Module 2 exam portage learning (Questions and Answers A+ Graded 100% Verified) This layer of the meninges is tightly attached to the brain ANS: pia mater the ________ fissure separates the right and left cerebral hemispheres. ANS: median longitudinal describe the function of the brain ventricles ANS: 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 ANS: filters out unimportant sensory information what is the largest portion of the brain? ANS: cerebrum this region of the brain controls decision making skills ANS: 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? ANS: broca's area what is muscle tone and how is it maintained? ANS: 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? ANS: the midbrain helps to regulate breathing. which of the following is TRUE concerning the cerebellum? ANS: the anterior lobe receives information from the body trunk. which of the following is most likely a symptom of ALS? ANS: impaired ability to swallow which of the following is FALSE concerning CV A? ANS: 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? ANS: ulnar nerve damage label the following spinal cord regions in the diagram below ANS: 1: lateral column 3. gray commissure 4: anterior column 6. anterior/ventral horn 11. ventral root what cranial nerve is highlighted in blue? ANS: oculomotor what type of nerve is the cranial nerve below and what does it control? ANS: motor: shoulder movement the maxillary branch of the trigeminal nerve: ANS: 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. ANS: this cranial nerve receives sensory information for smell ANS: A. olfactory this cranial nerve controls the inferior oblique muscle ANS: C. occulomotor this cranial nerve has 3 branches ANS: D. trigeminal this cranial nerve is responsible for taste on the anterior portion of the tongue ANS: F. facial this cranial nerve is responsible for taste on the posterior portion of the tongue. ANS: H. glossopharyngeal label the nerves A-C in the figure below: ANS: a. radial b. ulnar c. median this lumbar plexus is from spinal nerves: ANS: T12-L04 a patient is on a ventilator post a car accident. what region of the spine is most likely damaged? ANS: C03-C05 a patient is not able to extend his left wrist or fingers. what nerve is most likely damaged? ANS: radial a patient sustained damage to their femoral nerve. what is most likely limited? ANS: hip flexion, knee extension which of the following is true concerning the lumbar plexus? ANS: 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. ANS: sympathetic trunk ganglia which of the following is false concerning the sympathetic nervous system? ANS: 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. ANS: 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 ANS: 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. ANS: 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.
