Body Movement/Types of Body Movement
across
Body movement occurs when muscles contract ________ joints.
2
Muscles are attached to no fewer than ______ points.
attachment to a movable bone
Regarding muscle movement, what is the insertion?
attachment to an immovable or less movable bone
Regarding muscle movement, what is the origin?
With a few exceptions, all skeletal muscles cross at least one joint Typically, the bulk of a skeletal muscle lies proximal to the joint crossed All skeletal muscles have at least two attachments: origin and insertion Skeletal muscles can only pull; they never push During contraction, a skeletal muscle insertion moves toward the origin
What are the 5 rules of muscle movement?
Abduction

Rotation
What body movement is represented by this image?
Opposition
What body movement is shown?
movement of a joint away from the midline; adduction
What is abduction, and what is the opposite of it?
movement of a limb toward the midline; abduction
What is adduction, and what is the opposite of it?
combination of flexion, extension, abduction, and adduction; common in ball-and-socket joints; proximal end of bone is stationary, and distal end moves in a circle
What is circumduction (what combination of movements, what joint is it common in, how do the distal and proximal ends move)?
lifting the foot so that the superior surface approaches the shin (toward the dorsum); plantar flexion
What is dorisflextion, and what is it the opposite of?
turning the sole of the foot laterally (away from body); inversion
What is eversion, and what is the opposite of it?
increase in the angle between two bones, typical of straightening the elbow or knee; flexion
What is extension, and what is the opposite of it?
decrease in the angle of a joint, brings two bones closer together, typical of bending hinge joints; extension
What is flexion, and what is the opposite of it?
extension beyond 180 degrees, moving body past anatomical position
What is hyperextension?
turning sole of foot medially (toward the body); eversion
What is inversion, and what is the opposite of it?
moving the thumb to touch the tips of other fingers on the same hand
What is opposition?
pointing the toes away from head; dorisflexion
What is plantar flexion, and what is the opposite of it?
forearm rotates medially so palm faces posteriorly, radius and ulna cross each other like an X; supination
What is pronation, and what is the opposite of it?
movement of a bone around its longitudinal axis, common in ball-and-socket joints
What is rotation?
forearm rotates laterally so palm faces anteriorly, radius and ulna are parallel; pronation
What is supination, and what is the opposite of it?
shaking your head "no"
What movement is a common example of rotation?
knee and elbow
What two joints are common with flexion and extension?
insertion; origin
When the muscle contracts, the ____ moves toward the ______.
