Muscle, Splenius Capitis (M. Splenius Capitis, Pna, Bna, Jna)

The musculature of the human head includes several different muscle groups, including the splenius capitis muscles. The splenius capitis muscles are a long row of deep muscles that are located at the back of the neck and above the spine. They play an important role in supporting and stabilizing the head, as well as allowing movement of the eyeball and ears.

The splenius capitis muscle consists of four main parts - the posterior oblongata, the anterior oblongata and two lateral muscles. Each of these muscles has its own anatomical boundary, and they all combine to form one large splenius muscle. When all four muscles function together, they help maintain balance and stability of the head, stabilizing its position in space.

These muscles also play a key role in controlling the movement of the eyeballs. When a person looks up, this muscle helps lift the head higher, allowing the eyes to focus at the top of the movement. Likewise, when a person looks down, the scapula muscle helps reduce tension on the head, allowing the body to bear weight.

In addition, the capitis muscles play an important role in chewing and other articulatory movements such as nodding and chewing movements. These muscles are able to provide a slight pulling and squeezing impulse, which allows the neck and head to receive additional
