These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells.

These same compounds also increase secretion of macrophage colony-stimulating factor by osteoblasts, which promotes the differentiation of progenitor cells into osteoclasts, and decrease secretion of osteoprotegerin.

These domains reflect whether the cells have nuclei or not, as well as differences in the chemical composition of the cell exteriors and ribosomes.

These cells and the bacteria trapped inside them entered a symbiotic relationship, a close association between different types of organisms over an extended time.

These principles are motivated by neuroscience insights about learning at the level of nerve cells ( synaptic plasticity ) and the coupling between cortical systems for language and action in the human brain.

These effects are likely mediated in the inferior olive, specifically at low-threshold calcium channels ( LTCC ) which have been shown to modulate the rhythmic firing of cells in this area.

These findings, and others which will in time be developed, will affect the method of glottochronological inquiry.

These signals may positively ( i. e., trigger ) or negatively ( i. e., repress, inhibit, or dampen ) affect apoptosis.

These variations included barrel wear, propellant temperature, different projectiles weights that all affected the muzzle velocity, and air temperature, density, wind speed & direction and rotation of the earth that affect the shell in flight.

These are all the reasons why they are thought to affect " creativity ".

These rates directly affect the rates in the money market, the market for short term loans.

These different factors affect the diamond's hardness, smoothness, conductivity, optical properties and more.

These types of analytics are increasing in popularity as companies demand greater visibility into the performance of call centers and other service and support channels, in order to correct problems before they affect satisfaction levels.

These winds can affect Dublin, but due to its easterly location it is least affected compared to other parts of the country.

These cost from 0 to 3 or more points depending on whether they should be considered Frequent, Major ( or even " Twice Major ", for especially powerful abilities that significantly affect gameplay ) and / or Versatile.

These must be memorized explicitly and affect the use of the part-of-speech suffixes.

" These affect how the power works as well as its final cost.

) These terms all have these properties: they vanish when Ω = 0 ; that is, they are zero for an inertial frame ( which, of course, does not rotate ); they take on a different magnitude and direction in every rotating frame, depending upon its particular value of Ω ; they are ubiquitous in the rotating frame ( affect every particle, regardless of circumstance ); and they have no apparent source in identifiable physical sources, in particular, matter.

These diseases predominately affect males, although females may be carriers of the disease gene.

These replicators respond to selective pressures that may or may not affect biological reproduction or survival.

These are not simple random folds but rather invaginations of the inner membrane, which can affect overall chemiosmotic function .< ref name = Mannella >

These can affect the central nervous system ( brain and spinal cord ), the peripheral nervous system, or the autonomic nervous system.

These laws also affect Jewish law in a number of ways.

These replacement compounds are more reactive and less likely to survive long enough in the atmosphere to reach the stratosphere where they could affect the ozone layer.

These actions affect their characters in different ways, and dealing with the repercussions of having done the " right " ( but unpleasant ) thing is often the major focus of his short stories.

These event chains can significantly affect the course of the project.

These black areas on the upper surfaces of the shuttle's forward wing were added because, at first, shuttle designers did not know how reentry heating would affect the craft's upper wing surfaces.

These results show that different factors affect short-term recall ( disruption of rehearsal ) and long-term recall ( semantic similarity ).

These hormones regulate the rate of metabolism and affect the growth and rate of function of many other systems in the body.

These are then free to take part in chemical reactions that can affect the surface further ( such as acid rain ) or are reformed into other rocks and soils.
