Functions, Types of Contractions & Effects of Exercise

Muscle contraction without joint movement: (a)  

• Isometric
• Isotonic
• Twitch
• Tetanic

Check all the other body systems involved in movement:

• Respiratory

• Nervous

• Urinary

• Skeletal

• Cardiovascular

The phase of a muscle contraction where the muscle shortens: (a)  

• Isometric
• Concentric
• Eccentric
• Twitch

The phase of a muscle contraction where the muscle lengthens: (a)  

• Isometric
• Isokinetic
• Concentric
• Eccentric

A sustained muscle contraction is also known as a:

• Twitch Contraction

• Tetanic Contraction

• Threshold

• Motor Unit

• Spasm or Cramp

The main muscle responsible for movement is called the: (a)  

• Synergist
• Antagonist
• Prime Mover
• Action

The muscle that assists another muscle during movement: (a)  

• Synergist
• Antagonist
• Prime Mover
• Motor Unit

The muscle that relaxes while the prime mover is contracting: (a)  

• Motor Unit
• Synergist
• Antagonist
• Insertion

The point of contact between the nerve ending and the muscle fiber: (a)  

• Motor Unit
• Neuromuscular Junction
• Motor Nerve
• Threshold Stimulus

Minimal level of stimulation required to cause a muscle to contract: (a)  

• All or None Response
• Threshold Stimulus
• Tetanic Contractiin
• Twitch Contraction
