Define my scientific terms

dorsiflex(1)- Dorsiflexion is the movement which decreases the angle between the dorsum (superior surface) of the foot and the leg, so that the toes are brought closer to the shin. The movement moving in opposite directions is called plantarflexion.
plantarflexion(2)-Plantarflexion (or plantar flexion) is the movement which increases the approximate 90 degree angle between the front part of the foot and the shin, as when depressing an automobile pedal.
Elevate(3)- To raise (something) to a higher position; to lift.
hyperextend(4)- extend a joint beyond its normal range
ulnary deviating(5)- bending your wrist toward your little finger.
supinating(6)-turn (the hand or forearm) so that the back is downward or backward.
Transverse plane(7)- The transverse plane is an imaginary plane that divides the body into superior and inferior parts. It is perpendicular to the coronal and sagittal planes.
shoulder joint(8)- a ball-and-socket joint between the head of the humerus and a cavity of the scapula.
Radially deviate(9)- bending your wrist towards your thumb.
adducted(10)- Adduction is a movement which brings a part of the anatomy closer to the sagittal plane of the body. It is opposed to abduction.
flexion(11)- act of bending a joint; especially a joint between the bones of a limb so that the angle between them is decreased.
pronated(12)- turn the forearm or the hand so that the palm is directed downwards.
laterally rotate(13)- is rotation away from the center of the body.
medially rotate(14)- rotation towards the center of the body.
extending(15)- is a movement of a joint that results in increased angle between two bones or body surfaces at a joint.
range of motion(16)- The distance and angles at which joints can be moved, extended and rotated in various directions.
eversion(17)- Eversion is the movement of the sole of the foot away from the median plane.
inversion(18)- Inversion is the movement of the sole towards the median plane.
superior limb(19)- upper limb, example: arm.
Sagittal plane(20)- A sagittal plane is an imaginary plane that travels vertically from the top to the bottom of the body, dividing it into left and right portions.

Exercise #3

Begin by positioning yourself as if you were going to do a push up, with an exercise ball raising your legs off the ground. Your feet should be hanging just over the edge of the ball. Keep your body straight as you bring your knees towards your chest.Roll the ball a few inches forward with your ankles as you bring your knees into your chest, then return to the starting position. This is a challenging exercise because it is hard to keep your center of gravity equal with your legs on the exercise ball, especially when you start to roll the ball forward. Try a few sets with short reps until you are comfortable with the movement.

Excercise #2

Exercise number 2 is single leg squats. In strength training, the squat is an exercise that trains primarily the muscles of the thighs, hips and buttocks, hamstrings as well as strengthening the bones, ligaments and insertion of the tendons throughout the lower body. Squats are considered a vital exercise for increasing the strength and size of the legs and buttocks. Video taken from Sagittal plane(20) view. Use a superior limb(19) for stability. Keep your toes pointed straight ahead and avoid any inversion(18) or eversion(17).
