Which muscles are known as the 'core' muscles?

The core muscles are primarily responsible for stabilizing the spine and pelvis while providing support for the entire body during movement. The rectus abdominis, transverse abdominis, and obliques are essential components of the core muscles.

The rectus abdominis is commonly recognized as the "six-pack" muscle and plays a significant role in flexing the spine and stabilizing the pelvis. The transverse abdominis acts like a corset around the abdomen, providing a firm foundation for the spine and assisting in maintaining posture. The obliques, which are divided into external and internal types, contribute to the rotation and side bending of the torso, enhancing overall stability and mobility.

Understanding the core's function and anatomy is crucial for effective training and rehabilitation, as a strong core is essential for athletic performance and injury prevention. This explains why the option listing these specific muscles is identified as the correct one.
