Muscular System Pretest

Which parts of your muscular system are voluntary? Select ALL that apply.

• cardiac muscle

• skeletal muscle

• smooth muscle

• none of the above

Which parts of the muscular system have striations? select ALL that apply

• cardiac muscle

• skeletal muscle

• smooth muscle

• none of the above

The muscular system interacts with the skeletal system by:

• smooth muscles are joined with spongy bone via cartilage

• skeletal muscles pull on joints to permit movement

• cardiac muscle is connected to the ribs

• skeletal muscles are joined to one another via ligaments

Point of origin refers to .......

• the place where the muscles attach to the bone, but no movement occurs

• the place where the muscles attach the and movement occurs

• where a muscle attaches to another muscle

• the membrane the covers and supports muscles

The sliding filament theory explains which of the following?

• muscle extensions

• muscle inductions

• muscle contractions

• muscle formation

Which of the following puts the structures of the muscle in order from largest to smallest?

• Whole muscle, muscle fiber, actin & myosin, myofibril, muscle fasicle

• Whole muscle, muscle fasicle, muscle fiber, myofibril, actin & myosin

• Whole muscle, muscle fiber, muscle fasicle, myofibril, actin & myosin

• Whole muscle, muscle fasicle, muscle fiber, actin & myosin, myofibril

Which of the following is a way that the skeletal system is necessary for the muscular system's function?

• the skeletal system has joints, which are what the muscular system pulls on to move

• the skeletal system provides structure for the muscular system

• the skeletal system provides calcium, which the muscles require along with ATP to contract

• all of the above

Bradykinesia

• uncoordinated movement

• excessive movement

• slow movement

• shortening of a muscle

Smooth muscle lacks:

• ATP

• calcium

• involuntary contractions

• striation

I am a muscle attached to a bone. I am a voluntary muscle. I appear striped under the microscope. What kind of muscle am I?

• skeletal

• smooth

• cardiac

• memory
