i'm a physical therapist, and know just enough about CST (one 3 hour seminar in grad school, and observing work on my two dd's) to be utterly confused, and not be much use in explaining it to those not familiar with anatomy. with that in mind i'll give it a shot.
first off, it helps to not think of the body as a fixed structure, like a chair, but as a lot of tiny animals (individual cells) who work/live together. like a corporation, say. some corporations work well and smoothly, some muddle along and get tied up in backbiting and self defeating behaviors (like government
our bodies have structure, but it can move (like the big muscles you're aware of; biceps, quads, diaphragm, gut peristalsis) and remodel (like your growing child, healing skin).
a lot of movement goes on at the cellular level, like tiny single muscle cells wrapped around blood vessels. you see the effect of them moving when you blush: they relax, and vessels get bigger so they hold more red
blood, and your face turns pink.
movement also takes place at the molecular level, as we sweat, make tears/saliva/urine, absorb and transport food/O2.
all these cells that make us up are held together by structures we make (like we make hair and fingernails) like elastin and collagen and the calcium crystals in bone. they are part of the "extracellular matrix" which is anything that isn't a living cell. you can see elastin and collagen if you prepare raw meat; it's the tissuey, filmy stuff separating and holding the muscles/organs/nerves/vessels together, allowing them to slide around when we move, but not fall into a heap/puddle on the floor. they also make up non-contractile tissue like tendons and ligaments. there are living cells embedded in the collagen and elastin; they are in charge of doing maintenance so it remains strong but stretchy (and just the right ammount stretchy).
there are also fluid transport systems: blood circulatory, lymph circulatory, and cerebrospinal circulatory. the heart pumps blood out into the arteries, the big muscles squeeze on the veins and push blood back to the heart, the lymph vessels allow extra fluid to seep into them and then the muscles squeeze it back to the heart where it's mixed into the blood again.
your brain and spinal cord (central nervous system = CNS) are bathed in cerebrospinal fluid, it circulates and brings in food/O2 received by exchange across a membrane (the "blood/brain barrier") from the bloodstream. there's no blood in the brain/spinal cord. it's too dangerous: blood is very corrosive and nerves don't heal well, which is why neurological injuries are so devastating. the brain and spinal nerves communicate to the rest of the nerves outside the CNS, and those nerves are different types that we classify in systems named "sympathetic, parasympathetic, autonomic", and such, sort of based on how much voluntary control there is or what they're in charge of.
the cerebrospinal fluid circulates another way than blood/lymph, and i'm sorry, but i've forgotten exactly how. big blank here, and unfortunately this is where the CST comes in. craniosacral therapy (CST) is bodywork (like massage) that works to make a change/effect on the circulation of cerebralspinal fluid, and structures related to the nerves, because if the nerves have dysfunction, then they don't tell the rest of the body how to work properly, and then organs and smooth muscles don't work properly. smooth muscle are the tiny muscles that make a lot of stuff move through organs (like milk letdown, bile secretion), and determine what part of the body gets how much blood (like blushing). if organs don't get enough blood they don't work properly. CST also works directly on the elastin and collagen holding the organs together, because when it (elas/col) is damaged it gets bound down and tight (called adhesions), like a snarl in a pair of nylon stockings. so ducts/vessels can get squished and not allow proper flow of fluids, or organs can get squished and not allow proper function because there's not enough space, or tight corners, or such. imagine if you tried to put on a sweater that was half inside out; how would you get in? or think of clogged plumbing not allowing your sink to drain. CST works on straightening out the kinks and providing good circulation (thus nutrition) in the CNS.
i just previewed this and it's lonnnnng. would you believe i left a lot out?
i hope it's helpful to you, or to someone.
