• Skeletal Muscle

Multiple Choice

What is the primary characteristic of multi-unit smooth muscle movement?

• Muscle cells move together

• Muscle cells move independently

• Nerves do not send signals

• Muscle cells are connected

Multiple Choice

What is the primary function of smooth muscle cells single unit type?

• To contract individually

• To move as a group

• To transmit signals

• To connect to bones

Multiple Choice

What are the pathways called that allows single unit smooth muscles to all work together?

• Gap Junctions

• Multi Unit

• Voluntary

• Involuntary

Multiple Choice

What are the key characteristics of cardiac muscle as described in the image?

• Branched shape, multiple nuclei, non-striated

• Branched shape, one nucleus, striated

• Straight shape, one nucleus, striated

• Branched shape, multiple nuclei, striated

Multiple Choice

What is the function of cardiac muscle?

• To absorb nutrients

• To propel blood

• To store oxygen

• To filter waste

Multiple Select

What type of movement is associated with cardiac muscle?

• Voluntary

• Involuntary

• Rhythmic

• Skeletal

Multiple Choice

What is another name for a heart muscle cell?

• cardiomyocytes

• Gap Junctions

• sodium (Na+) channels

• Actin Filaments

Multiple Choice

What causes the sarcomeres to shorten and the muscle to contract?

• Nerve signals

• Hormonal signals

• Filaments

• DNA replication

Multiple Choice

What are the characteristics of skeletal muscle as described in the image?

• Long & cylindrical

• Multinucleated

• Clear striations

• All of the above

Multiple Choice

What role do myosin and actin filaments play in muscle contraction?

• They provide energy for contraction

• They contract when nerve impulses signal them to

• They transport oxygen in the blood

• They are involved in nerve signal transmission

Multiple Choice

What is the function of the sarcomere in muscle cells?

• Energy production

• Contraction

• Cell division

• Protein synthesis

Multiple Choice

What is the role of calcium ions in sarcomere contraction?

• They provide energy for contraction

• They bind to troponin to expose binding sites for myosin

• They break down ATP

• They transport oxygen to muscles

Multiple Choice

What sends a nerve impulse to the muscle tissue?

• The heart

• The brain or spinal cord

• The lungs

• The stomach

Multiple Choice

What is the neurotransmitter that is released into the muscular filament during muscle contraction? (give full name OR 3 letter abbreviation)

• Myosin

• saromere

• Junction

• Acetylcholine

Multiple Choice

The image shows.....

• The neuromuscular junction

• Where bone joins muscle

• Cell division

• Fertilization

Multiple Choice

What does myosin do for the muscles to contract

• It pulls on the actin to contract the muscle

• It releases acetylcholine into the muscle

• It allows the actin to slide along its pathway for contraction

• It provides a pathway for electrical signals

Multiple Choice

Which muscles are involuntary?

• skeletal
• cardiac
• smooth
• smooth and cardiac

Multiple Choice

Which type of muscle is under voluntary control?

• Smooth muscle

• Cardiac muscle

• Skeletal muscle
