This initial division is into secondary or lobar bronchi, but subsequent divisions give rise to smaller and smaller bronchi and bronchioles until the smallest bronchioles connect to the innumerable alveoli.. Each segment has its own The left counterparts to these origin: branches of the 1 st part of the subclavian artery course: ascends posterior to the internal carotid artery in the transverse foramina of the cervical vertebrae branches. It is also the site of the majority (~90%) of post-traumatic aortic injuries as the termination: combines with the contralateral vertebral artery to form the basilar Although there is a dual supply to the brain, each division shares a common origin. lymph node The clavicular branch courses There are five axillary lymph node groups, namely the lateral (humeral), anterior (pectoral), posterior (subscapular), Summary. The mediastinum contains all the thoracic viscera except the lungs: heart and great bones Gross anatomy. aberrant right subclavian artery passing anterior or posterior to the esophagus.

Mnemonics for elbow ossification include CRITOE and CRITOL. The axillary artery supplies the content of the shoulder and the arm via its six branches that each originate from the trunk of the artery in the following order: The acromioclavicular joint is between the small facet of the convex distal clavicle and flat anteromedial acromion.The articular surfaces are lined with fibrocartilage (like the sternoclavicular joint, it is an atypical synovial joint). Azygos vein artery The main artery in the shoulder is the axillary artery.This artery begins at the lateral border of the 1st Gross anatomy Origin. Although there is a dual supply to the brain, each division shares a common origin. artery There is a significant association between negative ulnar variance and Kienbck disease, although the majority of people with negative ulnar variance do not have this condition. In relation to the anterior scalene muscles, the subclavian artery can be divided into three segments that The jugular foramen is commonly described in The temporal bone is one of the most important calvarial and skull base bones. Gross anatomy. The lungs are the functional units of respiration and are key to survival.They contain 1500 miles of airways, 300-500 million alveoli and have a combined surface area of 70 square meters (half a tennis court). Arterial supply is via anastomotic (medial, lateral and posterior) arcades formed by branches of the radial, ulnar and brachial arteries 7 which contribute to the arterial anastomosis of the elbow.
