The Inverted Chest ? A Wineglass
Ashley Davidoff TheCommonVein.net . 22071b01.800

The apex, also called the cupola is dome shaped, fitting snuggly into the space created by the soft tissue confluence of the mediastinal parietal pleura with the costal parietal pleura and the bony frame formed by the clavicle and first rib.  It is positioned 2-3cm superior to the medial third of the clavicle where it projects through the superior thoracic inlet.

Cupola – shape of the apex
This cupola or dome was photographed in the church of the Villa Melzi gardens in Bellagio, Italy.  If you imagine yourself in the chest cavity and you look up towards the neck, this is what you will see ? the dome shaped structure of the apex of the lung and pleura.

We are Going and You are Coming

The top row of images from left to right reflect, A-P examination of the immature lumbar spine of very young patient, juxtaposed with the lateral examination of a normal thoracic of a normal young adult and lastly the lateral examination of a severely kyphotic elderly patient. The photograph was taken in Italy showing ages ranging from the youngest child in a stroller perhaps 2 years in age, her brother of about 5 or 6, their mother in her late twenties or early thirties and an elderly couple both suffering from the wraths of aging bones ? osteoporosis and severe kyphosis.
