9/8/2016 Test 1 | Evernote Web Test 1 Quizlet: https://quizlet.com/147086637/test1flashcards/ Chapter 16 Which of the following cranial nerves does NOT carry taste impulses to the brain?: trigeminal nerve (FGV Do) What is the first event that results in vision in rods? : light hits rod cells The specialized cell extensions of hair cells that will stimulate neurons for hearing are called : flagella Where are the ear stones found?: labyrinth, a cavity in the temporal bone, is divided into three sections: the vestibule, the semicircular canals, and the cochlea Correct sequence in the propagation of sound waves through the ear 1. Auricle 2. External acoustic meatus 3. Tympanic membrane 4. Malleus 5. Incus 6. Stapes 7. Oval Window 8. Perilymph of Scala vestibuli 9. Endolymph of cochlear canal 10. Basilar membrane 11. stereocilia 12. Perilymph scala of tymponi 13. round window The oval window is connected directly to which passageway? : scala vestibuli of the cochlea Given these areas of the retina, 1. macula 2. fovea centralis 3. optic disc 4. periphery of the retina.: 2,1,4,3 Which structure is part of the fibrous layer of the eye? sclera All of the following are correct: Cochlea hearing vestibule static equilibrium semicircular canals angular or dynamic rotation Loudness of sound has to do with amplitude or intensity of sound waves and of hair cells stimulated whereas pitch is determined by the frequency of the sound waves. Static Equilibrium is detected in the vestibule Dynamic or rotational equilibrium is detected by the saccule and utricle and in the semicircular canals. The process of blood cell formation is called : Hematopoiesis. Red blood cells transport carbon dioxide bound to the : amino groups of the globin protein. What will the kidneys releases In response to low oxygen levels in the blood? : Insulin Which of the following leukocytes releases histamine and heparin? : basophil What white blood cell's main function is to attack parasitic worms?: eosinophil Which pathway of blood clotting involves factor X, factor V, platelet phospholipids, and Ca2+?: Intrinsic A floating blood clot that breaks loose from inside a blood vessel is called a(n) : embolus What condition may develop when a Rhnegative mother has a second Rhpositive fetus? : Both erythroblastosis fetalis and hemolytic disease of the newborn are correct. https://www.evernote.com/Home.action#n=e939165a3686407cbe9f4c372fc93ff1&b=7fa5e844aacc4853bd15626a4c458d58&ses=4&sh=1&sds=1/4 9/8/2016 Test 1 | Evernote Web Chapter 18 http://info.visiblebody.com/bid/249678/learnheartanatomyvesselsvalvesandchambersohmy Red blood cells have a ___ : nucleus A person with type A blood: will have a transfusion reaction if given type B blood, has anti B antibodies , has type A antigens One of the functions of eosinophils is to: attack parasitic worms. Basophils usually play a bigger role in: allergic reactions. What regulates RBC production?: erythropoietin Erythropoietin: is a hormone that enhances erythropoiesis by stimulating the formation of proerythroblasts and the release of reticulocytes from bone marrow. What triggers erythropoietin production by the kidneys: decreased blood oxygen platelets are cell fragments of a cell in bone marrow known as: a megakaryocyte When does Rh factor present a problem?: When mother is Rh negative and baby is positive. It could result in hemolytic disease of a newborn. Both extrinsic and intrinsic lead to the common pathway which starts with activation of Factor X which converts prothrombin to thrombin and in turn. How does fibrin work?: converts fibrinogen to fibrin to form the patch clot over the platelet plug. Fibrin is NOT a clotting factor If a thrombus or undesirable clot forms it can lead to: an embolus if it breaks from the vessel where it formed. This is dangerous because it can cause an infarct or blockage if this happens in the lung, brain or heart the consequences are very serious! There may be times the patients you see may have this as a concern. Chapter 19 ESV=EDVSV SV= EDVESV End Systolic Volume= End diastolic volume stroke volume Cardiac output (CO) Amount of blood pumped by a single ventricle in one minute Heart rate (HR) : number of beats per minute Stroke volume (SV) : volume of blood ejected during one beat HR x SV = CO E.g., at rest HR 75 beats/min; SV 70 mL/beat CO = 5250 mL/min (5.25 L/min) Total blood volume about 5 L total blood volume pumped through circulation every minute FrankStarling Law: as volume increases,the heart wall increases resulting in increased stroke volume https://www.evernote.com/Home.action#n=e939165a3686407cbe9f4c372fc93ff1&b=7fa5e844aacc4853bd15626a4c458d58&se2/4&sh=1&sds=5& 9/8/2016 Test 1 | Evernote Web plateau phase: in cardiac muscle electrical activity is due to extracellular Ca entering the cardiac muscle cell which keeps membrane potential close to 0 mv for an extended period plateau phase: triggers sarcoplasmic reticulum to release additional Ca which is needed for contraction. The cardiac action potential is __ and contraction is ___ than skeletal muscle!: longer and stronger Equation to calculate the SV: ESVEDV Equation for Cardiac output: (CO)= Stroke volume(SV)x Heart rate(HR) parasympathetic stimulation plays a role at rest in keeping the heart rate between: 60 70. Normal heart rate: 90100 bpm. What initiates the heart beat? : SA node! Your knowledge of the information on chronotropic: speed up heart rate ionotropic: slow down heart rate for stroke volume. Which are the two arteries that carry blood away from the heart? : pulmonary trunk and aorta Which vessels bring blood into the right atrium? : superior vena cava and inferior vena cava are veins that return deoxygenated blood from circulation in the body and empty into the right atrium Which of the following vessels does NOT bring blood into the right atrium? : coronary sinus The left ventricle pumps blood into the : pulmonary veins Which valve separates the left ventricle and the aorta? : aortic semilunar valve When the ventricles contract : the atrioventicular valves close and the semilunar valves open. Which of the following is the correct flow of blood as blood moves from the body, through the heart, to the lungs? :Blood enters the right atrium from the superior and inferior venae cavae, and the coronary sinus. 2. From right atrium, it goes through the tricuspid valve to the right ventricle. 3. From the right ventricle, it goes through the pulmonary semilunar valves to the pulmonary trunk 4. From the pulmonary trunk it moves into the right and left pulmonary arteries to the lungs. 5. From the lungs, oxygenated blood is returned to the heart through the pulmonary veins. 6. From the pulmonary veins, blood flows into the left atrium. 7. From the left atrium, blood flows through the bicuspid (mitral) valve into the left ventricle. 8. From the left ventricle, it goes through the aortic semilunar valves into the ascending aorta. 9. Blood is distributed to the rest of the body (systemic circulation) from the aorta. Sequence of structures in the heart’s conduction system : SA node, AV node, bundle of HIS, Purkinje figers https://www.evernote.com/Home.action#n=e939165a3686407cbe9f4c372fc93ff1&b=7fa5e844aacc4853bd15626a4c458d58&ses=4&sh=1&sds=53/4 9/8/2016 Test 1 | Evernote Web https://www.evernote.com/Home.action#n=e939165a3686407cbe9f4c372fc93ff1&b=7fa5e844aacc4853bd15626a4c458d58&ses=4&sh=1&sds=5& 4/4
