From wrist to fingers, what is the order of bones

• Carpals, phalanges, metacarpals

• Metacarpals, carpals, phalanges

• Phalanges, metacarpals, carpals

• Carpals, metacarpals, phalanges

Identify the highlighted bone

• Clavicle

• Scapula

• Mandible

• Ilium

Identify the highlighted bone

• Femur

• Ulna

• Radius

• Humerus

Identify the highlighted muscle

• Deltoids

• Erector spinae

• Latissimus dorsi

• Trapezius

What best describes ligaments?

• Connective tissue attaching muscle to bone

• Soft tissue that connects bone to bone

• Occurs where the muscle attaches to a bone that is pulled by the action of the muscle

• Site where the muscle attaches to a stable bone

What best describes tendons?

• Connective tissue attaching muscle to bone

• Soft tissue that connects bone to bone

• Site where the muscle attaches to a stable bone

• Occurs where the muscle attaches to a bone that is pulled by the action of the muscle

What best describes origin?

• Soft tissue that connects bone to bone

• Occurs where the muscle attaches to a bone that is pulled by the action of the muscle

• Site where the muscle attaches to a stable bone

• Connective tissue attaching muscle to bone

What best describes insertion?

• Occurs where the muscle attaches to a bone that is pulled by the action of the muscle

• Soft tissue that connects bone to bone

• Site where the muscle attaches to a stable bone

• Connective tissue attaching muscle to bone

What is a convergent fibre arrangement?

• Fibres that are short and attach obliquely to a central tendon that runs the length of the muscle

• fascicular pattern is circular

• The length of the fascicles runs parallel to the long axis of the muscle

• A muscle that has a broad origin and fascicles that come together to a single tendon of insertion

Which of the following best describes a multipennate fibre arrangement?

• Fascicles look like many feathers side by side, all their quills inserted into one large tendon (e.g. deltoid)

• Fascicles insert into only one side of the tendon (e.g. extensor digitorum in the forearm)

• Fascicles inset into the tendon from opposite sides - resembles a feather (e.g. rectus femoris of the quadriceps)
