About This Quiz & Worksheet

Your ability to identify skeletal muscles structures will be assessed in this interactive quiz and accompanying worksheet. You will be asked to define myofilament, fascicle, myofibril, sarcomere, transverse tubules, and perimysium.

Quiz & Worksheet Goals

Use this test to assess your ability to identify

  • Characteristics of muscles fiber
  • The functional unit of skeletal muscle
  • The structure that carries neural impulses
  • The name of the connective tissue layer surrounding a fascicle
  • The repeating unit that runs end-to-end along the length of a myofibril

Skills Practiced

This assessment will test the following skills:

  • Reading comprehension - ensure that you draw the most important information from the related lesson on skeletal muscle organization
  • Critical thinking - apply relevant concepts to examine information about muscle movement in a different light
  • Defining key concepts - ensure that you can accurately define myofilament, fascicle, myofibril, sarcomere, transverse tubules, perimysium, endomysium, and epimysium
  • Distinguishing differences - compare and contrast fascicular and microscopic arrangement of muscle tissue
  • Information recall - access the knowledge you've gained regarding the structures of skeletal muscles

Additional Learning

Skeletal muscles are organized in a complex system of individual fibers bundled together. Learn more in the accompanying lesson called Skeletal Muscle Organization: Connective Tissue and Layers. The lesson covers the following objectives:

  • Recall fascicular arrangement
  • Define tendons
  • Explain how the muscles receive nutrients
  • Recall microscopic arrangement
