Since the sympathetic division travels through t1– l2, how are the organs of the head supplied with sympathetic innervation?

Answers

Answer 1

The organs of the head supplied with sympathetic innervation through the preganglionic neurons of the SANS originate in the thoracic and lumbar (T1 to L2) areas of the spinal cord, with the cell bodies dispersed in four symmetrically and bilaterally distributed regions of the grey matter.

Sympathetic innervation in some cranial nerves' distal branches do not travel from the brain or brain stem. Only in the thoracolumbar area of the spinal cord do sympathetic nerve impulses exit the brain. An element of the autonomic nervous system is the sympathetic nervous system. It is automatic and works with the parasympathetic nervous system to keep the body in equilibrium.

Plasma contains more sodium than chloride. How can this be if individual ions of sodium and chloride exactly balance each other out, and plasma is electrically neutral?.

Answers

In addition to chloride, there are other negatively charged molecules in plasma. The extra sodium restores the balance of the overall negative charges.

What event was khrushchev speaking of when he said the world had come close to ""destroying the human race""?

Answers

The Cuban missile crisis was the event Nikita Khrushchev was speaking of when he said the world had come close to "destroying the human race".

The Cuban Missile Crisis, also known as the October Crisis of 1962, the Caribbean Crisis or the Missile Scare, was a 35-day (16 October – 20 November 1962) confrontation between the United States and the Soviet Union, which escalated into an international crisis when American deployments of missiles in Italy and Turkey were matched by Soviet deployments of similar ballistic missiles in Cuba. Despite the short time frame, the Cuban Missile Crisis remains a defining moment in US national security and nuclear war preparation. The confrontation is often considered the closest the Cold War came to escalating into a full-scale nuclear war.

In response to the presence of American Jupiter ballistic missiles in Italy and Turkey, and the failed Bay of Pigs Invasion of 1961, Soviet First Secretary Nikita Khrushchev agreed to Cuba's request to place nuclear missiles on the island to deter a future invasion. An agreement was reached during a secret meeting between Khrushchev and Cuban Prime Minister Fidel Castro in July 1962, and construction of a number of missile launch facilities started later that summer.

The missiles in Cuba allowed the Soviets to effectively target most of the Continental US. The planned arsenal was forty launchers. The Cuban populace readily noticed the arrival and deployment of the missiles and hundreds of reports reached Miami. US intelligence received countless reports, many of dubious quality or even laughable, most of which could be dismissed as describing defensive missiles.

Only five reports bothered the analysts. They described large trucks passing through towns at night that were carrying very long canvas-covered cylindrical objects that could not make turns through towns without backing up and maneuvering. Defensive missile transporters, it was believed, could make such turns without undue difficulty. The reports could not be satisfactorily dismissed.

What is the arrangement of the phospholipids a substance encounters as it passes through the plasma membrane?

Answers

The phospholipids in the plasma membrane are arranged in two layers, called a phospholipid bilayer, with a hydrophobic, or water-hating, interior and a hydrophilic, or water-loving, exterior.

Phospholipids are a class of lipids whose molecule has a hydrophilic "head" containing a phosphate group and two hydrophobic "tails" derived from fatty acids, joined by an alcohol residue (usually a glycerol molecule). Marine phospholipids typically have omega-3 fatty acids EPA and DHA integrated as part of the phospholipid molecule. The phosphate group can be modified with simple organic molecules such as choline, ethanolamine or serine.

Phospholipids are a key component of all cell membranes. They can form lipid bilayers because of their amphiphilic characteristic. In eukaryotes, cell membranes also contain another class of lipid, sterol, interspersed among the phospholipids. The combination provides fluidity in two dimensions combined with mechanical strength against rupture. Purified phospholipids are produced commercially and have found applications in nanotechnology and materials science.

In aqueous solutions, phospholipids are driven by hydrophobic interactions, which result in the fatty acid tails aggregating to minimize interactions with the water molecules. The result is often a phospholipid bilayer: a membrane that consists of two layers of oppositely oriented phospholipid molecules, with their heads exposed to the liquid on both sides, and with the tails directed into the membrane. That is the dominant structural motif of the membranes of all cells and of some other biological structures, such as vesicles or virus coatings.

Phospholipid bilayers are the main structural component of the cell membranes.

In biological membranes, the phospholipids often occur with other molecules (e.g., proteins, glycolipids, sterols) in a bilayer such as a cell membrane. Lipid bilayers occur when hydrophobic tails line up against one another, forming a membrane of hydrophilic heads on both sides facing the water.

In "antagonistic muscle pairs," muscles function. A pair of muscles work together to move a body part, and then the other muscle in the pair works together to bring the body part back to its starting position.

Antagonizing pairs of muscles are those that function in this way. When two muscles are antagonistic, one contracts while the other relaxes or lengthens. The muscle that is lengthening or relaxing is referred to as the antagonist, while the muscle that is contracting is referred to as the agonist.

Answers

The isotopes in order from longest half-life (3) to shortest half-life are Uranium-238-Lead-206 Dating, Carbon-14 Dating, and Potassium-Argon Dating.

Isotopes are two or more different atom types that share the same atomic number and are placed in the periodic table but have different quantities of neutrons in their nuclei, resulting in various nucleon numbers.

The duration needed for a quantity of a radioisotope to decay by half is known as its radioactive half-life. The majority of the radioactivity will disappear within a few days if an isotope has a half-life of only a few hours or less.

Uranium-238 decays to lead-206 and uranium-235 decays to lead-207 in uranium-lead dating. While carbon-14 has a half-life of only 5,730 years, uranium-lead dating can be used to date rocks that are billions of years old.

The half-life of carbon-14 is 5,730 40 years, meaning that for the next 5,730 years, half of the radioisotope that is present at any particular time will spontaneously disintegrate.

Potassium-40's half-life is 1.3 billion years, far longer than carbon-14's, making it possible to date even older samples. Due to the prevalence of potassium in rocks and minerals, it is possible to date several samples with geochronological or archaeological value.
