There are 206 bones of the human skeleton. Bone is a connective tissue that are considered organs. Bones are composed of collagen and a mineral called hydroxyapatite, it gives the bones its incredible strength. The bones are important structures in the body for several reasons they support, protect, produce hormones, store minerals and growth factors and allows the body to move. Homeostatic imbalance of the bone can result in diseases of the bone such as Osteitis Deformans, which causes a weak growth of development of bones.
Cervical vertebra locates in the neck between occipital bone and T1 vertebra. It helps hold up the skull and protects the spinal cord. Atlas and axis are very special bones because they provide the movements for the head. Atlas is a ring-shaped vertebra that rotates and axis is a pivot that helps the head to turn side to side. Thoracic vertebra has a very important job is to protect the heart and lungs which locates in the trunk between C7 and L1 of the body. Lumbar vertebra is consider as the lower back between T12 and S1 in the body that can helps support the weight of the body. Sacrum and coccyx located in the lower back between L5 and C1. Sacrum is a very tough bone that supports the weight and coccyx, also known as the tail bone, connects with the muscles to the pelvic
The framework of the human body is the skeletal system. Skeletal system organs include the bones, joints, cartilages, ligaments, tendons and teeth. Bones offer support for the muscles, protect our vital organs, and allow us to eat food. Our joints allow our body to move, twist and bend. Cartilage, like our ears and nose, offer soft structures that are more malleable than bones. Two separate bones are connected by ligaments, and bones and muscles are connected by tendons. Our teeth allow us to bite and chew our food. Skeletal structure is similar among all people around the world, with the greatest diversity occurring between the sexes. We will explore each system in greater detail and provide
The Skeletal system is a vital part of the human body due to the appendicular skeleton helping our bodies lift up objects, the axial skeleton helping us stand upright, but also, some bones can break and develop bone diseases, yet there are still many ways to prevent it.
The axial skeleton is compromised by the skull (cranium), hyoid bone, vertebral column, and the thorax (ribs and sternum). The axial skeleton functions to protect and support organs of the head, neck, and trunk. There are 22 facial and cranial bones that interlock to form openings for the eyes and protection of the brain in the skull. Whereas, the vertebral column consists of individual vertebrae separated by cartilaginous disks. The vertebral column forms the middle axis of the skeleton.
The skeletal system provides format for the body. “The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments, and cartilage that connects them” (Zimmerman, 2016). This system shields our inner organs and especially our spinal cord. The brain is enclosed by the cranium to provide protection. Bones organize together so that the muscles attached to our body can have movement. The tendons are links that clutches the muscle and bone together. The skeletal has different types of tissue within the bone. The compact bone is firm and solid. It is the exterior of majority of the bones and the main section of the longer bones. The spongy bone contains red marrow. It can be found on the top of the femur bone and in the middle of other bones.
The adult human skeletal system consists of 206 bones, but the skeletal system is much more than just bones. It also includes the network of tendons, ligaments and cartilage that connects them. Bones aren’t just solid white lumps of calcium, there are various elements that make up a single bone.
The four major components of the axial skeleton include the skull, spine, ribs, and sternum. The structures of the skull provides framework that supports the brain which in turn supports the spinal cord. The spinal cord keeps our upper half of our body sitting upward. The spine is also a connecting piece for all other parts of the skeleton. The ribs protect lungs and other organs underneath from external damage. The ribs are bonded through the spine which holds the skull upright. Finally, the sternum is connected to the rib bone, connected to spine/skull. Its primary function is to serve as a connecting piece for the rib cage that stabilizes the thoratic skeleton. The axial skeleton provides support and structure for adjusting the position
The axial skeleton consists of the skull, vertebral column, ribs and sternum, forming the supporting structure for the rest of the skeleton. The appendicular skeletons the appendages, or limbs, and supporting joints and girdles. The coxal bone, arms and legs are all parts of the appendicular skeleton.
There are two categories that in formation of the complete Articulated Skeleton: axial and appendicular. Axial skeletal is the central part of body that consists of the bones of the head and trunk of a vertebrate. It has 80 bones in total, and it is composed of 6 parts: the skull bones, the bones of inner ear, the hyoid bones, the rig cage, sternum and the vertebral column. The skull forms and supports the head and face structure. Except lower jaw (mandible), all bones of the skull are joined by fixed joints formed by bony ossification. The bones of inner ear are also called ossicles, they are the one of smallest bones in the human body, and they transmit sounds from air to brain. The hyoid bone locates between the chin and the thyroid cartilage and base of the lower
The appendicular skeleton consists of 126 bones containing the appendage bones, the pectoral and pelvic girdles. It is responsible for the ability of movements and the protection of the major organs in the human body.
The musculoskeletal system is a made up of the muscular system and the skeletal system. The skeletal system provides the internal framework for the body, it protects the organs by enclosing it and anchors skeletal muscles so that the muscles can contract thus causing movement. The skeleton is divided into two divisions: the axial skeleton and the appendicular skeleton (Taylor & Cohen, 2013, p. 94). The Axial skeleton are the bones that have formed the longitudinal axis of the body which is made up of the skull, the vertebral column and the thoracic cage (Taylor & Cohen, 2013, p. 98). The Appendicular skeleton are the bones of limbs and griddles that are attached to the axial skeleton (Taylor & Cohen, 2013, p. 103).
Have you ever thought about how humans would be without bones? They would not be able to function the way that they do now if it did not have bones. The skeletal system is a highly important system in the human body, it functions as support, protection, and creation of red blood cells. This system is composed of bones and joints, an average adult contains 206 bone and an average child contains 270 bones because as a person grows the bones fuse together to create a single bone. The skeletal system is divided in to two major category: the axial skeleton and the appendicular skeleton. The axial skeleton has 80 bones in the midline axis which contains the bones of the head and the trunk; while the appendicular axis has 126 bones which include the bones from the limbs, pectoral and pelvic regions. There are only a few select bones that are mainly affected by the Paget disease these include the pelvis and the tibia which belong to the appendicular axis; however, other bones that could be affected are the femur, spine, skull, clavicle, and fibula.
