Contractile units of skeletal muscles are?
myofibrils
The contractile units of skeletal muscles are?
Myofibrils!
What is Smallest contractile units of a muscle?
Sarcomere
What is the contractile cell?
Contractile cells are the smooth muscle cells of the heart that... contract. They get their signal from the nodes within the heart, which spontaneously fire action potentials (because of leak channels).
Which is true concering muscles tissue?
Skeletal muscle are muscles that are attached the bones. These muscles are designed to stretch and help the body to move.
Are muscles always in a state of partial contaction?
A muscle fiber is made of many contractile units called sarcomeres.
Does muscle tissue contain contractile units made of collagen?
Collagen are fibres and are nonliving structure. They are very strong threads and do not contract.
What would be recruited later in the muscle stimulation when the contractile strength increases?
motor units with larger, less excitable neurons
How does skeletal muscle stimulation produce a sustained contraction?
By stimulating alternating motor units at a time.
Where are actin filaments found?
Actin and myosin are contractile proteins found within muscle fiber. If you look at a muscle fiber under a microscope it is made up of several repeating units called sarcomeres that run along the length of the muscle fiber. Proteins actin and myosin are found in the sarcomeres in different locations.
What is the difference between skeletal and other muscles?
Skeletal muscle is voluntary muscle that moves bones. It has long cells with striations and it is sometimes called striated muscle. Smooth muscle is slow moving, and is not controlled by the mind. It is also has the same functional units as skeletal muscle but it is harder to see. The last is cardiac muscle. This also has striations but they are short rather than long. This muscle is said to be autorhythmic. Each cell can beat on its' own and as a group, they beat together.
What does the cardiac muscle look like?
It depends on the type of muscle. We have three kinds, smooth, cardiac, and skeletal. The skeletal ones are called striated because they have bands that divide the smallest contracting units called sarcomeres. Skeletal muscles look much like long cords, cardiac are 'Y' or 'H' shaped, and smooth muscle are spindle shaped.
