1
Q

Ligaments

A

The role of it is to join bone to bone. They are formed of tough connective tissue that holds the bone together to form a joint.

Q

Tendons

A

The role of it is to join (skeletal) muscle to bone. Tendons are formed of a tough connective tissue. Tendons are relevant to sport and physical activity because:
They hold muscle to bone so that went the muscle contracts the muscle can pull on the bone and cause movement at joint

Q

Cardiac muscles

A

Location: Cardiac muscles
Cardiac muscles are unconsciously controlled - we don’t have to think to make it contract.
E.g. - Cardiac muscles in the heart contracts to pump blood around the blood.

Q

Voluntary muscles

A

Location: Voluntary muscles are the skeletal muscles that attach via tendons to the skeleton to allow movement.
Voluntary muscles are under conscious control - we move them when we want to; consciously decide when they should work
E.g. - the biceps contract to flex the arm at the elbow when we perform biceps curls

Q

Involuntary muscles

A

Location: Involuntary muscles are found in blood vessels (and the stomach and intestines)
They contract slowly and rhythmically and are unconsciously controlled - they contract automatically when required to by the body.
E.g The involuntary muscles in the blood vessels help regulate blood flow vascular shunting
