The Hypothalamus
Hypothalamus forms the basal part of the diencephalon( forebrain) that regulates various body functions. Nuclei, which are neurosecretory cells, also produce hormones. They regulate the synthesis and secretion of the Pituitary gland. Hypothalamus produces two types of hormones,
- Releasing Hormones (which stimulate secretion of pituitary hormones) Example- Gonadotropin hormone
- Inhibiting Hormones (which inhibit secretions of pituitary hormones). Example – Somatostatin hormone inhibits the release of growth hormone.
Hormones after being produced, pass through the axon and are released through the nerve endings. They regulate the function of the anterior pituitary Gland. The posterior pituitary is directly under the control of the Hypothalamus.
NCERT Notes for Class 11 Biology Chapter 19: Chemical Coordination and Integration
NCERT Notes Biology Class 11 Chapter 19 Chemical Coordination and Integration: The study of chemical coordination and Integration forms an important part of human physiology. Chemical coordination, integration, and regulations in the human body are carried out by special chemicals called hormones. Regulation, growth, and development of our organs, the endocrine glands, and cells are carried out by hormones.
Here, in Chapter 19 of Biology Class 11 NCERT Chemical Coordination and Integration, we will study the Human endocrine system, Hormones, and their mechanism of action.
