Study Notes
Autonomic Nervous System
- The Autonomic Nervous System (ANS) is responsible for controlling involuntary actions, such as heart rate, digestion, and breathing.
Sympathetic Nervous System
- The Sympathetic Nervous System (SNS) is responsible for mobilizing energy during emergency situations, known as the "fight or flight" response.
- The primary function of the SNS is to prepare the body for intense activity or emergencies by increasing heart rate, blood pressure, and energy levels.
- During emergencies, the SNS immediately responds by releasing the neurotransmitter norepinephrine, leading to increased heart rate, blood pressure, and energy levels.
- The SNS has alpha-1, alpha-2, beta-1, and beta-2 adrenergic receptors.
- Postganglionic neurons in the SNS have nicotinic receptors.
- The SNS is responsible for selective energy expenditure and catabolic functions.
- The SNS is active during intense activity or emergencies.
Parasympathetic Nervous System
- The Parasympathetic Nervous System (PNS) is responsible for digestion, nutrient assimilation, and energy conservation.
- The primary function of the PNS is to promote relaxation, reduce stress, and conserve energy.
- Postganglionic neurons in the PNS have muscarinic receptors.
- Target tissues in the PNS have muscarinic receptors.
Enteric Nervous System
- The Enteric Nervous System (ENS) is responsible for controlling the gastrointestinal system and is often referred to as the "second brain."
- The ENS is responsible for regulating digestion, absorption, and secretion of hormones.
Homeostatic Mechanisms
- The three essential elements of homeostatic mechanisms are sensors, integrators, and effectors.
Ganglia
- The sympathetic ganglia are located close to the spinal cord and receive gray rami from the intermediolateral cell column in the spinal cord.
- The parasympathetic ganglia are named according to the associated cranial nerves.
- The abdominal ganglia are named according to the associated arteries in the abdomen.
Neurons and Receptors
- Preganglionic neurons in the ANS secrete acetylcholine.
- Postganglionic neurons in the SNS have nicotinic receptors, while target tissues have alpha and beta adrenergic receptors.
- Postganglionic neurons in the PNS have muscarinic receptors, while target tissues have muscarinic receptors.
Autonomic Nervous System Function
- The ANS is responsible for adjusting blood chemistry, respiration, circulation, digestion, immune system, body temperature, and sexual function.
- The ANS plays a crucial role in controlling emotions and responding to stress.
- The ANS is active most of the time, with the SNS dominant during emergencies and the PNS dominant during relaxation.
