The ribs are attached at the thoracic region of the spinal column. There are twelve vertebra that make up the thoracic spine. Which can be referred to as T1, the top of the thoracic spine through the bottom of the thoracic spine T12 or T1 - T12. The twelve pair of human ribs are classified as True ribs, False ribs and Floating ribs depending on the ribs pair location on the thoracic spine.
All attach to a vertebra, The upper 6 also attach to the sternum, the bottom 6 just "float".
The sternum, ribs 3-6 (3 on each side) and vertebra T 3-6 for a total of 10.
The two locations on a thoracic vertebra where the ribs articulate are the costal facets on the sides of the vertebral body and the transverse costal facets on the transverse processes. These articulations form the joints that connect the ribs to the thoracic vertebrae.
well, a dog has 13 pair of ribs or 26 ribs overall.
The term "Gorilla rib" is used to describe a Lumbar rib. Most humans only have ribs bilaterally attached to their 12 thoracic vertebra but a number of variations exist with cervical ribs, lumbar ribs and even so called sacral ribs. Approximately 8% of humans have a extra rib attached to their lumbar vertebra which also occurs in some types of gorillas
Both sexes are equal in having 12 pair of ribs.
