What is a covalent compound made of many small repeating units linked together in a chain? A polymer would fit that description. Also, a protein which is made of many amino acids hooded together by a peptide bond, which is a covalent bond.
Hip abductors are muscles on the other side of the leg and they do the opposite motion, by bringing the leg away from the middle of the body. It would look funny if humans stood around adducting and abducting their leg, but itâs more complex than thatâ¦.
Hip abduction occurs when the femur moves outward to the side, as in taking the thighs apart. Hip adduction occurs when the femur moves back to the midline. Many muscles contribute to these movements: 1  Medial rotation of the hip is carried out by gluteus medius and gluteus minimus. 2  The psoas is the primary hip flexor, assisted by the iliacus. 3  The pectineus, the adductors longus, brevis, and magnus, as well as the tensor fasciae latae are also involved in flexion.
