Segmental Organization of the Spinal CordRelationship to Somatic Dysfunction
Question | Answer |
---|---|
How many cervical segments? | 8 |
How many thoracic segments? | 12 |
How many lumbar segments? | 5 |
How many sacral segments? | 5 |
Dermatomes represent? | skin |
Sclerotome represents? | connective tissue |
Myotome represents? | skeletal muscle |
What is the order of the reflex arc? | Muscle spindle Spinal nerve dorsal root ganglion dorsal horn ventral horn ventral root spinal nerve muscle fiber |
Sympathetic control of head and neck is from? | T1-T4 |
Sympathetic control of stomach, liver and gall bladder is from? | T5-T9 |
Sympathetic control of kidney, ureters and bladder is from? | T10-T11 |
IML | Intermediolateral Horn |
Sympathetic control of colon and rectum? | T8-L2 |
What is smypathteic control of the cardiovascular? | T1-T5 |
What is sympathetic control of the respiratory? | T2-T7 |
What is sympathteic control of small intestine? | T9-T11 |
What is IML consist of? | White rami communicans and sympathtetic chain |
What is the visceral innervation? | splanchnic nerves |
Somatic innervation is from? | Grey rami communicans and Spinal nerves |
What is sympathtic innervation of the uterus? | T10-T11 |
What is sympathetic innervation of the prostrate? | L1-L2 |
Is there overlap of dermatome, mytomes and sclermotomes? | yes |
What is the order of reflex to somatic dysfunction? | Afferent Drive -> Facilitated Spinal Cord Segments -> Abnormal Reflexes -> Somatic Dysfunction |
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 |
