the answer is
D. Infraspinatus
The brachialis is a muscle in the upper arm that flexes the elbow joint.
There are actually four muscles which make up the shoulder adductors. These muscles include the Pectoralis Major, Coracobrachialis, Latissimus Dorsi, and Teres Major.
The deltoid muscle is the big muscle on the shoulder. It has three parts; the front or anterior, middle and back or posterior. It involves the shoulder joint.
in shoulder joint
It is a triangular muscle covering the shoulder joint, it raises the arm from the side of the body
its a joint that flexes
none as the joint ca[sule is an inert structure meaning no contractile tissue
Adduction of upper arm at the shoulder
The psoas is one of the flexors of the hip.
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
its a joint that flexes
It plantar flexes the foot at the ankle and flexes the leg at the knee.
