Autonomic Nervous System

12.9K
The autonomic nervous system (ANS) is a critical component of the peripheral nervous system, primarily responsible for regulating involuntary bodily functions and maintaining homeostasis. It functions in tandem with the central nervous system (CNS) to seamlessly coordinate various physiological processes without the need for conscious control.
The ANS comprises two main divisions: the sympathetic and parasympathetic divisions. These divisions function antagonistically to maintain a dynamic...

Autonomic Nervous System: Overview

7.6K
The human nervous system is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is composed of the brain and spinal cord, while the PNS contains nerve cells, clusters of nerve cells, and the sensory receptors that are outside the CNS. The PNS has two types of nerve cells: sensory (afferent) and motor (efferent). Sensory cells send signals to the CNS from receptors, and motor cells carry signals from the CNS to organs, muscles, and...

Disorders of the Autonomic Nervous System

1.6K
The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.
Raynaud's disease, also known as Raynaud's...

Setting Time of Cement01:12

Setting Time of Cement

709
The setting time of cement refers to the process of cement paste transitioning from a plastic state to a solid state. This process is crucial in construction as it dictates the timeframe for concrete placement, compaction, and finishing. The onset of this solidification is termed the initial set, indicating when the paste becomes unworkable. The final set is when the paste has solidified completely, and further handling or manipulation can no longer affect its shape. The cement strength is...

Drugs Acting on Autonomic Ganglia: Stimulants

2.1K

Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...

Summary

The study reveals how melanocortin 4 receptors (MC4R) in the autonomic nervous system regulate energy balance. Specific MC4R locations in neurons influence metabolic control.

Area of Science:

  • Neuroscience
  • Metabolic Regulation
  • Autonomic Nervous System

Background:

  • The central nervous system (CNS) melanocortin (MC) system and the autonomic nervous system (ANS) are crucial for maintaining energy homeostasis.
  • Understanding the precise roles of MC receptors, particularly MC4R, within the ANS is essential for metabolic research.

Discussion:

  • Rossi et al. (2011) investigated the metabolic functions of MC4 receptors by examining their specific anatomic localization within the ANS.
  • The study utilized MC4R-knockout (MC4R-KO) mice, re-expressing MC4R subpopulations in either cholinergic or brainstem neurons to delineate receptor functions.

Key Insights:

  • Specific neuronal populations expressing MC4 receptors within the ANS differentially regulate metabolic processes.
  • Anatomic localization of MC4R is critical for their function in controlling energy balance.
