The flexor digitorum profundus
Flexor digitorum profundus
The gastronemius muscle is one of the calf muscles and it plantar flexes the foot or flexes the knee.
The extensor digiti minimi extends the minimum digit, ie. it straightens the interphalangeal joints of the pinky finger.
Origin is typically the proximal attachment of a muscle because it is the least moveable. The distal attachment is where a muscle inserts.

quadricep
A skeletal muscle with its proximal attachments near the joint or joints at which it acts, and its distal attachments at some distance from the joints, so that the greater part of its force is directed along the bones, tending to pull joint surfaces together. This makes shunt muscles good stabilizers.
Abductor muscle - moves a limb away from the midlineAdductor muscle - moves a limb towards the midlineExtensor muscle - increase the angle at a joint - extends a limbFlexor muscle - decreases the angle at a joint - flexes a limbPronator muscle - turns a limb to face downwardsSupinator muscle - turns a limb to face upwardsRotator muscle - rotates a limbIn the human body, these are the responsible muscles.*Muscles which move the thigh and their action*Gluteus maximus - Extends and rotates thigh laterally.Adductor longus - Adducts, medially rotates and flexes the thighAdductor brevis - Adducts, laterally rotates and flexes the thighAdductor magnus - Adducts, flexes, laterally rotates and extends the thigh.Rectus femoris - Extends knee and flexes hipVastus lateralis - Extends kneeVastus medialis - Extends kneeVastus intermedius - Extends kneeSartorius - Flexes knee. Flexes hip and rotates femur laterallyBiceps femoris - Flexes leg and extends thighSemitendinosus - Flexes leg and extends thighSemimembranosus - Flexes leg and extends thigh
