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¦.
Innervation of the Pectoralis Minor. In order for a muscle to contract and function, it must receive electrical impulses from the brain through a nerve or group of nerves, a process that is called innervation. The pectoralis minor muscle is innervated by the medial pectoral nerve. The medial pectoral nerve contains nerve fibers from the eighth cervical nerve (C8), which comes from the spine in the lower part of the neck, and the first thoracic nerve (T1), which comes from the spine in the upper part of the back. Lesson Summary. The pectoralis minor muscle is a
