The muscle in the picture responsible for our smile is called the:

• Buccinator

• Mentalis

• Masseter

• Zygomaticus

Tissue which is interwoven throughout muscle tissue and which binds muscles within their bundles is called:

• Biceps femoris

• Vastus Intermedius

• Vastus lateralis

Considered the longest muscle in the body as it wraps from lateral to medial is called the:

Once a nerve impulse travels down a motor nerve to the neuromuscular junction, the sarcoplasmic reticulum releases this component which causes the

proteins (troponin and tropomyosin) to move allowing the myosin heads to engage with the actin, this component is:

• Calcium

• Heme

• ADP

• ATP

When the myosin heads engage with the actin, this is referred to as a(n):

• Network

• Crossbridge

• Sync Link

• Connector
