Why is this Muscle Pso Important?
What muscle helps you walk, run, climb stairs, and dance? That’s right, the psoas muscle (pronounced “so-as”). Its name derives from Greek ψόας, psóās, meaning ‘of the loins.’
This article discusses the significant functions of the psoas muscle and how you can keep it healthy. Read on to learn more.
What is the psoas muscle?
Three essential muscles in the human body link the spine to the legs. These are:
- Gluteus maximus
- Piriformis
- Psoas muscles
The psoas muscle is a long spindle-shaped muscle that lies on either side of the lumbar region of the vertebral column. The psoas muscle lies adjacent to the lesser pelvis region. It connects the iliacus muscle to the iliopsoas. In some cases, the psoas major may be assisted by the minor.
The psoas muscle has two major parts: the superficial and deep regions. The deep part of the psoas muscle begins from the transverse process of the lumbar vertebrae. On the other hand, the shallow area starts from the lateral surface of the thoracic vertebrae, the lumbar vertebrae, and intervertebral discs. Finally, the simple part is separated from the deep part by the lumbar plexus.
