorders characterized by high blood sugar levels.
- The primary sex hormones produced by the reproductive organs are estrogen and testosterone.
Hormone Regulation
- The hypothalamus produces releasing hormones to induce the release of another hormone.
- The negative feedback loop is an example of a feedback loop in the endocrine system.
- Hormones can act on neighbouring endocrine cells (paracrine action) or on the cell of origin (autocrine action).
- Homeostasis is the maintenance of physiological equilibrium.
Thyroid Gland
- The primary role of the thyroid gland is to regulate metabolism.
- Iodine is essential for thyroid hormone production.
- Hyperthyroidism is characterized by symptoms such as weight loss, anxiety, and rapid heartbeat.
- The main difference between acromegaly and gigantism is the timing of excessive growth hormone production.
Other
- The adrenal medulla produces epinephrine and norepinephrine.
- Insulin is typically administered through injection or infusion.
- The gonads produce sex hormones that regulate the menstrual cycle.
