Muscles and Joints Flashcards
What is the skeletal/ striped and voluntary muscle? What is an example of it in the body?
- muscle that moves the skeleton (muscle that connects to your bones)
- example = biceps in the upper arm
what is the definition of a joint? What is an example of it in the body?
- where 2 bones meet together and enable movement of the skeleton
- example = elbow (hinge joint)
What is the extensor muscle? What is an example of it in the body?
A muscle that contracts to cause extension of a joint is called an extensor muscle
- example = straightening your elbow
What is a flexor muscle? What is an example of it in the body?
- (corresponding muscle to the extensor) flexor muscle contracts to reverse the movement
- it decreases the angle between bones on two sides of a joint
- example = bending of the elbow
What is an antagonistic pair of muscles? What is an example of it in the body?
- as one muscle contracts, the other muscle relaxes or lengthens = two muscles are needed to move a bone to and fro
- example = bicep and tricep
What is the synovial joint? What is an example of it in the body?
- that allows for free movement in multiple planes
- example = ball and socket
What is the synovial fluid? What is an example of it in the body?
What is the synovial membrane? What is an example of it in the body?
What is a ligament? What is an example of it in the body?
What is a tendon? What is an example of it in the body?
What is cartilage? What is an example of it in the body?
What is the fibrous capsule? What is an example of it in the body?
What is the gliding joint? What is an example of it in the body?
What is a pivot joint? What is an example of it in the body?
What is a fixed joint? What is an example of it in the body?
What is the ball and socket joint? What is an example of it in the body?
What is a hinge joint? What is an example of it in the body?
