Muscles are made of thousands of small fibres woven together to form a type of elastic tissue. This tissue is what allows muscles to contract and move the body. There are three types of muscle tissue in vertebrates: skeletal muscle, cardiac muscle, and smooth muscle. Muscle tissue contains special contractile proteins called actin and myosin which interact to cause movement. Muscles are formed during embryonic development, in a process known as myogenesis.

Muscles are made of thousands of small fibres woven together
There are three types of muscle tissue in vertebrates: skeletal muscle, cardiac muscle, and smooth muscle. Skeletal muscles are part of your musculoskeletal system. They work with your bones, tendons and ligaments to support your weight and move you. Tendons attach skeletal muscles to bones all over your body. Skeletal muscles are voluntary — they move when you think about moving that part of your body.
During embryonic development, muscle is formed in a process known as myogenesis. Myoblasts (muscle progenitor cells) either remain in the somite to form muscles associated with the vertebral column or migrate out into the body to form all other muscles. Myoblast migration is preceded by the formation of connective tissue frameworks, usually formed from the somatic lateral plate mesoderm.

There are three types of muscle tissue in vertebrates: skeletal, cardiac, and smooth
Muscles are made of thousands of small fibres woven together. This soft tissue is elastic, like a rubber band, and allows for movement in the body. There are three types of muscle tissue in vertebrates: skeletal, cardiac, and smooth.
Skeletal muscles are part of the musculoskeletal system, working with bones, tendons and ligaments to support the body's weight and enable movement. Tendons attach skeletal muscles to bones all over the body. Skeletal muscles are voluntary, moving when you think about moving that part of the body.
Cardiac muscle is the type of muscle tissue found in the heart. The heart is a hardworking muscle that beats thousands of times a day to keep you alive.
Smooth muscle is the third type of muscle tissue. Smooth muscle is found in the walls of hollow organs such as the stomach, bladder, and blood vessels. Smooth muscle is involuntary, meaning it is not under conscious control. Smooth muscle is also found in the skin and eyes.

Skeletal muscles are voluntary and work with bones, tendons and ligaments to support your weight and move you
Skeletal muscles are created during embryonic development, in a process known as myogenesis. They are made of thousands of small fibres woven together, which stretch and press together to move your body. These fibres are a type of elastic tissue, similar to the material in a rubber band. Skeletal muscles are voluntary and work with bones, tendons and ligaments to support your weight and move you. Tendons attach skeletal muscles to bones all over your body.

Muscle tissue contains contractile proteins called actin and myosin which interact to cause movement
Muscles are made of thousands of small fibres woven together. This soft tissue is one of the four basic types of animal tissue. There are three types of muscle tissue in vertebrates: skeletal muscle, cardiac muscle, and smooth muscle.
Muscles are formed during embryonic development, in a process known as myogenesis. Skeletal muscle tissue is striated, consisting of elongated, multinucleate muscle cells called muscle fibres, and is responsible for movements of the body. During development, myoblasts (muscle progenitor cells) either remain in the somite to form muscles associated with the vertebral column or migrate out into the body to form all other muscles. Myoblast migration is preceded by the formation of connective tissue frameworks, usually formed from the somatic lateral plate mesoderm. Myoblasts follow chemical signals to the appropriate locations, where they fuse into elongate skeletal muscle cells.

Muscles are formed during embryonic development, in a process known as myogenesis
Muscles are made of thousands of small fibres woven together, which stretch and press together to move your body and organs. There are three types of muscle tissue in vertebrates: skeletal muscle, cardiac muscle, and smooth muscle. Skeletal muscles work with your bones, tendons and ligaments to support your weight and move you. Tendons attach skeletal muscles to bones all over your body.
Muscle tissue contains special contractile proteins called actin and myosin, which interact to cause movement. There are also two regulatory proteins, troponin and tropomyosin.
