The suboccipitals also have an influence on the blood and lymph to/from the brain. Changes to the position of the atlas and axis can impair blood flow to the brain, potentially even affecting lymphatic drainage as well.
The suboccipitals are also going to influence brain blood/lymphatics because of their relationship with the atlas and direct connections to the meninges themselves (dura).

The meninges themselves are innervated by multiple parasympathetic nerves including the vagus and trigeminal nerves. The proximity of the MDBs to these areas suggests that the suboccipitals may influence the activity of these nerves in some capacity.
The meninges receive sensory innervation from the vagus, hypoglossal, facial and trigeminal nerves (among others). These nerves monitor the state of the dura and can help explain the autonomic effects of simple movements involving the eyes, suboccipitals, and tongue.

The suboccipitals also possess connections to the meninges, with tendons inserting directly into the dura. These myodural bridges (MDBs) are thought to help regulate the flow of CSF into the brain.
Movement of the eyes, head, and neck are important contributors to the flow of cerebrospinal fluid. This occurs, in part, due to the "myodural bridges" (MDBs), which connect some suboccipital muscles to the dura mater.

The obliquus capitis inferior possesses the high density of muscle spindles, reinforcing the idea that rotation of the cranium and upper cervical vertebrae is tightly regulated.
The obliquus capitis inferior contains the highest muscle spindle density in the body. It acts like a sensory organ, constantly coordinating rotation of the skull with both the eyes and inner ear. This muscle needs integrated movement and training, not constant release.

The trigeminal nerve, which innervates many of the jaw muscles and parts of the face, can become bothered by compression of the great occipital nerve by dysfunctional suboccipital muscles. This could further worsen TMD.
The suboccipitals can contribute to pain in the face via their connection to the trigeminal nerve by (compression of) the occipital nerve. The trigeminal nerve controls the muscles of the jaw, meaning that weak or dysfunction there may originate from the suboccipitals.

The suboccipitals also respond to movement of the jaw and tongue in order to stabilize the skull as the mouth opens/closes or when the tongue protrudes forward. This implicates them in TMD and disorders of the tongue.
The eyes, via their connection to the suboccipitals, will influence the position of the jaw. This is often associated with lateral asymmetry: the jaw being shifted to one side. Note the proximity of the SO’s to the mandible.

These muscles work together with the (inner) ears and eyes, coordinating balance for even the most basic of movements. Many of the postural muscles that run along the length of the spine respond to information from this system.
While small, these muscles are head of the proprioceptive chain and dictate the tone of the paraspinal muscles. Shifts to one side will inevitability cause the entire spine to compensate subconsciously. This is the same mechanism that allows cats to always land on their feet.
