Blood supply to the human sternocleidomastoid muscle by the sternocleidomastoid branch of the occipital artery.
The contribution of the sternocleidomastoid branch of the occipital artery, superior arterial pedicle (SAP), to the irrigation of the sternocleidomastoid muscle (SCM) was evaluated in fresh human cadavers by injecting Neoprene-latex for minute dissection. From its insertion in the mastoid process of the temporal bone, the SCM was divided into six levels. The Neoprene-latex injected into the SAP reached the upper three levels in all SCMs studied, which corresponds to the middle part of the studied SCM. In 43.3% of the SCM, this branch reached level four and in 36.6%, it reached level five.
