Muscle, Nervous, Immune,Lymphatic

Which of the following is a way that the skeletal system is necessary for the muscular system's function?

• the skeletal system has joints, which are what the muscular system pulls on to move

• the skeletal system provides structure for the muscular system

• the skeletal system provides calcium, which the muscles require along with ATP to contract

• all of the above

The muscular system interacts with the skeletal system by:

• smooth muscles are joined with spongy bone via cartilage

• skeletal muscles pull on joints to permit movement

• cardiac muscle is connected to the ribs

• skeletal muscles are joined to one another via ligaments

Each unit in a muscle fiber is called a __________.

• myosin

• globular heads

• sarcomeres

• troponin

A bundle of muscle fibers is called __________.

• Sarcomere
• Fascicle
• Tendon
• Muscle body

List the structures of a muscle from largest to smallest.

• myofibril, muscle fiber, fascicle

• fascicle, muscle fiber, myofibril

• fascicle, sarcomere, muscle fiber

• myofibril, fascicle, sarcomere

The situation in which a muscle loses its ability to contract, due to being used strenuously for a long period of time

• muscle pain

• muscle cramp

• muscle fatigue

• oxygen debt

The muscle that contracts during movement is called the

• agonist

• antagonist

• synergist

• flexor

What is the main effect of strength training?

• Muscle atrophy
• Muscle Hypertrophy
• Muscular dystrophy
• None of these

How do pairs of skeletal muscles work together?

• while one contracts, the other returns to original length
• both muscles contract at the same time
• both muscles relax at the same time
• 1 muscle pulls on the bone and the other pulls on the first muscle

Which number represents the Fascicle?
