Case Study#1-Overheated:ACasestudyonSkeletal MusclePhysiology Time to scrub in," says Dr. Hodges. The appendectomy you are about to observe is your second surgical case in surgical technician school. The patient, David Sims, is an 18-year-old male who was healthy until two days ago when he began having severe abdominal pain, fever, and vomiting resulting in a diagnosis of appendicitis. David is in excellent health and has never had surgery before, so you anticipate the procedure to go smoothly. Your instructor asked the anesthesiologist, Dr. Hodges, if you can observe her today during the procedure."A of the patient's vital signs and lab work are within normal limits so we are good to go," says Dr. Hodges as David is brought into the operating room. You help get David ready by applying the heart monitor, oxygen saturation monitor, and blood pressure cuff. After David has been sedated, Dr. Hodges places a special tube down his esophagus to measure his core body temperature and another in his trachea (an endotracheal tub to help him breathe during the procedure. While Dr. Hodges places the endotracheal tube, she comments, "His jaw muscles are a bit tight so it is very important to check and record his vital signs every 10 minutes. T is your job today while I monitor his respiratory status." The case has been in progress for about 20 minutes when you notice David's heart rate jump up to 120bpr setting off the ECG alarm on the monitor. You are concerned and ask, "Can he feel what is happening? His heart rate just went up." Dr. Hodges looks at you and asks, "What is his core temperature?" You show he chart and see that David's temperature has gradually begun to rise and is now 101.8° F (38.8° C). Dr. Hod face turns serious and she says, "His exhaled carbon dioxide levels have also begun to rise. We need to ge malignant hyperthermia cart right away!"

2,a-cistern of sarcotubular system stores calcium in muscle cell

b-when action potential reaches DHPR(dihydropyridine receptor is a calcium channel)it undergoes conformational changes which open The(Ryanodine receptor).it causes the ca ions to come out of sarcoplasmic reticulum into the sarcoplasm

3,ca ion binds to Troponin C.it causes a confirmational change causing Tropomyosin to slide and expose active site which results in contraction
