Muscular System Quiz

What are the three major types of muscles in the muscular system?

• Skeletal, smooth, and nerve muscle

• Cardiac, smooth, and bone muscle

• Skeletal, cardiac, and smooth muscle

• Cardiac, nerve, and bone muscle

What are the functions of the muscular system?

• Movement of the body, maintain posture, and circulate substances

• Circulate blood, digest food, and cognitive function

• Protect organs, produce hormones, and absorb nutrients

• Generate heat, store nutrients, and filter waste

How is each muscle characterized in the body?

• As a flexible tissue connecting bones

• As a discrete organ with its own tissues, blood vessels, and nerves

• As a part of the skeletal structure

• As a type of fat tissue

What is the role of muscles in the movement of the skeletal system?

• Muscles stabilize joints during complex movements

• Muscles help keep the body in the correct position while sitting

• Muscles contract and pull on the bones of the skeletal system to produce voluntary movement

• Muscles provide a protective covering for internal organs

How do muscles contribute to the stability of the body?

• By contracting and pulling on the bones

• By working alongside tendons and ligaments to stabilize joints during complex movements

• By generating 85% of the body's heat

• By allowing for the movement of substances through ducts and vessels

What function do muscles serve in maintaining posture?

• They contract to produce voluntary movement

• They absorb shock at moving joints

• They generate body heat

• They help keep the body in the correct position while sitting, standing, or moving

What is one way muscles protect internal organs?

• By producing voluntary movement

• By providing a protective covering and absorbing shock at moving joints

• By generating heat during shivering

• By facilitating circulation of substances through ducts and vessels

How do muscles contribute to heat production in the body?

• By stabilizing joints during movements

• By helping maintain posture

• By contracting to generate 85% of the body's heat; shivering produces extra heat in cold temperatures

• By protecting internal organs

What role do muscles play in the circulation of substances within the body?

• They help maintain body posture

• They generate body heat

• They protect internal organs

• They allow for the movement of substances through ducts and vessels of other organ systems

What is contractility in the context of muscle characteristics?

• The ability to return to its original length

• The ability to stretch beyond its original length

• The ability to shorten and thicken with force

• The ability to respond to a stimulus
