Los músculos intertransversos son un grupo de músculos profundos de la espalda. Inserciones: tienen su origen en las apófisis transversas de las vértebras cervicales y lumbares y se insertan en las apófisis transversas de las vértebras adyacentes. Acciones: Unilaterales: contribuyen a la flexión lateral de la columna vertebral. Bilaterales: estabilizan la columna vertebral. Inervación: ramos anteriores de los nervios raquídeos. Irrigación sanguínea: las regiones cervicales reciben la irrigación sanguínea de las arterias occipital, cervical profunda y vertebral. Las regiones lumbares reciben la irrigación sanguínea a través de las ramas dorsales de las arterias lumbares.

Learn More Frequent questions What are the intertransversi muscles? The intertransversi muscles are a group of deep back muscles that originate from the transverse processes of cervical and lumbar vertebrae and insert into the adjacent transverse processes. They play a crucial role in stabilising the spine and aiding in lateral flexion. What is the primary function of the intertransversi muscles? The intertransversi muscles primarily contribute to lateral flexion of the vertebral column when acting unilaterally, while they stabilise the spine when activated bilaterally. This dual action is essential for maintaining proper posture and spinal alignment. How are the intertransversi muscles innervated? The intertransversi muscles receive their innervation from the anterior rami of the spinal nerves. This innervation is vital for their motor function and coordination during movement. What is the blood supply to the intertransversi muscles? The blood supply to the intertransversi muscles in the cervical region comes from the occipital, deep cervical, and vertebral arteries. In the lumbar region, they are supplied by the dorsal branches of the lumbar arteries, ensuring adequate oxygenation for muscle function. What clinical significance do the intertransversi muscles have? The intertransversi muscles are important for spinal stability and movement; dysfunction or injury to these muscles can lead to back pain and impaired mobility. Understanding their role is crucial for diagnosing and treating spinal conditions. Rate This Article
