Study Notes
Thyroid Gland Function
- Endocrine gland, one of the larger ones in the body.
- Two primary functions relating to thyroid hormone secretion.
- Maintains optimal tissue metabolism.
- Stimulates oxygen consumption in most body cells.
- Regulates lipid and carbohydrate metabolism.
- Influences body mass and mental function.
Thyroid Dysfunction Consequences
- Consequences vary based on the life stage of dysfunction.
- Absence or underactivity (hypofunction) during fetal/neonatal periods can lead to profound mental retardation and dwarfism.
- Thyroid is not crucial for survival in adulthood.
