Study Notes
Autonomic Nervous System
- The autonomic nervous system is responsible for controlling involuntary bodily functions such as heart rate and blood pressure.
Neurotransmitters
- Acetylcholine is the neurotransmitter primarily involved in the Parasympathetic Nervous System (PSNS).
Blood Pressure Regulation
- Mean Arterial Pressure (MAP) is calculated using the equation: MAP = (SBP + 2DBP) / 3, where SBP is systolic blood pressure and DBP is diastolic blood pressure.
Sympathetic Nervous System
- α1 receptors are primarily involved in the constriction of arterioles in the Sympathetic Nervous System (SNS).
- The vasomotor center, located in the medulla oblongata of the brain, is responsible for regulating blood pressure and heart rate in the Sympathetic Nervous System (SNS).
