The medial pectoral nerve usually arises from the medial cord of the brachial plexus; it can however occasionally arise directly from the anterior division of the inferior trunk of the brachial plexus. [1] [2] It is derived from the eighth cervical (C8) and first thoracic (T1) spinal nerve roots. [1] The origin is situated posterior to the ...
The lateral pectoral nerve (also known as the lateral anterior thoracic nerve) arises from the lateral cord of the brachial plexus, [1] [2] and through it from the C5-7. [1] [2] It passes across the axillary artery and vein, [3] pierces the clavipectoral (coracoclavicular) fascia, and enters the deep surface of the pectoralis major to innervate ...
Its name comes from it being medial to the axillary artery as it passes through the axilla. The other cords of the brachial plexus are the posterior cord and lateral cord. The medial cord gives rise to the following nerves from proximal to distal: medial pectoral nerve (C8-T1) medial brachial cutaneous nerve (T1) medial antebrachial cutaneous ...
The pectoralis major receives dual motor innervation by the medial pectoral nerve and the lateral pectoral nerve, also known as the lateral anterior thoracic nerve. The sternal head receives innervation from the C7, C8 and T1 nerve roots, via the lower trunk of the brachial plexus and the medial pectoral nerve. The clavicular head receives ...
Its name comes from it being lateral to the axillary artery as it passes through the axilla. The other cords of the brachial plexus are the posterior cord and medial cord. The lateral cord gives rise to the following nerves from proximal to distal: lateral pectoral nerve (C5-C7) musculocutaneous nerve (C5-C7)
The cervical spinal nerve 8 (C8) is a spinal nerve of the cervical segment. [1] ... Pectoralis major - Medial and lateral pectoral nerves (C5, C6, C7, C8, T1)
It is formed by joining of the ventral rami of the fifth (C5) and sixth (C6) cervical nerves. The upper trunk divides into an anterior and posterior division. The branches of the upper trunk from proximal to distal are: subclavian nerve (C5-C6) suprascapular nerve (C5-C6) anterior division of upper trunk (C5-C6, forms part of lateral cord)
