Muscle Types
100

Every muscle has these two attachment points

What are the origin and insertion?

100

This muscle is involved in flexing the elbow joint.

What is the Biceps Brachii?

100

The connective rope-like tissue that connects muscle to bone. 

What is a tendon?

100

More involvement of these will increase the force of a muscle contraction

What are motor units(or muscle fibers)?

100
Is involuntary and lacks striations

What is smooth muscle?

200

The Sliding Filament Theory of muscle contraction involves these two filaments.

What are Actin and Myosin?

200

This muscle group is the antagonist in flexing the knee joint

What is the quadriceps group?

200

The smallest contractile unit in a muscle.

What is a sarcomere?

200

This molecule is the involved in muscle contractions allowing the cells to relax.

What is ATP (Adenosine Triphosphate)?

200

Is voluntary and has striations.

What is skeletal muscle?

300

Muscle contraction potentially fails due to these two causes.

What is no ATP or Oxygen debt?
300

The name for this muscle comes from the Latin for "three heads"

What is the Triceps Brachii?

300
The outermost lining on a muscle.

What is the epimysium/fascia?

300

This is production of ATP in the presence of oxygen.

What is aerobic respiration?

300

This muscle type is multinucleate.

What is skeletal muscle?

400

This is a muscle contraction in a laboratory setting involving only one muscle fiber that fully contracts and fully relaxes.

What is a twitch?

400

This the longest muscle in the human body.

What is the sartorius muscle?

400

The flattened sheath-like connective tissue attaching muscle to some anchor point.

What is aponeurosis?

400

Cellular respiration that produces ATP outside of the mitochondria.

What is Anaerobic Respiration?

400

Is arranged in longitudinal and cross-sectional fashion.

What is smooth muscle?

500

This results from the summing or contracting of muscle fibers where no relaxation occurs before being stimulated again.

What is Fused Complete Tetanus (Tetany)?

500

This muscle has it's origins on the maxilla bone and frontal bone and is involved in blinking the eyelids.

What is the orbicularis oculi?

500

These are the myofibrils in muscle tissue

What are Actin and Myosin?

500

The production of this molecule during anaerobic respiration decreases pH.

What is lactic acid?

500
Has one nucleus per cell, is striated, and involuntary.

What is cardiac muscle?
