In the human body, the bones that make up these structures collectively make up the axis, the central bony core. The skull, vertebral column, ribs, and sternum make up the axial skeleton. Either comprehensive protection or the supply of large surfaces for muscle attachment is the main feature of flat bones.The skeletal system consists of two groups of bones: the axial and appendicular skeletons. Note:The flat bones are the parietal, occipital, frontal, lacrimal, nasal, hip bone, vomer, ribs, sternum and scapulae. Thus, the correct answer is option (D) Ribs. In the back, all 12 of the ribs are attached to the spine. A cagelike protective framework is built around the organs of the upper torso. Each rib is a thin flat bone attached to the vertebral column dorsally and to the sternum ventrally. The incus is a small bone and is one of the middle ear’s three ossicles. Thus, the option B is incorrect.Ī bone in the middle ear is the incus or anvil. The intervertebral disc removes the remaining 9 vertebrae and creates two sets of fused structures. In an adult human being, the vertebral column consists of 33 vertebrae, of which 24 are classified as articulating vertebrae and are divided by an intervertebral disc. The tunnel is bounded by the wrist bones and the connective tissue flexor retinaculum. Now, let us find the solution from the options-Ĭarpel is a tunnel that connects the forearm to the hand. Flat bones function as a point of connection for muscles or protection for the internal organs. They form a protective framework which is cagelike. Hint: It is a flat bone that is attached to the sternum.
