pneumotaxic center

Examples of pneumotaxic center in the following topics:

• Pons

  • Within the pons is the pneumotaxic center, a nucleus that regulates the change from inspiration to expiration.
  • The pons also contains the sleep paralysis center of the brain and also plays a role in generating dreams.

• Proprioceptor Regulation of Breathing

  • The pneumotaxic center of the pons sends signals to inhibit the apneustic center of the pons, so it doesn't activate the inspiratory area (the dorsal medulla), and the inspiratory signals that are sent to the diaphragm and accessory muscles stop.

• Role of the Cardiovascular Center

  • Located in the medulla oblongata, the cardiovascular center  contains three distinct components: the cardioaccelerator center, the cardioinhibitor center, and the vasomotor center.
  • The vasomotor center controls vessel tone or contraction of the smooth muscle in the tunica media.
  • Although each center functions independently, they are not anatomically distinct.
  • The cardiovascular center can respond to numerous stimuli.
  • Explain the role of the cardiovascular center in controlling blood pressure

• Center of Gravity

  • The center of gravity is read mathematically as: 'the position of the center of mass and weighted average of the position of the particles'.
  • Three-dimensional bodies have a property called the center of mass, or center of gravity.
  • Given a hollow sphere, the center is the center of mass, even though it does not actually have anything in it.
  • Mathematical Expression: The mathematical relation of center of gravity is read as: 'the position of the center of mass and weighted average of the position of the particles. '
  • Describe how the center of mass of an oddly shaped object is found

• Locating the Center of Mass

  • If a continuous mass distribution has uniform density, which means ρ is constant, then the center of mass is the same as the center of the volume.
  • The experimental determination of the center of mass of a body uses gravity forces on the body and relies on the fact that in the parallel gravity field near the surface of Earth the center of mass is the same as the center of gravity.
  • Thus, the center of mass of a circular cylinder of constant density has its center of mass on the axis of the cylinder.
  • In the same way, the center of mass of a spherically symmetric body of constant density is at the center of the sphere.
  • The intersection of the two lines is the center of mass.

• Center of Mass and Inertia

  • The center of mass for a rigid body can be expressed as a triple integral.
  • In this atom, we will see how center of mass can be calculated using multiple integrals.
  • The center of mass is the unique point at the center of a distribution of mass in space that has the property that the weighted position vectors relative to this point sum to zero.
  • Two bodies orbiting around the center of mass inside one body
  • Use multiple integrals to find the center of mass of a distribution of mass

• Physics and Engeineering: Center of Mass

  • For a continuous mass distribution, the position of center of mass is given as $\mathbf R = \frac 1M \int_V\rho(\mathbf{r}) \mathbf{r} dV$ .
  • In physics, the center of mass (COM) of a mass or object in space is the unique point at which the weighted relative position of the distributed mass sums to zero.
  • In this case, the distribution of mass is balanced around the center of mass and the average of the weighted position coordinates of the distributed mass defines its coordinates.
  • If a continuous mass distribution has uniform density, which means $\rho$ is constant, then the center of mass is the same as the centroid of the volume.
  • The two objects are rotating around their center of mass.

• Buying Centers

  • A buying center is a group of people within an organization who make business purchase decisions.
  • The stock market is an example of a buying center.
  • The employees that constitute the buying center will vary depending on the item being purchased.
  • In a generic sense, there are typically six roles within buying centers.
  • They control the flow of information to and among others within the buying center.

• Neural Mechanisms (Respiratory Center)

  • The medulla oblongata is the primary respiratory control center.
  • The pons is the other respiratory center and is located underneath the medulla.
  • The apneustic center sends signals for inspiration for long and deep breaths.
  • Its signals limit the activity of the phrenic nerve and inhibits the signals of the apneustic center.
  • Describe the neural mechanism of the respiratory center in respiration control

• State-Centered Theories

  • According to state-centered theories of inequality, the government should regulate the distribution of resources to protect workers.
  • This latter period reflects a belief in state-centered theories of inequality, as the state sought to regulate the economy to reduce the exploitation of workers.
  • State-centered theories of inequality emphasize the role of governmental policy and economic planning in producing economic stratification.
  • State-centered theories assert that intentional state policies must be aimed at equitably distributing resources and opportunities.
  • This map of all states to declare themselves officially socialist at some point in history illustrates the spread of state-centered theories of inequality.
