How is handwriting samples and signature samples compared?. . - Handwriting is more uneven and a signature is smooth.. 2. List the factors that can determine the identity of a writer, based on a handwriting sample.. Key Terms. Histology:. the study of tissues.. Tissues:. groups of cells which are similar in structure and which perform common or related functions.. Four Basic Kinds of Tissues. Epithelial Tissue. Factors that influence flexibility. 1- Joint structure. The type of joint determine the degree of ROM. For example; a ball-and-socket joint, like shoulder has greater ROM than a hinge joint like wrist. . Baseline (Flightpath D): .
