An anterior cruciate ligament (ACL) tear is a common knee injury among athletes. The function of ligaments is to attach bones to each other and keep them stable. Given what you know about connective tissue, what type of tissue do you expect would be involved?

• A. Loose Connective Tissue Proper. 
• B. Dense Regular Connective Tissue.
• C. Areolar Connective Tissue. 
• D. Dense Irregular Connective Tissue.

Answer: (B)

Verified step by step guidance

1. Understand the role of ligaments: Ligaments are connective tissues that connect bones to each other, providing stability to joints. They need to be strong and able to withstand tension.
2. Identify the types of connective tissue: Connective tissues are categorized into loose and dense types. Loose connective tissues include areolar tissue, which is more flexible and less dense. Dense connective tissues are stronger and more fibrous.
3. Consider the structure of dense connective tissues: Dense connective tissues are further divided into regular and irregular types. Dense regular connective tissue has fibers aligned in parallel, providing strength in one direction, which is ideal for ligaments.
4. Evaluate the function of dense regular connective tissue: This type of tissue is designed to resist tension and provide stability, making it suitable for ligaments that experience stress from various movements.
5. Conclude the type of tissue involved in ACL: Given the need for strength and stability in ligaments, dense regular connective tissue is the most appropriate type involved in the structure of the ACL.
