Your Answer: True Answer: True Question 2 Not yet graded / 5 pts List the phases of an action potential in order. Your Answer: Step one - Resting potention Step two - Depolarization Step three - Repolarization Step four - Resting condition Answer: 1) Resting potential 2) Depolarization 3) Repolarization 4) Afterpolarization Question 3 Not yet graded / 5 pts True or False; If false, explain why the statement is false: The central nervous system consists of the brain and spinal cord. Your Answer: True Answer: True Match the following lobes of the brain with the correct function. ou Answered Temporal Correct Answer Contains sensory areas for hearing and smelling Correct! Frontal ou Answered Parietal Correct Answer Receives sensory information from body receptors Correct! Occipital Question 5 5 / 5 pts Correct! Question 6 Not yet graded / 5 pts Describe the function of the parasympathetic nervous system. Your Answer: The parasympathetic nervous system calms the body and conserve energy. It is also known to be responsible for rest and digest responses Answer: The parasympathetic system is also sometimes called the “housekeeper system” because it promotes all the internal responses associated with a relaxed state. Parasympathetic stimulation causes the pupil of the eye to constrict and helps the lenses of the eyes to focus on nearby objects. It promotes the digestion of food through stimulation of the smooth muscles of the GI tract and secretion of digestive glands to assist digestion, such as the salivary glands. The parasympathetic system also acts to slow the heart rate. Question 7 0 / 5 pts ou Answered orrect Answ Question 8 Not yet graded / 5 pts Explain the main steps in the process of hearing. Your Answer: Step 1 - sound wave enters the outter ear via the auricle Step 2 - sound wave travel through the external auditory Step 3 - sound wave vibrates the tympanic membrane (ear drum) Step 4 - the vibrations then vibrates the auditory ossicles in the middle ear, which then amplifies the sound Step 5 - waves are transfered to the oval window, causing cochlear fluid to vibrate like nerve cells Step 6 - Vibration travels throughthe cochlear duct to the vestibulochochlear nerve Step 7 - A nerve impulse is sent to the temporal lobe of the brain Answer: First, sound waves are funneled into the external auditory canal causing the eardrum to vibrate. The vibrations transmit to the ossicles, which push against fluid inside the cochlear duct. The movement of the fluid causes movement of the stereocilia in the organ of Corti. The movement of the stereocilia then stimulates the neurons to send impulses through the cochlear nerve to the primary auditory cortex of the temporal lobe. Question 9 Not yet graded / 5 pts Which cells serve as stem cells in the gustatory system that divide and differentiate into new supporting cells that then form new gustatory cells? Your Answer: Basal cells Answer: Basal cells Question 10 Not yet graded / 5 pts Fill-in-the-blanks: The two upper receiving chambers of the heart are called the , while the two lower pumping chambers are called the . Your Answer: The right and left atria; The right and left ventricle Answer: atria; ventricles nanswered Correct! nanswered Fill-in-the-blanks: The circuit of the heart sends deoxygenated blood to the lungs to be oxygenated, while the circuit sends the oxygenated blood from the heart to the cells of the body. Your Answer: Answer: pulmonary, systemic Correct! nanswered Answer: False; The lymphatic system does not include the pancreas. Question 16 Not yet graded / 5 pts Fill-in-the-blanks: The innate immune system is a defense system, while the adaptive immune system is a more immune system response. Your Answer: Nonspecific; Answer: generalized OR nonspecific; targeted OR specific Question 17 Not yet graded / 5 pts True or False; If false, explain why the statement is false: Neutrophils, eosinophils, basophils and monocytes are capable of phagocytosis. Your Answer: False Answer: True Question 18 Not yet graded / 5 pts An accumulation of too much fluid in tissues can cause localized swelling called edema. Lymphedema is a specific form of edema. Explain what occurs in lymphedema. Your Answer: Sever cases of lymphedema can affect the ability to move the affected lymph and also increase skin infection and sepsis and skin break down Answer: The lymphatic system is not functioning properly to return fluid back