Thoracic Ventral Rami Flashcards
The grey ramus communicans joins to the ventral rami of the thoracic spinal nerve (proximal/distal)to the exit of the white ramus communicant.
Proximal
Each of the thoracic ventral rami connects to the adjacent sympathetic ganglion through the (grey,white, or both) rami communicans.
Both
Name the thoracic ventral rami which are distributed to the thoracic wall only.
T3-T6 ventral rami
Name the nerve, which pierce the chest wall in front of the serratus anterior to supply the axillaryskin. __________ of ___________
Lateral cutaneous branch of T1 ventral rami
Name the muscles, where intercostal nerves run between them. Outside: ______, Inside: _____
Outside: internal intercostals
Inside: subcostals and innermost intercostals
Name three structures, which intercostal nerves pierce to become the anterior cutaneous nerve ofthe thorax.
internal intercostal muscle, external intercostal membrane and pectoralis major.
Name the nerve, which supplies the abdominal skin in the upper part of the infrasternal angle.
anterior cutaneous n. T6 ventral ramus
Name six muscles, which are innervated by first to sixth thoracic ventral rami.
Serratus posterior superior, internal intercostals, external intercostals, innermost intercostals, subcostals, transversus thoracis.
Name two nerves, which might supply the upper digitations of the external oblique abdominalmuscle.
5th and 6th Anterior branches of the lateral cutaneous n.
Name the nerves, which supply the skin over the scapular and latissimus dorsi.
Posterior branch of lateral cutaneous nerve
Name the nerve which supplies the skin around the umbilicus.
T10 ventral ramus
Name three nerves, which innervate the serratus posterior inferior.

T12 ventral ramus/subcostal nerve.
Name the nerve, which supplies the pyramidalis.
T12 ventral ramus/subcostal nerve.
Name the nerve, which supplies the anterior gluteal skin up to the greater trochanter.
