There are five main functions of the skeleton.
Support
The skeleton provides the framework for the body, enabling it to maintain posture, which is the position of the body when standing or sitting. The main bone is the spine - a curved ‘S’ shaped bone which is made up of vertebrae. There are 7 vertebrae in the neck called cervical vertebrae which support the head and connect to the thoracic spine, which consists of 12 vertebrae and gives support and stability to the upper body. There are also 5 lumbar vertebrae which carry the majority of the weight from the upper body. Between each vertebra is a spongy disc that connects them together flexibly. The discs are smaller between the cervical vertebrae and larger between the lumbar vertebrae in the lower back because of the difference in the amount of weight to support.
Protection
Some of the bones in the skeleton are designed to protect the vital organs. The cranium protects the brain, which is the bodies master control unit. The ribcage and sternum protect the lungs which are vital for breathing and respiration; they also protect the heart which is vital for blood circulation and the liver which is vital for purification (cleansing our body of toxins) . The vertebrae protect the spinal cord which serves as our neurological transmission highway. The pelvis protects the urinary system which is vital for excretion (The act or process of discharging waste matter from the blood) and also protects our reproduction system which enables us to procreate.
Movement
The skeletal bones attach to each other by ligaments and are then attached to muscles by tendons. The muscular and skeletal system work together to carry out bodily movement and are jointly called the musculoskeletal system. When muscles contract, bones are pulled along to produce movement allowing people to walk or run. An example of this is the contraction and relaxation of the triceps and biceps which produces the effect of straightening the arm.
Study Guide for Chapter 10 Quiz Chapter 10 Muscle Tissue What are the 3 types of muscle tissue? Skeletal muscle tissue: Attached to the skeleton; comprise the muscular system, and allow us to move. Cardiac muscle tissue: Only present in heart. Smooth muscle tissue: Involuntary; present in internal organs (they are not organs in themselves) What are the 6 functions of skeletal muscle? Produce skeletal movement, Maintain posture and body position, Support soft tissues, Guard entrances and exits, Maintain…
the structure and function of the muscular system. The muscular system is made up of the muscles in the body, there are more than 600 and tendons that connect them to the skeleton. Function Movement Skeletal muscles are arranged in pairs on opposite sides of joints. As one muscle contracts, the opposing muscle must relax to cause movement. Posture Muscle are also needed to provide stability to the body. It is kept with the contraction of muscles e.g Heat Many skeletal muscles contract isometrically…
Principles of anatomy and physiology in sport The structure and function of the skeletal system In this essay I will be talking about the skeletal system, its functions including the axial and appendicular skeleton and the bones within the skeletal system shown within a diagram. These are the bones within the skeletal system (the locations of certain bones are shown by the labelled lines), there are 206 bones in the human body (Shown in the diagram above) the skeleton is divided into two groups…
Ch. 10 Exam Review 1. Specify the functions of skeletal muscle tissue. Produce skeletal movement, Maintain body position and posture, Support soft tissues, Guard openings, Maintain body temperature and Store nutrient reserves 2. Describe the organization of muscle at the tissue level. Muscles have three layers of connective tissues: Epimysium: exterior collagen layer, Separates muscle from surrounding tissues Perimysium: surrounds muscle fiber bundles (fascicles) Endomysium: surrounds individual…
production 3. Identify the sources of energy for muscle contraction 4. Explain how skeletal muscles support other body systems 5. Identify conditions that impair the healthy functioning of muscle systems 6. Describe the benefits of exercise for maintaining healthy muscles Magnificent Muscle Facts • The human body has more than 650 muscles. • Waste energy keeps you warm! • No two muscles in the body have exactly the same function. When one muscle is paralyzed, either stability of the body part is impaired…
SKELETAL SYSTEM Human skeletal system is commonly called the framework of the body; this is because it shapes the human body. This ‘framework’ consists of bones, cartilages and joints. Joints are a vital component of the skeletal system as it makes up the firm and stiff skeleton which enables different parts of the body to make various types of movements, therefore if the joints weren’t present in the skeleton; there would be no movement leading to the human body becoming rather insignificant.…
10 Major Neurotransmitters Neurotransmitters are powerful chemicals that regulate numerous physical and emotional processes such as mental performance, emotional states and pain response. Virtually all functions in life are controlled by neurotransmitters. They are the brain's chemical messengers.Interactions between neurotransmitters, hormones, and the brain chemicals have a profound influence on overall health and well-being. When our concentration and focus is good, we feel more directed, motivated…
our bodies unite us as human beings. But it is the tiny differences – from what’s going on inside, to what we experience on the outside – that can make us truly unique. Tissues are groups of similar cells working together to perform a specific function and are the living fabric that holds together the human design. In this course, you will examine the four main classifications of tissue – epithelial, connective, muscle and nervous – in more detail as we examine their specific role in human body…
