Endocrine Glands Those glands which secrete their secretion

Endocrine Glands: “Those glands which secrete their secretion into the blood and blood carries its secretion to the target cells”.

Classical Endocrine glands:

Todays question: Obesity is more common in Females than in males. Why?

1). Hypothalamus: Part of forebrain Present in 3 rd ventricle of brain below thalamus It is known as master gland Hormones are called neuro hormones Functions of hypothalamus: 1. It regulates internal environment of the body through autonomic nervous system. It controls heart beat, body temperature, water and salts balance etc. 2. As a endocrine gland it control secretion of pituitary gland by secreting different hormones.

Hormones of Hypothalamus: GHRH (Growth hormone releasing hormone). All cells of body Hypothalamus Stimulate Growth GHRH GH stimulate Anterior Pituitary + +

Hormones of Hypothalamus: GHIH (Growth hormone Inhibiting hormone). All cells of the body Hypothalamus GHIH GH inhibit Anterior Pituitary _ Inhibit growth _

Hormones of Hypothalamus: CRH (Corticotropin releasing hormone). Hypothalamus inhibit _ Adrenal gland stimulate CRH ACTH stimulate Anterior Pituitary + +

Hormones of Hypothalamus: TSHRH (thyroid stimulating hormone releasing hormone). Hypothalamus inhibit _ Thyroid gland stimulate TSHRH TSH stimulate Anterior Pituitary + +

Hormones of Hypothalamus: Gn. RH (Gonadotropin releasing hormone). Hypothalamus Gonads stimulate + FSH Gn. RH LH stimulate + + Anterior Pituitary +

Hormones of Hypothalamus: Gn. IH (Gonadotropin Inhibiting hormone). It is antagonist to Gn. RH Hypothalamus Gonads stimulate _ FSH Gn. IH LH stimulate _ _ Anterior Pituitary _

Hormones of Hypothalamus: PRF (Prolactin releasing factor). Hypothalamus PRF Prolactin stimulate + Anterior Pituitary +

Hormones of Hypothalamus: PIF (Prolactin Inhibiting factor). Hypothalamus PIF Prolactin stimulate _ Anterior Pituitary _
