This activity includes a two-page worksheet and a full-page table that reinforces both the naming system (nomenclature) of muscles and identification of muscle characteristics from the breakdown of the muscle name.
In the first worksheet, students identify six characteristics that affect the naming of skeletal muscles. Then they match the muscle name with the appropriate shape description. In the next section, students match the muscle name with the correct direction of fibers. In the ensuing section, students match the muscle name with the correct size description. In a similar fashion, students match the muscle name with the proper function. Students then record the number of origins for three given muscle names that offer prefix clues of the number. In the last section, students state the actions for the following muscles since some muscles are named in part due to their action: abductor, adductor, flexor, extensor, levator, and masseter. Altogether, eight main questions in the worksheet require thirty-six answers.
In the Breaking Down Comprehensive Names of Muscles Table, students identify the characteristic(s) off which the provided muscle is named, then specify the meaning of the characteristic(s) in each example. Students perform this task for fourteen muscles, following the filled in example.
A three-page color-coated answer key is provided.
