What qualities do cardiac and skeletal muscles share?
Cardiac and skeletal muscles are both striated muscles that contract in response to nerve impulses. They contain sarcomeres as their basic contractile unit and rely on the presence of calcium ions for muscle contraction. Additionally, both types of muscles are composed of muscle fibers that vary in size and length.
Name the 3 types of muscle?
smooth muscle, cardiac (say: kar-dee-ak) muscle, and skeletal (say: skel-uh-tul) muscleThere are three types of muscles. They are skeletal muscles which are voluntary, (diaphragm, muscles of limbs, other muscles that are associated with movement ), smooth muscles which are involuntary (tunica media of blood vessels, organs, others associated with sustaining life), and cardiac muscle, which is involuntary (only found in heart). Skeletal and cardiac muscles are also striated and have striations while smooth does not. The skeletal is also multinucleated while smooth and cardiac only has one nucleus per cell.Smooth, Cardiac, and Skeletal are the three muscle typesskeletal,smooth,cardiacskeletal, cardiac, and smooth muscleskeletal muscle, smooth muscle, and cardiac muscle.They are the cardiac, smooth and skeletal muscles.The three basic types of muscles are: voluntary muscles, cardiac muscles, and involuntary muscles.The three types of muscular types are Smooth muscle, Cardiac muscle, and Skeletal muscle.
What muscles are there?
There are three basic types of muscle: smooth, skeletal, and cardiac. Smooth muscles are part of organs like the intestines, skeletal muscles are connected to bones, and cardiac muscles makes up most of the heart.
What is the purpose of the muscle system?
Muscles allow the body to move. There is your basic answer. To give more information, you have three types of muscles. They are skeletal, smooth, and cardiac muscles. Your skeletal muscles are attached to your skeletal system as the name implies. The smooth muscles are all muscles that aren't skeletal muscles or cardiac muscles such as your diaphragm, which controls breathing, and stomach, which causes the stomach's contraction and expansion. Your cardiac muscles control the heart's beat. So as far as the purpose of the muscles system, is to keep you alive. Without it, you could not move, digest food, or circulate blood throughout your body.
What happens when summation occurs in cardiac muscle?
Basic muscle summation -an increase in the frequency with which a muscle is stimulated increases the strength of contraction. With increased stimuli to the heart if summation occurred the contractions would keep increasing.
What is the muscular structure?
The myofibril is the basic muscle cell, within which is the sarcomere, the basic unit of muscle contraction.
What are the tissues in skeletal muscle?
Skeletal muscle is made up of individual components known as muscle fibers. These fibers are formed from the fusion of developmental myoblasts (a type of embryonic progenitor cell that gives rise to a muscle cell). The myofibers (muscle fiber) are long, cylindrical, multinucleated cells composed of actin and myosinmyofibrils repeated as a sarcomere, the basic functional unit of the cell and responsible for skeletal muscle's striated appearance and forming the basic machinery necessary for muscle contraction. The term muscle refers to multiple bundles of muscle fibers held together by connective tissue. Wikipedia dude ...
What are the basic principles of somatic motor pathways?
The basic "principal" behind somatic motor pathways is a pathway from your "brain" or regions in or near the brain where nerve impluses travel from and go to skeletal muscle to cause a muscle contraction. (It's complicated, but doesn't get any more basic than this) -Jordan Bourne
Where is the sarcomere located?
The sarcomere is the basic unit of muscle structure and is located within the myofibrils of skeletal muscle cells. It runs from one Z disc to the next Z disc and is responsible for muscle contraction by sliding the actin and myosin filaments past each other.
What is the basic action of any muscle?
Contraction
What is the purpose of the muscled system?
Muscles allow the body to move. There is your basic answer. To give more information, you have three types of muscles. They are skeletal, smooth, and cardiac muscles. Your skeletal muscles are attached to your skeletal system as the name implies. The smooth muscles are all muscles that aren't skeletal muscles or cardiac muscles such as your diaphragm, which controls breathing, and stomach, which causes the stomach's contraction and expansion. Your cardiac muscles control the heart's beat. So as far as the purpose of the muscles system, is to keep you alive. Without it, you could not move, digest food, or circulate blood throughout your body.
In the skeletal muscle what is a Z-disk or Z line?
The Z-disk, also known as the Z line, is a structure in skeletal muscle that separates one sarcomere (the basic contractile unit of muscle) from the next. It serves as an anchor for actin filaments and helps to transmit force generated during muscle contraction. The Z-disk also plays a role in maintaining the alignment of myofibrils within the muscle cell.
