ribs are called ribcage because our ribs form like a cage to protect our heart, lungs and other internal parts of the body.
Thoracic cage i think
Ribs, just like with any other animal. But if you're talking about the ribcage as a whole from the outside, that would be the barrel.
Human ribs are simply called ribs. They are long curved bones that form the ribcage and provide protection to the organs in the chest cavity.
Intercostal spaces
ribcage
24 ribs (12 on each side).
Because they do not articulate directly onto the vertebrae.
The ribs, sternum and thoracic vertebrae make up the ribcage.
Floating ribs are the last two pairs of ribs in the ribcage, with one on each side. They are called "floating" because they do not attach to the sternum (breastbone) like the other ribs. Instead, they are attached only to the vertebrae in the back.
Tightness around the ribcage can be caused by broken ribs, pulled or strained muscles, or fluid in or around the lung or heart.
The 11th and 12th pairs of ribs are called floating ribs because they are not attached to the sternum or connected to other ribs through cartilage. Instead, they only attach to the vertebrae in the back, leaving them free at the front. This lack of anterior attachment gives them a "floating" appearance, allowing for greater flexibility and movement in the lower ribcage.
The lungs and heart are protected and surrounded by the ribs called the rib cage.
