Introduction to Kinesiology: Vocabulary and Concepts
Discuss details of the skeletal system as listed below and be prepared to discuss these with the class as you respond to other student’s discussion answers.
Define only TWO of the following subjects or terms in your own words. (20pts each) Your submission should be 12-15 sentences in total. You may refer to the lecture notes and/or book for more information. When
responding to other student’s answers, discuss what new insights you have learned. Select at least TWO other student posts. (10pts)
Axial & appendicular skeleton
Joints (cartilaginous joint, fibrous joint, synovial joints)
Classification of bone (long, short, flat, irregular)
Planes of the body (sagittal, frontal, transverse)
The body’s skeleton serves varying functions. Bone, also known as osseous tissue, is made of hard, connective tissue which creates the skeleton. Cartlidge then helps the body to move as it is placed in the bone’s joints. The skeleton also provides a base for our muscles to attach to. Since our bones are hard, they keep our organs protected inside from injury or harm to the outside of the body.
Joints take place in the body where two bones meet. Joints are the point of contact where our bones can flex and move. Joints may have varying degrees of stability, meaning a tighter ligament will be more capable of controlling joint movement. Three types of joints are cartilaginous, fibrous, and synovial. Cartilaginous joints take place when the joints are only met by cartilage. Fibrous joints are met by fibrous tissue instead of cartilage. Synovial joints are where bones can move against one another such as the shoulders, hip, elbows, etc.
Joints are the links between bones. Joints allow our body to move and bend, allowing fingers, wrists, arms, shoulders, legs, and hips to complete the actions we need in our daily life. Cartilage joints are covered with cartilage, which can reduce friction during exercise. At the same time, cartilage also has the elasticity to slow down vibration and impact during practice. Fibrous joints are bones connected by tight fibrous connective tissue. Synovial joints are composed of two or more bones and have excellent mobility.
Bones are divided into long, short, flat, and irregular bones. Long bones are distributed in limbs like legs, arms, and other parts that can participate in sports. Short bones are mainly distributed in hands and feet, which meet the human body’s daily needs. Flat bones are primarily in the head, chest, etc., mainly to protect the internal organs of the human body. , Irregular bones are distributed primarily in the spine and skull.
