A delta fibers course _____ through the pulp.

Apically
Laterally
Coronally
Basally

The correct answer is: Coronally

Delta fibers are a type of nerve fibers found in the pulp of the tooth. These fibers are responsible for transmitting sharp, localized pain. When considering the direction in which these fibers course through the pulp, it is important to understand the anatomy of the tooth. Delta fibers generally course coronally through the pulp, meaning they run towards the crown of the tooth. This arrangement allows for the efficient transmission of pain signals from the tooth to the brain. Therefore, the correct answer is C. In contrast: - Option A, apically, refers to towards the apex or root of the tooth, which is not the typical direction for delta fibers to course through the pulp. - Option B, laterally, refers to the sides of the tooth, which is not the primary direction of delta fibers in the pulp. - Option D, basally, refers to towards the base or bottom of the tooth, which is not the usual course for delta fibers within the pulp.
