Parasympathetics
- Start in brain or in sacral area
- Nucleus—group of cell bodies in CNS
- Preganglionic—long axon, releases Ach
- Postganglionic—short axon, ganglion right next to target organ, releases Ach
- Cholinergic system
- Don't take many of these b/c can activate both systems (para and sym)
- Atropine—work against parasympathetics ex: have difficulty w/digestion
- Nicotinic and muscurinic receptors
Sympathetics—ch 12
- Found in spine (esp in thoracic area)
- Lateral horn, extension of spinal cord, T1-T12
- Cell body that exits and quickly joins a ganglion
- Preganglionic fiber is short, releases Ach
- Postganglionic fiber is long, releases NE (similar to epinephrine)
- These go to target organs
- E (adrenaline) and NE (noradrenaline) make up catecholamines—Adrenergics
- All cold remedies are adrenergics
- What does sympathetics do? Fight or flight
- Dilate pupils, BP up to put blood where it needs to be, increase rate, dry mouth, inhibits digestive process, increase HCl and mucous, stasis (food doesn't move)
- Excess sympathetic--sympathicotonia
- Pseudoephedarin—in everything, don't take if have heart ds, hypertension,
- Ephedrine—plant Chinese, upper respiratory infections is very effective
- Alpha (NE) and beta (1&2) receptors
- Epinephrine is both alpha and beta
Asthma Attack
- Smooth muscle in the lungs w/Vagus is constricts
- NE is secreted in every tissue of our body
- NE has no affect on bronchial muscles (have beta receptors)
- Korr—simply an enhancer of tissue function
- Adjusting the thoracic area is to bring down the sympathetics to a homeostasis level
- SRS-A—slow reactive substance-anaphylaxis—released from the Mast Cell, most potent bronchoconstriction, increase mucous production
- Should look to increased vagal function first
- Contributing factors
- Subluxation
- Diet—yellow dye #5 is very bad
- Stress
- Habits
- Pollution
- Genetics
- Subluxation area for CNX is upper cervical
- Nodose ganglion
- Upper cervical is excitatory to parasympathetics
Mast Cells
- Activated by NE
- Releases
- Heparin—increase capillary permeability
- SRS-A—most potent bronchoconstrictor
- NCF—neutrophil chemotactic factors
- ECF—parasympathetic rxn
- All of these together cause inflammation
- Inflamed tissues send messages back to upper tspine—afferentation
- Causing fixations and muscle spasms
- Use inhaler and brings in E
- Have b
receptors on the bronchial
- Muscles relax
- Adds to the adrenergic state of the situation
Central Excitatory State—Ch14
- CNS
- Excitatory neurotransmitters released in the cord
- Stays at that level
- An irritant working at a constant rate
- Afferentation—sensory bombardment
- Pain
- Proprioception
