Compare cardiac and skeletal muscle. Skeletal muscles are attached to bones all over the body which does not self-stimulate has a high speed of contraction and energy requirement and is responsible for performing voluntary muscular movements. The important differences between cardiac muscles and skeletal muscles have been discussed below. Difference Between Cardiac Muscle And Skeletal Muscle.
Cardiac muscles on the other hand are exclusively located along the walls of the heart. Skeletal muscles are important in body movement like sitting walking and lifting. Cardiac muscles function solely for pumping blood away from the heart towards the lungs and throughout the body.
Skeletal muscles can contract rapidly but get tired easily. On the other hand cardiac muscles can also. Cardiac muscles are found only in the heart.
Skeletal muscles are found attached to bones and skin. Smooth muscle cells line walls of the internal organs. Cardiac muscles are responsible for pumping blood throughout the body.
Relatively there is a huge difference in the length of a cardiac muscle fibre and a skeletal muscle fibre. Each cardiac fibre is up to 100µm whereas each skeletal fibre is between a few mm to a 10cm 4. A muscle fibre is also known as a muscle cell.
Most cells including cardiac muscle fibres cells have. Skeletal muscles are attached to bones cardiac muscles are found in the heart and smooth muscles are found in the stomach gut walls walls of the blood vessels and various internal organs of the body. Every muscle is different from the other in various aspects.
Cardiac muscles and skeletal muscles are also different in their shape. While the cardiac muscles are semi-spindle the skeletal muscles are cylindrical in shape. Another difference is that the cardiac muscles are short in comparison to skeletal muscles.
The skeletal muscles are attached to the bone through tendons. The skeletal muscles also contain myoblasts which form the fibers in the. Cardiac muscles are responsible to pump blood throughout the body while skeletal muscles are responsible for movement twitching holding and to perform work.
Cardiac muscles have long tertranic contraction while skeletal muscles have small twitch and long tertranic contraction. Cardiac muscles are elastic in nature while skeletal muscles are non elastic in nature. Cardiac muscle teams are elastic in nature whereas skeletal muscle teams are non elastic in nature.
Cardiac muscle diameter is 10 micro meter whereas skeletal muscle is 10 to 80 micro meter. Cardiac muscle has one or two nuclei whereas. Wherein the cardiac muscle cells have only one or 2 nuclei the skeleton muscle cells are multi-nucleated.
The cardiac muscle has a thick endomysium and many mitochondria occupying about 25 of the space whereas the skeleton muscle has actually a less dense endomysium and also fewer mitochondria occupying about 2 the the space.

Skeletal Smooth Cardiac Muscle Fibers Ziser 2001 Striated Muscle Cells Smooth Muscle Cells Cardiac Muscle Cells Voluntary Attached to bones or skin Very long cylindrical multnucleate cells Striated.
Packed with orderly arrangement of myofibrils Not self stimulating. Each fiber innervated by branch of somatic motor neuron as part of motor unit. Cardiac muscle is found in the heart walls helping to contract the heart and pump blood while skeletal muscles move bones and other structures.
Smooth muscle tissue changes shape to facilitate bodily functions and form organs like the stomach and bladder. The skeletal muscles are responsible for movements of the skeleton such as walking and moving arms. They also control facial tissues responsible for activities such as smiling or frowning.
The cardiac muscle controls blood flow in the heart while the smooth muscles move food and other substances along the gastrointestinal system. Cardiac muscle mitochondria help with energy production rhythmic capacity even at high force when needed. Research has shown that skeletal muscle mass grows in correlation to the force exerted.
These muscles are bigger than smooth and cardiac muscles as a. Difference between cardiac and skeletal. -influx of Ca2 from extracellular fluid triggers Ca2 release from sarcoplasmic reticulum SR -depolarization open slow Ca2 channels in sarcolemma allowing.
There are three types of muscle cells. Skeletal muscles cardiac muscles and smooth muscles. Skeletal muscles are muscles attached to the skeleton and are used for support and movement.
Attached to bones or some facial muscles to skin. Calls of the heart. Unitary muscle in the walls of hollow visceral organs other than the heart.
Multi unit muscle in the intrinsic eye muscles airways large arteries. Cell shape and appearance. Characteristics of cardiac muscles.
-timing of contraction determined by pacemaker cells. -contractions last longer than skeletal muscles. -no tetanic contractions possible.

Mention one difference between skeletal muscles and cardiac muscles. Skeletal muscles are governed by the somatic nervous system while the cardiac muscles are involuntary in nature. There are three main types of muscles namely skeletal muscle cardiac muscle and smooth muscle.
Skeletal muscles are attached to the skeletal system and smooth muscles are found in the walls of the hollow organs such as stomach bladder uterus etc.
