The inflammation of the sheath surrounding a tendon is known as tenosynovitis. This condition often occurs due to repetitive motion, injury, or infection, leading to pain, swelling, and difficulty in movement of the affected tendon. Treatment typically involves rest, anti-inflammatory medications, and sometimes physical therapy. In chronic cases, more invasive interventions may be necessary.

What does tendonitis effect?
Tendonitis is an inflammation of the tendons. Tendonitis most commonly occurs with repetitive motion or strain on a specific tendon. For example: Tennis Elbow, also known as lateral epicondylitis, occurs more commonly in Tennis players because of the repetitive movement and strain on the lateral tendon over the bony prominence called the lateral epicondyle. As the tendon, which controls the extensor muscles of the forearm and wrist, moves over the bony prominence, irritation develops as the synovial sheath surrounding the tendon wears away resulting in tenosynovitis, as the wearing continues, the tendon itself becomes irritated and micro tears occur in the fibrous tendon resulting in inflammation of the tendon which is called tendonitis. It is difficult to differentiate between tenosynovitis and tendonitis, thus inflammation of the tendon at any stage is usually referred to as tendonitis. Bursitis can be commonly mistaken for tendonitis. Underneath the tendons is a fluid-filled sac called bursa, as the tendon rubs across the bursa, irritation and inflammation develop into bursitis. Bursitis is normally diagnosed by palpation of the bursa by pushing underneath the affected tendon. If the palpation causes pain, bursitis, if palpation of the tendon causes pain, tendonitis. Pain without stiffness or pain on stretching is normally associated with bursitis also.
What is the sheath of the Schwann Cell also called?
Surrounding the myelin sheath, there is a thin membrane called neurilemmal sheath. This is also called neurilemma or sheath of Schwann. This contains Schwann cells, which have flattened and elongated nuclei. The cytoplasm is thin and modified to form the thin sheath of neurilemma enclosing the myelin sheath. One nucleus is present in each internode of the axon. The nucleus is situated between myelin sheath adn neurilemma. At the node of Ranvier (where myelin sheath is absent), the neurilemma invaginates and runs up to axolemma in the form of a finger like process. In nonmyelinated nerve fiber, the neurilemma continuously surrounds axolemma. Neurilemma is absent in central nervous system. Neurilemma is necessary for the formation of myelin sheath (myelinogeneis).
What cyanobacteria contains a sheath?
Cyanobacteria in the genus Oscillatoria is known to contain a sheath. The sheath is a protective covering that surrounds the filamentous cells of Oscillatoria, providing structural support and protection.
What is the accumulation of fluid in a sac like cavity especially the testes?
The accumulation of fluid in a sac-like cavity, particularly in the testes, is known as a hydrocele. This condition occurs when fluid collects in the tunica vaginalis, the protective sheath surrounding the testes. Hydroceles can be congenital or acquired, often resulting from injury, infection, or inflammation. While typically painless and harmless, they may require treatment if they cause discomfort or swelling.
What is an inflammation of the tissue surrounding the elbow known as?
Inflammation of the tissue surrounding the elbow is known as elbow bursitis, or olecranon bursitis. This condition occurs when the bursa, a fluid-filled sac that cushions the joint, becomes inflamed due to injury, overuse, or infection. Symptoms typically include swelling, pain, and limited range of motion in the elbow. Treatment often involves rest, ice, and anti-inflammatory medications.
What causes the fingers to lock up?
Fingers can lock up due to a condition known as trigger finger, which occurs when the tendon that controls finger movement becomes inflamed or irritated. This inflammation can cause the tendon to catch on the surrounding sheath, leading to a locking or catching sensation. Other factors, such as repetitive hand movements, certain medical conditions like diabetes or rheumatoid arthritis, and age-related changes, can also contribute to this issue. In some cases, it may resolve on its own, while more severe cases might require medical intervention.
What is the term also known as tenalgia?
Tenodynia or tenontodynia (meaning pain in a tendon).

What is inflammation surrounding a joint?
Inflammation is the work of the immune system one form of joint inflamation that is also a chronic immune disorder is known as Rheumatoid arthritis.
What is weakest tendon in the body?
The weakest tendon in the human body isn't known. However, the Achilles tendon is viewed as the strongest in the body.
Name the long thin tendon that is a common source for tendon transplants?
The long thin tendon commonly used for tendon transplants is the flexor tendon from the hamstring muscle, known as the "semitendinosus" tendon.

One difference between bursae and tendon sheaths is that?
The difference between a bursa and a tendon is that a bursa is a synovial pocket insterted between a tendon and a bony prominance. It is not bound by a deep fascia or retinaculum. So from top to bottom a visual would be (tendon, synovial fluid, bone). A tendon synovial sheath, on the other hand, is bound by a deep facia or retinaculum and the synovial fluid almost completely surrounds the tendon with the exception of a small gap called the mesotendon.
