Typology: Exams
1 / 10
1. This layer of the meninges is tightly **at- tached to the brain.
D.Cingulate gyrus
6. This region of the brain acts to coordi- nate multiple sources of sensory infor- mation. A. Primary sensory cortex B. Primary motor cortex C. Correct! Association area D.Precentral gyrus E. Postcentral gyrus
7. A patient is having difficulty understand- ing language but is still able to speak fluently. The patient's dermatomes are in- tact. Which area of **the brain is most like- ly damaged?
C. The anterior lobe receives in- formation from the body trunk. D.The vermis coordinates arm movements. A. Occipital lobe B. Frontal lobe
12.Which of the following is false concern- ing a CVA? 13.A patient is unable to extend his fourth and fifth digits when asked to open his hand. What is most likely the cause? 14.Label the following spinal cord regions in the diagram below: 1: 5: 6: 9: 11: 15.What cranial nerve is highlighted in blue (also indicated by the arrow) in the figure below? C. Parietal lobe D.Hippocampus E. Correct! All the above A. Correct! An ischemic stroke is also known as a "brain bleed". B. A TIA is a form of an ischemic stroke. C. Stroke survivors may regain some lost functions through ther- apy. D.A hemorrhagic stroke is due to a broken blood vessel. A. CVA in the frontal lobe B. Carpal tunnel syndrome C. Correct! Ulnar nerve damage C. Anterior spinal cord injury 1: Posterior (Dorsal) column 5: Anterior median fissure 6: Posterior (Dorsal) horn 9: Dorsal root 11: DRG (Dorsal Root ganglion) A. Optic B. Oculomotor C. Trochlear D.Correct! Abducens E. Spinal Accessory
16.What type of nerve is the cranial nerve below and what does it control? (High- lighted in blue, also indicated by the ar- row) 17.Which of the following is true about the trigeminal nerve? 18.Use the figure below to answer the fol- lowing questions. Answer by writing the letter (A-J) from the figure that corre- sponds with the correct cranial nerve. This cranial nerve receives information from the retina. This cranial nerve is responsible for the sensation of the digestive tract. A. Mixed: Sensation of digestive tract and Regulation of heart rate B. Motor: Tongue movement C. Sensory: Hearing/balance D.Correct! Mixed: Facial muscles and Taste A. The mandibular branch re- ceives sensory information from taste buds. B. The ophthalmic branch con- trols eye movements. C. Correct! The maxillary branch receives information from the up- per lip. D.The maxillary branch controls the muscles of mastication.
This cranial nerve controls movement of the eye laterally. This cranial nerve receives sensory in- formation for hearing. This cranial nerve is responsible for vol- untarily moving the tongue. 19.Label the nerves (A-C) in the figure be- low: A: B: C:
Radial B- Ulnar C- Median
D. Correct! C03-C A. Elbow flexion B. Hip extension C. Wrist flexion D.Correct! Wrist extension A. Femoral B. Correct! Sciatic C. Saphenous D.Common fibular nerve 24.24.
Which of the following is true concerning the brachial plexus? 25.These contain the ganglia for the sympa- thetic nervous system that controls the effector organs in the trunk, head and limbs. 26.Which of the following is false concern- ing the parasympathetic nervous sys- tem? 27.A patient comes into the ER following an accident. She is scared and starting to hyperventilate. You talk with her in a A. Roots are located furthest from the spinal cord. B. Correct! There are anterior and posterior divisions. C. Divisions branch next into two cords: anterior and posterior. D.The posterior cord forms the median nerve. A. Correct!Sympathetic trunk ganglia B. Celiac ganglion C. Superiomesenteric ganglion D.Inferior mesenteric ganglion E. Ciliary ganglion A. Primarily contains cholinergic synapses. B. It is also called the cran- iosacral division. C. Correct! Acts to increase the heart rate. D.Promotes the digestion of foods. You are trying to increase the activity of the parasympathetic nervous system as it is also calm, reassuring manner as she receives sometimes called the "house- medical care. You are trying to increase the activity in which division of her ner- vous system? Explain your answer.
28.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 keeper system" because it pro- motes all the internal respons- es we associate with a relaxed state. The parasympathetic sys- tem also acts to slow the heart rate. You would be more likely to see decreased sensation because sensory neurons enter the spinal cord posteriorly.
see paralysis or decreased sensation? Explain your answer. 29.One of your patients sustained a hem- orrhagic CVA. You notice they have rigid movements when moving their arms. They also have difficulty forming a plan The basal ganglia is responsible for executing a motor plan and to slow and control fine movements (creating the rigid movements). to move their body. What area of the brain Apraxia, or impaired motor plan- is most likely impacted? Explain your reasoning. ning. Apraxia results in rigid movements and difficulty execut- ing a motor plan.
