SOLUTIONS
●● Cell Body with nucleus
Answer: Fiber which carries impulses away from cell body
●● schwann cell
Answer: cells which produce myelain or fat layer in the PNS
●● Myelin Sheath
Answer: Lipid layer around the axon; which insulates the axon
●● Node Ranvier
Answer: Gaps or nodes in the myelin sheath
●● impulse
Answer: -self propagating
-mechanism, potassium and sodium pump
●● synapse
,Answer: -junction between neurons
-the neurons do not actually tough at the synapse
-neurotransmitters used to restart impulse in dendrite of 2nd neuron
●● neurotransmitters
Answer: -chemicals in the junction which allow impulses to be started in
the second neuron
●● brain
Answer: know these terms:
-brain stem
-diencephalon
-cerebellem
-cerebrum
●● spine
Answer: know these terms:
-spinal cord
●● lobes of the cerebrum
Answer: frontal, parietal, temporal, occipital
,●● special regions (of the brain)
Answer: broca's area, wernicke's area, limbic system
●● brain waves patterns - beta
Answer: -concentration, arousal, alertness, cognition
-higher levels associated with anxiety, diease, feelings of sparation, fight
or flight
●● brain waves patterns - alpha
Answer: -relaxation, superlearning, relaxed focus, light trance, increased
serontonin production
-pre-sleep, pre-walking drowsiness, mediation, beginning of access to
unconscious mind
●● brain waves patterns - theta
Answer: -dreaming sleep (REM sleep)
-increased production pf catecholamines, increased creativity
-integrative, emotional experiences, potential change in behavior,
increased retention of learned material
-hypnagogic imagery, trance, deep mediation, access to unconscious
mind
●● delta
, Answer: -dreamless sleep
-human growth hormone released
-deep, trance-like, non-physical state, loss of body awareness
-access to unconscious and "collective unconscious" mind, greatest
"push" to brain when induced with Holosync
●● cranial nerves
Answer: -12 pair
-attached to undersurface of brain
●● spinal nerves
Answer: -31 pair
-attached to spinal cord
●● autonomic nervous system
Answer: -regulates bodies involuntary responses
-two divisions:
--sympathetic (emergency response, fight or flight)
--parasympathetic (normal everyday conditions)
●● major sense organs
Answer: -visions (eye)
