Which of these muscles is not responsible for flexion or extension of the arm?
The humerus-ulna joint at the elbow is a hinge joint. This type of joint allows for flexion and extension movements, enabling the forearm to bend and straighten relative to the upper arm. The structure of the joint provides stability and allows for a wide range of motion in these two primary directions.

the cardiac muscle
The psoas major is a skeletal muscle tissue. It is a long, thick muscle located in the lower back and is part of the iliopsoas group, which helps in hip flexion and stabilizing the spine. The muscle is essential for various movements, including walking, running, and standing up from a seated position. It is innervated by the lumbar plexus and plays a crucial role in posture and core stability.
