Question

1. which term best describes the region of the highlighted bone?

a. sacral
b. gluteal
c. thoracic
d. lumbar

Explanation:

The highlighted bone region in the skeletal diagram corresponds to the sacral area (the sacrum, part of the pelvis and lower spine). The sacral region is associated with the sacrum bone, while gluteal refers to the buttock muscles (not a bone region), thoracic is the chest - spine region, and lumbar is the lower back (above sacral). So the term that best describes the highlighted bone's region is sacral.

Answer:

a. Sacral
