Classifying Matter by State02:49

Classifying Matter by State

104.1K
Chemistry is the study of matter and the changes it undergoes. Matter is anything that has mass and occupies space. Matter is all around us; the air, water, soil, mountains, even our bodies are all examples of matter. Matter is divided into three states — solid, liquid, and gas — that are commonly found on earth. The fourth state of matter, plasma, occurs naturally in the interiors of stars.

Breathing

64.6K
The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures. 
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated. 
A mixture is composed of two or...

The Atomic Theory of Matter

129.6K
The earliest recorded discussion of the basic structure of matter comes from ancient Greek philosophers. Leucippus and Democritus argued that all matter was composed of small, finite particles that they called atomos, meaning “indivisible.” Later, Aristotle and others came to the conclusion that matter consisted of various combinations of the four “elements” — fire, earth, air, and water — and could be infinitely divided. Interestingly, these philosophers...

What is Matter?

103.5K
The substance of the universe—from a grain of sand to a star—is called matter. Scientists define matter as anything that occupies space and has mass. An object’s mass and its weight are related concepts, but not quite the same. An object’s mass is the amount of matter contained in the object and is the same whether that object is on Earth or in the zero-gravity environment of outer space. An object’s weight, on the other hand, is its mass as affected by the pull of...

Area of Science:

  • Neuroscience
  • Respiratory Physiology

Background:

  • Breathing is a vital yet complex behavior with measurable physiological outputs.
  • Neural control of breathing involves distinct, compact networks amenable to study.
  • The preBötzinger Complex (preBötC) is a key microcircuit generating rhythmic breathing patterns.

Purpose of the Study:

  • To review progress in understanding the neural mechanisms of breathing control.
  • To highlight the role of the preBötzinger Complex (preBötC) in respiratory rhythm generation.
  • To explore the integration of breathing with orofacial behaviors, emotion, and cognition.

Main Methods:

  • Review of existing literature on respiratory neurobiology.
  • Analysis of studies on the preBötzinger Complex (preBötC) and its components.
  • Examination of research linking neural breathing control to behavior and cognition.

Main Results:

  • The preBötzinger Complex (preBötC) comprises excitatory rhythmogenic and pattern-forming interneurons.
  • These microcircuits generate the essential periodic drive for inspiration.
  • The preBötC integrates breathing with orofacial behaviors and is influenced by emotion/cognition.

Conclusions:

  • Significant progress has been made in deciphering the preBötzinger Complex (preBötC) function.
  • Understanding the preBötC offers insights into the molecular, cellular, and network basis of breathing.
  • Further research promises to fully elucidate the mechanisms underlying this vital behavior.
