there is three main types of muscles,  skeletal, smooth and cardiac.

Muscles are attached to the skeleton

Muscles contract and pull bones making them move about a joint.]]> 2020-12-17 01:31:46 UTC https://padlet.com/gordon_quan/fk3p5knrhzsid9zj/wish/1026301096 Flexion, Extension karenng17 https://padlet.com/gordon_quan/fk3p5knrhzsid9zj/wish/1026302507 2020-12-17 01:32:22 UTC https://padlet.com/gordon_quan/fk3p5knrhzsid9zj/wish/1026302507 3 types of joint natalie_lam18 https://padlet.com/gordon_quan/fk3p5knrhzsid9zj/wish/1026304125 1) fixed or immoveable joints(fibrous joint)
- can't move at all 
- are found in skull(cranium)
-are joined as fibrous connective tissue
2)Slightly moveable joints(cartilaginous joint)
-can move a small amount
-linked to ligaments and cartilage(which absorbs movement)
-found in the vertebral column(spine) and the ribs
3) Freely moveable joints(synovial joints)
-Greater amount of movement 
-found in elbow, shoulder, knee, hip]]> 2020-12-17 01:33:05 UTC https://padlet.com/gordon_quan/fk3p5knrhzsid9zj/wish/1026304125 https://padlet.com/gordon_quan/fk3p5knrhzsid9zj/wish/1026307147 The main muscles in your body that move your bones are called voluntary muscles.

-found in shoulder and hips
-large range of movement
-allow actions e.g overhead clear, badminton 
2)hinge joints
-found in elbows and knees. Work same as hinges
-allow movement in one direction 
-elbows and knees let us do a jump shot in basketball
