Lateral mammary branches. Rami mammarii laterales. A

Subscapular artery. A. subscapularis. Arises at the lateral margin of the subscapularis muscle and supplies it, the latissimus dorsi and teres major muscles. A

Thoracodorsal artery. A. thoracodorsalis. Branch to the latissimus dorsi and teres major. A

Circumflex scapular artery. A. circumflexa scapulae. It passes through the triangular space to the infraspinous fossa and anastomoses with the suprascapular artery. A Anterior circumflex humeral artery. A. cir-cumflexa anterior humeri. It arises below the latissimus dorsi at the same level or deeper than the posterior circumflex humeral artery and passes in front of the surgical neck of the humerus to the coracobrachialis and biceps. It anastomoses with the posterior circumflex humeral artery. A

Posterior circumflex humeral artery. A. cir-cumflexa posterior humeri. It passes with the axillary nerve through the quadrangular space to the shoulder joint and the deltoid muscle. It anastomoses with the anterior circumflex humeral, suprascapularis and thoracoacromial arteries. A

Brachial artery. A. brachialis. It forms a continuation of the axillary artery from the lower margin of the pectoralis major in the medial bicipital groove up to its division into the radial and ulnar arteries. A

Superficial brachial artery. [A. brachialis su-perficialis]. Anatomic variant in which the brachial artery lies on the median nerve instead of below it. A

Profunda brachii artery. A. profunda brachii. Companion artery of the radial nerve in the groove for the radial nerve. A Nutrient arteries of humerus. Aa. nutriciae (nutrientes) humeri. Branches to the bone marrow of the humerus. A Deltoid branch. Ramus deltoideus. Branch coursing laterallybehind the humerus,then superiorly and externally to the deltoid muscle. A Middle collateral artery. A.collateralis media. It arises behind the humerus and descends to the articular network of the elbow. A Radial collateral artery. A. collateralis radialis. It passes with the radial nerve to the articular network of the elbow and gives off an anterior branch to the radial recurrent artery. A Superior ulnar collateral artery. A. collateralis ulnaris superior. Often arising near the profunda brachii artery, it passes with the ulnar nerve to the articular network of the elbow. A Inferior ulnar collateral artery. A. collateralis ulnaris inferior. Originating above the medial epicondyle of the humerus, it passes on the brachialismuscleandthroughtheintermuscular septum to the articular network of the elbow. A

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
