Costochondritis, also known as chest wall pain syndrome or costosternal syndrome, is a benign inflammation of the upper costochondral (rib to cartilage) and sternocostal (cartilage to sternum) joints. 90% of patients are affected in multiple ribs on a single side, typically at the 2nd to 5th ribs. [1]
The intercostal nerves are part of the somatic nervous system, and arise from the anterior rami of the thoracic spinal nerves from T1 to T11. [1] [2] The intercostal nerves are distributed chiefly to the thoracic pleura and abdominal peritoneum, and differ from the anterior rami of the other spinal nerves in that each pursues an independent course without plexus formation.
In costochondritis and Tietze syndrome, inflammation of the costal cartilage occurs. [4] This is a common cause of chest pain. [5] Severe trauma may lead to fracture of the costal cartilage. [6] Such injuries often go unnoticed during x-ray scans, but can be diagnosed with CT scans. [6]

It also flexes the neck. [4] When both sides of the muscle act together, it flexes the neck and extends the head. When one side acts alone, it causes the head to rotate to the opposite side and flexes laterally to the same side (ipsilaterally). It also acts as an accessory muscle of respiration, along with the scalene muscles of the neck.
Other ligaments are made mostly of viscoelastic collagen fibers, a material two orders of magnitude stiffer, which cannot retain their original shape when extended past a certain point or for a prolonged period of time. [6] [7] Structurally, the nuchal ligament is formed with the association of both elastin proteins as well as type III collagen ...
Costochondritis is considered a more common condition and is not associated with any swelling to the affected joints, which is the defining distinction between the two. [ 2 ] [ 5 ] Tietze syndrome commonly affects the 2nd or 3rd rib and typically occurs among a younger age group, [ 2 ] while costochondritis affects the 2nd to 5th ribs and has ...
It promotes stabilization of head position by innervating the neck muscles, which helps with head coordination and eye movement. Its function is similar to that of the tectospinal tract . The lateral vestibulospinal tract provides excitatory signals to interneurons , which relay the signal to the motor neurons in antigravity muscles. [ 6 ]
