NERVOUS SYSTEM Overview of structures and functions: Central Nervous System Brain Spinal Cord Peripheral Nervous System Cranial Nerves Spinal Nerves Autonomic Nervous System Sympathetic nervous system Parasympathetic nervous system AUTONOMIC NERVOUS SYSTEM Sympathetic Nervous System (ADRENERGIC) Parasympathetic Nervous System (CHOLINERGIC, VAGAL, SYMPATHOLYTIC) - Involved in fight or aggression response. - Release of Norepinephrine (cathecolamines) from adrenal glands and causes vasoconstriction. - Increase all bodily activity except GIT EFFECTS OF SNS - Dilation of pupils ( mydriasis ) in order to be aware. - Dry mouth (thickened saliva). - Increase BP and Heart Rate. - Bronchodilation, Increase RR - Constipation. - Urinary Retention. FLUID VOLUME EXCESS - Increase blood supply to brain , heart and skeletal muscles . - SNS I. Adrenergic Agents - Give Epinephrine. [ADRENALIN] Signs and Symptoms: - SNS Contraindication: - Contraindicated to patients suffering from COPD (Broncholitis, Bronchoectasis, Emphysema, Asthma). II. Anti-cholinergic Agents - To counter cholinergic agents. - Atropine Sulfate decreased mucus production Side Effects - SNS Antipsychotics: Haloperidol [Haldol], chlorpromazine Thorazine, etc. Side effect of THORAZINE: atopic dermatitis and foul smelling odor. Side effect of all antipsychotic: signs of PARKINSON‘S DISEA SE, therefore antipsychotic are given together with antiparkinson drugs Anti-parkinson drugs: C.A.P.A.B.L.E.S - Involved in fight or withdrawal response. - Release of Acetylcholine. - vasodilation bronchoconstriction - Decreases all bodily activities except GIT. EFFECTS OF PNS - Constriction of pupils ( meiosis ) . - Increase salivation. - Decrease BP and Heart Rate. - Bronchoconstriction, Decrease RR. - Diarrhea - Urinary frequency. FLUID VOLUME DEF. - antihypertension I. Cholinergic Agents - Mestinon , Neostigmine . Side Effects - PNS II. Beta-adrenergic Blocking Agents - Also called Beta-blockers . - All ending with ― lol - Propranolol [Inderal] , Atenelol , Metoprolol . Effects of Beta-blockers B roncho spasm E licits a decrease in myocardial contraction. T reats hypertension. A V conduction slows down. Should be given to patients with Angina Pectoris , Myocardial Infarction , and Hypertension . ANTI- HYPERTENSIVE AGENTS 1. Beta-blockers ―lol‖ 2. Ace Inhibitors Angiotensin, ―pril‖ (Captopril, Enalapril) 3. Calcium Antagonist Nifedipine (Calcibloc) In chronic cases of arrhythmia give Lidocaine ( Xylocaine )

CENTRAL NERVOUS SYSTEM Brain and Spinal Cord. [Spinal cord terminates at L 1 to L 2 therefore a LUMBAR TAP is performed at L 3 , L 4 or L 5 no risk for spinal cord damage] I. CELLS A. NEURONS Basic cells for nerve impulse and conduction.
