Skeletal and Muscular Systems Flashcards
What is the Axial skeleton made up of?
cranium, vertebrae, ribs
What is the appendicular skeleton made up of?
all bones in the, shoulders, hips, arms and legs
Which type of joint are crucial in sport and exercise as they allow free movement?
Synovial joint
Describe the structure of a ligament
it’s a tough band of slightly elastic connective tissue
What is the function of a ligament?
They connect bone to bone and stabilise the joint during movement
What is synovial fluid?
A lubricating liquid contained within the joint cavity
What is the function of synovial fluid?
Reduces friction and nourishes articular cartilage
What is a joint capsule?
a fibrous sac with an inner synovial membrane
What Is the function of a joint capsule?
it encloses and strengthens the joint secreting synovial fluid
What is a Bursa?
A closed, fluid-filled sac found where tendons rub over bones
What is the function of a bursa?
It reduces friction between tendons and bones
What is a joint?
an area where 2 or more bones articulate to create human movement
What is articular cartilage?
smooth tissue which covers the surface of articulating bones
What is the function of articular cartilage?
it absorbs shock and allows friction-free movement
Identify the 3 planes of movement
sagittal plane, frontal plane, transverse plane
