What is musculoskeletal system?
The musculoskeletal system, also known as the locomotor system, is the system which involves around the body’s structure and the movement of bones via the use of muscles in the body. This system has many parts such as muscles, bone structure, ligaments, cartilage, tendons, joints and other connective tissues involved in this system.
Structure of the bones
The bones are one of the most important structures in the musculoskeletal system as it supports the body, provides the body a form and provides stability. There are 206 bones in the body which protects the vital organs such as the heart, lungs and other vital organs as well as the skull which protects the brain. Bones also allows the body to store minerals and within a bone there is bone marrow located in the middle of the bone and this produces white blood cells (WBC), red blood cells (RBC) and platelets. The types of bones are skull, spine, chest, arms, legs, hands, pelvis, and feet.

There are 3 types of bones in human body, the fibrous, cartilaginous and the synovial joint. The fibrous joints are immovable such as the skull and are held together by ligaments. The cartilaginous joint is partially movable such as the vertebrates in our spine and their connection with one and another and can classified into 2 types of cartilaginous joints, synchondroses and sympheses. Synchondroses joints are joints that are temporary joints that are found in children until the end of puberty while sympheses joints are permanent joints such as the pubic symphesis. Synovial joints are joints that a freely movable such as the 6 common known joints in our body, which
The musculoskeletal system provides support for the body as it provides protection, protecting the body from any possible damage. The limbs of the body, e.g. arms, legs, hips and shoulders help support and keep the body held up. Many other bones support different parts of the body such as the rib cage supports and protects all the organs which are located inside the rib cage, such as the heart, lungs, kidneys and others. The shape of the skeleton allows us to cope with
Introduction. The skeletal system consists of the bones, along with the cartilage and fibrous connective tissue that make up the ligaments that connect bones to bone at joints.
The skeleton provides the framework of the body and it is made up of 206 bones. It is part of the skeletal system, which is composed of ligaments and cartilages, in addition to bones. Bones are connective tissues made of osseous materials that undergo calcification, a process where minerals are deposited to harden the bone. Cartilages are thick and rubbery tissues that are found in joints, the ears, the nose, and the ribs. Ligaments are tough, fibrous tissues that connect one bone to another bone, while tendons are soft tissues that connect muscles to bones.
2. The Skeletal and Muscular systems - The skeletal system’s goal is to give the body posture. However, the muscular system connects to the bone and helps move the arm. For example, Biceps and triceps connect to the shoulder and the radius and ulna to lift and lower your arm. In order for proper function, your body must only contract either the biceps or triceps at once. Additionally, the biceps and triceps would lie limp without the support from the bone. This is because the muscle can only constrict and relax. For this reason, they can’t move any limb without bones.
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
Hugo Münsterberg was a pioneer in several fields of medicine and psychology, including what is known today as forensic psychology. Münsterberg collaborated with many influential psychologists who helped shape his works and ideas, yet he is relatively unrecognized for much of his work. Through a brief investigation of his early life, educational history, and professional career, this essay will assess the notable procedures and events Münsterberg took and participated in that ultimately contributed to his foundation and support of psychology and law.
