batho-, bathy-

(Greek: deep, depth)

bathesthesia (s) (noun), bathesthesias (pl)
Sensibility to stimuli; such as, pain, movement, and pressure which activate receptors below the body surface but not in the viscera or the internal organs; especially, those in the abdominal cavity: Any bathesthesia includes deep feelings of the joint sensibilities (arthresthesias) and muscle senses (myesthesias).

Sheila had such acute bathesthesia that she could feel a mosquito land on her arm.

bathochromy
A shift of the absorption band toward lower frequencies (longer wavelengths) with deepening of color from yellow to red to black.
batholite
1. A large mass of intrusive igneous rock believed to have solidified deep within the earth.
2. A large emplacement of igneous intrusive (also called plutonic) rock that forms from cooled magma deep in the earth's crust.

Batholiths are composed of multiple masses, or plutons, of magma that moved toward the surface from a zone of partial melting at the base of the earth's crust.

While moving, these plutons of relatively buoyant magma are called plutonic diapirs. Diapirs commonly intrude vertically upward along fractures or zones of structural weakness through more dense overlying rocks because of density contrast between a less dense, lower rock mass and overlying denser rocks.

Because the diapirs are liquefied and very hot, they tend to rise through the surrounding country rock, pushing it aside and partially melting it.

Most diapirs do not reach the surface to form volcanoes, but instead slow down, cool and usually solidify five to thirty kilometers underground as plutons; therefore, the use of the word pluton; in reference to the Roman god of the underworld, Pluto.

batholith
1. A large mass of igneous rock that has melted and intruded surrounding strata at great depths.
2. The large mass of intrusive igneous rocks believed to have solidified deep within the earth.
bathometer
1. An instrument for measuring the depth of a body of water.
2. A device for ascertaining the depth of water; a bathymeter.
3. An instrument that is used to measure water depth without the use of a sounding line.

The bathometer does not require a line to extend to the bottom because it measures the difference in the gravitational effect of the water surface and of solid ground.

bathomorphic
1. Having a deep or myopic eye.
2. Having a larger than normal ocular axial length.
bathophile
Thriving in deep water habitats.
bathophobia
A fear of depths or of descending into depths; such as, occurs occurs when looking down into a well or when going down into a body of water in a submarine.
bathos (Greek)
1. The sudden shift in speech or writing from a lofty level to a lower commonplace one, for contrast or humor, or overdone sentiment that has become melodramatic or maudlin: The actors played the old tear-jerker for bathos and were rewarded with many laughs.
2. Etymology: literally "depth", but figuratively "dull" or "inane", generally to a ludicrous degree.

The term has been misused with pathos, which is something entirely different: the Greek pathos, like the Latin passio, means "suffering", and a pathetic work is one which depicts, or elicits, suffering.

When a captious reviewer denounces a comic's "pathetic" attempts to be funny, what she or he really means is "bathetic".

bathyal
1. A reference to the biogeographic region of the ocean bottom between the sublittoral and abyssal zones.
2. Pertaining to the environment of deposition and the organisms of the ocean between depths of 200 meters [656 feet], the edge of the continental shelf, and 2000 meters [6560 feet].

The bathyal environment is intermediate between the neritic* environment and the abyss*.

*Neritic is a description of the environment and conditions of the marine zone between low tide and the edge of the continental shelf, a depth of roughly 200 meters [656 feet]. A neritic environment supports marine organisms, also described as neritic, that are capable of surviving in shallow water with moderate exposure to sunlight.

The *abyss, or the abyssal, is described as the depositional environment of the deepest area of the ocean basins. The depositional energy is low, the abyssal plain is flat and nearly horizontal, and fine-grained sediments are deposited slowly by waning turbidity currents or from suspension in the water. The water is thousands of meters deep (about 2000 meters) [about 6520 feet], so the water is cold and sunlight is minimal, if it exists at all.

bathyal zone
The biogeographic realm of the ocean depths between 100 and 1000 fathoms (180 and 1800 meters).
bathyanesthesia (s) (noun), bathyanesthesias (pl)
The loss of deep sensations in the body: After the accident, the nerve damage to Harriet's leg resulted in bathyanesthesia.

When people experience bathyanesthesia, it is important that they have an escort at all times because they are in more danger of being injured without being aware of it since they can't feel normal sensations.

bathybic
Pertaining to or dwelling in deepest zone of sea.
bathybius
A name given by Professor Thomas Huxley to a gelatinous substance found in mud dredged from the Atlantic and preserved in alcohol.

He supposed that it consisted of free living protoplasm, covering a large part of the ocean bed. It is now known that the substance is of chemical, not of organic, origin.

More details about bathybius

Bathybius haeckeli was a substance that British biologist Thomas Henry Huxley discovered and initially believed to be a form of primordial matter, a source of all organic life. He later admitted his mistake when it proved to be just the product of a chemical process.

Huxley thought he had discovered a new organic substance and named it Bathybius haeckeli, in honor of the German philosopher Ernst Haeckel. Haeckel had theorized about Urschleim, "original slime", a protoplasm from which it was believed that all of life had originated. Huxley thought Bathybius could be that protoplasm, a missing link (in modern terms) between inorganic matter and organic life.

In 1868, Huxley studied an old sample of mud from the Atlantic seafloor taken in 1857. When he first examined it, he found only protozoan cells and placed the sample into a jar of alcohol to preserve it. Then he noticed that the sample contained an albuminous slime that appeared to be criss-crossed with veins.

bathycardia
A condition in which the heart occupies a lower position than normal but is fixed there, as distinguished from cardioptosia (a condition in which the heart is unduly movable and displaced downward).
