There are 23 bones in the skull. Including the bones of the middle ear and the hyoid bone, the head contains 29 bones. Cranial bones (8) Occipital bone. Parietal bones (2) Frontal bone. Temporal bones (2) Sphenoid bone (sometimes counted as facial) Ethmoid bone (sometimes counted as facial)
Shaped roughly like a necktie, it is one of the largest and longest flat bones of the body. Its three regions are the manubrium, the body, and the xiphoid process.[1] The word sternumoriginates from Ancient Greek στέρνον (stérnon) 'chest'. Structure. [edit] The sternum is a narrow, flat bone, forming the middle portion of the front of ...
Sesamoid bones can be found on joints throughout the human body, including: In the knee—the patella (within the quadriceps tendon). This is the largest sesamoid bone. [4] In the hand—two sesamoid bones are commonly found in the distal portions of the first metacarpal bone (within the tendons of adductor pollicis and flexor pollicis brevis).
The femur is the largest long bone of the body and it is also the strongest bone of the body, as it sees the most compressive force on a day to day basis. If you are eating marrow from a cow, it ...
In many four-legged animalsthe femur is the upper bone of the hindleg. The top of the femurfits into a socket in the pelvis called the hip joint, and the bottom of the femur connects to the shinbone (tibia) and kneecap (patella) to form the knee. In humans the femur is the largest and thickest bone in the body. Structure.

The long bones of the human leg comprise nearly half of adult height. The other primary skeletal component of height are the vertebrae and skull . The outside of the bone consists of a layer of connective tissue called the periosteum. Additionally, the outer shell of the long bone is compact bone, then a deeper layer of cancellous bone (spongy ...
The vertebral column, also known as the spinal column, spine or backbone, is the core part of the axial skeleton in vertebrate animals.The vertebral column is the defining and eponymous characteristic of the vertebrate endoskeleton, where the notochord (an elastic collagen-wrapped glycoprotein rod) found in all chordates has been replaced by a segmented series of mineralized irregular bones ...
