What are the three types of muscle? -
correct answer ✅skeletal muscle, cardiac muscle, and smooth
muscle
What is the common property that all three types of muscle have? -
correct answer ✅they all exhibit a quality called excitability
What is excitability? -
correct answer ✅ability to undergo neural stimulation

correct answer ✅Nervous system
Smooth muscle to some degree

Questions And Answers Latest 2025
What system can influence the excitability of the skeletal muscle? -
correct answer ✅skeletal muscle completely depends on signaling
from the nervous system to work properly.
What other stimulus can the cardiac and smooth muscle respond
to? -
correct answer ✅Hormones and local stimuli.
What is the first process of muscle contraction? -
correct answer ✅When a protein called actin is pulled by a protein
called myosin.
Where does muscle contraction occur in skeletal and cardiac
muscles? -
correct answer ✅Striated muscle
Where is Ca ++ also required in contraction? -
correct answer ✅Ca++ also is required for the contraction of
smooth muscle, although its role is different: here Ca++ activates
enzymes, which in turn activate myosin heads.
, Anatomy Final Lecture Exam Ch 10
Questions And Answers Latest 2025
What do muscles require during the process of contracting? -
correct answer ✅All muscles require adenosine triphosphate (ATP)
to continue the process of contracting
What do muscles require when they relax? -
correct answer ✅When the Ca++ is removed and the actin-binding
sites are re-shielded.
How can a muscle return to its original length when relaxed? -
correct answer ✅Elasticity -- can recoil back to its original length
due to elastic fibers
What muscle quality is used during stretching or extension? -
correct answer ✅Extensibility
What allows the muscle tissue to pull on its attachments points and
shorten with force? -
correct answer ✅Contractility
How do the three muscles differ? -
correct answer ✅Include the microscopic organization of their
contractile proteins—actin and myosin.
