Musculo-Skeletal System Flashcards
What is the musculo-skeletal system?
The musculo-skeletal system includes all the bones in the body. Attached to the skeleton is a muscular system. Working together, the joints, bones and skeletal muscles of the body comprise.
What is the musculo-skeletal system used for in sport?
The musculo-skeletal system provides stability, posture and protection.
What are the five functions of the skeleton for sport?
Protection, blood cell production, joints for movement, muscle attachment and storing minerals.
How does our skeleton protects our vital organs?
The skull protects the brain, the spine protects the spinal cord, and the ribs protect the internal organs, including your heart. These bones act as cages around important body parts.
What’s the benefit of muscle attachment in relation to sport?
The muscles you use in sport need strong points to attach to. Bones provide that framework. The muscles are attached by tendons.
Why are joints important in sport?
Joints let the body make a variety of movements (kicking a football). Joints work together with bones and muscles to form levers.
Why is mineral storage important for sport?
Calcium and phosphorus maintain the strong and healthy bones that you need for exercise. Food examples: cheese, yogurt, milk, etc.
Why is red and white blood cell production important?
Bone marrow makes most of the cells of the blood, including red blood cells, white blood cells and platelets. Bone marrow responds to your activity and condition to keep you in good shape.
What are the three bones in your arm called?
Radius, Ulna and Humerus
What are the three bones in your foot?
Tarsals, Metatarsals and Phalanges
What is the bone in the knee called?
Patella
What are the three bones in the leg called?
Femur, tibula and fibula
What are the three bones in your hand?
Carpals, Metacarpals and Phelanges
What is the technical term for the skull?
The cranium
What is the bone in your shoulder?
Clavicle
What are the bones in your upper and lower jaw called?
Maxilla and Mandable
What is the name of the first seven bones in the vertebrae?
Cervical vertebrae
What is the name of the region of the vertebrae that has 12 bones.
Thoracic vertebrae
What are long bones?
Long bones are bones that are longer than they are wide. They don’t have to be big; finger bones (phalanges) count as long bones. A long bone has a shaft plus two ends.
Why are long bones vital in sport?
Long bones act as levers. These bones are vital to generate movement, strength and speed. An example of this, is kicking a football, the more power you put in the more powerful the shot is.
What are short bones?
Short bones are roughly the same size in length, width and thickness. Examples of this, are the carpals and tarsals.
Why are short bones important in sport?
They are shock absorbers. They play a key role in activities like jogging, playing tennis or dancing.
What are flat bones?
Flat bones are bones that usually protect organs or offer a good surface for muscles to attach to. For example, the ribs protect the heart and lungs.
Why are flat bones essential in sport?
Flat bones protect your vital organs, especially in contact sports. They also provide attachment of muscles to help movement for every type of physical exercise.
What are irregular bones?
Irregular bones have odd shapes, and perform a range of functions. Some have a special shape so that they can protect something, like the vertebrae, which protect the spinal cord.
Why are irregular bones essential in sport?
Irregular bones offer protection when you are playing sport- for example, vertebrae in your back protect the spinal cord.
What is the role of the intervertebral discs?
The intervertebral discs stop the bones from clashing. If a disc slips then the person will experience sharp pains in their back.
How many groups of vertebrae form the vertebrae column?
Five
