The band of tough connective tissue at the midline of the abdomen is the Blank______.Multiple choice question.rectus abdominuslinea albalinea aspera

Step 1: Break Down the Problem

The question requires identifying the correct term that describes the band of tough connective tissue located at the midline of the abdomen.

Step 2: Relevant Concepts

In human anatomy, there are specific terms used to describe structures and features. The key terms from the multiple-choice options are:

1. Rectus Abdominus: This is a muscle in the abdomen that contributes to the anterior wall.
2. Linea Alba: This term refers to the fibrous band that runs down the midline of the abdomen, formed by the fusion of the aponeuroses of the abdominal muscles.
3. Linea Aspera: This term refers to a ridge found on the femur, not applicable in this context.

Step 3: Analysis and Detail

• The rectus abdominus is a muscle, not a connective tissue band.
• The linea alba specifically describes the white fibrous connective tissue that runs vertically along the midline of the abdomen, connecting the two sides of the rectus abdominus muscles.
• The linea aspera is irrelevant to this anatomy question.

Step 4: Verify and Summarize

From the analysis, it's clear that the correct term is "linea alba" as it accurately describes the tough connective tissue band at the midline of the abdomen.

Final Answer

The correct answer is linea alba.
