Structural characteristics of muscle tissue

Physiological differences from cardiac and skeletal muscle tissue. The myofibrils with transverse striation.

For example if you would swallow a large bolus of food the smooth muscle in your esophagus must be able to stretch and allow it to pass or it would become painfully stuck.

Structural characteristics of muscle tissue. Muscular tissue is a specialized tissue in animals which applies forces to different parts of the body by contraction. It is made up of thin and elongated cells called muscle fibers. It controls the movement of an organism.

The cytoplasm in the muscle fibers is called sarcoplasm. It contains a network of membrane called the sarcoplasmic reticulum. Matrix is nearly absent in muscular tissue.

Themuscle cells are elongated and fibre-like. The fibres are spindle shaped. The fibres are known as myofibril.

The cytoplasm of muscle cell may have one or more nuclei. The cell membrane of the muscle cell is known as sarcolemma. The myofibrils with transverse striation.

Muscle tissue is characterized by properties that allow movement. Muscle cells are excitable. They respond to a stimulus.

They are contractile meaning they can shorten and generate a pulling force. When attached between two movable objects such as two bones contraction of the muscles cause the bones to. Muscle tissue Muscle tissue is both extensible and elastic in other words it can be stretched and returned to its original size and shape.

The cells of muscle tissue are unique in that they are contractile or capable of contraction. This contraction is a result of sliding actin and myosin filaments. Muscle tissue is easily distinguishable by its highly organized bundles of cells.

Muscle tissue is characterized by properties that allow movement. Muscle cells are excitable. They respond to a stimulus.

They are contractile meaning they can shorten and generate a pulling force. When attached between two movable objects in other words bones contractions of. Muscle is a soft tissue that is highly specialized for the production of tension which results in the generation of force.

Muscle cells or myocytes contain myofibrils comprised of actin and myosin myofilaments which slide past each other producing tension that changes the shape of the myocyte. Cardiac muscle tissue is one of the three types of muscle in your body. Its only found in your heart where its involved in coordinated contractions that keep your heart beating.

Skeletal muscle has four major functional characteristics. Contractility excitability extensibility and elasticity. 1Contractility kon-trak-til i-te is the ability of skeletal muscle to shorten with force.

When skeletal muscles contract they cause the structures to which they are attached to move. Forms tubular network around each myofibril. On either side of t tubules.

Forms a triad myofibrils lie sandwiched between pair of cisternae. Contain high concentration of Ca. Muscle cells have 4 primary properties.

Muscle tissue has the ability to contract and shorten. Muscles can actively shorten but they cannot actively lengthen themselves. They must rely on their antagonist muscles or another external forces such as gravity to help them lengthen.

This is the characteristic of muscle tissue that describes the muscles. Muscle is fibrous tissue that contracts to produce movement. There are three types of muscle tissue in the body.

Skeletal smooth and cardiac. Muscle tissue is attached to the bones through tendons which are highly elastic portions of connective tissue. Many muscles may seem to control a single appendage but in reality each one only controls one small aspect of movement.

Skeletal muscle tissue can be controlled voluntarily by the somatic nervous system. Physiological differences from cardiac and skeletal muscle tissue. -Contraction in a smooth muscle fiber starts more slowly and lasts much longer than skeletal muscle fiber contraction.

-smooth muscle can both shorten and stretch to a greater extent than the other muscle types. Contraction of smooth muscle. Cardiac muscle tissue is only found in the heart.

Highly coordinated contractions of cardiac muscle pump blood into the vessels of the circulatory system. Similar to skeletal muscle cardiac muscle is striated and organized into sarcomeres possessing the same banding organization as skeletal muscle. Characteristics of muscles- Muscular System.

All muscles share certain characteristics such as the ability to stretch called extensibility. For example if you would swallow a large bolus of food the smooth muscle in your esophagus must be able to stretch and allow it to pass or it would become painfully stuck. Nervous or the nerve tissue is the main tissue of our nervous system.

It monitors and regulates the functions of the body. Nervous tissue consists of two cells. Nerve cells or neurons and glial cells which helps transmit nerve impulses and also provides nutrients to neurons.

Brain Spinal Cord and nerves are composed of nervous tissue they are specialized for being stimulated to transmit stimulus. The musculoskeletal system comprises one of the major tissueorgan systems in the body. The three main types of muscle tissue are skeletal cardiac and smooth muscle groups123 Skeletal muscle attaches to the bone by tendons and together they produce all the movements of the body.

The skeletal muscle fibers are crossed with a regular pattern of fine red and white lines giving the. Be able to name and to identify the three types of muscle at the light and electron microscope levels including distinctive features of each such as the intercalated discs of cardiac muscle. Be able to describe and understand the structural basis of muscle striation at the light microscope and EM levels and the molecular level.

Skeletal muscle structure and function. The muscle system is responsible for movement of the human body posture movement of substances inside the body andfor the generation of body heat. There are approximately 700 known and named muscles and on top of that muscle tissue is also found inside of the heart digestive organs and blood vessels.

Connective tissue CT is one of the four basic types of animal tissue along with epithelial tissue muscle tissue and nervous tissue. The amount of matrix is more in connective tissue but the number of cells is comparatively less. Matrix may be jelly like soft or hard and fragile.
