The neurovascular bundle formed by the artery and the cords of the brachial plexus are enveloped Axillary artery (Arteria axillaris) The axillary artery is a large muscular vessel that travels through the axilla.It is responsible for carrying oxygen-rich blood to the upper limb, as well as to parts of the musculocutaneous system of the scapula and upper lateral thorax.. The space is completed by the teres major inferiorly, teres minor posteriorly and long head of triceps brachii laterally. An equally important artery is the facial artery, which supplies the muscles of facial expression. It also extends laterally as the axillary sheath, surrounding the axillary artery, the axillary vein and brachial plexus (the network of nerves supplying the upper limbs). Along with the levator scapulae, trapezius and rhomboid muscles, the latissimus dorsi belongs to the superficial layer The medial pectoral nerve is solely a motor nerve. Bones and joints. The thoracic, or chest wall, consists of a skeletal framework, fascia, muscles, and neurovasculature all connected together to form a strong and protective yet flexible cage.. The axillary nerve is one of the terminal branches brachial plexus, derived from its posterior cord (C5-6).It travels through the quadrangular space together with the posterior circumflex artery and vein.. The medial pectoral nerve, also called the medial anterior thoracic nerve, is a branch of the medial cord of the brachial plexus pon originating, the nerve travels together with the axillary artery and vein, being located between. Vertebral arteries The vertebral arteries stem from the subclavian arteries; two major arteries of the thorax that lie beneath the clavicles.The vertebral arteries ascend through the neck inside the transverse foramina of the cervical vertebrae, all the way to the brain.Through their course, they give off several meningeal, muscular and spinal branches for the nearby structures. Axillary artery (Arteria axillaris) The axillary artery is a large muscular vessel that travels through the axilla.It is responsible for carrying oxygen-rich blood to the upper limb, as well as to parts of the musculocutaneous system of the scapula and upper lateral thorax.. Bones and joints. It is a mixed nerve, meaning that it has both motor and sensory fibers which innervate important muscles of the upper limb and parts of the skin within the axillary This space allows the passage of the circumflex scapular artery and vein from the axillary region to the scapular region. Pronation and supination are movements that occur at the proximal radioulnar joint.The head of the radius is discoid and fits with the radial neck within the circular annular ligament, that attaches the proximal radius to the ulna.The wheel like rotation of the head of the radius enables supination (palm facing upwards), and pronation (palm facing downwards). Thoracoacromial artery (branch of the second part of axillary artery) gives two supplying branches - pectoral and deltoid. Lateral thoracic artery (branch of the axillary artery). Shaft. The prevertebral layer contains the cervical parts of the sympathetic trunks , the above mentioned muscles, the scalene muscles and deep cervical muscles. Its main function is to provide motor supply for the pectoralis major and pectoralis minor The neurovascular bundle formed by the artery and the cords of the brachial plexus are enveloped The cephalic vein is a superficial vein of the upper limb and it's one of the two main veins of the arm. Pectoralis muscle has several functions, mostly related to the movement of the scapula. Median nerve: Origin and course. It is in close proximity to the axillary nerve and the posterior circumflex humeral artery. The prevertebral layer contains the cervical parts of the sympathetic trunks , the above mentioned muscles, the scalene muscles and deep cervical muscles. The medial pectoral nerve is solely a motor nerve. Due to the The median nerve is a branch of the brachial plexus that supplies most of the superficial and deep flexors in the forearm, thenar and lumbrical muscles.It also gives sensation to certain areas of the skin of the hand.. Due to its innervation field, the median nerve enables us to perform both coarse and fine movements of the upper limb. The contraction of the entire serratus anterior leads to a anterolateral movement of the scapula along the ribs. The upper triangular space is bounded by teres minor and subscapularis superiorly, teres major inferiorly and the long head of triceps laterally. The subclavian artery is a paired arterial vessel of the thorax.The right and left arteries have different origins; the left subclavian artery originates directly from the aortic arch, while the right subclavian artery originates from the brachiocephalic trunk.. This is where the proximal end of the humerus joins with the long shaft. Both profunda brachii and the brachial artery give important branches that form the elbow anastomoses. Pectoralis muscle has several functions, mostly related to the movement of the scapula. The cephalic vein is a superficial vein of the upper limb and it's one of the two main veins of the arm. ; The lower triangular space, also called the triangular interval, is bounded by teres major superiorly, the Thoracic wall The first step in understanding thorax anatomy is to find out its boundaries. It consists of three borders known as the anterior, lateral and medial borders. It is a mixed nerve, meaning that it has both motor and sensory fibers which innervate important muscles of the upper limb and parts of the skin within the axillary Its name derives from cephalic meaning head, as the vein runs up to the shoulder.The superficial venous network is the source of blood for most blood tests, and is the easiest place to access venous blood. The vascular supply to the serratus anterior comes from the superior and lateral thoracic arteries (branches of the axillary artery) as well as branches from the thoracodorsal artery (branch of subscapular artery)..
