Abnormality of skeletal morphology Abnormal tendon morphology Abnormal shape of tendon An abnormality of the structure or form of the tendons, also often called sinews. doelkens A tendon (or sinew) is a tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension. Tendons are similar to ligaments and fascia as they are all made of collagen except that ligaments join one bone to another bone, and fascia connect muscles to other muscles. Tendons and muscles work together and can only exert a pulling force. Abnormality of the sinew HP:0100261 human_phenotype UMLS:C4021026 2010-07-20T01:20:19Z
