One of the major functions of the skeletal system includes protection. This also helps in maintaining the overall shape of the human body. The whole skeletal system is based on a solid framework which safeguards the human body and its organs from the external environment. It provides the needed support to all the organs and the muscles whic h help them in moving efficiently. Some of the major functions of the skeletal system are described below: We would have been a lump of mass and muscle if there were no bones in the body. The human body would not have functioned as it does without the skeletal system. The movements of the human body would not be visible if the bones lacked joints. The skeletal system's joints are crucial because they enable a variety of movements to occur at various points. All of these parts are rigid and tough in nature and have a function of movement. All the bones and tissues along with the cartilages and the joints from the whole skeletal system. The skeletal system forms the basic framework of the body around which the whole body is built and structured. All the bones except the mandible are joined together. The human body has a movable jaw because of the mandible bone. The mandible forms the lower jaw and is responsible for holding the lower teeth in place. It is also considered one of the strongest and the largest bones in the facial skeleton. The jaw bone name mandible is the only movable skull bone that is present in our facial skeletal bones. Although, if the auditory ossicles (bones in the ears) are also included, then the number of bones in the skull reaches up to 28. This makes the total number of skull bones to be 22 in number. In addition, the skull supports all the facial structures. The neurocranium almost completely encloses the brain, with the exception of the foramen magnum and other foramina at the base of the skull that serves as an entry and exit point for blood vessels and cranial nerves. Its primary function is to protect the brain, the most important organ in the human body. The braincase (neurocranium) and facial skeleton are separated by the skull (viscerocranium). The human skull is made up of 22 bones which are mostly joined together by ossified joints known as sutures. The article below gives us an insight into the mandible and other skull bones along with their structure and formation. Out of the 28 bones, the number of movable bones in the skull is only one bone called the mandible or the jaw bone of the facial bones. These bones include our cranial and facial skeletal bones forming the skull. The cartilage and ligaments keep the skull together. The skull features numerous foramina through which pass the cranial nerves, the spinal cord, arteries, and veins.The skull is made up of 22 bones along with 6 auditory ossicles which makes the total number of bones in the skull to be 28. The temporomandibular joint connects the lower jaw to the temporal bone and enables movement for speech and mastication. The viscerocranium consists of the unpaired mandible and vomer and the paired zygomatic bones, inferior nasal conchae, lacrimal bones, nasal bones, maxillary bones, and palatine bones. The fontanelles, which comprise the anterior, posterior, and the paired mastoid and sphenoid fontanelles, close between the age of 2 months and 18 months. The bones of the infant neurocranium are not fused but are instead connected by membranous gaps between the bone plates called fontanelles, which enable flexion of the skull to facilitate passage through the birth canal and accommodate the rapidly growing brain. The cranial bones are connected by fibrous joints called sutures. The neurocranium consists of the frontal, the ethmoid, the sphenoid, the occipital, and the paired temporal and parietal bones. The human skull consists of approximately 30 bones, which can be anatomically divided into the cranial bones ( neurocranium) and the facial bones ( viscerocranium).
