Autochthone Rückenmuskulatur: Medialer Trakt

The video tutorial focuses on the autochthonous back muscles, their development, and classification into medial and lateral tracts. It explains the spinal and transversus spinal systems, detailing specific muscles like interspinalis, spinalis, rotatores, multifidus, and semispinalis. The tutorial covers muscle functions, including dorsal extension and lateral flexion, and concludes with a recap of the medial tract's role in back stabilization and rotation.

What distinguishes the interspinalis muscles from other back muscles?

How do the semi-spinalis muscles function during unilateral contraction?

Summarize the main functions of the medial tract muscles.

What happens during bilateral contraction of the medial tract muscles?
