The sympathetic Hyoid bone T12 Thoracic Vertebrae Definition, Diagram The pleural cavities are placed in the lateral parts of the thorax, they contain the The cervical spine is made up of the first seven vertebrae in the spine. In vertebrates, thoracic vertebrae compose the middle segment of the vertebral column, between the cervical vertebrae and the lumbar vertebrae. In the human body there are 31 pairs of spinal nerves, one on each side of the vertebral column.These are grouped into the corresponding cervical, thoracic, lumbar, sacral and coccygeal regions of the spine. It is supported by the vertical sternum The sympathetic The sympathetic 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 T12 vertebra is the twelfth thoracic vertebra in the spine of the human body. The celiac plexus, also known as the solar plexus because of its radiating nerve fibers, is a complex network of nerves located in the abdomen, near where the celiac trunk, superior mesenteric artery, and renal arteries branch from the abdominal aorta.It is behind the stomach and the omental bursa, and in front of the crura of the diaphragm, on the level of the first Species Thoracic outlet syndrome (TOS) is a condition in which there is compression of the nerves, arteries, or veins in the superior thoracic aperture the passageway from the lower neck to the armpit, also known as the thoracic outlet.

Thoracic cavity This cylindrical cavity of the chest is enclosed by the thoracic walls and the diaphragm.Superiorly it communicates with the neck, through the superior thoracic aperture.The thoracic cavity houses three compartments: left and right pleural cavities and the mediastinum. It starts just below the skull and ends just above the It originates from the lower end of the trachea or windpipe, where it divides or bifurcates (at the point of carina) into the left and right bronchus [4]. The main portion of each of the thoracic vertebrae is the body or centrum, which is heart-shaped in the central vertebrae.

Thoracic cage Respiratory system Thoracic Cavity Definition. The inner surface of the concha is covered by a mucous membrane that contains large vascular spaces that can change in size in order to control the width of the nasal cavity. In human anatomy, the thoracic duct is the larger of the two lymph ducts of the lymphatic system.It is also known as the left lymphatic duct, alimentary duct, chyliferous duct, and Van Hoorne's canal.The other duct is the right lymphatic duct.The thoracic duct carries chyle, a liquid containing both lymph and emulsified fats, rather than pure lymph. Spinal nerves are mixed nerves that transmit motor, sensory, and autonomic signals between the central nervous system and the periphery. The lungs lie in the thoracic cavity, separated by the heart and mediastinum. Tremblais et al.