Form and function are essentially what make up anatomy and physiology. Anatomy focuses on the structure of the body. Physiology focuses on how the parts of the body function. With that said, it is important to understand how they work together in specific aspects of the body. A muscle fiber is structurally organized to produce tension by pulling on the tendons of the body. Depending on the direction and amount of pull there is on the tendon depends on how much force is exerted and the angle it is exerted at. Bone matrix can provide flexibility and compressive strength at the same time because they have more than one function. Bone matrix is the makeup of bone tissues that consist of collagen fibers. Without bone matrix, the makeup of the bones in the body itself would not be functioning or complete. The reason we can be flexible is because of the collagen fibers in our bones. Cartilage on the other hand is what allows us to resist compression and provide compressive strength. The flexibility and compressive strength aspect intertwine in working together to be able to perform both tasks. Another aspect of form and function to focus on is how joint structure affects strength specifically resistance to dislocation and flexibility (type and range of motion). The way a joint is set up allows a certain range of motion. The range of motion the joint allows is what usually people base peoples flexibility on. The range of
In Macbeth, by William Shakespeare, Lady Macbeth is the most ambitious because she will deceive the king by acting innocent, changing her characteristics to become more manly to get what she wants, and persuading Macbeth to kill the king so that she can become Queen. In the first aspect of her plan she says, “Look like the’ innocent flower, but be the serpent under’t.” (Macbeth 56-58). This reveals the ambition in her plan to commit the act of killing to achieve the status of being Queen she eagerly awaits. The innocence being of her actions hide the evil she has planned to unfold when the time is proper. It shows her initiative to get what she wants by acting one way but executing another. Another aspect of her plan is when she says, “Unsex
There are 5 types of bones in the skeletal system these are called long, short, flat, irregular and sesamoid bones. As shown in figure 9, long bones are longer than they are wide. They are 2 regions that form this bone, these are called epiphysis they is located at the top and bottom of the bone, and diaphysis that is located in the middle. These bones are located in places such as the femur, tibia, fibula, phalanges and ulna. Short bones are long as they are wide. These include the tarsal and wrist bones. Flat bones are broad bones
Among those sentenced to capital punishment, though, the rate of conviction is far higher than for any other category of criminal conviction. Less than one-tenth of 1% of convictions in our country are death sentences, yet they account for a shockingly high number of exonerations. Approximately 12% of known exonerations of innocent defendants from 1989 through early 2012 were of those on death row. One main reason for this high exoneration rate among capital cases is that far more resources and attention are devoted to death penalty cases, both before and after conviction, than to other criminal prosecutions. Almost all capital convictions are decided by a jury trial, and in the small number of capital cases where defendants plead guilty they
The human skeletal system consists of exactly 206 bones, it also contains tendons, ligaments, and cartilage that connects them together. The skeletal system performs vital functions such as support, movement, protection, blood cell production, calcium storage, and endocrine regulation. Infants are born with 270 bones, but some of them fuse together as the body develops. A bone in the skeletal system are typically dense and tough on the outside, like a compact bone. When going deeper in the bone the next layer is called spongy bone, which is lighter and more flexible. Some of these bones contain bone
Synovial joints are the most common joints in the skeletal system and are also known as the freely moveable joints. They are not directly connected which is why it allows a great amount of movement. As with most other joints in the body, synovial joints achieve more movements. The synovial joints consist of six different types of joints.
The microscopical anatomy of compact bone are composed of osteon, canals/canaliculi, and interstitial and circumferential lamellae. The osteon is considered the structural unit of the bone, which is wrapped in bone matrix called lamellae. These cylinder-reminiscent structures act as pillar to bear weight. Canals perforate though the center of osteons and are filled with blood vessels and nerve fibers. Interstitial and circumferential lamellae help fill gaps between osteons and provide support to long bones against twisting. Spongy bone has no particular structure and is scattered. Its function is help cushion bones and stores bone between its trabeculae. These significant features help bone tissue thrive its role of assisting support, but factors like diet, age, and environment can cause the decay and brittleness of the bone which later leads to the condition of
Ligaments and joints. Functions of the skeletal system; supports body and is the framework that the skeletal muscles use in order to cause movement, protection of organs (e.g. the rib cage encloses the heart and lungs forming a protective barrier and enclosing them within a cavity for surrounded protection), haematopoiesis is made in the cavities of bone and mineral storage also occurs with bones. An adult human has at least 206 bones in the body, with four categories of bones that include long, short, flat, irregular. These are made up of two types of bones dense or compact and spongy. Bones are composed of mineral deposits which provide stability and cells which give somebody the use of flexibility. If calcium and magnesium are not sufficiently provided for in the diet, these minerals will be taken from the bones causing the bones to slowly lose their density and deteriorate over time due to this as a result. Joints are protected with a cartilage covering and lubricating fluid, which helps avoid the bones from grating against one another. For example between the vertebrae in the spine, disks act as shock absorbers. The muscles and ligaments surrounding joints provide stability so they do not give in when in use. Joints require regular use to remain flexible, but they should not be overextended. Joint cartilage, ligaments and tendons are not repaired as quickly and easily as other parts of the body as they are not well supplied
There are about 206 bones within a human body that has reached adulthood. These bones play a
