| Question | Answer |
| What movements do somatic nervous system control? | Voluntary Movements |
| Autonomic Nervous System is divided into three types, what are those? | Sympathetic, Parasympathetic and Enteric |
| Also known as Visceral Motor System | Autonomic Nervous System |
| Enteric Nervous System that is located between Circular and Longitudinal Muscle and also functions for Gastrointestinal Motility | Myenteric Plexus |
| Location and Function of Submucosal Plexus | Between Mucosa and Circular Muscle, which regulates blood flow and epithelial function |
| Origin of Sympathetic Nervous System | Thoracolumbar Division (T1-T12, L1-L4) |
| Origin of Parasympathetic Nervous System | Craniosacral Division (CN (1973) X, IX, VII, III and S2-S4) |
| Location of Ganglia of Sympathetic Nervous System and differentiate the length between Pre ganglion fiber and Post ganglion fiber | Near the Spinal Cord (pre - shorter, post - longer) |
| Location of Ganglia of Parasympathetic Nervous System differentiate length between Pre ganglion fiber and Post ganglion fiber | Near Effector Organ (pre - longer , Post - Shorter) |
| Synapse with post ganglionic neuron | pre-ganglionic neuron |
| synapse with effector organ | Post ganglionic neuron |
| Cholinergic Neurons releases __________ | Ach (Acetylcholine) |
| Adrenergic Neurons releases ________ | NE (Norepinephrine) and epinephrine |
| True or False All Pre - ganglionic Neurons are cholinergic Neurons | True (all pre ganglionic neurons releases acetylcholine, ACh) |
| Deactivation of Norepinephrine | reuptake, diffusion and Destruction by enzyme (MAO and COMT) |
| Receptors that activates using ACh | Cholinergic Receptors (Nicotinic and Muscarinic) |
| Two Sub types of Nicotinic Receptor | Nn - Ganglia Nm - Skeletal Muscle |
| Hexamethonium (ganglion blocker) use to block what receptor | Nicotinic sub type Nn |
| D-tubocurare/ D - tubocurarine is used to block what receptor | Nicotinic sub type Nm |
| Atropine blocks what receptor | Muscarinic Receptor |
| Beta Receptor found in the kidneys and heart | Beta1 |
| Beta Receptor found in the lungs | Beta2 |
| True or False Constriction of Pupils is the response mediated by Parasympathetic Nervous System | True |
| True or False Constriction of Blood Vessels is the response mediated by Parasympathetic Nervous System | False (Sympathetic) |
| True or False Sweating of Palm and Soles of feet is the response mediated by Parasympathetic Nervous System | True |
| ___________ Nervous System is responsible for fight or flight response | Sympathetic |
| ___% of Epinephrine and ___% of Norepinephrine is produced by adrenal medulla | 80% epi and 20% norepi |
| What receptor is blocked by hexamethonium at ganglia, but not at the neuromuscular junction? | Cholinergic Nicotinic Receptor (Nn) |
| What autonomic receptor mediates an increase in heart rate? | Beta 1 |
| Stimulation of what receptor stimulates Gs and increases cAMP levels? | Beta1 |
| True or False All sympathetic postganglionic neurons are adrenergic | False (Sweat Glands - cholinergic) |
| What is the Amino Acid that is needed to produce Norepi and Epi that is derived from Phenylalanine? | Tyrosine |
| Deactivation of Acetylcholine (ACh) is mainly by what mechanism? | Reuptake by prejunctional fiber (50% to 80%) |
| True or False Norepinephrine has greater affinity to Beta receptor | False BEAN |
| Alpha receptor that is coupled with G-protein Gq. when activated pupils may dilate | Alpha1 |
| Alpha receptor that decreases cAMP and coupled with G-protein Gi | Alpha2 |
