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
To begin with, the muscular system basically makes movement. Every step you take, every time you blink your eyes and eve when you swallow food, that is the muscular system doing its job. The muscular system also helps maintain homeostasis by maintaining body temperature which happens when you contract, which is the shortening of a muscle while pulling against the bones, you are releasing heat which is helping regulate your body temperature. Another job that the muscular system has is maintaining our body’s posture. These are some examples of involuntary things that your bones do, meaning that they do it without you personally consciously controlling them. Some examples of voluntary movement, which is when you're consciously controlling it,
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).
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
With out the support we wouldn’t be able to function in the right way. The skeletal system is very important because of the bones that are found in our body, nearly all bones hold our vital organs in place whilst you are moving.
The Skeletal System The skeletal system works as the frame of the body and it is made up of two hundred and six various bones. The Sections used in the movements of the skeletal system are; the bones, Joints, ligaments and tendons. This system is also divided into two sections known as the Axial and Appendicular skeleton.

Chapter 5: The Skeletal System I. 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 skeletal system works with almost all the systems, providing them with a protective barrier by enclosing all the major organs, like the brain, heart,
Criteria 1.2 Explain the relationship between the structure and function of the human skeleton. ANSWER: The skeleton is the framework of bones, it structures the body, support to the body and protects the internal organs of the body. It also allows the muscles to move freely during the mechanism of locomotion.
The musculoskeletal system is an organ system that gives humans the ability to move, using the muscular and skeletal systems. It provides form, support, stability, and movement to the body. The musculoskeletal system is made up of the body's bones (the skeleton), muscles, tendons, ligaments, joints, and other connective tissue that supports and binds tissues and organs together. Its primary functions include supporting the body, allowing motion, and protecting vital organs. Most importantly, the system provides form, support, stability, and movement to the body. For example, the bones of the skeletal system protect the body's internal organs and support the weight of the body. The skeletal portion of the system serves as the main storage depot
The skeletal system can be a wonder to many people, because of how much the bones of the body can endure, and even how a small fall can cause a break or a fracture. The human body has 206 bones, a complex system of tendons, ligaments and cartilage that connect
In mammals, there are an abundant amount of varying systems and components that all work together in order for the body to function properly and sustain life; one of those components that have a great portion of responsibility is the skeletal muscle. Skeletal muscle is responsible for a great portion of movements of the body, such as transportation, obtaining food, and fight or flight responses. Muscles are composed myofibrils, which when grouped together forms muscle fibers and when those are grouped together they form muscles fascicles; multiple muscle fascicles are formed together to form skeletal muscles. All skeletal muscles are motor neuron-dependent and composed of muscle fibers that are innervated by a motor axon and together form what is known as the motor unit. The muscle fibers all work together to form a muscle contraction, which is initiated by a neuronal action potential. The action potential can be activated one of two ways, it can be either voluntary by the person or it can be in voluntary, which would include electrical stimulation to the peripheral nerve. After the action potential is initiated, a neurotransmitter is released in the neuromuscular junction, which results in the depolarization of the muscle or a contraction (Schiaffino, Blaauw, & Dyar, 2016).
The skeletal system includes the osseous tissues of the body and the connective tissues that stabilize or interconnect the individual bones. The bone is a dynamic tissue. Throughout the lifespan, bone adjusts to the physiologic and mechanical demands placed on it by the processes of growth and remodeling.
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.
