respiratory zone - contact answerrespiratory bronchioles, alveolar ducts, alveoli What
does the Respiratory Zone do? - contact answerAllow inhaled oxygen to diffuse into the
lung capillaries in exchange for CO2 Conducting Zone - contact answernose, pharynx,
larynx, trachea, bronchi, bronchioles What does conducting zone do? - contact
answerconducts air to respiratory zone, humidifies, warms, and filters air Most common
cancer mutation? - contact answerAcquired What does anticholinergic mean? - contact
answerblockade of muscarinic receptors - This inhibits nerve impulses responsible for
involuntary muscle movements and various bodily functions What does dopamine do? -
contact answerinfluences movement, learning, attention, and emotion. Dopamine
enables neurons in your brain to communicate and control movement. What does
messenger RNA do? - contact answerTranscribes information from the DNA in the
nucleus and carries it to the cytoplasm, and then to the ribosome. Single-stranded,
intermediate molecule. Carries the instructions for making proteins. What do ribosomes
do? - contact answerMake proteins (protein synthesis) Neurotransmitters - contact
answerchemical messengers that cross the synaptic gaps between neurons
Neurotransmitters at the parasympathetic postganglionic synapses - contact
answerAcetylcholine and nitric oxide Atropine Neurotransmitters - contact
answerAtropine is a muscarinic receptor antagonist that is used to inhibit the effects of
excessive vagal activation on the heart, which is manifested as sinus bradycardia and
AV nodal block. Therefore, atropine can temporarily revert sinus bradycardia to normal
sinus rhythm and reverse AV nodal blocks by removing vagal influences. alpha
adreneric receptors - contact answer Beta-adrenergic receptor blockers - contact
answer-Blocks NE/Epi effects on heart - less Ca++ entry -Decreases force of cardiac
contractions What do anticholinergics do? - contact answerDecrease the activity of
acetylcholine (neurotransmitter that regulates movement) Atropine - contact
answermuscarinic antagonist (anticholinergic) beta-adrenergic receptors - contact
answerPortions of the nervous system that, when stimulated, can cause an increase in
the force of contraction of the heart, an increased heart rate, and bronchial dilation.
alpha-adrenergic receptors - contact answerPortions of the nervous system that, when
stimulated, can cause constriction of blood vessels. arachnoid meninges - contact
answermiddle layer - network of fibers and collagen that are part of the suspension
system that helps protect the brain and spinal cord from sudden impact arachnoid
meninges layer function - contact answercontains spinal fluid - connects dura mater and
pia mater. network of fibers and collagen that are part of the suspension system that
helps protect the brain and spinal cord from sudden impact Blood Brian Barrier - contact
answerThe barrier system that restricts the passage of various chemicals and
microscopic entities between the bloodstream and the central nervous system. It still
