Breakdown the Problem

1. Identify the key components referred to as "tunics" in arterial walls.
2. Distinguish between the correct and incorrect terms related to arterial wall layers.

Relevant Concepts

• Arterial walls are composed of three main tunics:
  1. Tunica intima (or interna)
  2. Tunica media
  3. Tunica externa (or adventitia)

Analysis and Detail

1. Tunica Connectiva: This term is not standard. While connective tissue exists in the arterial walls, it is not referred to as a separate tunic.
2. Tunica Muscularis: This term is often used interchangeably with tunica media, which contains smooth muscle fibers.
3. Tunica Media: This is the correct term for the middle layer of the arterial wall which is primarily responsible for regulating blood pressure and flow.
4. Tunica Externa: This is the outer layer that provides structural support and protection to the artery.
5. Tunica Interna (or Intima): This is the innermost layer that is in direct contact with the blood flowing through the artery.

Verify and Summarize

To summarize, the valid tunics of arterial walls include:

• Tunica Media
• Tunica Externa
• Tunica Interna

Final Answer

Select the following: tunica muscularis, tunica media, tunica externa, tunica interna.
