Recommended: Axial vs. appendicular skeleton worksheet

Our skeleton has 5 main functions they are to protect our vital organs (heart and lungs), provide shape and structure, storage of calcium, movement, and it produces blood cells.
Our bodies are made up of two main skeletons, the Axial skeleton and the appendicular skeleton which both have different functions
The axial skeleton is the central point of the body; movement evolves around this axis. It consists of 80 bones, there are 29 bones altogether in the cranium as well as 24 bones in the ribs and 1 as the sternum. 26 bones as the vertebral column, 24 being the vertebrae as well as the sacrum and the coccyx. The functions of the axial skeleton are that it helps to support and protect the organs as well as creating a surface of attachment …show more content…

As an embryo, your bones are mainly made up of cartilage. They are very soft and therefore are extremely fragile. Ossification is a process that uses calcium, as the child grows, to create bone. Gradually as ossification occurs bones get stronger and harder.
Osteoblasts are cells that form in the marrow of bones. Osteoblasts are vital in forming bones when a foetus is developing and as a child grows. The bone cells don't stop working even once a person has reached adulthood, bone development occurs throughout your whole life. Also, the development of new tissue allows broken bones to repair.
Osteoclasts break down and reabsorb bone. As age increases bones strength decreases and they become more fragile and brittle, if this gets to a severe stage it is called osteoporosis. They are large bone cells formed in the marrow of a bone and although the number of them is small they are vital for the formation of new bones. As these cells break down they release calcium into the blood stream. Osteoclasts also aid the development of red blood cells the bone marrow.
After new bone tissue has been built, the remaining osteoblasts that don’t become cell lining become osteocytes. Osteocytes direct mineral deposits and send osteoclasts to repair any damaged bone …show more content…

    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

    An osteoblast is a “baby” bone cell whose main job is to secrete osteoid which forms the hardened, or calcified, bone matrix. Osteocytes are formed from osteoblasts. Osteocytes are the mature bones cells that have been completely differentiated. They are found in the lacunae of hard bone and have a spider-like appearance due to their canaliculi. Osteoclasts are a different type of cell formed from the mesenchymal cells. These cells are not related to osteoblasts or osteocytes. Their job is to basically “eat” the bone to create cavities and other hallow spaces during bone remodeling. Finally, the cells form differentiate to form fibroblasts and fibrocytes. These fibroblasts and fibrocytes secrete and form the matrix for fibrous connective tissue which is an essential component of the

    The musculoskeletal system offers support and stability for your body so we can properly function and move around. Different types of muscle within the muscular system include cardiac, skeletal, and smooth. The reason our bodies are capable of producing movement is because of the way our muscles contract. Our adult skeletal structure is made up of 206 bones that all differ in shapes and sizes. The composing parts that make up the system include the bones, joints, and muscles that all connect so we’re capable of moving. These components allow for our bodies to maintain a stable structure that can keep us upright. The axial skeleton refers to the skull, the vertebral column which supports the spinal cord, ribs, and sternum. It offers protections

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.

  • Causes Of Osteoporosis

    1125 Words  | 3 Pages

    Osteoporosis is a serious disease that leads to a faster than normal loss of the bone density, which puts the bone at a higher risk for fractures. In order to understand the causes of Osteoporosis, it is important to understand how bones are formed. Bone is a living tissue that is made mainly of collagen, calcium phosphate, and calcium carbonate. The mixture of collagen and calcium gives the bone strength and flexibility. The body deposits new bones and removes old ones; moreover, there are two types of bone cells that control the reproduction of bones. Cells called osteoclasts breakdown bone tissues thus, damaging the bone. Once the damaged bone is removed, cells called osteoblasts, use minerals including calcium and phosphate from the blood stream to make new healthy bone tissues. In order for osteoblasts and osteoclasts to work properly, hormones such us thyroid, estrogen, testosterone, and growth hormones are

    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 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 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.
