The study of how internal and external forces affect a living body (especially for the skeletal system)
A position above a point of reference.
A position below a point of reference.
A position near the center of your body or a point of reference. Your knee joint is more proximal to your hip joint then your ankle joint is.
A position that is farther away from the center of your body or point of reference. Your ankle is more distal to your hips then your knees are.
This refers to the front of your body facing forward. Your chest is anterior on your body.
This refers to the back of your body. Your back and your hamstrings are posterior.
This refers to things close to the midline of the body. Your adductors are closer to the midline of your body compared to your abductors.
Positioned on the outside of the body. Your ears are on the lateral side of your head.
These are things located on the opposite side of your body. Your left foot is contralateral to your right hand.
These are things located on the same side of your body. You are left foot is ipsilateral to your left hand.
The anatomic position is important as a point of reference for anatomic nomenclature. The anatomic position is when the body is erect, the arms at your side and your palms facing forward.
The sagittal plane splits the body into a right half and they left half. Extension and flexion are movements in this plane.
This is a bending movement where a relative angle between two adjacent sections decreases.
This is the opposite of flexion. The relative angle between adjacent sections increases
This is the extension beyond the normal limits of the body.
This is a vertical plane that has right angles compared to the sagittal plane breaking up the body between frontal and posterior planes.
The act that typically moves a limb away from the midline of the body in the frontal plane.
The act that typically moves a limb towards the midline of the body in the frontal plane.
The plane that divides the body into a lower and upper section.
When a limb rotates in the transverse plane going away from the midline of the body.
When a limb rotates in the transverse plane going towards the midline of the body.
Imagine the movement of a chest fly.
Imagine the movement of a rear deltoid fly.
The act of moving the shoulder blades away from the midline.
The act of moving the shoulder blades in the direction of the midline.
The act of elevating the shoulder blades towards the superior.
The active lowering the shoulder blades towards the inferior.
A concentric muscle action: happens when the contraction is accompanied by the shortening of the muscle tissue.
An eccentric muscle action: is accompanied by the lengthening of the muscle tissue.
In isometric muscle action is when no change in the length of the muscle happens.
in isokinetic muscle, action is when the contraction speed of a muscle is constant.
Any movement that results in the speeding up or slowing down of an object.
This is the perfect length of a muscle that will result in the most force produced. The ability of a muscle to produce force at its current range.
Something that tends to produce rotation or torsion. The movement of a system or force that typically leads to a rotation.
This is rotational movements from the joints.
Groups of muscles that work with one another in order to produce a force on a joint.
How the muscular and nervous system cooperates to gather and interpret information in order to execute the movement.
This is the cumulative sensory input to the CNS (Central nervous system) from all of the various mechanoreceptors that can sense limb movement and body position.
Muscles that are controlled by the central nervous system in order to produce the same movements.
The maturation of muscle coordination.
The process of improving one's motor skills with practice. This results in lasting changes and one's overall capability of responding.
The process where people use cognition in order to coordinate the muscles and limbs of the body.
Response to external and internal stimuli from the environment. The overall study of motor development, motor learning and motor control (a.k.a. movement).
This is information that one will get about their performance from external sources. Usually visual, verbal or written.
This is how you personally feel after you have practice or performed a certain skill.
This is a biological system where the response or the output affects the initial input.
The first type of lever
Is where the fulcrum sits directly between the energy moving the weight and the weight itself. Some good examples are scissors, seesaws, crowbars or a hammer extracting a nail.
The second type of lever
Is where the fulcrum is at one end, the weight is in the middle and the force is being applied on the other end. Some common levers that use this second type are wheelbarrows, can openers and staplers.
The third type of lever
Is where the fulcrum is on one end, the weight is on the other end and the forces being applied in the middle. With this type of lever, more force needs to be applied, but in return, the weight gets moved a much larger distance. Some good examples are a fishing rod, a broom or a baseball bat.
