Autonomic Nervous System

Let us learn about the Autonomic Nervous System in this Pharmacology lecture only on sqadia.com. Many systems of the body (e.g., digestion, and circulation) are controlled automatically by the autonomic nervous system (and the endocrine system).

Control of the autonomic nervous system often involves negative feedback, and there are many afferent (sensory) fibers that carry information to centers in the hypothalamus and medulla. These centers control the outflow of the autonomic nervous system, which is divided on anatomical grounds into two major parts:

  • Sympathetic System

  • Parasympathetic System

Learn the details about them in the video!

Effects of Sympathetic Stimulation

It usually includes all kinds of Fight or Flight reactions that are:

  • Pupil Dilation

  • Bronchiolar Dilation

  • Increase Heart Rate

  • Vasoconstriction

Learn more by watching the video!

Autonomic Nervous System: Adrenoceptors

They are of two types:

  • α-Adrenoceptors

  • β-Adrenoceptors

Their location and functions are mentioned in the video!

Autonomic Nervous System: Acetylcholine

Acetylcholine is released from different types of nerve fibers while its receptors are of two types:
