Which stabilization core muscle is Psoas major?

• A. External obliques
• B. Transverse abdominis
• C. Psoas major
• D. Diaphragm

Answer: (C)

Psoas major helps stabilize the spine by spanning from the lumbar vertebrae to the hip, tying the trunk and pelvis together as the hip moves. This connection allows it to support and maintain neutral alignment of the lumbar spine during dynamic tasks, making it a key stabilizing muscle in the core. External obliques mainly rotate and bend the trunk, not primarily about stabilizing the spine in the same way. Transverse abdominis is another deep stabilizer, but the question highlights the psoas major specifically. The diaphragm is a breathing muscle that can contribute to stabilization via pressure changes, but it isn’t the psoas major. So the psoas major is the stabilization core muscle in this context.
