Musculus iliocostalis cervicis
This is the cranial extension of the iliocostalis. It originates from the cranial borders of the first few ribs and inserts on the transverse processes of the caudal cervical vertebrae. It extends and laterally flexes the cervicothoracic junction. Innervation is via the dorsal branches of the cervical and upper thoracic spinal nerves. It contributes to fine control and stabilization at the base of the neck.
Origin: Cranial borders of ribs 1-4
Insertion: Transverse processes of the last few cervical vertebrae
Action: Extends and laterally flexes the cervicothoracic junction
Innervation: Dorsal branches of cervical and upper thoracic spinal nerves
Rarely a primary clinical problem. Part of the overall neck and shoulder-girdle musculature.

Neck stiffness at the base of the neck can involve multiple muscles. This is one component.
## Overview Cervicothoracic stiffness is reduced mobility at the base of the neck where it joins the thorax. Horses may resist lowering the head, have difficulty with lateral bend at that level, or show compensatory posture. Causes overlap with those of cervicothoracic pain. ## Causes Joint restriction, muscle hypertonicity, or pain inhibition. ## Diagnosis Motion palpation and observation of head carriage and bend. ## Treatment Mobilization, stretching, anti-inflammatories, and treatment of any underlying joint disease. ## Recovery and Prognosis Good in most musculoskeletal cases. ## Prevention Regular mobility exercises that encourage lowering and lateral flexion of the base of the neck. Signs include: resistance to lowering the head; reduced lateral bend at the base of the neck; compensatory high head carriage
