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
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 skeletal system is an anatomical body system which consists of all the bones and joints in our bodies. In total, an adult body entails 206 distinct bones, arranged in the axial skeleton (80) and the appendicular skeleton (126). The latter division has bones in the limbs, pelvic girdle and the shoulder girdle, whilst the rest of the bones belong to the axial division. It’s a very important system therefore it has a few main functions. The most obvious is that it gives the body its rigid shape, which makes it relevant to other body functions like breathing, which is helped by the rib cage expanding to accommodate the movement of the lungs. Other functions include support to ensure that organs
Bone Homeostasis is the bones regulation spefic process Inorder to allow the body to function properly.
There are 206 different bones in the skeleton. (25 Doctors, 2017) The main bones are:
Many other body system are interrelated to the musculoskeletal system, which including skeletal, muscular, nervous, and digestive and circulatory system. Receptors in the muscles provide the brain with information about body position and movement. The nervous system controls the contraction of the muscles. The nervous system regulates the speed at which food moves through the digestive tract. The smooth muscles of the walls of the digestive organs rhythmically and efficiently move food through out the digestive system into other parts of the body. The muscular system works closely with the nervous system.
They also differ in the types of bones that make up their individual skeletons. Axial skeleton consists of bones from the skull, vertebral column, ribs and sternum and the appendicular skeleton consists of bones from the limbs, pelvis girdle, and pectoral girdle. The skeletal system is crucial for the human body to continue functioning and maintaining homeostasis.
The coccyx is a triangular-shaped bone located in the axial skeleton at the end of the spine and is inferior to the sacrum. This bone is really a set of small of bones (usually four, but could be three or five) that fuse during development. Since it is shaped like a tail, it is generally referred to as the tailbone. I found it fascinating that genetic research found that the same genes that produce the tails of mice also are responsible for the development of the coccyx. If ever there is a point to be made for evolution, the coccyx is it. I bet we were some awesome-looking creatures in ancient times – moving around, twitching our little tails!
At the microscopic level, the anatomy of the bones are fairly simple. Bones are made of osteons which can be classified into two sections, woven bone and lamellar bone. Lamellar bone is most common and when it’s
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 vertebral column is made up of 33 vertebrae that unite together to form a singular structure. The Vertebral column lies in the middle of the body, from the base of the skull to just below the hip bones. The vertebral column is split into five separate sections. The Cervical, made up of 7 vertebrae, Thoracic, 12 vertebrae, Lumber, 5, Sacrum, 5 fused vertebrae and the coccyx, 4 more fused vertebrae. Each individual vertebral are separated by interverbral discs are joined together by ligaments and muscles.

The skeletal system frames our entire bodies and protects our fragile inner organs. We have two major types of bone in our body: compact bone and spongy bone. Compact bone is dense and looks smooth, while spongy bone is comprised of small needle-like pieces of bone with lots of open spaces. Our body contains 206 bones. The skeleton is separated into axial and appendicular sections. The axial skeleton includes the bones in the longitudinal axis of our body. The appendicular skeleton consists of the limbs and girdles of the body, such as our arms and shoulders. There are four different classifications of bone, determined by their shape. Long bones are shafts with ‘heads’ on both sides. Our limbs contain mostly long bones. Short bones
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 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.
There is two divisions of the bones, the axial skeleton and the appendicular skeleton. The axial skeleton consists of 80 bones which include the skull, vertebral column, ribs and sternum. The skull considts of 22 bones. The cranium which cover the brain are made up of 8 bones and the facial is made up of 14 bones.
