The posterior aspect of the neck is covered by muscles that connect the skull to the spinal column and pectoral girdle. These muscles can be divided into three layers; Superficial layer: Trapezius, splenius capitis and splenius cervicis. Deep layer: cervical transversospinalis muscles (semispinalis capitis, semispinalis cervicis, multifidus cervicis) Deepest layer: suboccipital muscles, interspinales cervicis and intertransversarii colli muscles #anatomy #neckmuscles #neckpaintreatment #neckpain
