Q

Distribution of sympathetic vs. parasympathetic in terms of vascular and visceral supplies

A

Sympathetic: vascular includes fascia, smooth muscle and sweat glands + trunk and extremities; visceral includes smooth muscle, cardiac, nodal and glandular tissue in thoracoabdominopelvic cavity

Parasympathetic: no extremities! Visceral — same as sympathetic but also in viscera of head and neck

Q

What is meant by “allostatic load”?

A

Frequent activation of allostatic systems — continuation of feedback pathways meant to reestablish normal homeostasis

Longterm exposure may cause atrophy of hippocampus affecting feedback, memory, and autonomic function

[allostasis = adaptation in the face of potentially stressful challenges involves activation of neural, neuroendocrine and neuroendocrine-immune mechanisms]

Q

Define spinal facilitation

A

The maintenance of a pool of neurons in a state of partial or subthreshold excitation; in this state, less afferent stim is required to trigger discharge of impulses

Facilitation may be d/t sustained increase in afferent input, aberrant patterns of afferent input, or changes within affected neurons themselves or their chemical environment — once established, facilitation can be sustained by normal CNS activity

A

Louisa Burns, DO

Q

What were the results of Dr. Burns’ research in terms of functional changes as a result of T3 SD?

A

Immediate: rapid, weak, and somewhat irregular pulse

10 minutes later: slightly stronger, slower an dmore regular, but did not return to normal as long as SD persisted

2 months later: gradually weaker with staccato quality similar to that found in elderly [this was not present in rabbits without T3 SD]

29
Q

What were the results of Dr. Burns’ research in terms of functional changes as a result of atlas SD?

A
