Dissection of anterior and lateral regions of neck
Middle layer of cervical fascia and infrahyoid muscles, anterior view
The external layer of cervical fascia has been removed except in suprasternal space (10). The middle layer of cervical fascia covers the sternohyoid muscles (7) and extends laterally to form a sling-like investment for the omohyoid muscle.
