Answer and Explanation:

The entire length of longissimus muscle extends from the mastoid process of the temporal bone to the sacrum. The sacrum consists of 4 or 5 vertebrae that are fused for strength to transmit weight of a stationary animal to the rest of the body. Sacrus has a large base and short neutral spine for attachment of back muscles.
