Name: Dr.__________________________________________ AP Biology: Diagnosis of Endocrine Disorders As an endocrinologist, you have the important job of correctly identifying your patients? endocrine disorders and also prescribing a treatment plan. Review each of the set of symptoms displayed by the 6 Patients below. Use your knowledge of the endocrine system to diagnose which disease the patients have. You can then think about a treatment plan for each patient to help them feel better again. Take notes in the patient charts below. Patient Symptoms Diagnosis Endocrine Gland/ Hormone Involved Treatment Plan #1: 22 yo female extreme fatigue a round, red face extra fat deposits on the back of neck irregular menstrual cycle #2: 55 yo male

Cell Biology Objectives and Worksheet 2: Cell-to-Cell and Signal Transduction Name____________________ Objectives: Write out material in your course notebook. Cell to cell communication and signal transduction. Distinguish among types of cell-to-cell communication {autocrine, paracrine, endocrine, cytokine, cell surface markers, neurotransmitter} List major classes of receptors. Explain or diagram the specific structural components of the types. List and describe the components of signal transduction and the molecules involved. Write out specific second messenger signal transduction pathways (see tables 6.1 & 6.2). Define each of the following and predict their effect on signal transduction: agonist and antagonist for one receptor

Concept 11.1 Local Signaling Cells may communicate by direct contact Animal cells Gap junctions Cell junctions Plant cells Plasmodesmata between cell plants Signaling substances can pass freely between adjacent cells Cell?cell recognition Paracrine signaling Short distances One cell can secrete some chemical or molecule that can then act on neighboring cells Example growth factors Stimulate adjacent cells to grow and divide Synaptic signaling Nerve cells in brain from one cell to another mostly an electrical signal Electrical signal triggers release of neurotransmitter Long distance signaling Endocrine signaling Hormones travels in bloodstream Target cell specifically binds hormone 3 stages of cell signaling 1 reception signaling molecule will combine to receptor

Mica Piro Chapter 11: Cell Communication External Signals are Converted to Responses Within the Cell (11.1) Evolution of Cell Signaling One topic of sell ?conversation? is sex?a type of yeast cell identify their mates by chemical signaling 2 sexes: a and ? Each type secretes a specific factor that binds to receptors only on the other type of cell When exposed to each other?s mating actors, a pair of cells of opposite type change shape, grow toward each other, and fuse/matethe new a/? cell contains all the genes of both original cells Once received by the yeast cell surface receptor, a mating signal is changed, or transduced, into a form that brings about the response of mating, which occurs in a series of steps called a signal transduction pathway

Brendan Knob 8/21/13 AP Bio: Summer Essay Spring The human body is like a machine. When all of its parts are working properly and you take care of it, it runs perfectly, when you don?t it starts to break down. The ?control center? of the human body is the nervous system. Another key player in the communication in the body is the endocrine system. These two systems allow your body to function.
