Question

Enlarged area of the spinal cord from which nerves to the shoulder and upper limbs arise.

B) lumbar enlargement
C) thoracic region
D) conus medullaris

Accepted Answer

The cervical enlargement is the region of the spinal cord where the nerves to the shoulder and upper limbs arise. The other options do not relate to nerves of the upper limbs. The lumbar enlargement is associated with nerves to the lower limbs, the thoracic region contains nerves for the chest and abdomen, the conus medullaris is the tapering end of the spinal cord, and the sacral region contains nerves for the pelvic region and lower limbs.
