4. The _________ divides the abs vertically.

Linea alba

Aponeurosis

The linea alba is a fibrous structure that runs vertically in the midline of the abdomen, dividing the abdominal muscles into left and right sides. It is a white, tendinous line that is formed by the fusion of the aponeuroses (flat tendons) of the abdominal muscles. The linea alba provides stability and support to the abdominal wall and helps to maintain the integrity of the midline.

3

The TMJ (temporomandibular joint) is located in the jaw, specifically where the lower jaw bone (mandible) connects to the skull. This joint allows for movement of the jaw, including opening and closing the mouth, chewing, and speaking. Option 3 is the correct answer as it indicates the location of the TMJ.

This joint allows for movement of the jaw, including opening and closing the mouth, chewing, and speaking. Option 3 is the correct answer as it indicates the location of the TMJ.

6. The _________ divides the abs horizontally.

Linea alba

Aponeurosis

The aponeurosis is a broad, flat tendon-like structure that connects muscles to other muscles or to bones. In the context of the question, the aponeurosis divides the abs horizontally. This means that it separates the abdominal muscles into upper and lower sections. The linea alba, on the other hand, is a fibrous band that runs vertically down the midline of the abdomen, not horizontally. Therefore, the correct answer is aponeurosis.

7. What does TMJ stand for?

TMJ stands for Temporal Mandibular Joint. The Temporal Mandibular Joint refers to the joint connecting the temporal bone of the skull and the mandible (lower jaw). This joint allows for the movement of the jaw, such as opening and closing, chewing, and speaking. TMJ is commonly used to refer to disorders or issues related to this joint, which can cause pain, discomfort, and difficulty in jaw movement.
