Based on your knowledge of ANS receptors, explain how beta blockers are able to manage conditions such as hypertension (high blood pressure)? The Beta 1 cells found in the heart muscle fibers cause excitation. The excitation of the cardiac muscle fibers then causes stronger heart beat, increased heart rate and force on contraction. beta blockers are used to block these beta 1 cells and thus slow down cardiac output. Slower Cardiac output and slower, less forceful contraction against arterial walls can lower blood pressure. Mr. Hernandez visited his doctor complaining that he is constantly thirsty and is “in the bathroom day and night” relieving his bladder. The doctor ordered blood and urine tests to check for glucose and ketones, which were all negative. What is the doctor's diagnosis of Mr. Hernandez, and what gland(s) or organ(s) is(are) involved? It almost sounds like Diabetes, maybe not enough of the Antidiuretic hormone circulating through the blood. Mr. Hernandez's posterior pituitary Gland is not secreting an sufficient amount of the ADH hormone. Amanda hates her new student ID photo. Her hair looks dry, the extra weight that she's gained shows, and her neck looks fat. In fact, there's an odd butterfly shaped swelling across the front of her neck, under her chin. Amanda's also been feeling very tired and mentally “dull” lately, but she figures all new A&P students feel that way. Should she visit the clinic or just wear turtlenecks? Amanda may be having thyroid problems, I am assuming from the description that she may have the start of a goiter. Low levels of thyroid hormone in the blood can cause a release or overabundance of Thyroid-Stimulating Hormone (TSH) in thus causing the thyroid gland to become enlarged.

    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.
