| What happens in disease with the input into spinal cord? |
It increases.
There is more input. |
| What is the role of interneurons in spinal reflexes? |
Somatic and visceral afferents send information to the interneurons and then send information to the somatic and visceral efferents. |
| What are the 4 reflexes? |
Somato-somatic reflex
Somato-visceral reflex
Viscero-visceral reflex
Viscero-somatic reflex |
| Somato-somatic reflex |
somatic info comes in and somatic info leaves
normal |
| Viscero-visceral reflex |
Visceral info comes in and visceral info goes out.
(normal) |
| Viscero-somatic reflex |
visceral info comes in but somatic reflex goes out. |
| What is an example of viscero-somatic reflex? |
Referred pain |
| Somato-visceral reflex |
somatic info goes in and visceral into goes out.
somatic input affects a visceral organ |
| Viscero-somatic reflex effects on somatic tissues |
skin
skeletal muscle
tissue texture changes
motion changes
temperature changes |
