Study Notes
Nervous System Overview
- The autonomic nervous system regulates involuntary functions, controlling the heart, respiratory system, gastrointestinal tract, bladder, eyes, and glands.
- The somatic nervous system is voluntary, allowing control over skeletal muscles.
Neurotransmitters and Medications
- Norepinephrine is the primary neurotransmitter associated with the sympathetic nervous system.
- Drugs mimicking the effects of norepinephrine are termed sympathomimetics.
- The sympathetic branch of the autonomic nervous system is linked to vasoconstriction of blood vessels.
Neurons and Receptors
- Afferent neurons send impulses to the central nervous system for interpretation.
- Beta-2 receptors are responsible for the relaxation of smooth muscle in structures like bronchi, uterus, and peripheral blood vessels.
- Acetylcholine is the neurotransmitter associated with the parasympathetic nervous system.
Drug Types and Actions
- Cholinergic drugs mimic acetylcholine to initiate a response.
- Adrenergic drugs directly stimulate receptors responsive to neurotransmitters like epinephrine and norepinephrine.
- Albuterol, a beta-2 agonist, is primarily used for bronchodilation in asthma management.
- Adrenergic agents that stimulate both alpha-1 and beta-1 receptors are used for treating hypotension and shock.
Sympathetic Responses
- Sympathomimetic or adrenomimetic drugs are known for producing effects similar to sympathetic nervous system activation.
- Dilation of blood vessels leading to increased blood flow is mediated by dopamine-activated receptors.
- Anticholinergic drugs block acetylcholine and prevent corresponding responses.
