    Abstract. Since Massion et al. 1 and Duron 2, 3 have emphasized in the cat the important postural function of the external intercostal muscles a comparative study of the activity of the various respiratory muscles and the true postural muscles during sleep, especially REM sleep, seemed of some interest. Because of their anatomical position the external intercostal muscles cannot b e studied in Author: B. Duron, D. Marlot, M. C.

Get this from a library. Respiratory centres and afferent systems = Centres respiratoires et systèmes afférents: colloque, Amiens, mars [Bernard Duron;]. Concise text covers the core anatomy, physiology and biochemistry in an integrated manner as required by system- and problem-based medical courses.

The basic science is presented in the clinical context in a way appropriate for the early part of the medical course. Purchase The Respiratory System - 2nd Edition.

Print Book & E-Book. ISBNThe Brainstem Respiratory Centers are a functionally-defined collection of anatomical loci within the brainstem that coordinate breathing through modulation of the inspiratory and expiratory muscles described in breathing biomechanics. While the brainstem centers can operate independently to maintain normal, quiet breathing, they also receive significant afferent input from a variety of sensory.

So automatic and mechanical is breathing for most of us that we often fail to consider the complexities of respiration. Engaging the lungs, airways, and more, the intake of oxygen and release of carbon dioxide are only the most apparent aspects of a much longer routine.

Although vulnerable Respiratory centres and afferent systems = book various infections and other disorders, the respiratory system by and large continues to function in. The respiratory system normally maintains the partial pressures of arterial oxygen and carbon dioxide within a relatively narrow range.

Because arterial partial pressures of carbon dioxide exert a heavy influence on blood pH, the respiratory system also contributes to the fine-tuning of acid-base balance as discussed further in Respiratory Acid-Base Control.

The respiratory center consists of areas of the brain that are responsible for automatic control of breathing.

Nerve cells in part of the lower brain stem, known as the medulla oblongata, initiate and set the rhythm of r area of the brain stem, called the pons, contains nerve cells that affect the breathing g: book.

If an abnormally low pO 2 is detected, afferent impulses travel to the respiratory centres in the brainstem. A number of responses are then coordinated which aim to increase the pO 2 again. These include: Increasing the respiratory rate and tidal volume, to allow more oxygen to enter the lungs and subsequently diffuse into the blood/5.

Control of breathing involves numerous afferent and efferent neural arcs, including volitional, sensory, and biochemical input and motor output to respiratory muscles, facial structures, and airway effectors.

All of these signals are integrated, modulated, and emitted to effector organs by the brain. Both respiratory centres and the preganglionic vagal motoneurones, which control respiratory (striated) and airway (smooth) muscles respectively, receive information on the lungs, the circulation and the skeletal and respiratory muscles.

Each of these nervous pathways has two components: one is phasic, i.e. in phase with biological rhythms, and comes from mechanoreceptors Cited by:   FUNCTIONS OF RESPIRATORY CENTRES. Genesis of normal respiratory spontaneous rhythm.

Before considering these respiratory responses in detail, it will be necessary to say a few words concerning the receptor organs, the afferent and efferent pathways. The receptor organs concerned with respiration can be divided into two groups: chemoreceptors, organs sensitive to chemical change, and mechanoreceptors, organs sensitive to.

Respiratory Disease and Infection. Respiratory disease is a medical term that encompasses pathological conditions affecting the organs and tissues that make gas exchange possible in higher organisms, and includes conditions of the upper respiratory tract, trachea, bronchi, bronchioles, alveoli, pleura and pleural cavity, and the nerves and muscles of breathing.

The disorders and diseases of this system fall readily into two great classes, according as they affect (1) the respiratory element {the red corpuscle) and its circulation, or (2) the nervo-muscular apparatus, including the lungs and air-passages, the respiratory centre, and the afferent and efferent channels of communication.

The first class. Human respiratory system - Human respiratory system - Blood vessels, lymphatic vessels, and nerves: With respect to blood circulation, the lung is a complex organ. It has two distinct though not completely separate vascular systems: a low-pressure pulmonary system and a high-pressure bronchial system.

In the pons, the pontine respiratory group includes two areas known as the pneumotaxic centre and the apneustic centre.

Nervous System Organization The nervous system integrates and monitors the countless actions occurring simultaneously throughout the entire human body; therefore, every task a person accomplishes, no matter how menial, is a direct result of the components of the nervous system.Secondary effects of chemoreceptors on the autonomic outflows result from changes in lung stretch afferent and baroreceptor activity.

Central respiratory chemosensitivity is caused by direct effects of acid on neurons and indirect effects of CO 2 via astrocytes.
