Postural muscles, also known as antigravity or tonic muscles, are a group of muscles responsible for maintaining and controlling posture and stability of the body. These muscles work continuously to provide support and hold the body in an upright position against the force of gravity. They are primarily located in the back, neck, and core regions of the body.
Some examples of postural muscles include:
1. Erector spinae: These muscles run along the spine and help maintain the natural curvature of the vertebral column.
2. Multifidus: Located near the spine, these small muscles provide stability and control during movements.
3. Transversospinalis muscles: Including the semispinalis, rotatores, and multifidus, these muscles work together to stabilize and rotate the spine.
4. Deep neck flexors: These muscles are located deep in the neck and help maintain proper head positioning and stability.
5. Quadratus lumborum: Situated in the lower back, these muscles help control lateral flexion and stabilize the pelvis.
6. Pelvic floor muscles: These muscles support the pelvic organs and help maintain posture and stability in the pelvic region.
7. Rectus abdominis: Commonly known as the "abs," this muscle group plays a role in stabilizing the trunk and maintaining posture.
While these are a few examples, there are many other muscles involved in maintaining posture and stability throughout the body.
