The individual has no control over their contraction and relaxation. Skeletal muscles however are voluntary muscles. One has complete control over their contraction and relaxation.

Smooth muscles contract more slowly. The rate of contraction of skeletal muscles is fast but they can tire easily. What is the difference between Smooth Muscle and Skeletal Muscle.

Skeletal muscles are striated but not the smooth muscles. Skeletal muscles are voluntarily controlled while smooth muscles are involuntarily controlled. Skeletal muscle cells are multi nucleated but smooth muscle cells have a single nucleus in each.

Smooth muscle is made of single spindle-shaped cells. It gets its name because no striations are visible in them. Nonetheless each smooth muscle cell contains thick myosin and thin actin filaments that slide against each other to produce contraction of the cell.

The thick and thin filaments are anchored near the plasma membrane with the help of intermediate filaments. Produces movement maintains posture stabilises joints and generates heat Smooth muscle. Found in the walls of hollow organs Cardiac muscle.

Exists only in your heart. Skeletal muscles are attached to the bones. Smooth muscles line up the visceral organs viz.

Intestinesblood vesselspupils etc therefore also known as visceral muscles Skeletal muscles perform voluntary actions. Smooth muscles are responsible for involuntary reflexes and actions. Skeletal muscles are attached to bones and allow voluntary movement of the body.

Smooth muscles which generate involuntary movement form part of the walls of the esophagus stomach intestines bronchi uterus urethra bladder and blood vessels among other portions of the body. Skeletal muscles perform voluntary actions while smooth muscles perform involuntary actions. Skeletal muscles involved in movement of the body.

Smooth muscles are responsible for proper functioning of organs. 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. During skeletal muscle contraction a special type of protein called troponin plays an integral part while troponin is not involved with smooth muscle contraction.

Smooth muscle differs from skeletal muscle in a variety of ways perhaps the most important being its ability to be contracted and controlled involuntarily. The nervous system can use smooth muscle to tightly regulate many of the bodys subsystems for life with no thought from the user. Skeletal muscles comprise very long cylindrical multinucleated cells.

Smooth muscles comprise single tapering single nucleated cells. Cardiac muscle cells are striated with many myofibrils in orderly arrangements. Skeletal muscle cells are striated with orderly arranged myofibrils.

Descriptions and examples of the three types of muscles in the human body. Three Types of Muscles Found in the Human Body. Skeletal muscles that move voluntarily Smooth involuntary muscles in organs Cardiac only found in the heart.

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.

Smooth muscle is a type of muscle tissue that is utilized by different systems for the application of pressure to organs and vessels. It is an involuntary muscle which shows no cross stripes even when examined under a microscope. A smooth muscle is composed of cells that are narrow and spindle-shaped with a single nucleus that is located centrally.

Endomysium Epimysium Fascicle Muscle fiber. There are two major classifications of muscle. Skeletal as well as cardiac muscle fall under the category of striated.

Muscles are metabolically dynamic tissues and receive plentiful blood flowAll muscles can be excited in that they respond to stimuli outside or inside the body. Both skeletal and smooth muscle contain actin and myosin filaments which form cross-bridges in order for the muscle to contract. Both also contain a sarcoplasmic reticulum -.

Smooth muscle cells are more diverse than are those of skeletal or cardiac muscle. In some organs smooth mus-cle is innervated in a manner similar to skeletal muscle in that each smooth muscle cell receives synaptic input. However a difference is that a smooth muscle cell may receive input from more than one neuron.

Calcium is the most vital substance in the process of skeletal muscle contraction. Neurotransmitters Acetylcholine or Norepinephrine play important role in smooth muscle contraction. Types of Skeletal Muscles are Red and White.

Types of Smooth Muscles are Single-unit Multi-unit eg. They contain actin and myosin filaments. Smooth muscles have a much stronger ability to contract than skeletal muscles and are able to maintain contraction longer.

There are two types of smooth muscles. Visceral smooth muscle - all cells work together at the same time as one unit. Multi-unit smooth muscle - cells can act and function independently of the others.

Cardiac Smooth and Skeletal Muscle The basic contractile process is the same in cardiac smooth and skeletal muscle with movement produced by the action of the myofilaments actin and myosin. However because the requirements in terms of speed and force of contraction are different the structure of cardiac and smooth are slightly different than skeletal muscle. Smooth muscle tissue has a different structure compared to cardiac and skeletal muscle tissue.

Smooth muscle does not contain sarcomeres the organized contractile units that are found in cardiac and skeletal muscle tissue nor does it contain the myofibrils which are those rod-like structures made up of the repeating segments of sarcomeres.
