This is the most superficial layer of the brain meninges.
Your Answer: pia mater Dura mater (menix) Question 2
The _______ fissure separates the right and left cerebral hemispheres. Your Answer: median longitudial Median longitudinal Question 3
What is the purpose of the blood-brain barrier? Describe its maintenance from a cellular level. Your Answer: prevents most particles from entering the central nervous system. It keeps the brain separated from the spinal cord for blood circulation The blood-brain barrier is a diffusion barrier which prevents most particles from entering the central nervous system tissue, keeping the brain and spinal cord separate from general blood circulation. The blood-brain barrier is formed by the relatively impermeable brain capillaries, due to the glial cells astrocytes. Maintenance of the blood-brain-barrier is important to provide a stable chemical environment for the nervous system. Question 4
All the following are functions of the hypothalamus except : Maintain homeostasis Controls the pituitary gland
Correct! Association area Precentral gyrus Postcentral gyrus Question 7
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 Correct! Wernicke’s area Occipital lobe Parietal lobe Primary sensory cortex Question 8
Describe how memories are stored and retrieved in the brain. Include a specific brain region. Your Answer: (cerebral hemispheres) The hippocampus is a memory center and helps with memory storage Memories are not stored in one specific area within the brain but instead are stored throughout the cerebral hemispheres. The hippocampus acts as a memory center to help with memory storage and retrieval. The involvement of the limbic system explains why emotionally charged events result in our most vivid memories. Question 9
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. Correct! The midbrain helps to regulate breathing. Question 10
Which of the following is false concerning the cerebellum? The gray matter is external while the white mater is internal.
Which of the following is false concerning a CVA? Correct! An ischemic stroke is also known as a “brain bleed”. A TIA is a form of an ischemic stroke. Stroke survivors may regain some lost functions through therapy. A hemorrhagic stroke is due to a broken blood vessel. Question 13
A patient is unable to extend his fourth and fifth digits when asked to open his hand. What is most likely the cause? CVA in the frontal lobe Carpal tunnel syndrome Correct! Ulnar nerve damage Anterior spinal cord injury
Question 14
Label the following spinal cord regions in the diagram below: 1: _____________________ 3: _____________________ 4: _____________________ 6: _____________________ 11: ____________________ Your Answer:
You Answered Abducens Spinal Accessory Question 16
What type of nerve is the cranial nerve below and what does it control? (Highlighted in blue, also indicated by the arrow) Correct!
Motor: Shoulder movement Motor: Eye movement Sensory: Hearing/balance Mixed: Tongue movement and taste Question 17
Which of the following is true about the trigeminal nerve? The mandibular branch receives sensory information from taste buds. The ophthalmic branch controls eye movements. Correct! The maxillary branch receives information from the upper lip. The maxillary branch controls the muscles of mastication. Question 18
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.
Label the nerves (A-C) in the figure below: A: _________________ B: _________________ C: _________________
Your Answer: A. Lateral Femoral Cutaneous B. Femoral Nerve C. Saphenous A- Lateral femoral cutaneous B- Femoral nerve C- Saphenous Question 20
Question 22
A patient is not able to extend his left wrist or fingers. What nerve is most likely damaged? Ulnar Axillary Correct! Radial Median Question 23
A patient has decreased sensation over the posterior surface of the thigh. What nerve is most likely damaged? Femoral Correct! Sciatic Saphenous Common fibular nerve
Question 24
Which of the following is true concerning the brachial plexus? Roots are located furthest from the spinal cord. Correct Answer There are anterior and posterior divisions. You Answered Divisions branch next into two cords: anterior and posterior. The posterior cord forms the median nerve. Question 25
These contain the ganglia for the parasympathetic nervous system that target the intrinsic eye muscles to change the diameter of the pupil. You Answered Sympathetic trunk ganglia Pterygopalatine ganglion Superiomesenteric ganglion Intramural ganglia
Your Answer: Decreased sensation - the neurons enter the spinal cord posteriorly You would be more likely to see decreased sensation because sensory neurons enter the spinal cord posteriorly. Question 29
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: Basal ganglia and apraxia Basal ganglia helps movements while apraxia forms a pkan to move the body 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. Quiz Score: 78 out of 100
Question 1
This layer of the meninges is tightly attached to the brain. Your Answer: pia mater Pia mater (menix) Question 2
The _______ fissure separates the right and left cerebral hemispheres. Your Answer: median longitudinal fissure Median longitudinal Question 3
Describe the function of the brain ventricles. Your Answer: set of communicating cavities 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
All the following are functions of the hypothalamus except : Regulates sleep Links the nervous and endocrine systems Correct!
