This ability to stretch and still maintain contractility is important in organs like the intestines and urinary bladder. So they are also called as smooth muscles. Thus they are also called as smooth muscles. They are found in hollow organs and have a smooth surface. Their contractile unit is sarcomere which is actually the area between two adjacent Z lines. These muscles contain more than one nucleus and, depending upon the part of the body, can be up to 30 centimeters in length. Striated muscles are under the conscious control of the animal while nonstriated muscles are not under conscious control.

It is compulsive for biology students to know the major differences between these two types of muscles. These are those types of muscles in which muscle fibers do not exhibit cross striations. Striated muscles are attached to the skeleton via tendons. They are not attached to bones. In striated type, sarcoplasmic reticulum is developed while in the nonstriated muscles, it is not well developed.

They are those types of muscles in which muscle fibers show cross striations. Striated muscle fibers are giant, polynucleated cells ranging from 10 to 100 μ in diameter. In these bands actin and myosin filaments are present, this forms a complete unit of the sarcomere. Sarcomeres are present in the striated muscles while not present in the nonstriated muscles. skeletal muscle, striated muscle - a muscle that is connected at either or both ends to a bone and so move parts of the skeleton; a muscle that is characterized by transverse stripes pronator - a muscle that produces or assists in pronation The muscle tissue tissue is an important tissue in locomotion and movement.According to the physiological function and location of the muscle, muscles are divided into three types, namely striated, non – striated and cardiac muscle. A typical muscle has a central portion called the belly and two or more attachment ends with tendons; the more stationary of the attachments is called the muscle's origin, while the more movable attachment is called the muscle's insertion. Skeletal muscle is voluntary and striated, cardiac muscle is involuntary and striated, and smooth muscle is involuntary and non-striated.

It is a white colored elongated band. Non-striated muscles are uninucleated, do not have proper sarcoplasmic reticulum and have less concentration of mitochondria in it. Striated muscles are attached to bone via tendons; these muscles are involved in the voluntary movement because they are under the control of our will, due to this striated muscles are also called voluntary muscles. Striated muscles exhibit cross-striations of muscle fibers while nonstriated muscles do not exhibit the cross striations.

Their examples can be given as bicep muscles, tricep muscles, rectus muscles of abdomen, quadriceps, hamstring muscles of thigh and muscles of the shoulder girdle, etc. This muscle is only found within the heart. Smooth muscle myocytes are spindle shaped with a single centrally located nucleus. (b) Smooth muscle cells have a single nucleus and no visible striations. They are also named as skeletal muscles because they are attached with bones via tendons. They have sarcomeres which are their contractile unit. Muscle tissues are concerned with the motion of the organisms and movements of other body parts. They exhibit a very smooth surface, and that is the reason for naming them smooth muscles. It also contains many mitochondria and stores large amount of glycogen in it. The ends of muscle fibers are intertwined with tendon fibers, and through this combination muscular tension is transmitted to the skeletal bones. tid) adjective Void of striations; without stripes, as muscle fibers.

Non-striated muscle cells, pigment cells, and blood capillaries are abundantly present in the connective tissue external to the lining epithelium of the lung-cavities. It contains less number of mitochondria as compared to striated muscles and stores small amount of glycogen in it. Unlike the striated muscles, the smooth muscle tissues contract at a slower pace automatically. Muscles are classified histologically into striated muscles and non-striated muscles based on the structural characteristic called “striations” which is due to the arrangement of the muscle fibre’s actin and myosin filaments. Smooth muscle cells do not contain sarcomeres and are, therefore, non-striated muscle cells. This causes the muscle tissue to be striated, or have a striped appearance. Muscle fiber cells have a single nucleus in a cell. Voluntary refers to whether the muscle is under conscious control, striation refers to the presence of visible banding within myocytes which occurs due to organization of myofibrils to produce a constant direction of tension. Their examples can be given as muscles of the urinary bladder, small intestine, muscles of the large intestine, muscles of stomach and gall bladder, etc. In non-striated muscles, proper sarcomere is not present due to which it gives an irregular shape under a microscope. The shape of muscle fibers of striated muscles is spindle shape, and they exhibit blunt ends. They are called involuntary muscles due to this property. These smooth muscles consist of a non-striated, slender type of tapering fibres. It is divided into two subgroups; the single-unit (unitary) and ... smooth muscle tissue tends to demonstrate greater elasticity and function within a larger length-tension curve than striated muscle.

These are those types of muscles in which muscle fibers do not show cross striations. Striated Muscle Fibres: Non- Striated. The key difference between striated muscles and nonstriated muscles is that striated muscle fibers exhibit cross striations while nonstriated muscle fibers do not show cross striations. These band are created by the highly organized sarcomeres. Non-striated muscles are completely involuntary. The striated muscles that are forming in the head anlage receive their innervation from motor neurons that are derived from the basal plate (Figs. Look it up now! 1.
