Question

1. the inflammation of the tendon *

extensor
flexor
tendonitis
hernia

1. which is not a function of the skeletal system? *

protects internal tissues and organs
produces new red and white blood cells
prevents movement of limbs and digits
acts as a framework for attached muscles

1. which type of joint is a knee? *

ball - and - socket joint
hinge joint
pivot joint
ellipsoidal joint

Explanation:

• For question 9, tendonitis is the medical term for tendon inflammation. Extensor and flexor are types of muscles, and hernia is a different medical condition.
• For question 10, the skeletal system aids in movement, not prevents it. It protects organs, produces blood - cells, and provides a framework for muscles.
• For question 11, the knee is a hinge joint which allows movement primarily in one plane (flexion and extension). Ball - and - socket joints allow multi - directional movement (e.g., shoulder), pivot joints allow rotational movement (e.g., neck), and ellipsoidal joints allow movement in two planes (e.g., wrist).

Answer:

1. tendonitis
2. prevents movement of limbs and digits
3. hinge joint
