- A 25-year-old soldier suffers a gunshot wound on the lower part of his back and is unable to move his legs. A neurologic examination and magnetic resonance imaging (MRI) scan reveal injury of the cauda equina. No other dysfunction is noted. Damage to the following structure could explain the inability to move his legs: ventral primary rami at spinal cord level T2. O True FalseA 25-year-old soldier suffers a gunshot wound on the lower part of his back and is unable to move his legs. A neurologic examination and magnetic resonance imaging (MRI) scan reveal injury of the cauda equina. No other dysfunction is noted. Damage to the following structure could explain the inability to move his legs: ventral roots of the lumbar spinal nerves. O True FalseMike is a 34-year old male who reports to the ER after a motorcycle accident. MRI results show that he transected (cut across) the spinal cord between T1 and L1. Which of the following best describe his condition? O paraplegia O hemiplegia quadriplegia O spinal shock only O none of the above Next « Previous

What part of the spinal cord is likely injured?The actions of posterior fibers of Deltoid are.. . O Extension and external rotation of the shoulder. O Flexion and medial rotation of the shoulder. O Flexion and external rotation of the shoulder. A Extension and medial rotation of the shoulder.List the number and locations of the 31 pairs of spinalnerves
- John Jones injured his spinal cord. He has use of his serratus anterior muscle, biceps brachii, and deltoid. However, he does not have movement in most muscles of his hand and digits 4 and 5. Where is his spinal cord injury?Nurse Marina is conducting Maternal and Child Lecture series to College of Nursing students. The anatomy of the spinal cord and dural space is important when giving regional spinal anesthesia. At what approximate spinal level do the dural space and spinal cord, respectively, end? L5, T12 T10,TB S2, L2 SS, S2 L2, T10For each statement about the anatomy of the spinal cord, determine whether it is True or False. The spinal cord (in adults) ends around the L1 or L2 vertebrae. True Spinal nerves leave the spinal True column between two adjacent vertebrae. There are 31 total spinal nerves. False False Cerebrospinal fluid flows through the central canal of the spinal cord.
- All of the following vertebral structures are anterior to the spinal cord except the: posterior longitudinal ligament vertebral bodies supraspinous ligament intervertebral disks O anterior longitudinal ligament Question 3 The atlas articulates with the axis and: the skull O the sacrumWatch this short video (http://openstaxcollege.org/l/facialnerve) to see an examination of the facial nerve usingsome simple tests. The facial nerve controls the musclesof facial expression. Severe deficits will be obvious inwatching someone use those muscles for normal control.One side of the face might not move like the other side. Butdirected tests, especially for contraction against resistance,require a formal testing of the muscles. The muscles of theupper and lower face need to be tested. The strength testin this video involves the patient squeezing her eyes shutand the examiner trying to pry her eyes open. Why does theexaminer ask her to try a second time?Internal arcuate fibers and medial lemniscus fibers refer to one and the same fibers moving in a circular direction. TRUE OR FALSE
