Here we will describe the two main groups of nerves which supplied the muscles and bony structures of this region – the thoracic spinal nerves and their branches and the thoracic branches of the brachial plexus. To finish off, we'll take a look at some clinical notes relevant to the innervation of the thoracic wall to help consolidate our ...

30 paź 2023 · The typical intercostal nerves are mixed nerves carrying both motor and sensory innervation for the thoracic and abdominal walls. Along their course, the nerves usually give off several branches: The muscular branches for the intercostal muscles, subcostal muscles, serratus posterior superior, levatores costarum and transversus thoracis muscles.
24 lip 2023 · The thoracodorsal nerve arises from the hypaxial motor column of the neural tube. Although the deep back muscles arise from epaxial myotomes and hypaxial myotomes are associated with limb muscles and the ventral body wall, the latissimus dorsi muscle is hypaxial in origin.
Thoracic nerves refer to the 12 pairs of nerves that originate from the dorsal and ventral roots of the corresponding thoracic segments. These nerves distribute sensory and motor fibers to various structures in the thoracic and abdominal wall, including muscles, blood vessels, pleura, and breast tissue.
30 paź 2023 · Bordered by the rib, above and below, the deep fascia of the thorax, superficially, and the endothoracic fascia and pleura, internally, the intercostal space contains essential respiratory muscles, the nervous and vascular supply to the thoracic wall, and contributes to the integrity of the thoracic cage.
The nerves of the thoracic wall include the intercostal nerves, which run between the ribs and supply the muscles and skin of the chest wall. 12 pairs of thoracic spinal nerves divide into posterior rami as well as anterior rami, which continue as the intercostal nerves.
22 maj 2023 · Nerves. The intercostal nerves are commonly grouped into two categories: typical intercostal nerves and atypical intercostal nerves. The typical intercostal nerves (IC) include IC3 through IC6, and the atypical intercostal nerves include IC1 through IC2 and IC8 through IC11.
