Mobility in Humans THE MOVEMENT SYSTEM  MOBILITY IN HUMANS (MOVEMENT SYSTEM) Humans have physiological body functions that interact and cooperate with each other, including the mobility process which consists of the movement system and the nervous system. In the subchapter of the movement system also known as the musculoskeletal system, the discussion includes things that are directly related to the mobility process, including the introduction of the types of bones and skeletons that are discussed briefly, the types of joints and muscle movement mechanisms to support movement, of course, connected with the discussion of the relationship between phenomena in the mobility process which includes abnormalities, disorders or diseases. LEARNING OBJECTIVES Student will able to: 1. Propose hypotheses about the relationship between organs in the movement system and their functions through observations. 2. Analyze abnormalities or disorders in the movement system through interpretation of information or data. 3. Analyze the relationship between the movement system and the nervous system based on data from investigations in scientific articles about conditions of disorders or disorders in humans.  Movement System Skeletal Muscle System System THE SKELETON BONES SONG  Functions Protects our organs (brain, intestines, etc.) Provides a framework for the movement of our body through our muscles Stores minerals that our body needs to function properly Produces blood cells  Divisions of Skeleton Axial Skeleton: consists of the 80 bones that make up the trunk of our body. Appendicular Skeleton: consists of the other 126 bones in the human body and make up our limbs.  Axial Skeleton Sections: Skull Spine (vertebral column) Ribcage  Appendicular Sections: Skeleton Arms and hands (upper extremities) Legs and feet (lower extremities) Shoulders Hips (pelvis) Shape of Bones  Sesamoid Bone A sesamoid bone is a small bone commonly found embedded within a muscle or tendon near joint surfaces, existing as focal areas of ossification and functioning as a pulley to alleviate stress on that particular muscle  Bones Bones have two inside parts: Compact bone Cancellous, or spongy, bone So named because of its holey appearance. Types of tissue that form bones Compact bone: – Supports the whole body – Protects organs – Provides levers for movement – Stores and releases chemical elements (calcium) – Dense, smooth and very strong – Contains living cells which help make repairs if a bone is injured or broken. Types of tissue that form bones Cancellous/spongy bone: – Typically occurs at the ends of long bones, proximal to joints and within the interior of vertebrae – Spongy and light weight – Also, like compact bone, contains living cells which help make repairs if a bone is injured or broken.  Ligaments The tissue that connects bones to other bones  Joints Joint: location where two or more bones make contact. Joints allow movement and provide mechanical support. There is a cartilage cushion in between the bones to keep them from touching directly – which would hurt!  Joints Examples of Joints  Tendons Muscle Tendons: attach muscles to bone. They are made out of a tough Tendo n connective tissue and are capable of stretching to allow Bone for movement. Function of the muscular system : Provides movement in conjunction with the skeletal system Important in life support Used by humans for food Type of Muscles  Movements produced by skeletal muscle contractions Flexion vs extension Abduction vs Adduction Pronation VS Supination Elevation VS Depression Rotation FLEXION VS EXTENSION ABDUCTION VS ADDUCTION PRONATION VS SUPINATION ELEVATION VS DEPRESSION ROTATION  Abnormalities Skeletal Muscle Please read the following scientific journal: https://www.medicalnewstoday.com/articl es/musculoskeletal-disorders Please make a mind mapping in your notebook as one of your assignments, then take a photo and send it through GCR.
