The skeletal system is made up of bones, tendons, cartilages, and ligaments. The bone is a tissue that makes up about eighteen percent of the human body weight (Tortora and Derrickson 183). An infant is born with about 300 to 350 bones but as they grow up some of these bones fuse together. An adult has 206 bones (Zimmermann 2012). The skeletal system has various functions such as support, movement, mineral homeostasis, blood cell production, triglyceride storage, and protection (Tortora and Derrickson 183). The bone continues to grow, remodel and repair itself (Tortora and Derrickson 182). There are some differences between the male and female skeletal system and this difference is mainly due to the role of childbirth (Zimmermann 2012). The skeletal system can be divided into two major groups. These groups are the axial skeleton and appendicular skeleton.
The inside of a bones is made up of three parts; the periosteum, the compact bone, and the spongy bone. The periosteum is a tough connective tissue that covers the hard or compact bone. The compact bone has some spaces and is the strongest form of bone. The spongy bone does not contain osteons (Tortora and Derrickson 186). Some of the damages that can affect the human skeletal system are fractures and arthritis.
The frontal bone is a part of the cranial bones and is located at the forehead. The function of the frontal bone is to protect the front part of the brain. It also helps in identifying a person because it plays a role in the shape of the head and face. The occipital bone is located at the back base of the cranium and it enables movement of the head in relation to the spine. Another type of bone is the sternum. It is located in the center of the chest and it serves as ...

    In this paper I will clarify the relation between the integumentary system and the skeletal system. During this paper I will address how the two systems work together to maintain homeostasis and what occurs when balance is not maintained between the integumentary and skeletal system. During this paper I will explain how osteoporosis is directly linked between both the integumentary and skeletal system and ways to prevent or yield this disease.

    The musculoskeletal system is made up of bones, muscles, cartilage, tendons, ligaments, joints and other connective tissue that supports and binds tissue and other organs together. Each muscle is a discreet organ constructed of skeletal muscle tissue, blood vessels, and nerves. Did you know there are roughly 600 organs that make up the muscular system? They include the cardiac muscles, smooth muscles, and skeletal muscles to name a few. The heart is the cardiac muscle. Smooth muscle are the tissues that line blood vessels and organs, such as the stomach and intestines. The skeletal muscles, which are the most well known and familiar of the muscle organ system, helps hold the skeletal frame work together. They make up bout 40 percent of the

    The skeletal system helps with endocrine regulation, protection, support, movement, calcium storage, and blood cell production. The skeletal system consists of 206 bones, in the adult human body, all of which are divided into two major divisions. One division, the axial skeleton made up from 80 bones, runs along the body’s midline and the other division, the appendicular skeleton which has 126 bones.

  • Skeletal System Of The Human Body

    The human body is made up of 12 different systems. Each system has a separate function while some do work together. One system is called skeletal system which is to serve as a support the body, mineral storage, energy storage (fat), blood cell production, movement (leverage), and protect the internal organs. (Martini, 112). With the help of the muscular system, it keeps us moving and makes us to do tasks that we don’t think about like swinging the arms while running. The average adult skeleton has 206 bones that are joined together by ligaments (bone to bone) and tendons (muscles to bone) to make a protective framework for the tissues and muscles. The vital organs are also protected by the skeleton, brain is covered with skull just like heart

  • Three Functions Of The Skeletal System

    The three functions of the skeletal system are to support, to allow movement, and to protect. The skeleton is the framework of the body and also cradles its soft organs, with it the body would be just a jelly mass it wouldn’t have no definite shape and would just collapse. It supports the softer tissues and provides points of attachment for more skeletal muscles to hold all of the parts of the body upright. For example, the bones of the legs as pillars to support the body trunk we stand up. It also supports the body against the pull of gravity. The skeletal allows movement. The skeletal muscle attached to the bones by tendons and uses the bones as a simple mechanical lever system to move the body and its parts. All together with the muscles

    Although your teeth are also considered part of your skeletal system, they are not counted as bones. Your teeth consist of enamel and dentin. Enamel is the strongest substance in your body. The main priority of the skeletal system is to provide support for the body. Without bones our body would be in a pile of guts and mush on the floor. Your skeleton furthermore assists to protect your internal organs and fragile body tissues. The brain, eyes, heart, lungs and spinal cord are all sheltered by your

    The skeletal system is composed of two hundred and six bones in the human body. Functions such as the tendons, cartilage, and ligaments connect the bones and tissues together. Bone tissues make up about 18% of the weight of the human body. There are two types of tissue inside the bones. They consist of; compact bone and spongy bone. First, compact bone depicts the main shaft of long bones in the human body such as the arms and legs. Its tissue is dense and hard and it also makes up the outer layer of most bones in our body. Meanwhile, spongy bone tissue is made up of smaller plates occupied with red bone marrow. Mostly, it is found at the ends of long bones such as the head of the femur.
