Substance P
A neuropeptide acting as a neurotransmitter and as a neuromodulator, it is
normally present in minute quantities in the NS and intestines and is found in
higher concentrations in inflamed tissue. Substance P is a potent vasodilator and
stimulator of smooth muscle contraction and plays a significant role in pain
sensation and the transmission of pain impulses from peripheral receptors to the
CNS. Substance P is also indicated in the regulation of depression and anxiety.
Superficial fascia (SF) (aka panniculus fascia)
Continuous with the dermis, the SF lies directly beneath the skin, supporting the
skin’s structural integrity. Essentially, the SF surrounds the entire torso and the
extremities, surrounding organs, glands and (most but not all) neurovascular
tissues – many of the larger circulatory, lymphatic and neural structures track
through the SF.
Sympathetic nervous system (SNS)
Mediates activity associated with emergency or stress response. When activated,
the SNS facilitates: acceleration of heart rate; elevation of blood pressure;
constriction of peripheral blood vessels; and redirection of blood from the skin
and intestines to the brain, heart and skeletal muscles.
