A&P
The prime mover for knee extension
Quadriceps
The resistance is between axis and force
A flight path symmetrical about its highest point caused by the dominant weight force of a projectile
Parabolic flight path
Insertion of the gluteus medius
The greater trochanter
Perpendicular distance from the fulcrum/axis to where the force is applied
Moment arm
The most favourable angle of release for a projectile to optimise lift force
Angle of attack
The rotator cuff muscles
Supraspinatus, infraspinatus, teres minor, subscapularis
This type of lever gives an advantage in velocity and range of motion (ROM)
Third class lever
The creation of an additional lift force on a projectiles in flight - the higher the velocity of air flow, the lower the air pressure.
Bernoulli’s Principle
The inward flow of these ions increases the concentration of positively charged cations in the cell and causes depolarization during an action potential
Sodium ions
The most common lever type in the human body
Third class lever
A force created from a pressure gradient on opposing surfaces of a spinning body moving through the air.
Magnus force
These are extensions of the cell membrane that penetrate into the center of skeletal muscle cells, permit rapid transmission of the action potential into the cell, and also play an important role in regulating cellular calcium concentration.
T-Tubules/transverse tubules
Occiput of skull on the axis (an example of which lever type)
First class lever
Three factors that influence the trajectory of a projectile
The angle of projection, the projection speed, and the relative height of projection
