Etymology
In English, this muscle’s name is the back, side muscle between the crosswise processes of the neck vertebrae. The word intertransversarii comes from the Latin inter meaning “between” and the Latin term transversus for “crosswise,” which comes from Latin trans meaning “across, beyond, or through” and the Latin verb vertere meaning “to turn.” It is used in reference to the transverse processes of the vertebrae.The Latin term posterior is derived from the Latin post meaning “afterward.”Cervicis comes from the Latin cervix for “neck.”The word lateralis comes from the Latin lata meaning “side.”
Origin
Superior margin of the transverse processes of the cervical vertebrae two through seven
Insertion
Inferior margin of the transverse processes of the superjacent cervical vertebrae one through six
Action
Possibly weakly assist with lateral flexion of the cervical vertebrae. They are most likely proprioceptive transducers that monitor the position and movements of the vertebral column and provide feedback that influences the activity of the larger multisegmental muscles of the vertebral column.
Nerve supply
Branches of the ventral rami of cervical spinal nerves (C2 to C8)
Blood supply
These small muscles receive blood from the ascending cervical artery, which is a small branch of the inferior thyroid artery from the thyrocervical trunk of the subclavian artery.