into circulation. A lymph vessel can become blocked, or the lymph nodes can be removed in an area for testing, causing difficulty with lymph drainage. The interstitial fluid slowly accumulates in the limb (arm or leg), and it becomes extremely swollen and distended. Lymphedema can become a serious condition if not treated because the swollen tissues are vulnerable to infection. If left untreated the connective tissues and vessels become permanently stretched and distended. ou Answered Correct! Correct! Correct! Correct! Question 20 Not yet graded / 5 pts Label the parts of the male reproductive system below (Letters A-D) and describe the role of C. Your Answer: A. Vas deferens B. Penis C. Epididymis - It transports sperm from the testis to the vas deferens D. Testis Answer: A. Vas deferens B. Penis C. Epididymis, The role of the epididymis is the location of sperm maturation D. Testis. Question 21 Not yet graded / 5 pts True or False; If false, explain why the statement is false: The testes are involved in the production of progesterone and estrogen. Your Answer: False. it only produces sperm and testoteron Answer: False; The ovaries are involved in the production of progesterone and estrogen OR The testes are involved in the production of testosterone. Question 22 Not yet graded / 5 pts Fill-in-the-blanks: Pregnancy begins with the fertilization of an egg by a sperm forming a . It spends about 3-4 days undergoing mitosis in the oviducts forming the and another 3-4 days undergoing mitosis while unattached in the uterus, forming the as the endometrium prepares for implantation. Your Answer: Zygote; Plastocytes; Answer: zygote, morula, blastocyst Question 23 Not yet graded / 5 pts True or False; If false, explain why the statement is false: Both the male and female urinary systems are comprised of 2 kidneys, 2 ureters, 1 bladder, and 1 urethra. Your Answer: True Answer: True Question 24 Not yet graded / 5 pts Short Answer: Which of the following statements is incorrect regarding the kidney? Explain why the statement is incorrect. a) The kidney is bean-shaped. b) The kidney is roughly the size of a can of soup. c) The kidney lies between vertebral levels T12-L3. d) The left kidney lies slightly lower than the right kidney. Your Answer: A. Yes B. Yes C. Yes D. No. The right kidney lies 2-8cm lower than the left Answer: d) The right kidney lies slightly lower than the left kidney due to the location of the liver just above it. Question 25 Not yet graded / 5 pts Define the process of micturition. Be sure to discuss the typical bladder capacity (mL), as well as at least 2 aspects of its design that allows for accommodation of larger volumes of liquid. Your Answer: Micturition is the act of emptying the bladder. When the bladder is full of urine, generally the stretch receptors triggers the process of micturition reflex, and the muscle that surround the bladder also contract. Answer: Micturition is the act of emptying the bladder or urination. As urine accumulates, the rugae flatten and the wall of the bladder thins as it stretches, allowing the bladder to store larger amounts of urine without a significant rise in internal pressure. Thin muscular wall stretches and thins Rugae (folds in the bladder wall) also extend to help accommodate increased capacity Moderately full bladder holds 500 ml of urine but can max out at around 1000 ml nanswered Question 27 Not yet graded / 5 pts True or False; If false, explain why the statement is false: There are three major chemical buffer systems in the body that are fast-acting, generally responding within seconds to help maintain pH homeostasis. Your Answer: True Answer: True Question 28 Not yet graded / 5 pts Your patient has the following blood serum values: pH = 7.2, PCO2 = 37 mm, HCO3- = 21 mEq/L a. Is the patient in acidosis or alkalosis? b. Is the cause respiratory or metabolic? c. Is the condition being compensated? d. If the condition is being compensated, what action is the body taking? Your Answer: A. Alkalosis B. Respiratory C. No, normal D. Hyperventilation from panic attack Answer: a. Acidosis (pH < 7.35) b. PCO2 is in the normal range (between 35-45), so this is not respiratory acidosis, but HCO3- < 22, so this is caused by the metabolic system c. PCO2 is normal – therefore the condition is NOT being compensated by the respiratory system. d. No compensation occurring Quiz Score: 21.5 out of 140 [Show More]
