(3) ANS and Lymphatic System Flashcards
What is the autonomic nervous system?
Involuntary neural control of body functions regulated by the hypothalamus, limbic system and brainstem
What is the anatomic backing for the osteopathic approach to treating viceralsomatic reflexes?
Nearly every interneuron that recieves input from a visceral nociceptor also receives input from a somatic source
***There is NO evidence for any ascending pathway that ONLY transmits visceral signals from the spinal cord to the brain
Which cranial nerves are involved with the parasympathetic nervous system?
III, VII, IX, X
S2-S4
Which spinal levels correlate with sympathetic nervous system?
T1-T12
L1-L2
What are the VS levels for the head/neck?
T1-T5
What are the VS levels for the heart?
T1-T6
What are the VS levels for the lungs?
T1-T7
What are the VS levels for the upper GI?
T5-T10
What are the VS levels for the small intestine/ascending colon?
T9-T11
What are the VS levels for the ascending and transverse colon?
T10-L2
What are the VS levels for the descending and sigmoid colon/rectum?
T12-L2
What are the VS levels for the adrenal?
T5-T10
What are the VS levels for the genitourinary tract (includes bladder)?
T10-L2
What are the VS levels for the ureter (upper/lower)?
Upper = T10-T11
Lower = T12-L2
What are the VS levels for the extremities (upper/lower)?
Upper = T2-T7
Lower = T11-L2
What nerve supplies the PARASYMPATHETIC innervation to the heart, lungs esophagus, upper GI, small intestine, kidneys, ascending/transverse colon, upper ureter?
Vaugs n. (OA, AA)
What nerve supplies the PARASYMPATHETIC innervation to the colon, rectum, reproductive organs, bladder, pelvis, lower ureter?
Pelvic Splanchnic n.
S2-S4 sacrum
What is the key transition point in structures b/w the vagus n. and pelvic splanchnic n. for the parasympathetic innervation?
Upper ureter = Vagus n.
Lower ureter = Pelvic splanchnic n.
Just remember this, and everything above/below it corresponds to that nerve yay..
What are the 4 types of reflexes?
Somatosomatic
Viscerovisceral
Somatovisceral
Viscerosomatic
Define:
Sensitization
Progressive amplification of a response follows repeated administrations of a stimulus
Define:
Habituation
Decrease in a response to a stimulus after repeated exposure to the stimulus over time
“tune out” what isn’t important
Define Allostasis
Process by which the body responds to stressors in order to regain homeostasis
Define Homeostasis
The tendency toward a relatively stable equilibrium between interdependent elements
The majority of the body is drained by the _________ duct
The remainder is drained by the __________ duct
The majority of the body is drained by the THORACIC duct
The remainder is drained by the LYMPHATIC duct
What are considered compensated zinks patterns?
What are considered UNcompensated zinks patterns?
