The spinal cord of the sheep has a ________orientation.
a. vertical
b. transverse
c. horizontal
d. sagittal
Introduction:
The spinal cord is a part of the central nervous system. It is a thin, long, and tubular structure which is made up of nervous tissue. It extends from the medulla oblongata present in the brainstem to the vertebral column’s lumbar region. Its main function is to connect the PNS to the brain.
Answer to Problem 1PL
Correct answer:
Option (c), horizontal.
Explanation of Solution
Explanation/justification for the correct answer:
Option (c) is horizontal. The spinal cord in sheep is placed horizontally as per its body structure. Hence, this option is correct.
Explanation for incorrect answer:
Option (a) is vertical. The spinal cord in humans is placed vertically not in sheep. Hence, this option is incorrect.
Option (b) is transverse. In sheep, the spinal cord is placed horizontally. Hence, this option is incorrect.
Option (d) is sagittal. The spinal cord in sheep is placed horizontally as per its body structure. Hence, this option is incorrect.
