Thyroxine -hormone stimulates metabolic rate
Thyroid
Sympathetic nerves through the cervical ganglia.
BUT, release of hormones-by the Pituitary gland

Thyroid AND Parathyroid
Parathyroid hormone – regulates calcium and phosphorus levels.
Parathyroid

Largest
Lobular surface
Thyroid
Endocrine
Encapsulated
Smooth surface
Parathyroid
___ hormones which stimulate maturation of
T-lympho-cytes and WBC
Thymus
Branches of X (Vagus) nerve and cervical spinal nerves.
Thymus
Blood SUPPLY:
Inferior thyroid, internal thoracic arteries.
Return by veins in the posterior surface of the gland
Thymus
Drains: within the gland
Thymus
Part of the immune system.
T-lympho-cytes, WBC mature in the gland.
After puberty the gland stop growing and start to shrink
Thymus
