Autonomic nervous system

In this talk, the focus is autonomic nervous system, supported by coverage of the anatomy and functions of the autonomic nervous system, ANS, highlighting how it regulates involuntary processes like heart rate and digestion through its sympathetic and parasympathetic branches. We will examine how these divisions work in opposition to maintain homeostasis, with the sympathetic system enabling fight or flight responses, and the parasympathetic supporting rest and digest functions. The role of neurotransmitters like acetyl coalin and urpinephrne in precise organ control will also be discussed. Finally, we will consider the clinical significance of ANS balance and dysfunction in health and disease. Today, we'll explore the anatomy and function of the autonomic nervous system or ANS. The ANS is a key part of the nervous system, regulating involuntary functions like heart rate, digestion, pupil dilation, and saliva production. Unlike the somatic system, which controls voluntary movements, the ANS works mostly below conscious awareness, maintaining homeostasis by keeping our internal environment stable as conditions change and constantly adjusting organ function. The autonomic nervous system has two main branches, the sympathetic and parasympathetic divisions. The sympathetic division is the fight or flight system, preparing the body for stress or emergencies by increasing heart rate, redirecting blood flow to muscles, and mobilizing energy. The parasympathetic division governs rest and digest,
