The Structure Of The Skeletal System

The skeletal system is made up of cartilage and bone. Both bone and cartilage are connective tissues, that is, they are composed of cells in a matrix with intracellular fibers. Just imagine connective tissue as a gelatin salad with grapes and coconut. The grapes would represent cells, the gelatin the support material for matrix, and the pieces of coconut the intracellular fibers. By changing the amounts of each ingredient and adding extra substances, we can produce a material that is very hard like bone and can withstand weight or softer like cartilage which can be used as a cushioning material.

Compact bone forms the outer layer of the bone and spongy bone is surrounded by the compact bone. On close examination, the compact bone had thin lines of closely packed materials making it hard to compress, while the spongy bone appeared like a network and was soft to touch. This is because spongy bone are made up of thin cells (trabeculae) separated by spaces (lacunae). For color difference, compact bone is cream colored while spongy bone is reddish in color.

It also protect soft internal organs for an example brain and heart from injury. Skeleton with muscle is strong bones that can enable the body to move freely. Individuals who is at increase risk for fractures may be difficult to heal because of the weakened bones. This can lead to loss of mobility, the inability to retain independent living and even death. Osteoporosis can gives a huge effect to human skeletal due to decreased mineralization of the bone. Human skeletal consist of two types of bones which is compact bones and spongy bones. Compact bones is a bone that has a solid outer surface while spongy bone is inner bone that less dense than compact bone which has many holes like sponge. A spongy bone does not have osteon.The matrix forms an open network of trabeculae. Healthy bone is dense enough to support and protect body and to handle stresses of movement and minor injuries while osteoporosis has abnormally thin bones with larger holes on spongy

In this content am going to be talking and explaining the structure and function of the skeletal system. I will be talking about: Axial skeleton, Appendicular. Also highlighting the different types of bone such as long bones, short bones flat bones, irregular bones and sesamoid bones. I am also going to be talking about how your body is

The skeleton produces blood cells. Red bone marrow contains stem cells that produce all of the blood cells.

Exploring the Skeletal System The precise number of bones in the adult human skeleton varies from one person to another, but on average there are 206 bones varying shapes and sizes. The skeleton is divided into two main parts. The central bones of the skull, ribs, spin (vertebral column) and breast bone (sternum) form the axial skeleton. The bones of the arms and legs, along with the shoulder blade (scapula), collar bone (clavicle) and pelvis make up the appendicular skeleton.

Generally, bone can be classified into two categories according to its structure, cortical (compact) and trabecular (cancellous or spongy) bone. Cortical bone is stiff, with 5–10% porosity, and it makes up approximately 80% of skeletal bone, including cuboidal bones, flat bones, and the ends of long bones. Cortical bone is much denser, stiffer, and stronger than trabecular bone. The average strength of a compact human bone was 105 MPa in a longitudinal compression test, and was 131 MPa in a transversal compression test. In the same experiment, the average longitudinal strength in tension was 53 MPa [39]. In contrast, the porosity of trabecular bone is approximately 50–95%, which is higher than that of cortical bones. The surface area of the

There are approximately two hundred six bones in our body and they're essential in our life. Bones consists of osseous tissue, nervous tissue, and epithelial and muscle tissue. Examples are the femur, humerus, clavicle, and sternum. The bones have many different functions in our bodies, but basically, their main functions are to provide support and protection for the body. Bones provide a framework that supports our body and bones such as skull, vertebrae and rib cage try to prevent internal organs from injuries. Also, bones enable movement by providing points of attachment for muscles and they produce blood cells, also known as hematopoiesis in the red marrow. Lastly, bones store minerals, such as calcium and phosphorus for different cellular activities and store lipids in adipose cells of the yellow marrow as an energy reservoir. There are different shapes and textures of bones. Bones can be flat, such as scapula and sternum, or irregular like the sphenoid bone and vertebra. Also, bones can be short or long. Examples of short bones are the carpal bone and talus and long bones are ulna, femur, and radius. In terms of texture, bones can be compact or spongy. Compact bones are dense and heavy while spongy bones are porous and light. Both types of bones are connective tissues. Usually compact bones are the out layer of a bone and spongy bones are the internal portion of the bone.

This paper will discuss the composition and cells of bone, different types and organization of bone, bone remodeling, bone development in children, and bone fractures

The skeletal system is one of the body’s most important support systems. When anomalies occur within the bone structure, the entire body suffers. One such anomaly is the condition known as osteogenesis imperfecta or brittle bone disease. Osteogenesis imperfecta (OI) is a hereditary, genetic disorder of the bones and connective tissues that is most known for causing fragile, brittle bones which can break hundreds of times in one’s lifetime. This rare disease “occurs in approximately 1 in every 12,000-15,000 births” (Knipe et al., n.d.) and “affects between 20,000 and 50,000 people here in the United States” (Osteogenesis Imperfecta Foundation, 2015).

First, we need to understand what a bone actually is. You can hear bone-dry on a daily basis but actually bones are actually quite alive with nerves , blood vessels etc. Without bones in our body we would just be a blob and unable to move anything in our body. A bone divides into three layers periosteum, haversian canals and bone marrow. The first layer is the periosteum layer, it covers the whole part of the bone minus areas where cartilage connects the bone to a joint. The second layer is known as the Haversian canal which transports nerves and blood vessels throughout the human body. The third layer is known as compact bone or spongy bone, spongy

The skeletal system is made up of bones and joints. Bones are a dry dense tissue that is composed of calcium phosphorous and organic matter. The bones are protected and covered by a layer of fibrous connective tissue membrane called the periosteum (Brown, et al., 2015, p. 1547). There are two basic types of bone tissue: Compact Bone and Spongy Bone. Compact bones are dense smooth bones, while Spongy bones are composed of small needle-like pieces of bones and open space. Bones are then categorised according to the shape of the bone into four groups: long, short, flat and irregular. Long bones characteristically are typically longer then they are wide and generally have a shaft with heads at either ends e.g. the humerus. They are mainly compact bones. Short bones

Bone serves the organism at multiple levels: As a system, bones permit the organism to locomote effectively and to maintain posture by bearing loads without deformation, by providing rigid attachment sites for muscles and acting as a system of levers to amplify small movements. As an organ, bones protect the viscera and house the hemopoietic tissue (red marrow). As a tissue, bones serve as a reservoir of readily mobilizable calcium, an

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.
