How cells communicate 1. diffusion- neurotransmitters 2. Hormones- local hormones/ paracrine= same tissue 3. Direct (Gap Junctions)- heart cells Comparing Exocrine and Endocrine Exocrine- releases product into duct/ tube, extracellular effects (pancreas). Endocrine- releases tissue fluid and circulatory system, intracellular effects (thyroid hormones).

Interactions 1. Synergist (production of sperm) 2. Permissive- give another permission to function estrogen- uterus- receptors- for progesterone- glycogen- glucose 1. Antagonistic Effects- Result from Target Cell Alter Metabolism T3, T4 Change mitosis rate Synthesis of new molecule Cell to take in substance Cell to release substance Change permeability

    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.
