Step-by-step explanation:
The ribs are vital bones of the body, protecting vital organs. If you want to know the number of ribs humans have, and know more about their structure and function, keep reading.
Human rib cage
The ribs protect the vital organs of the body, and hence, are among the most important bones in the human body. They form a cage-like structure around the vital organs, and due to this, all the ribs are collectively called the rib cage. However, there are other bones besides the ribs that make up the rib cage. In the following paragraphs, we tell you more about the functions and importance of the rib cage.
The human skull is the bony structure that forms the head in the human skeleton. It supports the structures of the face and forms a cavity for the brain. Like the skulls of other vertebrates, it protects the brain from injury.[3]
The skull consists of three parts, of different embryological origin—the neurocranium, the sutures, and the facial skeleton (also called the membraneous viscerocranium). The neurocranium (or braincase) forms the protective cranial cavity that surrounds and houses the brain and brainstem.[4] The upper areas of the cranial bones form the calvaria (skullcap). The membranous viscerocranium includes the mandible.
The sutures are fairly rigid joints between bones of the neurocranium.
The facial skeleton is formed by the bones supporting the face.
