The skeletal systems include both bones and joint. Its main purposes are to protect different organs and to support the body. In an adult body the skeletal system has 206 individual bones that are arranged into two major divisions: the axial skeleton and the appendicular skeleton. Each bone is made up of many cells, protein fibers, and minerals. The bone acts as a storage unit for things such as calcium, iron, and energy in the form of fat.
FULL SKELETON
Axial skeleton runs along the body’s midline axis and is made up of 80 bones in the following regions:
Skull – a framework of bone or cartilage enclosing the brain of a vertebrate; the skeleton of a person 's or animal 's head.
Hyoid- bone between the chin and thyroid in the neck
Auditory Ossicles- malleus, incus, and stapes located in the ear
Ribs- 12 on each side and 24 in total, 7 real and 5 false
Sternum- center of chest also called the breast bone vertebral column- also called spinal cord located in middle of the back
The appendicular skeleton is made up of 126 bones in the following regions:
Upper limbs- deltoid region to the hand
Lower limbs- hips to the toes

These 21 bones allowed children’s brains to grow. The upper bones are called the cranium; they offer protection for the brain. The lower bones are called the facial bones; they offer support for things such as your eyes, nose, and mouth. In the cranium there are 4 main bones two parietal (in the middle, one on each side), occipital (in the back), and frontal (in the front). However, the facial consists of 18 bones; two nasal, two lacrimal, two palatine, two interior nasal concha, two maxilla, two mandible, two temporal, and two zygomatic. There are six bones located inside your ear, but are not part of the skull. These bones are called malleus, incus, and stapes. They play an important role in helping with the sense of
However some of the basic bone functions include storing of crucial nutrients, minerals and lipids, producing red blood cells for the body, protect the organs such as heart, ribs and the brain, aide in movement and also to act as a buffer for pH. With the differences in all of the bones there are four things that remain the same in each bone, their cells. Bones are made up of four different cells; osteoblasts, osteoclasts, osteocytes and bone lining cells. Osteoblasts produce and secrete matrix proteins and then transport the minerals into the matrix. Osteoclasts are responsible for the breaking down of tissue. The osteoblasts and osteoclasts are both responsible for remodeling and rebuilding of bones as we grow and age. The production of osteoclasts for resorption is initiated by the hormone, the parathyroid hormone. Osteocytes are the mature versions of osteoblasts because they are trapped in the bone matrix they produced. The osteocytes that are trapped continue making bone to help with strength and the health of the bone matrix. The bone lining cells are found in the inactive bone surfaces which are typically found in
This report will explore the structure and function of skeletal muscle within the human body. There are three muscle classifications: smooth (looks smooth), cardiac (looks striated) and skeletal (looks striated). Smooth muscle is found within blood vessels, the gut and the intestines; it assists the movement of substances by contracting and relaxing, this is an involuntary effort. The heart is composed of cardiac muscle, which contracts rhythmically nonstop for the entire duration of a person’s life and again is an involuntary movement of the body. The main focus of this report is on skeletal muscle and the movement produced which is inflicted by conscious thought unless there is a potentially harmful stimulus and then reaction is due to reflex, as the body naturally wants to protect itself. Skeletal muscle is found attached to bones and when they contract and relax they produce movement, there is a specific process that the muscle fibers go through to allow this to occur.
The system of the body that consists of bones, connective tissues, and cartilage is known as the skeletal system. Some major functions of this system are as follows:
The skeletal system is composed of many bones, joints, cartilage, ligaments, and tendons. The key functions of the skeletal system are to supply a supportive frame for the body, to shield the internal organs such as the heart and lungs. Providing attachment points for muscles is also another function as this enables the parts of the animal to have good locomotion, the long bones produce bone marrow. However, for this report, I will be concentrating more on the joints of the canine skeletal system. The joints are the articular exteriors at the end of the bones, they are shielded by a coating of cartilage. There are three main types of joints within the canine skeletal system they consist of the fibrous joints, these do not allow any movement
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.
The Skeletal system performs vital functions; supports movement, protection, blood cell production, calcium storage and endocrine regulation. That enables the human body to survive.
The skeletal system is made of all the bones, connective tissues and joints in the body. Bones, cartilage are some of the bones that make up the Skeletal system. The Skeletal system helps perform important everyday functions, for example; support, movement and protection, etc. The skeletal system helps form blood cells. The skeletal system helps store calcium and phosphorus, which is important and beneficial to the other functions in the body.
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
The bony collar of long bones is the one that is designed to help support the weight of the body and withstand compressive stress.
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
Some of the organ systems of the body are the integumentary system, skeletal system, muscular system, nervous system, senses, and endocrine system. They are all equally as important to the survival of the human body. The first organ system that will be discussed is the integumentary system. The main purpose of the integumentary system is protection from infection, harmful rays of the sun, and cuts. Furthermore, the organs found in the integumentary system are the skin, hair, nails, sense receptors, sweat glands, and oil glands. The second organ system is the skeletal system. The skeletal system is made up of a total of 206 bones, 80 bones in the axial skeleton which is the trunk and head, and 126 bones in the appendicular skeleton which is the upper and lower extremities, and pelvis area. In addition, the main duties of the skeletal system are posture, aids muscles in movement, and heat production. The organs fou...
The two hundred and six bones in the human body produces a lot of blood cells, store important minerals such as homeostasis (storage and release), and also release hormones, which are necessary to life. During body movement, the skeletal system assists by contracting and pulling on bone to produce movement. Although, in the world we all live in today, skeleton symbolizes all kinds of means/significant reasons. From people using it as a symbol for death (Halloween, rituals, etc.), movies, and many other scary things, the real fact is that skeletal system is one of the most body’s most life giving systems. Apart from other living organs such as the skin, eyes, and many more, the bones are the main primary function that carries them all. Bones are sturdy and firm, but each one in our bodies has their own blood, lymphatic vessels, and nerves. Being the fact that the skeletal system makes up our body movements, support, and protection, it also has its
The musculoskeletal system can also be referred to as locomotive system. It mainly comprises of muscles, skeleton, tendons, cartilage, ligaments and joints. The musculoskeletal system supports the body, aids in movement of the body and protect the vital organs in the body.
Twenty-eight bones make up the skull. Eight of these bones are interlocking plates. These plates form the cranium.
The Skeletal System, also known as the Skeleton make up a framework that support the body and protect the organs. The Skeleton consists of the bones and joints of the body. In the human body there is 300 bones at birth, these then fuse together to make 206 bones in a fully grown adult. The Skeleton is made up of two divisions: The axial and appendicular Skeleton.
