anatomical movement
What are the two main divisions of the human skeleton?
Axial and appendicular
what are 3 types of muscle contractions?
concentric, eccentric, and isometric
what laws are used to analyze motion?
newton's laws of motion
Movement occurs in what, while rotation occurs along what?
planes and axes
which contraction involves the muscle shortening?
concentric
what type of motion moves in a straight line?
linear motion
which plane divides the body into left and right halves?
sagittal plane
which contraction involves the muscle lengthening under tension?
eccentric
what type of motions involves
what is a positive feedback loop
movement occurs in planes and around the axis... what axis is perpendicular to the sagittal plane?
frontal axis
druing the lowering phase of a bicep curl, what type of contraction is occurring and why?
eccentric contraction because the muscle is lengthening under tension
the ripening of fruit
what is a positive feedback loop
during a jumping jack, what plane and axis are primarily involved?
frontal plane and sagittal axis
how do different muscle contractions contribute differently to movement and stability?
Concentric creates movement, eccentric controls/decelerates movement, and isometric stabilizing joints
regulation of blood glucose levels
what is a negative feedback loop
