Human anatomy exam test queries
and answers graded A+
What are the 3 types of muscles? - ANS✅✅skeletal, cardiac, smooth
*?* muscle pulls on the bones of the skeleton - ANS✅✅skeletal
*?* muscle makes up most muscle of the body - ANS✅✅skeletal
*?* muscle is located only in the heart and pushes blood through circulatory system -
ANS✅✅cardiac
*Cardiac muscle* is the same thing as *?* - ANS✅✅myocardium
*?* muscle pushes fluids and solids along the digestive tract and regulates the diameters of small
arteries - ANS✅✅smooth
Where is smooth muscle located? - ANS✅✅lining digestive tract, arteries, etc.
*?* muscle is striated and voluntary - ANS✅✅skeletal
*?* muscle is striated, y-shaped, involuntary, and has intercalated discs - ANS✅✅cardiac
*?* muscle is NOT striated and is involuntary - ANS✅✅smooth
What are some properties of skeletal muscle? - ANS✅✅-contractility (muscles can shorten)
-excitability (very responsive to stimuli)
-extensibility (can increase in length)
-elasticity (able to return to original length)
What are some functions of skeletal muscle? - ANS✅✅-produce movement
,-maintain posture
-support
-generate heat
-storage of movement and materials
What is an example of a skeletal muscle that stores and moves materials? - ANS✅✅external anal
sphincter
Skeletal muscles are mostly *?*, but also contain *?*, *nerves, and blood vessels* -
ANS✅✅skeletal muscle tissue, connective tissue
*T/F*
Skeletal muscle is an organ. - ANS✅✅True
Muscle is composed of multiple *fascicles* which are composed of individual *?* - ANS✅✅muscle
fibers
A bundle of *muscle fibers makes a *?*, a bundle of those makes a ?* - ANS✅✅fascicle, muscle
What are the connective tissue membranes from superficial to deep? - ANS✅✅deep fascia,
epimysium, perimysium, endomysium
*?* is a sheet of connective tissue that surrounds individual muscles, as well as *groups* of muscles
with same action - ANS✅✅deep fascia
*?* is a membrane that surrounds entire "muscle" and separates *individual* muscles -
ANS✅✅epimysium
*?* surrounds each fascicle and divides skeletal muscle into compartments - ANS✅✅perimysium
*?* surrounds the muscle fibers within a fascicle - ANS✅✅endomysium
*?* is the contractile portion in muscle fiber - ANS✅✅myofibril
, There are hundreds of thousands of *?* in each skeletal muscle fiber - ANS✅✅myofibrils
Along the length of a myofibril there are repeating segments called *?* - ANS✅✅sarcomeres
*?* is the basic functional unit of a skeletal muscle - ANS✅✅sarcomere
Contraction of the *?* is what contracts the muscle (and shortens the *?*) - ANS✅✅sarcomere
A sarcomere extends from *?* to *?* - ANS✅✅z disk
There can be as many as *?* sarcomeres per myofibril - ANS✅✅10,000
The center of the *sarcomere* is the *?* - ANS✅✅M line
The relationship between *?* and *?* gives the appearance of stripes on the muscle -
ANS✅✅actin, myosin
The thick filaments on a sarcomere are called *?* - ANS✅✅myosin
The thin filaments on a sarcomere are called *?* - ANS✅✅actin
*?* are thick and thin filaments within a sarcomere - ANS✅✅myofilaments
The striations you see in skeletal muscle come from the differences in the *?* and *?* of the
filaments - ANS✅✅density and size
Dark bands on sarcomeres are *?* - ANS✅✅thick filaments
Light bands on sarcomeres are *?* - ANS✅✅thin filaments
