This post reviews the anatomy of the anterior suboccipital muscles. The suboccipital muscles attach the atlas and axis to the bottom of the occiput. They secure the head on the atlas and fine-tune the movement of the cranium on the atlas and axis. The muscles discussed here are often not included in the list of […]

Sternocleidomastoid Anatomy. The sternocleidomastoid is a two-headed muscle that extends obliquely along the lateral neck. Origin: The sternal head attaches to the superior aspect of the manubrium. The clavicular head attaches to the medial third of the clavicle. Insertion: Both heads merge and attach to the mastoid process of the temporal bone and lateral third
Overview Here, you will find the anatomy and physiology of the splenius cervicis muscle. Splenius cervicis is a broad, flat muscle that wraps around the lateral neck. It anchors in the upper thoracic vertebrae and inserts on the upper cervical vertebrae. This makes it a “jack of all trades, master of none,” as it assists
Overview Splenius capitis is a broad, flat sheet that originates along the mid-line of the neck’s base. It wraps the lateral muscles and inserts onto the lateral base of the skull. Its relationship with the splenius cervicis complicates the anatomy. Origin Insertion Function Innervation Origin Insertion Function Innervation Wikipedia entry for Splenius Capitis Posts Related

The posts related to anterior suboccipital muscles are included in the grid below. The suboccipital muscles attach the atlas and axis to the bottom of the occiput. They secure the head on the atlas and fine-tune the
The anatomy of thoracic outlet structures is complex in several ways. First, many of the bones are both origin and insertion for muscles. Second, several of the muscles have statistically significant variations in cadaver studies. Here, you will find a brief overview of Thoracic Outlet Syndrome followed by a walk-through of the structures from back
Overview Scalene anatomy is more variable than most muscles. They vary in their attachments and size in 40-71% of the reviewed studies. Scalenes are 3 (sometimes 4) muscles on either side of the neck. This is one of those muscles that makes it hard to say which end is the origin and which end is
Overview Semispinalis capitis anatomy is significant for managing pain. It is a large muscle that extends the head, perpetuates forward head posture, and squeezes the greater occipital nerve. Origin Insertion Function Nerve The functional anatomy of semispinalis capitis is significant regarding upper cervical pain. It attaches to the occiput and then usually skips the first
