Senses & Fascia
Innervation of fascia
The fascia is the most richly innervated system in the body. The fascia is innervated by mechano or proprioceptors that are responsible for positioning and balance. There are also free nerve endings in the fascia that are nociceptors that are embedded in the fascia itself. These nerves are responsible for sensation and touch. When fascia is disrupted with abnormal in growth of fascial fibers and substance, entrapment of these nerves can occur and result in pain.
People with collagen disorder and disruption and changes to the fascia, experience their body and world through the senses in a very different manner than those who have more normal connective tissue.

Sense of smell
People with changes in their connective tissue have a heightened sense of smell. In these people, there is enhanced odor acuity, greater reactivity to smells and also increased odor awareness compared to controls with normal connective tissue.

Internal Function - Interoception
Interoceptive sensitivity is the ability to sense internal bodily arousal like digestion and blood flow. Collagen laxity is linked to interoceptive sensitivity. Interoceptive sensitivity may mediate the relationship between state anxiety and hypermobility. Hypermobile individuals display a heightened neural reactivity to sad and angry scenes within brain regions implicated in anxious feeling states, notably insular cortex.

Anxiety, the senses, collagen disorder
Panic Disorder is high associated with changes in collagen disorder. It is thought to be associated with the enhancement of senses that those with collagen disorder experience. Anxiety is associated with increased physiological reactivity and also increased "interoceptive" sensitivity to such changes in internal bodily arousal.

Autonomic Nervous system
The nervous system itself is composed of connective tissue, the epineurium and perineurium. Therefore abnormalities and changes in connective tissue will affect the nervous system. The fascial layers are also heavily embedded with nerve endings so any changes to the fascia will affect the nervous system. Entrapment, deformation, and biophysical deformative stresses exerted upon the nervous system may alter gene expression, neuronal function and phenotypic expression. There is also evidence of increased numbers and hypersensitivity of nerves in people with connective tissue laxity.
