Document Content and Description Below

• A&P II Exam Module 2 Exam Question 1 3 / 3 pts This layer of the meninges is tightly attached to the brain. Your Answer: Pia- mater Pia mater (menix) Question 2 3 / 3 pts The fissure... separates the cerebrum from the cerebellum. Your Answer: The transverse fissure Transverse Question 3 4 / 4 pts Describe the function of the brain ventricles. Your Answer: Brain ventricles ARE 4 and are found inside the brain and filled with CSF. 2 laterals and 3rd and 4th ventricles all of them drain in the central canal of the spinal cord and contains CSF; their main function it is where the CSF is made which helps to absorb impacts when the brain faces them for any activity or movements There are four ventricles in the interior of the brain, chambers filled with cerebrospinal fluid which is produced there. Once formed the CSF circulates through the ventricles and into the subarachnoid space bathing and floating the brain. Question 4 2 / 2 pts All the following are functions of the hypothalamus except: Maintain homeostasis Controls the pituitary gland Links the nervous and endocrine systems Correct! Relays sensory impulses to the cerebrum***** Question 5 2 / 2 pts This ventricle is located anterior to the cerebellum. Lateral Medial Third Fourth Question 6 2 / 2 pts This region of the brain controls decision making skills. Frontal lobe Cerebellum Occipital lobe Temporal lobe Primary sensory cortex Question 7 0 / 2 pts A patient is having difficulty understanding language but is still able to speak fluently. The patient’s dermatomes are intact. Which area of the brain is most likely damaged? Broca’s area Wernicke’s area Occipital lobe Parietal lobe Primary sensory cortex Question 8 1 / 2 pts What is muscle tone and how is it maintained? Your Answer: It is manage by the sensory muscles spindles which work with the stretching of the muscles; it helps to maintain muscles contraction. It is crucial for creating reflexes help with the postures and the equilibrium Correct answer 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. Question 9 2 / 2 pts Which statement is false concerning the brainstem? The medulla portion of the brainstem continuous with the spinal cord. The medulla contains reflex centers to regulate vasoconstriction. The midbrain contains the superior and inferior colliculi. The midbrain helps to regulate breathing. Question 10 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. The anterior lobe receives information from the body trunk. The vermis coordinates the trunk and shoulder movements. Question 11 2 / 2 pts Alzheimer’s disease impacts which region(s) of the brain? Occipital lobe Frontal lobe Parietal lobe Hippocampus All the above Question 12 0 / 2 pts Which of the following is true concerning a CVA? An ischemic stroke is also known as a “brain bleed”. A TIA is a form of hemorrhagic stroke. Stroke survivors never regain any lost function. A hemorrhagic stroke is due to a broken blood vessel. Question 13 0 / 2 pts A patient has decreased hand strength in her right hand. She also has numbness in her first three digits. What is most likely the cause? Spinal cord injury Carpal tunnel syndrome Ulnar nerve damage CVA in the parietal lobe Question 14 8 / 10 pts Label the following spinal cord regions in the diagram below: 1: 5: 6: 9: 11: Your Answer: 1. Post Column of the White matter 5. Ant Median FIssure 6. Post horn of the Gray matter 9. Dorsal root 11. Spinal Nerve Correct answer 1: Posterior (Dorsal) column 5: Anterior median fissure 6: Posterior (Dorsal) horn 9: Dorsal root 11: DRG (Dorsal Root ganglion) Question 15 3 / 3 pts What cranial nerve is highlighted in blue (also indicated by the arrow) in the figure below? Optic Oculomotor Trochlear Abducens Spinal Accessory Question 16 3 / 3 pts What type of nerve is the cranial nerve below and what does it control? (Highlighted in blue, also indicated by the arrow) Motor: Shoulder movement Motor: Eye movement Sensory: Hearing/balance Mixed: Tongue movement and taste Question 17 0 / 4 pts 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 Question 18 4 / 10 pts 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 sensory information for smell. 2. This cranial nerve has three branches. 3. This cranial nerve is responsible for taste on the anterior portion of the tongue. 4. This cranial nerve is responsible for taste on the posterior portion of the tongue. Your Answer: 1. A Olfactory 2. B 3. D 4. Fascial H 5J Glosof. 1. A. (Olfactory) 2. C. (Oculomotor) 3. D. (Trigeminal) 4. F. (Facial) 5. H. (Glossopharyngeal) Question 19 10 / 10 pts Label the nerves (A-C) in the figure below: A: B: C: Your Answer: A Lateral femoral Cutaneous B Femoral nerve C Sapheneous A- Lateral femoral cutaneous B- Femoral nerve C- Saphenous Question 20 2 / 2 pts The sacral plexus is formed from spinal nerves: L04- S04 T12-L04 C01-C05 L01-S01 Question 21 2 / 2 pts A patient is on a ventilator post a car accident. What region of the spine is most likely damaged? L01-L05 S01-S05 T01-T12 C03-C05 Question 22 0 / 2 pts A patient is not able to extend his left wrist or fingers. What nerve is most likely damaged? Ulnar Axillary Radial Median Question 23 0 / 2 pts A patient sustained damage to their femoral nerve. What is most likely limited? Sensation over the medial thigh Sensation over posterior thigh Hip flexion, knee extension Hip extension, Knee flexion Question 24 0 / 2 pts Which of the following is true concerning the lumbar plexus? It arises from L2-S2 spinal nerves. There are three cords: medial, lateral and posterior There are two divisions: anterior and posterior. The anterior division forms the femoral nerve. (F) Question 25 3 / 3 pts These contain the ganglia for the sympathetic nervous system that controls the effector organs in the trunk, head and limbs. Sympathetic trunk ganglia Celiac ganglion Superiomesenteric ganglion Inferior mesenteric ganglion Ciliary ganglion Question 26 0 / 3 pts Which of the following is false concerning the sympathetic nervous system? It is also called the thoracolumbar division. It is also called the craniosacral division. The primary neurotransmitter is norepinephrine. It inhibits the digestive tract. Question 27 0 / 4 pts If you were hiking in the woods and came across a mountain lion, which division of your nervous system would have increased activity? Explain your answer. Your Answer: Correct answer The sympathetic nervous system would have increased activity as it is responsible for preparing our bodies to respond to stressful situations. Question 28 0 / 5 pts 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. Your Answer: You would be more likely to see decreased sensation because sensory neurons enter the spinal cord posteriorly. Question 29 0 / 5 pts One of your patients sustained a hemorrhagic CVA. You notice they have rigid movements when moving their arms. They also have difficulty forming a plan to move their body. What area of the brain is most likely impacted? Explain your reasoning. Your Answer: Correct answer The basal ganglia is responsible for executing a motor plan and to slow and control fine movements (creating the rigid movements). Apraxia, or impaired motor planning. Apraxia results in rigid movements and difficulty executing a motor plan. [Show More]
