Rheumatoid nodules are firm lumps that develop under the skin. They are a symptom that is unique to rheumatoid arthritis and usually occur near joints affected by the condition. About a quarter of people with rheumatoid arthritis develop rheumatoid nodules.

Synovial Joints. Synovial joints allow for smooth movements between the adjacent bones. The joint is surrounded by an articular capsule that defines a joint cavity filled with synovial fluid. The articulating surfaces of the bones are covered by a thin layer of articular cartilage.

Ligaments are bands of fibrous tissue that connect bones to bones at joints. A strain is also a stretch or tear, but it happens in a muscle or a tendon.

The various muscle fibers start to stick to each other and become adhered. This new hard and lumpy feeling is a muscle 'knot'. Muscle 'knots' are incredibly common but common doesn't mean they are normal or harmless. Chronic stress on our muscles creates micro-tearing of muscle tissue, which creates scar tissue.

A fibrous joint is where the adjacent bones are united by fibrous connective tissue. At a cartilaginous joint, the bones are joined by hyaline cartilage or fibrocartilage. ... Synovial joints allow for free movement between the bones and are the most common joints of the body.

Fibrous joints are where adjacent bones are strongly united by fibrous connective tissue. The gap filled by connective tissue may be narrow or wide. The three types of fibrous joints are sutures, gomphoses, and syndesmoses. A suture is the narrow fibrous joint that unites most bones of the skull.

Surgical knots (ligatures) are the knots used to bind suture materials together while binding tissue in surgery. They are used in medical and veterinary settings.

Dupuytren's contracture is a condition that causes nodules, or knots, to form underneath the skin of your fingers and palms. It can cause your fingers to become stuck in place. It most commonly affects the ring and little fingers. However, it can involve any finger.

A muscle knot, also called a trigger point, is an area of tense muscle. It develops when muscle fibers tighten and contract, even when the muscle isn't moving. Your neck is especially prone to muscle knots.

These lumps are called Heberden's nodes (when around the more distant knuckle) or Bouchard's nodes (when around the closer knuckle) and actually consist of bone spurs around the joints. These knuckles often become enlarged, swollen, and stiff.

Knots are comprised of tense muscle fibers. "Muscle knots are actually hyperirritable spots in muscle or fascial tissue [bands or sheets of connective tissue] known as myofascial trigger points," says Charleston. Trigger points typically fall into one of two categories: Active.

Synovial joints are the most movable type of joint found in the human body. Joints are formed where bones come together. ... Pivot joints are found in your neck vertebrae, while hinge joints are located in your elbows, fingers, and knees. Saddle and plane joints are found in your hands.

If you have a knot in your neck, it means some of the muscle fibers in your neck are continually contracting. This can cause neck pain that feels dull, achy, or sharp. The pain might occur at the knot or in a nearby area, like your shoulder or arm.

Fibrous joints contain fibrous connective tissue and cannot move; fibrous joints include sutures, syndesmoses, and gomphoses. Cartilaginous joints contain cartilage and allow very little movement; there are two types of cartilaginous joints: synchondroses and symphyses.
