Ventral ramus of lower thoracic nerve

The **ventral ramus of a lower thoracic nerve** is an anterior branch of a spinal nerve emerging from the thoracic spinal cord (typically T7–T12), after the nerve exits the intervertebral foramen[1][3][5]. Each ventral ramus supplies the muscles and skin of the anterolateral trunk and, in the lower thoracic region, continues as an intercostal nerve supplying the chest and abdominal wall[1][2][4][5]. These nerves carry both motor and sensory fibers, as well as some autonomic fibers, but are considered anatomical structures rather than molecular therapeutic targets[1][3]. Their clinical significance relates to their involvement in nerve blocks, potential for neuralgia, and risk of injury in thoracic or abdominal procedures[4][5]. **Notes on correctness:** The "ventral rami of lower thoracic nerves" are not molecular targets such as receptors, enzymes, or transporters, but rather gross anatomical structures—specifically, branches of mixed spinal nerves in the peripheral nervous system[1][3][5]. As such, they do not have known drug interactions, molecular classifications, canonical abbreviations, or established biomarker roles as would a molecular therapeutic target. **Summary judgment:** This entry is anatomically correct, but not a molecular or pharmacological target, and should be marked as "incorrect" for structured drug target databases.
