Muscles are made of thousands of small fibres woven together. They are attached to bones by tendons, which are cords made of tough tissue. Tendons work as special connector pieces between bone and muscle, allowing muscles to pull on bones and support joints.

What You'll Learn
- Tendons are cord-like tissues that attach skeletal muscles to bones
- Skeletal muscles work with bones to give the body power and strength

- Ligaments are long, fibrous straps that fasten bones together
Tendons are cord-like tissues that attach skeletal muscles to bones
Skeletal muscles are attached to bones with the help of tendons. Tendons are cord-like tissues that attach skeletal muscles to bones all over the body. They work as special connector pieces between bone and muscle. They are attached so well that when you contract one of your muscles, the tendon and bone move along with it.
Tendons are made of tough tissue. They are bands of fibrous tissue that connect muscles to bones. They are attached to one end of a bone and stretch all the way across a joint (the place where two bones meet) and then attach again to another bone.
Skeletal muscles are called striated because they are made up of fibres that have horizontal stripes when viewed under a microscope. These muscles help hold the skeleton together, give the body shape, and help it with everyday movements. They can contract (shorten or tighten) quickly and powerfully, but they tire easily.

Muscles are made of thousands of small fibres woven together. These fibres stretching and pressing together is what moves your organs or body. They run in all directions and work together to move you. Muscles can pull on bones, but they can't push them back to their original position, so they work in pairs of flexors and extensors. The extensor muscle relaxes and stretches as the flexor muscle contracts to bend the joint. The flexor then relaxes and the extensor contracts to straighten the limb at the same joint.

Muscles work in pairs of flexors and extensors to bend and straighten joints
Skeletal muscles are attached by cord-like tendons to bones in the legs, arms, and face. They are called striated because they are made up of fibres that have horizontal stripes when viewed under a microscope. These muscles help hold the skeleton together, give the body shape, and help with everyday movements. They can contract (shorten or tighten) quickly and powerfully, but they tire easily.
The extensor muscle relaxes and stretches as the flexor muscle contracts to bend the joint. The flexor then relaxes and the extensor contracts to straighten the limb at the same joint. Muscles get their signals to contract and relax from the brain.

Smooth, or involuntary, muscles are controlled by the nervous system
Skeletal muscles are attached to bones with the help of tendons, which are cord-like pieces of tough tissue. Tendons work as special connectors between bone and muscle, allowing the bone to move when the muscle contracts.
There are three types of muscle tissue in the body: skeletal, smooth, and cardiac. Smooth muscles are involuntary muscles that are controlled by the nervous system. They are also known as involuntary muscles because we can't consciously control them. Instead, the nervous system uses hormones, neurotransmitters, and other receptors to control smooth muscle spontaneously. Smooth muscle is used by the nervous system to tightly regulate many of the body's subsystems for life with no thought from the user. For example, a person does not need to think about their blood pressure for it to adapt to increasing oxygen demands from exercise. Smooth muscle also plays an important role in the disease process throughout the body. For instance, the use of bronchodilators to relax airway smooth muscle is an important and life-saving treatment in asthmatics.
The autonomic nervous system allows for tight unconscious control of critical body functions such as digestion, respiratory rate, urination, heart rate, and blood pressure. Due to autonomic control regulatory effects of smooth muscle, every surgery will be impacted by its overall function. Monitoring a patient's vital signs during surgery is paramount to a successful procedure and the stressors of surgery can have a vast impact on the autonomic nervous system.

Muscles are held together by tendons, which are cord-like bands of fibrous tissue that connect muscles to bones.
Tendons are made of tough tissue and work as special connector pieces between bone and muscle. They are attached so well that when you contract one of your muscles, the tendon and bone move along with it.
There are three types of muscle tissue in the body: skeletal, smooth and cardiac. Skeletal muscles are attached to bones by tendons and are under our conscious control. Smooth muscles are involuntary and are controlled by the nervous system. Cardiac muscles are found in the heart.
