Q.All are true regarding spinal cord supply
except
a. supplied by the midline anterior spinal artery and two posterolateral spinal arteries
b. artery of Adamkiewicz is found in the thoracolumbar region
c. artery of Adamkiewicz is usually on the left side, between T8 and L1–2
d. The anterior spinal artery supplies the major portion of the cord substance
e. posterolateral spinal arteries supply the motor cells of the anterior horns
ANS.---e
The anterior spinal artery is the most important of supply because it supplies the major portion of the cord substance, including the motor cells of the anterior horns. It gives off tiny sulcocommissural arteries that run into the cord; they are not visible at angiography unless pathologically enlarged.
