CSCC Human Physiology Exam 2 Questions And Answers Rated A+

1st degree AV Nodal Block - the AV node is having difficulty getting the action potentials on through to the rest of the conduction system. See prolonged PR intervals 2nd degree AV Nodal Block - there is even more difficulty than in first degree. 3rd degree AV Nodal Block - even more serious than second degree. See many Ps without QRS complexes, AP not getting through at all A bands - contain mainly thick filaments Abstract memory - Type of Explicit memory, Fact memory ( learning facts, like the names of bones Active filling - atria contract and send the rest of the blood from them into the ventricles Aerobic Metabolism - this is the way to make ATP using oxygen, long term muscle activity Amino Acid Based - Can't enter the cells and so their target cells have receptors on the cell surface. Uses second messengers (cAMP, DAG or Inositol Triphospate) Anaerobic Metabolism - the way to make ATP quickly bu it is inefficient, short, quick muscle activity Analog to Broca's Area - involved in the ability to recognize emotion in speech (if someone is angry when they are talking to you) Analog to Wernike's Area (non-dominant Hemisphere) - involved in the recognition of symbols, patterns, faces, etcAnterior Pituitary - controls other endocrine glands. It secretes TSH (controls the thyroid gland), ACTH (controls the adrenal cortex), and FSH & LH (controls the ovaries or testes) AP also secretes Prolactin and growth hormone ATP - this is the cells for of energy Atrial diastole - the atria are relaxed and are filling with blood Atrial Systole - contraction of the atria Atrioventricular Node (AV) - this is found at the junction between the atria and the ventricles and it delays the impulse for a fraction of second and allows the atria to contract before the ventricles get the message. Autocrine Secretions - local chemicals, act short distances on themselves Barorecptors - pressure receptors which detect the BP and send information to the cardiovascular centers in the medulla oblongata. Found in the carotid arteries and the aortic arch. Basal Ganglia - gets info from cerebrum and from muscles Basal Metabolic rate - the metabolic rate when rested comfortable and fasted for 12 hours. The energy the body needs just to exist Broca's Area (Dominant Hemisphere) - responsible for articulation of speech (making the words come out of your mouth). If this area is damaged, the person knows what he wants to say but can't say it (he can however write it down) Calcitonin - comes from the thyroid gland and is released when there are increased blood calcium levels, acts to decrease blood calcium levels by causing the calcium to be deposited into bonesCardiac conduction system - system consists of electrically excitable cells(they have action potentials all on their own) which will cause the heart to beat, even if all other nerves to the heart are cut. Cardiac output - volume of blood put out by the heart each min. Cardiovascular System - Gas Transport, Nutrient Transport, Waste Transport Cerebellum - the main coordinator of movement 3 sensory sources: eyes, vestibular apparatus in the ears, and the joints and tendons Changes in Maximum Capacity - due to the number of crossbridges formed within the muscle. CO=HR x SV - Cardiac output equals heart rate times stroke volume Congenital Hypothyroidism - found in children with developmental disabilities and dwarfism as well as regular hypothyroidism symptoms, a form of edema in the face causing a sad look to the face. Consolidation - this is the process by which short term memories become long term memories Consolidation of Abstract Memory - involves rehearsal (going over it again and again) Consolidation of Episodic Memory - occurs by remembering the event Cortisol - found in the adrenal cortex also is glucorticoid and means it affects the metabolism of glucose Creatine Phosphate - this molecule, which is present in muscle cells can give a phosphate group to ADP to make ATPDeep Q Wave - if seen, the person may have previously had a heart attack Diabetes - no insulin made, or no insulin receptors. Glucose can't enter the cells, high blood sugar Diastole - relaxation of filling phase Early Diastole - ventricles relax, ventricular pressure decreases, blood in the aorta and pulmonary arteries back flows toward the heart. Semilunar valves closed
