Intercostal nerves
Intercostal Nerves
The Intercostal Nerves (/ɪntərˈkɒstəl nɜːrvz/), from the Latin inter (between) and costa (rib), are part of the peripheral nervous system that run between the ribs and are responsible for conveying sensory information from the thoracic wall and abdominal wall to the central nervous system.
Anatomy
The Intercostal Nerves originate from the anterior rami of the thoracic spinal nerves from T1 to T11. They are grouped into three main categories: the typical intercostal nerves (T3-T6), the upper intercostal nerves (T1-T2), and the lower intercostal nerves (T7-T11).
Function
The primary function of the Intercostal Nerves is to provide sensory innervation to the skin and muscles of the thoracic and abdominal wall. They also play a role in the motor innervation of the intercostal muscles, abdominal muscles, and subcostal muscles.
Clinical Significance
Damage or irritation to the Intercostal Nerves can result in conditions such as Intercostal neuralgia, a condition characterized by pain along the course of the nerve. Treatment options for this condition include medications, nerve blocks, and in severe cases, surgery.
