Muscle Structure and Hierarchy

​Neuromuscular Junction and Muscle Contraction

​Muscle Contraction-Sliding Filament Theory

​Major Muscles

Multiple Choice

This type of muscle tissue is found only in the heart

• Skeletal

• Cardiac

• Smooth

Multiple Choice

This type of muscle tissue is attached to bones and helps control voluntary movement

• Skeletal

• Cardiac

• Smooth

Multiple Choice

This type of muscle tissue moves food through the digestive track

• Skeletal

• Cardiac

• Smooth

Multiple Choice

Each muscle fiber is directly surrounded by connective tissue called the 

• perimysium

• exomysium

• endomysium

• epimysium

Multiple Choice

What is the smallest unit in the muscle hierarchy?

• Fascicles

• Myofibrils

• Myofilaments

• Bundles

Multiple Choice

What is the relationship between myofibrils and myofilaments?

• Myofibrils are composed of myofilaments

• Myofilaments are composed of myofibrils

• They are the same structure

• Myofibrils create light bands

Multiple Choice

What is the neurotransmitter that crosses the gap to activate the muscle?

• Dopamine

• Serotonin

• Acetylcholine

• Norepinephrine

Multiple Choice

How do muscles produce movement?

• Muscles contract by pushing bones

• Muscles contract by pulling bones

• Muscles contract by pushing and pulling bones

• Muscles do not produce movement

Multiple Choice

Which of the following is NOT a function of the muscular system?

• Maintain posture

• Stabilize joints

• Generate heat

• Filter toxins and excess waste from blood

Multiple Choice

Which connective tissue wraps around the entire outside of the muscle?

• Perimysium

• Epimysium

• Endomysium

Multiple Choice

Which connective tissue wraps around the entire outside of each fascicle?

• Perimysium

• Epimysium

• Endomysium

Multiple Choice

Which connective tissue wraps around the entire outside of each muscle fiber?

• Perimysium

• Epimysium

• Endomysium

Multiple Choice

Which structure is C? (hint: whole bundle)

• Muscle fiber

• Fascicle

• Epimysium

• Perimysium

Multiple Choice

Which structure is B?

• Muscle

• Epimysium

• Muscle fiber

• Myofibril

Multiple Choice

What is the function of acetylcholine?

• ACh binds to receptors on the sarcolemma and opens ion channels

• ACh binds to receptors on the sarcolemma and closes ion channels

• ACh binds to ion channels and open them

• ACh binds to ion channels and closes them

Multiple Choice

Calcium inside the muscle cell binds to which filament, causing a shape change and revealing the active sites.

• Actin

• Myosin

• Troponin

• Tropomyosin

Multiple Choice

What binds to the active site on actin?

• Actin

• Myosin

• Troponin

• Tropomyosin

Multiple Choice

What is a cross-bridge?

• When troponin and tropomyosin undergo a shape change

• When the active site of actin is revealed

• When the myosin heads bind to the actin active site

• When the actin filaments slide past the myosin filaments

Multiple Select

When is ATP needed?

• When actin slides

• When myosin heads bind to actin

• When myosin heads release from actin

• When myosin slides
