Standard 3 Muscles

Muscles are attached to the bone at no less than ___ points

• 12

• 4

• 2

• 1

attached to the immovable or less moveable bone

• origin

• insertion

• flexor

• adductor

why do body movements occur

• movement of the bone around it's longitudinal access

• bones are more than 90 degrees apart

• muscles contract across joints

• opposing movement

mobility of the joint and location of the muscle in relation to the joint

• how a muscle's name is decided

• factors determining if the bone will move

• factors that determine type of movement

• what determines how the muscles will be held together

movement in the sagittal plane that decreases the angle of the joint and brings the bone closer together

• flexion

• extension

• rotation

• Abduction

movement increases the angle and brings bones farther away from each other and farther than 180 degrees

• adduction

• flexion

• extension

• inversion

combination of flexion, extension, abduction, and adduction. Proximal end of the limb is stationary and the distal end moves in a circle and the whole limb outlines a cone.

• eversion

• inversion

• circumduction

• rotation

• extension

• inversion

• eversion

• adduction

turn sole of foot laterally

• eversion

• inversion

• adduction

• rotation

bending knee or elbow

• abduction
