Firstly, To understand the Psoas Paradox, the Psoas are a muscle that attaches at 2 ends, that being the transverse process of the T12-L5 and inserts to Lesser trochanter of the hip. Upon contraction this muscle (like all muscle groups) contract at both ends, thereby raising the thigh upwards towards an erect trunk and pulls the lumabr spine into a curve (Lordosis).
The paradox of this is that upon passive thigh raising towards the trunk, the lower spine actually rather flattens than becoming more lordotic. This is due to the fact that upon passive flexion of the thigh, the Psoas undergoes compressive strain thereby causing the muscle to be slack about its attatchment (lumbar spine Transverse processes)
The difference between active and passive muscle tension is what causes this "Paradox"

What are the hips also known as?
They are called Labia, which is Latin for "lips.".
What is the primary flexor of the hip?
The primary flexor of the hip is the Illiopsoas. Or more specifically the Psoas Major which originates transverse processes T12 to L5 of the vertebral column and Inserts onto the Lesser Trochanter of the femur.
Where does photosynthesis generally occur?
Photosynthesis occurs usually occurs in the leaves. It occurs where there is most chlorophyll.
Does psoas paradox occur when the hip flexors and spinal extensors contract at the same time?
yes
What is the psoas nerve?
The psoas nerve is the nerve that innervates the psoas major muscle. It is formed by fibers of spinal nerves L2-L4.
