True or false: the spinal cord (in adults) ends around L1 or L2 vertebrae.
True or false: spinal nerves leave the spinal column between two adjacent vertebrae.
True or false: there are 31 total spinal nerves.
True or false: cerebrospinal fluid flows through the central canal of the spinal cord.
An 18-year-old male is shot in the back and is taken to the emergency room. A neurological exam
reveals a hemisection of the right half of the spinal cord extending from T8 to T12. Which of the
following deficits will most likely result from this injury?
Loss of pain and temperature sensation from the left arm and leg; loss of conscious proprioception from the
right arm and leg; extreme weakness of right arm and leg
O Loss of pain and temperature sensation from the right leg; loss of conscious proprioception from the left leg;
extreme weakness of left leg
O Loss of pain and temperature sensation from the left leg; loss of conscious proprioception from the right leg;
extreme weakness of right leg
Loss of pain and temperature sensation from the right arm; loss of conscious proprioception from the left arm;
extreme weakness of left arm
O Loss of pain and temperature sensation from the left arm; loss of conscious proprioception from the right arm;
extreme weakness of right arm
Complete transection of the spinal cord produces all of the following effects, except :-a- permanent loss of all sensations mediated by the cord below level of lesionb- permanent loss of voluntary movements by muscles innervated by the cord below level of lesionc- permanent loss of reflexes mediated by the cord below level of lesiond- temporary loss of micturition reflexes
