pitutary gland shows two lobes i.e anterior lobe and posterior lobe. anterior lobe secrets 6 hormones namely GH,LTH,ACTH,FSH,LH,TSH. posterior lobe does not secrete any hormone but it stores hormones secreted by hypothalamic neurons.
There is no hormone to stimulate the production of the parathyroid hormone from pituitary gland. The calcium level is probably have auto regulation.
Pituitary gland
High levels of thyroxine in the blood negatively feedback to the pituitary gland, reducing the secretion of thyroid-stimulating hormone (TSH). Conversely, low levels of thyroxine signal the pituitary gland to increase TSH secretion to stimulate the thyroid gland to produce more thyroxine.
No, the secretion of pituitary hormones is largely controlled by the hypothalamus. The hypothalamus produces releasing and inhibiting hormones that regulate the secretion of hormones from the pituitary gland. The thalamus is primarily involved in relaying sensory information to the cerebral cortex.
The mechanism of transportation from the hypothalamus to the anterior pituitary gland is through a system of blood vessels called the hypothalamic-pituitary portal system, which connects the two structures. Hormones synthesized in the hypothalamus are released into these blood vessels and then travel to the anterior pituitary gland where they can regulate the secretion of pituitary hormones.

Hypothalamus
The Pituitary Gland.
The pituitary gland controls the secretion of growth hormone.
Thyroid secretion hormone is secreted by the thyrotrope cells in d anterior pituitary gland

Puberty is started by a sudden increase in hormones, released by the Pituitary gland.
