Which muscles with fibers run at an angle to the long axis of body?

The muscles with fibers that run at an angle to the long axis of the body are:

1. External Obliques: These are the outermost abdominal muscles and their fibers run obliquely, from the lower ribs to the pelvis.

2. Internal Obliques: Located deeper to the external obliques, the fibers of the internal obliques also run obliquely, but in the opposite direction to the external obliques.

3. Transversus Abdominis: The deepest abdominal muscle, the transversus abdominis, has its fibers running horizontally across the abdomen.

4. Pectoralis Major: The large chest muscle responsible for chest movement, the pectoralis major has fibers that originate from the sternum, clavicle, and costal cartilages and converge towards the insertion point on the humerus bone.

5. Gluteus Medius: One of the three gluteal muscles in the hip region, the gluteus medius has fibers running diagonally from the ilium bone to the greater trochanter of the femur bone.

6. Gluteus Minimus: The smaller muscle situated beneath the gluteus medius, the gluteus minimus, also has fibers running obliquely from the ilium to the greater trochanter.

These muscles with fibers running at an angle to the long axis of the body play important roles in various movements, such as twisting, bending, and rotating the body. Their angular orientation allows them to generate force in different directions, providing stability and flexibility during physical activities.
