The Sympathetic Nervous System (SNS) is crucial for the 'fight or flight' response, regulating homeostasis and various physiological functions. It affects blood glucose, body temperature, heart rate, and more. Developmentally, it forms in the embryonic stage and continues to mature. Dysfunctions in the SNS can lead to health issues like heart failure and hypertension.

Importance of the Sympathetic Nervous System in Maintaining Overall Well-Being
Malfunctions in the sympathetic nervous system can lead to various health issues, highlighting its crucial role in sustaining overall well-being
The sympathetic nervous system works in tandem with the parasympathetic nervous system to regulate homeostasis and maintain a stable internal environment
The sympathetic nervous system is composed of preganglionic and postganglionic neurons
Neurotransmission at Synapses
The sympathetic nervous system uses acetylcholine and norepinephrine to transmit signals between neurons and target organs
Unique Features and Pathways of the Sympathetic Nervous System
The sympathetic nervous system has specialized features, such as the release of dopamine in the kidneys and acetylcholine in sweat glands, and diverse pathways, including direct innervation of the adrenal medulla
The sympathetic nervous system influences various organ systems, including the cardiovascular, respiratory, and digestive systems
Sensory signals in the sympathetic nervous system are processed subconsciously and may manifest as referred pain
Health Conditions Linked to Dysfunctions in the Sympathetic Nervous System
Dysfunctions in the sympathetic nervous system can contribute to various health conditions, including cardiovascular diseases, gastrointestinal disturbances, and metabolic disorders
Impact on Mental Health and Physical Ailments
Excessive activity in the sympathetic nervous system is associated with mental health issues such as anxiety and physical ailments like migraines and insomnia

Components of the autonomic nervous system
Includes sympathetic, parasympathetic, and enteric systems.
01
Sympathetic nervous system's role in homeostasis
Maintains baseline activity to regulate stable internal environment.
02
Interaction between SNS and parasympathetic nervous system
SNS mobilizes 'fight or flight'; parasympathetic promotes 'rest and digest'.
