Questions and Answers
Combat anxiety - --Answer --the anticipation of danger
Survival stress - --Answer --deadly force threat perception that initiates the
SNS discharge
Combat stress - --Answer --deals with the post event mental & physiological
symptoms that are a result of the SNS activation and the sudden return to the
Parasympathetic Nervous System (PNS). This is known as the PNS "blacklash",
which may distort the memory.
autonomic nervous system (ANS) - --Answer --the organs of our body, such
as the heart, stomach, and intestines, are regulated by the autonomic nervous
system (ANS).
ANS Two Branches - --Answer --the parasympathetic nervous system (PNS)
and the sympathetic nervous system (SNS).

,Motor Skill Classifications - --Answer --there are three basic motor skill
classifications; fine, complex, and gross.
Fine motor skills - --Answer --skills that require hand/eye coordination and
hand dexterity.
When the heart rate reaches 115 BPM, vasoconstriction in the fingers and hands
effects the dexterity required to preform the fine motor skills. - --Answer --
Complex motor skills - --Answer --skills that involve a series of muscle
groups in a series of movements requiring hand/eye coordination, precision,
tracking and timing.
At approximately 145 BPM, complex motor skills begin to deteriorate. - --
Answer --
Gross motor skills - --Answer --skills that involve large muscle or major
muscle groups. Examples of a gross motor skill include simple actions such as a
straight punch, a forward baton strike, or the isosceles shooting stance.

, Parasympathetic Nervous System "Backlash" - --Answer --These are called
backlash triggers and include the perception that the threat has diminished or that
there has been an injury. Trauma to a vital system or exhaustion of the aerobic and
anaerobic systems can also cause this negative backlash.
Critical Incident Amnesia - --Answer --This temporary amnesia will affect
both the officer's memory, and the officer's ability to write an incident report.
Timetable to memory recovery - --Answer --The most complete recovery of

"preliminary" report. A "supplemental" debrief/report should not be prepared
until after the first sleep period, and the final report should be prepared until after
the second sleep period has occurred.
Proteins - --Answer --a group of amino acids that maintain and build muscle
used as an energy source during times of stress and to increase mental
performance.
ATP/PC System - --Answer --The ATP system consists of small energy
bundles that are stored in the muscles. This system is used during high energy and
high strength activities, such as sprinting, lifting heavy weight, or defending against
