  Endocrine System Summary Notes (NEET Biology – Easy Line by Line Explanation)  - Dr.Sanjaykumar pawar 1. Hormones and Their Functions Hormones are special chemical messengers produced by endocrine glands. They help in: Coordination of body activities Regulation of body functions Integration between organs Hormones control: Metabolism Growth Development Reproduction Homeostasis 2. Endocrine System Organs The human endocrine system includes: Hypothalamus Pituitary gland Pineal gland Thyroid gland Adrenal gland Pancreas Parathyroid gland Thymus Gonads: Testis (male) Ovary (female) Other organs also producing hormones: Gastrointestinal tract Kidney Heart 3. Pituitary Gland (Master Gland) Divisions of Pituitary The pituitary gland has 3 parts: (i) Pars distalis (Anterior pituitary) Produces 6 trophic hormones. Trophic hormones regulate other endocrine glands. (ii) Pars intermedia Secretes only one hormone: MSH (Melanocyte Sti...

Diagrammatic representation of the pituitary gland showing anterior pituitary, posterior pituitary, hypothalamus, and hormone secretion. Pituitary Gland (Master Gland) – Easy NEET Notes  - Dr.Sanjaykumar Pawar Introduction The pituitary gland is a small endocrine gland present at the base of the brain. It is called the “Master Gland” because it controls many other endocrine glands. It lies in a bony cavity called Sella Turcica of the skull. The pituitary gland is connected to the hypothalamus by a stalk. Structure of Pituitary Gland The pituitary gland is divided into two main parts: 1. Adenohypophysis (Anterior Pituitary) It is the front part of the pituitary gland. It develops from epithelial tissue. It has two regions: Pars distalis Pars intermedia A. Pars Distalis (Main anterior pituitary) It secretes six important hormones: Hormone Full Form Main Function GH Growth Hormone Body growth PRL Prolactin Milk production TSH Thyroid S...

  Labeled diagram of the human endocrine system showing major endocrine glands and their locations in the body. Human Endocrine System – Easy NEET Notes  By- Dr.Sanjaykumar Pawar What is the Endocrine System? The endocrine system is a group of glands that produce hormones . Hormones are chemical messengers that control body activities. These hormones travel through blood to target organs. Main Function Controls: Growth Metabolism Reproduction Water balance Stress response Sleep cycle Major Endocrine Glands in Human Body 1. Hypothalamus Located in the forebrain below the thalamus. Connects nervous system with endocrine system. Controls pituitary gland. Contains neurosecretory cells that produce hormones. Types of Hypothalamic Hormones A. Releasing Hormones Stimulate pituitary gland to release hormones. B. Inhibiting Hormones Stop secretion of pituitary hormones. Important Examples GnRH (Gonadotropin Releasing Hormone) Stimulates release o...
