The musculoskeletal allows the body to function through a group of muscles, bones, tendons, cartilage and ligaments. The body moves through different muscle contractions. This makes the bone pull towards the contracting muscles. The skeletal system provides a structure for the body, while the muscular system creates movement in the bones of the skeletal system by contracting and relaxing. When exercising, the muscles increase in pliability. This is when the muscles become more pliable as they become warm, reducing the chance of getting an injury. They become more pliable as the muscles contract really fast when exercising. The contractions generate heat take makes the muscle more pliable.
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
which impulses travels between the central nervous system and other parts of the body. The nerves in this subsystem connects the central nervous system to sensory organs (eye, ear) and to the other organs of the body. After studying the interesting body system we call the nervous system, I can conclude that the three main jobs for the
This system consists of both the skeletal and muscular system. They work together in unison to help our body produce movement, stabilize bones and give the body support, and pump blood cells. The bones have skeletal muscles that help produce movement. With the joints they act like fulcrums while the bones and muscles work and act like a lever. Depending on how close or far away of the load to the joint make the bones and muscles create a mechanical advantage or disadvantage when lifting an object. The bone that is stationary is the skeletal system. The skeletal muscles are attached by bones by tendons which help move the body. The tendon is a strong tissue used to produce movement. It doesn't stretch. Most of the time the tendon fastens a muscle to a bone. For example, the muscle on the upper part of the arm, is known as the biceps, is pulled together by a tendon to the bones just below the elbow. When the biceps becomes shorter, the tendon holds fast and pulls up the lower arm. On the back of the arm is triceps. When the muscle contracts, it pulls and straightens the arm. This is how a person is able to walk, raise and lower the head, and much more. The bone marrow produces leukocytes and erythrocytes while the muscular system pumps it out to the cells in the body. Now the skeletal system and muscular system gives our body our shape and stability. The muscles in the muscular system like the skeletal muscles and tendons help the bones in the skeletal system have their for a and shape so they would not fall and collapse. These are the interactions of both the skeletal and muscular
The musculoskeletal system is a made up of the muscular system and the skeletal system. The skeletal system provides the internal framework for the body, it protects the organs by enclosing it and anchors skeletal muscles so that the muscles can contract thus causing movement. The skeleton is divided into two divisions: the axial skeleton and the appendicular skeleton (Taylor & Cohen, 2013, p. 94). The Axial skeleton are the bones that have formed the longitudinal axis of the body which is made up of the skull, the vertebral column and the thoracic cage (Taylor & Cohen, 2013, p. 98). The Appendicular skeleton are the bones of limbs and griddles that are attached to the axial skeleton (Taylor & Cohen, 2013, p. 103).
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 framework of the human body is the skeletal system. Skeletal system organs include the bones, joints, cartilages, ligaments, tendons and teeth. Bones offer support for the muscles, protect our vital organs, and allow us to eat food. Our joints allow our body to move, twist and bend. Cartilage, like our ears and nose, offer soft structures that are more malleable than bones. Two separate bones are connected by ligaments, and bones and muscles are connected by tendons. Our teeth allow us to bite and chew our food. Skeletal structure is similar among all people around the world, with the greatest diversity occurring between the sexes. We will explore each system in greater detail and provide
The frame work of our entire skeletal system is called the skeleton and it comprises mostly of bones. Bones are inflexible and strong providing structure and support to our body, without which we would be just another huge blob on the floor! Bones also provide the structure for muscles to attach so that our bodies are able to move about easily for which all the bones in out body link to form joints that permit proper movement. Our skeleton also protects out internal organs from getting damaged easily by providing a protective cover around it. A fully grown human skeleton consists of 206 bones whereas a new born baby has around 300-350 parts.
The musculoskeletal system is made up of bones and joints which are held together by ligaments and tendons. Tendons and ligaments can be damaged by stretching and pulling, for example, when transferring a service user without the aid of a hoist. They enable the body to move and engage in physical activities. (See diagram 1 above).It also includes the spinal cord in (diagram 2) which is located in the back. The spinal cord contains all the nerves that enable the body to function. It is protected by the spinal columns which consist of bones known as
Calcium is critically involved in muscle contraction, nerve impulse transmission, and many metabolic activities within cells. To remain healthy, the body must keep the level of free calcium ions (Ca2+) within a very narrow concentration range. Besides providing a framework for the body, bone acts as a calcium "bank." When excess calcium is present in the blood, osteoblasts deposit it into bones where it is stored. When too little calcium is present, osteoblasts dissolve calcium from bones and move it into the blood. This process is controlled mainly by parathyroid hormone (PTH) secreted by the parathyroid glands in the neck. As people age, various conditions cause them to take more calcium out of the "bone bank" than they deposit, and osteoporosis (which literally means porous bones) eventually develops. A person's peak bone mass and the rate at which they lose it in later life affects their risk of developing osteoporosis; the higher the peak bone mass at age 30, the lower the risk of osteoporosis later on.
The continuous high levels of PTH stimulate bone resorption by osteoclasts, but do so indirectly. The PTH will bind to the receptors located on the osteoblast, which then signal bone marrow-derived osteoclast precursors to differentiate into osteoclasts. This is done through the activity of RANKL binding to RANK. When stimulated by PTH, the osteoblasts up-regulate expression of RANKL which binds to RANK and activates osteoclast production. This process will result in high bone turnover and ultimately, bone resorption. Overall, there will be more activity in the resorption phase of the bone remodeling cycle.
These hormones assist calcium in replacing and renewing old bone cells. Elevated levels of parathyroid hormone (hyperparathyroidism) causes calcium to leech from the bones into surrounding cells, where it is eliminated by the urine. This contributes to a decrease in bone density, which may cause osteoporosis.
The musculoskeletal involves the muscles and skeletal system which consist of bones supporting the bodyweight. The muscles and bones help in movement and maintaining body position through the physiological process of contraction and relaxation, muscles pulling on the bones. The skeletal systems also consist of cartilages and ligaments important for bone connection and stability with connective tissue. The muscles get attached to the bone by the connective tissue enhancing contraction and relaxation in movement. The muscles contain long muscle fibers responsible for the contraction and relaxation. The fibers contain bundles some of which allow slow movement described as slow twitch and fast twitch which ensure fast movement. The process of movement involves coordination between the musculoskeletal system and nervous system. In the process of muscle contraction to enhance movement the following takes place. (Arthur Guyton, 2006)
Hexapede are approximately “2 meters long” (6.56 foot) and “2.4 meters tall” (7.87) (Pandorapedia , 2016). They are vertebrates with endoskeleton structure. Starting from its head, the skull is small and sloped with symmetrical fan lobed-like structure on the skull. The neck consists of cervical vertebrae. Along its back lies scapula thoracic, vertebrae, lumbar vertebrae, sacro and pelvis. Its tail: caudal vertebrae. Attached to its back is the rib cage. Hexapede has six limbs therefore, the front and middle limb consist of (4) humerus bone, (4) Ulna, (4) radii, (4) carpi, (4) metacarpi and 4 phalanges. Its back limbs consist of (2) femurs, (2) rotula, (2) tibias, (2) fibula, (2) tarsi, (2) metatarsi and (2) phalanges.
To start off, the muscular system is what allows the body to move. Muscles are attached to the bones of the skeletal system and are made up of skeletal muscle tissue, blood vessels, tendons, and nerves. There are roughly 700 of them and each one is a discrete organ, together they make up approximately half of a person’s body weight (“Muscular System”).
