The fourth thoracic vertebra, together with the fifth, is at the same level as the sternal angle. The thoracic spinal nerve 4 (T4) passes inferior it. A thoracic spine X-ray of a 57-year-old male. Surface orientation of T3 and T7, at middle of spine of scapula and at inferior angle of the scapula, respectively.
The carina occurs at the lower end of the trachea - usually at the level of the 4th to 5th thoracic vertebra. [3] [4] This is in line with the sternal angle, but the carina may raise or descend up to two vertebrae higher or lower with breathing. The carina lies to the left of the midline, and runs antero-posteriorly (front to back). [citation ...
The smallest known adult dog was a Yorkshire Terrier that stood only 6.3 cm (2.5 in) at the shoulder, 9.5 cm (3.7 in) in length along the head and body, and weighed only 113 grams (4.0 oz). The heaviest dog was an English Mastiff named Zorba, which weighed 314 pounds (142 kg). [2]
Cervical vertebrae (Atlas (anatomy) = C1, Axis (anatomy) = C2) Thoracic vertebrae; Lumbar vertebrae; Sacral vertebrae; Coccygeal vertebrae (These are in order superior to inferior- or starting from the top of the spine to the bottom.)

The sacrum in the horse is made up of five fused vertebrae. [14] In birds, the sacral vertebrae are fused with the lumbar and some caudal and thoracic vertebrae to form a single structure called the synsacrum. In the frog, the ilium is elongated and forms a mobile joint with the sacrum that acts as an additional limb to give more power to its ...
It marks the approximate [6] level of the 2nd pair of costal cartilages, [6] [2]: 319 (sources differ) the level of the intervertebral disc between thoracic vertebra T4-T5 [6] [2]: 319 or the lower border of the thoracic vertebra T4, [7]: 218 and the space between the spinous processes of thoracic vertebrae T3-T4.
The rib cage or thoracic cage is an endoskeletal enclosure in the thorax of most vertebrates that comprises the ribs, vertebral column and sternum, which protect the vital organs of the thoracic cavity, such as the heart, lungs and great vessels and support the shoulder girdle to form the core part of the axial skeleton.
The number of vertebrae in a region can vary but overall the number remains the same. In a human vertebral column, there are normally 33 vertebrae. [3] The upper 24 pre-sacral vertebrae are articulating and separated from each other by intervertebral discs, and the lower nine are fused in adults, five in the sacrum and four in the coccyx, or tailbone.
