What is the origin of splenius capitis?

Explanation:
Splenius capitis arises from the lower portion of the nuchal ligament and from the spinous processes of the cervical and upper thoracic spine. In most texts this is described as from C7 through T4 (some sources extend to T3 or even T6). That combination—C7-T4 (or nearby) with the nuchal ligament—captures the region where the muscle attaches and is why this option is correct. The other options point to origins in regions that aren’t part of splenius capitis’ typical attachment: the mid-to-lower thoracic or lumbar spine, or a more limited cervical range that doesn’t include the upper thoracic or the nuchal ligament.
