Bone still cartilaginous. The following steps are followed in the conversion of cartilage to bone: Bones have a variety of functions: Bones serve a variety of mechanical functions. Together the bones in the body form the skeleton. They provide a frame to keep the body supported, and an attachment point for skeletal muscles, tendons, ligaments and joints, which function together to generate and transfer forces so that individual body parts or the whole body can be manipulated in three-dimensional space (the interaction between bone and muscle is studied in biomechanics). Bones protect internal organs, such as the skull protecting the brain
Mylohyoid muscle Mylohyoid muscle The mylohyoid muscle is a paired muscle running from the mandible to the hyoid bone, forming the floor of the oral cavity of the mouth. It is named after its two attachments near the molar teeth (""mylo"" comes from the Greek word for "molar"). These muscles are mesodermal in embryologic origin. The mylohyoid muscle is derived from the first pharyngeal arch. The mylohyoid muscle is flat and triangular, and is situated immediately superior to the anterior belly of the digastric muscle. It is a pharyngeal muscle (derived from the first pharyngeal arch) and classified as one of the
