Abstract:
Ganglion cysts arising from tendons are uncommon lesions with an unknown cause. We present a case report of a 38-year-old female was diagnosed with an intra-tendinous ganglion cyst of the peroneus longus. She complained of right ankle swelling for 1 year and associated with pain. MRI revealed a peroneus longus intra-tendinous ganglion below the lateral malleolus with a thin wall. The ganglion cyst was surgically excised while the structure of the peroneus longus tendon was preserved. The clinical and functional outcomes were satisfactory after 1 year without recurrence.

Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...
Somatic Spinal Reflexes
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...
Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...
