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. Correct! 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 Correct! Correct Answer 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. Correct Answer Correct! 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 Correct! Correct Answer Correct Answer 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) Correct! 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
