this layer of the meninges is tightly attached to the brain - correct answer pia mater the ________ fissure separates the right and left cerebral hemispheres. - correct answer median longitudinal describe the function of the brain ventricles - correct answer there are 4 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 all the following are functions of the hypothalamus EXCEPT - correct answer filters out unimportant sensory information what is the largest portion of the brain? - correct answer cerebrum this region of the brain controls decision making skills - correct answer frontal lobe a patient is having difficulty producing speech sounds, but other motor movements are normal. which area of the brain is most likely damaged? - correct answer broca's area what is muscle tone and how is it maintained? - 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. which statement is FALSE concerning the brain stem? - correct answer the midbrain helps to regulate breathing. which of the following is TRUE concerning the cerebellum? - correct answer the anterior lobe receives information from the body trunk. which of the following is most likely a symptom of ALS? - correct answer impaired ability to swallow which of the following is FALSE concerning CV A? - correct answer an ischemic stroke is also known as a "brain bleed" a patient is unable to extend his fourth and fifth digits when asked to open his hand. what is most likely the cause? - correct answer ulnar nerve damage label the following spinal cord regions in the diagram below - correct answer 1: lateral column 3. gray commissure 4: anterior column 6. anterior/ventral horn 11. ventral root what cranial nerve is highlighted in blue? - correct answer oculomotor what type of nerve is the cranial nerve below and what does it control? - correct answer motor: shoulder movement the maxillary branch of the trigeminal nerve: - correct answer receives sensory information from the upper lip and upper gums 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. - correct answer this cranial nerve receives sensory information for smell - correct answer A. olfactory this cranial nerve controls the inferior oblique muscle - correct answer C. occulomotor this cranial nerve has 3 branches - correct answer D. trigeminal this cranial nerve is responsible for taste on the anterior portion of the tongue - correct answer F. facial this cranial nerve is responsible for taste on the posterior portion of the tongue. - correct answer H. glossopharyngeal label the nerves A-C in the figure below: - correct answer a. radial b. ulnar c. median this lumbar plexus is from spinal nerves: - correct answer T12-L04 a patient is on a ventilator post a car accident. what region of the spine is most likely damaged? - correct answer C03-C05 a patient is not able to extend his left wrist or fingers. what nerve is most likely damaged? - correct answer radial a patient sustained damage to their femoral nerve. what is most likely limited? - correct answer hip flexion, knee extension which of the following is true concerning the lumbar plexus? - correct answer there are 3 cords; medial, lateral and posterior these contain the ganglia for the sympathetic nervous system that controls the effector organs in the trunk, head and limbs. - correct answer sympathetic trunk ganglia which of the following is false concerning the sympathetic nervous system? - correct answer it is also called the craniosacral division 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. - correct answer you are trying to increase the activity of the parasympathetic nervous system which is also 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 - correct answer you would be more likely to see paralysis because motor neurons exit the spinal cord anteriorly. one of your patients sustained a hemorrhagic CV A. 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. - 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.
