What else can I help you with?
Do skeletal muscle fibers contain sarcomeres whereas smooth muscle fibers do not?
Yes, skeletal muscle fibers contain sarcomeres, which are the repeating units responsible for muscle contractions. In contrast, smooth muscle fibers do not have sarcomeres in the same organized structure but still have contractile proteins.
What are the differences between isometric, concentric, and eccentric muscle contractions?
Isometric muscle contractions happen when the muscle stays the same length, concentric contractions occur when the muscle shortens, and eccentric contractions occur when the muscle lengthens.
What would happen if the length of the absolute refractory period in cardiac muscle cells was the same as it is for skeletal muscle cells?
tetanic contractions might occur, which would stop the hearts pumping action
What is the relationship between skeletal muscle and voluntary muscle?
They are one and the same.
How are skeletal and cardiac muscle the same?
They are both striated.
Who has more nuclei per cell skeletal muscle or cardiac muscle?
which has more nuclei per cell skeletal muscle or cardiac muscle? I guess that they both have the same number of nuclei.
How does the appearance of smooth muscle differ from that of skeletal muscle when viewed with a microscope?
i need the same answer...-.-
How is skeletal muscle adapted for its role in the body?
Skeletal muscle is striated and composed of long, multinucleated fibers that can contract and relax to generate movement. It contains numerous mitochondria to produce energy for muscle contractions, and is innervated by motor neurons to enable voluntary control. Additionally, muscle fibers have a high density of myofibrils, which contain actin and myosin filaments that slide past each other to facilitate muscle contraction.
What head muscle helps you bite a carrot stick?
The same muscles that allow you to smile. Your jaw muscles of course!
Is a skeletal muscle the same as a striated muscle?
Yes, skeletal muscles are voluntary, meaning they can be intentionally controlled. This distinguishes them from the cardiac muscle (heart) and smooth muscles, which are involuntary.
What sport uses isokinetic muscle contractions?
isokinetic muscle contractions are muscle contractions at a constant rate or speed. Obviously all sports vary at least a little in each muscle movement. but for example, rowing could be one, long distance running, cycling, jump rope, or other sports in which the range of motion is generally the same with each play/repetition.
Where does glycolysis occur in skeletal muscle?
Same place as everywhere else in the body. The cytoplasm.
