Which of the following is NOT found in the RADICULAR (root) pulp?
Show answer and explanation
Correct answer: B. Pulp horns
Pulp horns are extensions of the CORONAL pulp toward the cusps — they are NOT found in the radicular pulp.
- A. The apical foramen is the primary exit of the radicular pulp at the root apex — it is definitively part of the radicular pulp.
- B. CORRECT. Pulp horns are projections of the coronal pulp extending toward the cusp tips. They are part of the CORONAL pulp, not the radicular pulp.
- C. Lateral canals are found along the radicular portion of the pulp and communicate with the periodontium.
- D. Canal orifices are the transition points at the floor of the pulp chamber into the root canals — relevant to radicular pulp access.
