Verified step by step guidance

Understand the function of the vertebral column: The vertebral column is responsible for supporting the body's weight, protecting the spinal cord, and allowing movement such as bending, twisting, and stabilizing posture.

Review the role of muscle groups: Muscles that stabilize and move the vertebral column are typically located along the spine and are involved in extension, lateral flexion, and rotation of the back.

Analyze the options: The biceps brachii is a muscle of the upper arm responsible for flexing the elbow. The pectoralis major is a chest muscle involved in arm movement. The quadriceps femoris is a group of muscles in the thigh responsible for knee extension. None of these are directly involved in vertebral column movement or stabilization.

Identify the erector spinae: The erector spinae is a group of muscles and tendons that run along the spine. It is primarily responsible for extending the vertebral column, maintaining posture, and stabilizing the spine during movement.

Conclude that the erector spinae is the correct answer: Based on its anatomical location and function, the erector spinae is the muscle group primarily responsible for movement and stabilization of the vertebral column.
