Question 2 0 / 3 pts Question 3 4 / 4 pts This layer of the meninges is tightly attached to the brain. Your Answer: pia meter Pia mater (menix) The fissure separates the cerebrum from the cerebellum. Your Answer: median longitudinal Transverse What is the purpose of the blood-brain barrier? Describe its maintenance from a cellular level. Question 7 2 / 2 pts Cerebellum Occipital lobe Temporal lobe Primary sensory cortex A patient is having difficulty producing speech sounds, but other motor movements are normal. Which area of the brain is most likely damaged? Broca’s area Wernicke’s area Occipital lobe Parietal lobe Primary motor cortex Question 9 2 / 2 pts What is muscle tone and how is it maintained? Your Answer: Muscle tone is maintained with dopamine Muscle tone is the degree at which muscles remain partially contracted while at rest. Muscle tone is continuously monitored and maintained by the cerebellum to keep bones and joints in place. Which statement is false concerning the brainstem? The midbrain portion of the brainstem is continuous with the spinal cord. The pons helps to regulate breathing. The midbrain contains the superior and inferior colliculi. The medulla contains reflex centers to regulate vasoconstriction. Question 8 2 / 2 pts Question 11 0 / 2 pts Which of the following is true concerning the cerebellum? The gray matter is internal while the white mater is external. The cerebellum works to plan body movements by relaying information spinal cord. Correct Answer The anterior lobe receives information from the body trunk. The vermis coordinates the trunk and shoulder movements. Which of the following is most likely a symptom of ALS? Correct Answer Question 10 0 / 2 pts 3: 4: 6: 11: Your Answer: Question 15 0 / 3 pts 1. right hemispere 3. pons 4. parietal 6. 11. 1: Lateral Column 3: Gray Commissure 4: Anterior Column 6: Anterior/Ventral Horn 11: Ventral Root What cranial nerve is highlighted in blue (also indicated by the arrow) in the figure below? Optic Correct Answer Oculomotor Question 17 4 / 4 pts Question 18 0 / 10 pts Mixed: Tongue movement and taste The maxillary branch of the trigeminal nerve: receives sensory information from the eyebrows receives sensory information from the upper lip and upper gums is a mixed sensory and motor branch controls the muscles of mastication Use the figure below to answer the following questions. Answer by writing the letter (A- J) from the figure that corresponds with the correct cranial nerve. 1. This cranial nerve receives information from the retina. 2. This cranial nerve is responsible for the sensation of the digestive tract. 3. This cranial nerve controls movement of the eye laterally. 4. This cranial nerve receives sensory information for hearing. 5. This cranial nerve is responsible for voluntarily moving the tongue. Your Answer: 1. 2. 3. 4. 5. 1. B. (Optic) 2. I. (Vagus) 3. E. (Abducens) 4. G. (Vestibulocochlear) Question 20 2 / 2 pts Question 21 0 / 2 pts A-Radial B- Ulnar C- Median The lumbar plexus is from spinal nerves: T12-L04 L04- S04 C01-C05 L01-S01 Question 22 0 / 2 pts A patient is on a ventilator post a car accident. What nerve is most likely damaged? Radial Correct Answer Phrenic Sciatic Median A patient damaged the radial nerve. What action is most likely limited? Elbow flexion Hip extension Wrist flexion Question 23 2 / 2 pts Question 24 0 / 2 pts Correct Answer Wrist extension A patient has decreased sensation over the posterior surface of the thigh. What nerve is most likely damaged? Femoral Sciatic Saphenous Common fibular nerve Which of the following is true concerning the lumbar plexus? Question 28 0 / 5 pts Your Answer: Trying to increase the activity of the parasympathetic system because it promotes internal responses we associate with a relaxed state and helps decrease or slow down the patients heart rate. You are trying to increase the activity of the parasympathetic nervous system as it is also sometimes called the “housekeeper system” because it promotes all the internal responses we associate with a relaxed state. The parasympathetic system also acts to slow the heart rate. If someone sustains an injury to the area of the spinal cord, as shown below by the blue oval, would you be more likely to see paralysis or decreased sensation? Explain your answer. Question 29 0 / 5 pts Your Answer: Decreased sensation due to it being near the parietal area which is in control of sensory information such as touch and pain. Sensory neurons enter the spinl cord posteriorly You would be more likely to see paralysis (muscular weakness) because motor neurons exit the spinal cord anteriorly. One of your patients sustained an ischemic CVA. You notice that their gait is very unsteady. It almost appears as if they are intoxicated. What portion of the brain was most likely affected by the stroke? Explain your answer. Your Answer: The basal ganglia due to unsteady gait. The basal ganglia executes motor plan and can slow or ontrol fine motor movements. The cerebellum was most likely affected as it is responsible for coordinating body movements including gait.
