Anterior ramus of spinal nerve

Anterior Ramus of Spinal Nerve

The Anterior Ramus of Spinal Nerve (also known as the ventral ramus) is a branch of a spinal nerve that supplies muscles and skin on the front of the body. It is one of the two main branches of the spinal nerve, the other being the posterior ramus.

Anatomy

Each spinal nerve divides into an anterior and a posterior ramus. The anterior ramus is larger than the posterior ramus. It carries both motor and sensory fibers. The anterior rami of the spinal nerves, except for the thoracic region, form complex networks of nerves known as plexuses.

Function

The anterior rami of the spinal nerves are responsible for carrying motor and sensory information to and from the front part of the body. This includes the chest, abdomen, and the limbs. They innervate the lateral and anterior parts of the trunk and the upper and lower limbs.

Clinical Significance

Damage to the anterior ramus of a spinal nerve can result in loss of motor function, sensory function, or both, depending on the location and severity of the damage. This can occur as a result of trauma, disease, or surgical complications.
