The function of the rectus abdominis is spinal flexion.
What spinal curvature will result when you throw your torso into lateral flexion?
A spinal fracture will only cause paralysis if the spinal cord is also damaged. A C5 injury will affect finger flexion and extension, wrist flexion, tricepts, and all muscle groups from the chest downwards throughout the body. Breathing will be compromised, as will bowel, bladder and sexual function.

The recommended range of back flexion degrees for optimal spinal health and flexibility is typically between 20 to 45 degrees. This range helps to maintain a balance between mobility and stability in the spine, reducing the risk of injury and promoting overall spinal health.

Flexion movements of the back involve bending forward, while extension movements involve arching backward. Flexion can help stretch the back muscles and improve flexibility, but excessive flexion can strain the spine. Extension movements help strengthen the back muscles and improve posture, but too much extension can also lead to strain. Balancing both movements is important for overall spinal health and function.
Walking up the stairs involves flexion at the hip and knee joints to lift the leg, as well as plantar flexion at the ankle joint to push off the ground. Additionally, there is extension at the hip and knee joints to move the body up the stairs.
During a sit-up, the primary joint movements that occur are hip flexion as the hips bend, lumbar spine flexion as the back rounds forward, and thoracic spine flexion as the upper body moves towards the knees. The shoulder movement might also involve slight flexion as the arms reach forward towards the knees.
The abdominal muscles do many things like hold and potect the abdominal cavity and assist in breathing. But, the most obvious one is posture. They are the antagonists to the muscles along the spine and help maintain spinal curvature. The action is known as flexion of the spinal column.
It is Flexion and Extension
