What do you understand by hub and rib cage
Answers
Answer:
The rib cage is the arrangement of ribs attached to the vertebral column and sternum in the thorax of most vertebrates, that encloses.
Answer:
The ribs are curved, flat bones which form the majority of the thoracic cage. They are extremely light, but highly resilient; contributing to their role in protecting the internal thoracic organs.
There are twelve pairs of ribs, all of which articulate with the vertebral column. However, only seven have a direct articulation with the sternum. As such, ribs can be allocated to one of three distinct types; true (vertebrosternal) ribs, false (vertebrochondral) ribs and floating (vertebral, free) ribs. Ribs one to seven are considered true ribs and attach directly to the sternum via their own costal cartilage.
Ribs eight to ten are the false ribs and are connected to the sternum indirectly via the cartilage of the rib above them. The final two pairs of ribs are floating ribs and the cartilage of these ribs tends to end within the abdominal musculature. These three types can then be classified as either typical or atypical.
A hub is a physical layer networking device which is used to connect multiple devices in a network. They are generally used to connect computers in a LAN. A hub has many ports in it. A computer which intends to be connected to the network is plugged in to one of these ports.
