Anatomical terms of bone. [edit on Wikidata] In vertebrates, thoracic vertebrae compose the middle segment of the vertebral column, between the cervical vertebrae and the lumbar vertebrae. [1] In humans, there are twelve thoracic vertebrae of intermediate size between the cervical and lumbar vertebrae; they increase in size going towards the ...
The intercostal nerves are part of the somatic nervous system, and arise from the anterior rami of the thoracic spinal nerves from T1 to T11. [1] [2] The intercostal nerves are distributed chiefly to the thoracic pleura and abdominal peritoneum, and differ from the anterior rami of the other spinal nerves in that each pursues an independent course without plexus formation.
Latin. nervi spinalis. FMA. 6312. Anatomical terminology. [edit on Wikidata] The thoracic spinal nerve 11 (T11) is a spinal nerve of the thoracic segment. [1] It originates from the spinal column from below the thoracic vertebra 11 (T11).

The facet joint is the joint between the inferior articular process (labeled at bottom) and the superior articular process (labeled at top) of the subsequent vertebra. The facet joints (also zygapophysial joints, zygapophyseal, apophyseal, or Z-joints) are a set of synovial, plane joints between the articular processes of two adjacent vertebrae.
The thoracic cavity (or chest cavity) is the chamber of the body of vertebrates that is protected by the thoracic wall (rib cage and associated skin, muscle, and fascia). The central compartment of the thoracic cavity is the mediastinum. There are two openings of the thoracic cavity, a superior thoracic aperture known as the thoracic inlet and ...
Withers are the ridge between the shoulder blades of an animal, typically a quadruped. In many species, this ridge is the tallest point of the body. In horses and dogs, it is the standard place to measure the animal's height. In contrast, cattle are often measured to the top of the hips.
The costotransverse joint is the joint formed between the facet of the tubercle of the rib and the adjacent transverse process of a thoracic vertebra. The costotransverse joint is a plane type of synovial joint which, under physiological conditions, allows only gliding movement. [citation needed] This costotransverse joint is present in all but ...
