Topic: Endocrine system Reading: Chapter 37 Main concepts : Hormones are a form of cellular communication. Some, such as prostaglandins, are for immediate cell-to- cell communication. Hormones produced by the endocrine system target multiple sites in the body, and generally travel through the bloodstream. Two major types of hormones: Protein hormones: interact with receptors on surface of target cells, and set off a series of reactions within the cell. Lipid hormones: usually enter the cell and are directly involved in activities. The hypothalamus is the master controller of the endocrine system Hypothalamus receives information from the thalamus about the state of the body. Hypothalamus signals the pituitary to send messages to other glands. Pituitary releases hormones that signal other endocrine glands to produce their hormones. Some pituitary hormones themselves have a direct effect. In addition to the endocrine glands, other organs produce some hormones: stomach, kidneys, heart, thymus gland, intestines.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
