BIOD 152 EXAM 2
• A patient comes into the ER following an accident. she is scared and starting to
hyperventilate. You talk with her in a calm, reassuring manner as she receives medical care.
You are trying to increase the activity in which division of her nervous system? Explain
Answer: You are trying to increase the activityof the parasympathetic nervous system as it is
also known as the "housekeeper system" because it promotes all the internal responses we
associate with a relaxedstate. The parasympathetic symptom also acts to slow the heart rate.
• If someone sustains an injury to the area of the spinal cord, as shown byblue oval, would
you be more likely to see paralysis or decreased sensation?Explain
Answer: You would be more likely to see paralysis (muscular weakness) becausemotor
neurons exit the spinal cord anteriorly.
• One of your patients sustained a hemorrhagic CVA. Yu notice they haverigid movements
when moving their arms.They also have difficulty forminga plan to move their body. What
area of the brain is most likely impacted? Explain your reasoning.
Answer: The basal ganglia is responsible for executing a motorplan and to slow and control
fine movements (creating the rigid movements).
Apraxia, or impaired motor planning. Apraxia results in rigid movements and difficultyexecuting
a motor plan.
• This layer of the meninges is tightly attached to the brain
Answer: Pia Mater (menix)
• The fissure separates the right and left cerebral hemispheres-
Answer: Median longitudinal
• Describe the function of the brain ventricles
Answer: There's 4 ventricles in the interiorof the brain, chambers filled with CSF which is
produced there. Once formed, the CSF circulates through the ventricles and into the
subarachnoid space bathing andfloating in the brain
• All of the following are functions of the hypothalamus except
Answer: Links thenverous and endocrine systems
• What is the largest portion of the brain
Answer: CerebeLLUM
• This region of the brain controls decision making skills
Answer: Frontal lobe
