1, ligament

Ligament consists of dense connective tissue. The ligament outside the joint capsule is located around the joint cavity. The ligament in the joint capsule is located in the joint cavity. The part located on the joint capsule, that is, the thickened fibrous layer of the joint capsule, is called the joint capsule ligament.

The other ligament is formed by peritoneal folds, which is formed by migration between peritoneal wall layer and visceral layer or between peritoneal visceral layer and visceral layer. Some of these ligaments are formed by single peritoneum, and some are formed by double peritoneum.

2. Tendon

Tendons, mostly invisible, are attached to bones, which can contract muscles, move joints and fix them. At the beginning of life, the baby's body is particularly soft, because their tendons are very soft, and the soft tendons make the meridians unobstructed, full of qi and blood, showing vitality.

Extended data:

In our spoken language, tendons generally refer to four completely different things anatomically:

"tendon" is not an independent concept in modern anatomy. Although there is also the word "fascia", it is only borrowed from the word "tendon" in our spoken language.

Traditional Chinese medicine believes that the human body has 485 tendons, which is a general generalization without understanding anatomical knowledge. In fact, it includes muscles, tendons, ligaments, fascia, tendon sheath, synovial sac, joint capsule, nerves and blood vessels, and even articular cartilage and glenoid margin in modern medicine.

First: human muscles, specifically skeletal muscles, because its most basic function is to stretch and pull joints to make various actions. Muscles need regular activities, that is, stretching, to maintain flexibility and elasticity. Acrobats and gymnasts can bend the body that ordinary people can't bend, mainly because training can prolong the length of muscles.

Second, tendon is a kind of cord-like or membrane-like dense connective tissue connecting bone and muscle, which is composed of parallel dense collagen fiber bundles. It is white, firm and has no contraction function, and its tensile strength is 1 12-233 times that of muscle. For example, a person can touch a "big tendon" in the heel, which is the achilles tendon. Another example is the back of our hand. There are five extensor tendons corresponding to five fingers, which is very powerful.

Third: Ligament, which exists in human joints, is a dense fiber connective tissue bundle connecting bones, and its function is to strengthen the stability of joints and limit their excessive movement. Improper exercise can lead to muscle and ligament strain.

Fourth, the swelling of superficial veins can be seen when blood pressure or pressure rises, which is more obvious in the neck.
