BIOD 152 Module 2 EXAM.
This is the most superficial layer of the brain meninges - ANSWERDura Mater
(Menix)
This layer of the meninges is tightly attached to the brain. - ANSWERPia
mater (Menix)
The _______ fissure separates the right and left cerebral hemispheres. -
ANSWERmedian
The ______ fissure separates the cerebrum from the cerebellum. -
ANSWERTransverse
Describe the function of the brain ventricles. - ANSWERThere 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.
What is the purpose of the blood-brain barrier? Describe its maintenance
from a cellular level. - ANSWERThe 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.

All the following are functions of the hypothalamus except: - ANSWERRelays sensory impulses to the cerebrum This ventricle is located anterior to the cerebellum. - ANSWERfourth What is the largest portion of the brain? - ANSWERCerebrum This region of the brain acts to coordinate multiple sources of sensory information. - ANSWERAssociation area This region of the brain controls decision making skills - ANSWERFrontal lobe A patient is having difficulty understanding language but is sill able to speak fluently. The patient's dermatomes are intact. Which area of the brain is most likely damaged? - ANSWERWernicke's area A patient is having difficulty producing speech sounds, but other motor movements are normal. Which area of the brain is most likely damaged? - ANSWERBroca's area Describe how memories are stored and retrieved in the brain. Include a specific brain region. - ANSWERMemories 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. What is muscle tone and how is it maintained? - ANSWERMuscle tone is the degree at which muscles remain partially contracted while at rest. Muscle

What cranial nerve is highlighted in blue (also indicated by the arrow) in the figure below? - ANSWERAbducens What cranial nerve is highlighted in blue (also indicated by the arrow) in the figure below? - ANSWEROculomotor What nerve is the cranial nerve below and what does it control? (highlighted in blue, and also indicated by the arrow) - ANSWERMotor: Shoulder movement What type of nerve is the cranial nerve below and what does it control? (Highlighted in blue, also indicated by the arrow) - ANSWERMixed: Facial muscles and Taste Which of the following is true about the trigeminal nerve? - ANSWERThe maxillary branch receives information from the upper lip. 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. - ANSWER1. This cranial nerve receives information from the retina(OPTIC, b) 2. This cranial nerve is responsible for the sensation of the digestive tract (VAGUS, i) 3. This cranial nerve controls movement of the eye laterally (ABDUCENS, e) 4. This cranial nerve receives sensory information for hearing (VESTIBULOCHLEAR, g) 5. This cranial nerve is responsible for voluntarily moving the tongue (HYPOGLOSSAL, j) Use the figure below to ANSWER the following questions. ANSWER by writing the le!er (A-J) from the figure that corresponds with the correct cranial nerve.

  • ANSWER1. This cranial nerve receives sensory information for smell.(OLFACTORY, a) 2. This cranial nerve controls the inferior oblique

muscle (OCULOMOTOR, c) 3. This cranial nerve has three branches( TRIGEMINAL, g) 4. This cranial nerve is responsible for taste on the anterior portion of the tongue (FACIAL, f) 5. This cranial nerve is responsible for taste on the posterior portion of the tongue (GLOSSOPHARYNGEAL, h) Label the nerves (A-C) in the figure below: (pelvis) - ANSWERA: Lateral Femoral Cutaneous Nerve B: Femoral Nerve C: Saphenous Nerve Label the nerves (A-C) in the figure below: (Arm) - ANSWERA-Radial B- Ulnar C- Median The lumbar plexus is from spinal nerves: - ANSWERT12-L The sacral plexus is formed from spinal nerves: - ANSWERL04-S A patient is on a ventilator post a car accident. What region of the spine is most likely damaged? - ANSWERC03-C A patient is on a ventilator post a car accident. What nerve is most likely damaged? - ANSWERphrenic A patient damaged the radial nerve. What action is most likely limited? - ANSWERwrist extension A patent is not able to extend his left wrist or fingers. What nerve is most likely damaged? - ANSWERRadial

receives medical care. You are trying to increase the activity in which division of her nervous system? Explain your ANSWER. - ANSWERYou 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. - ANSWERYou would be more likely to see paralysis (muscular weakness) because motor neurons exit the spinal cord anteriorly. One of your pa#ents 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. - ANSWERThe cerebellum was most likely affected as it is responsible for coordinating body movements including gait. One of your pa"ents 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. - ANSWERThe 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.
