Superior Articular Facets - The pair of concave surfaces that articulate with the occipital condyles to form the atlanto-occipital joints.Transverse Foramen - Note these are quite large on the atlas. The following structures are visible on both the Atlas and the Axis. The following structures are on the Atlas only. Rotate the dissection as needed to obtain views from different angles: Using the image below, identify each of the following in your dissection and label them on your worksheet. Named for the mythical person Atlas who supported the world on his shoulders, the atlas (C1) is a ring of bone upon which the head rests and moves. Using the following interactive images to help, locate these foramina on your specimen and label them on your worksheet. The spinous processes of C2 through C6 are often split into two parts (bifid). All cervical vertebrae have 3 foramina, 1 vertebral foramen and 2 transverse foramina through which the vertebral artery and its accompanying vein and nerve pass. Note that cervical vertebrae are smaller than thoracic or lumbar vertebrae. The thoracic and sacral curves retain their original curvature and are called "primary curves." Cervical and lumbar curves are called "secondary curves" since they develop after birth. Later, as the child sits up, stands, and walks, the lumbar curve develops. The cervical curve develops at about 3 months as the head begins to be held erect. Newborns have a single anteriorly concave curve throughout the length of their vertebral column. Label these normal curves on your worksheet. Inferior Articular Processes - These are the articulation points with the vertebrae above and below. Collectively, these processes are attachment points for muscles that move the vertebral column and/or head. Spinous Process - This single posterior projection is from the junction of the laminae.Transverse Processes - Lateral processes extending from the vertebral arch.Vertebral Notches - Superior and inferior indentations in the pedicles of adjacent vertebrae that combine to form an intervertebral foramen through which a spinal nerve passes.Vertebral (Spinal) Canal - Collectively, the vertebral foramina of all the vertebrae form this channel.It contains the spinal cord, some connective tissue, and blood vessels. Vertebral Foramen - This opening lies between the vertebral arch and the body.Lamina - The flat parts of the vertebrae that form the posterior portion of the vertebral arch.Pedicles - Two short, thick processes that project posteriorly, unite with the lamina and form part of the vertebral arch.Vertebral Arch - A bony projection that protects the spinal cord and cauda equina (tail end of the spinal cord) by covering them laterally and posteriorly.Body - The thick cylindrical part of the vertebra that is responsible for bearing weight.Locate the following with the interactive image and correlate anatomy to the specimen. You'll soon discover why we don't use the atlas or axis for this purpose since they differ significantly from the others. We'll use C3 to identify some general vertebral markings and characteristics.

For fission to be self-sustaining, the substance must reach critical mass, the minimum amount of mass required falling short of critical mass limits reaction length to mere microseconds. These large nucleii with more "gaps" can be "split" by the impact of thermal neutrons, so called "slow" neutrons.Ĭonditions must be right for a fission reaction to occur. Although scientists don't yet fully understand why this instability is so helpful for fission, the general theory is that the large number of protons create a strong repulsive force between them and that too few or too many neutrons create "gaps" that cause weakening of the nuclear bond, leading to decay (radiation). The notion of splitting the atom arose from New Zealand-born British physicist Ernest Rutherford's work, which also led to the discovery of the proton.įission can only occur in large isotopes that contain more neutrons than protons in their nuclei, which leads to a slightly stable environment. In contrast, for atomic nuclei heavier than iron or nickel, energy can be released by splitting the heavy nuclei through nuclear fission. For atomic nuclei lighter than iron and nickel, energy can be extracted by combining iron and nickel nuclei together through nuclear fusion. This is why iron is at the top of the binding energy curve. The nucleon of an iron atom is the most stable nucleon found in nature, and it neither fuses nor splits. Moreover, atoms try to become more stable by increasing their binding energy. ![]() ![]() The more binding energy held within the bonds, the more stable the atom. The total amount of energy held within the bonds of atoms is called binding energy. In a typical nuclear reaction involving 235U and a neutron:Ģ36 92U = 144 56Ba + 89 36Kr + 3 n + 177 MeVĪtoms are held together by two of the four fundamental forces of nature: the weak and strong nuclear bonds. Nuclear fission is the splitting of a massive nucleus into photons in the form of gamma rays, free neutrons, and other subatomic particles. Deuterium and Tritium are isotopes of hydrogen.Ģ 1Deuterium + 3 1 Tritium = 4 2He + 1 0 n + 17.6 MeV On Earth, the most likely fusion reaction is Deuterium–Tritium reaction. The energy released in fusion is related to E = mc 2 (Einstein’s famous energy-mass equation). Nuclear fusion is the reaction in which two or more nuclei combine, forming a new element with a higher atomic number (more protons in the nucleus). Hydrogen isotopes (Deuterium and Tritium) are the primary fuel used in experimental fusion power plants.įusion of deuterium with tritium creating helium-4, freeing a neutron, and releasing 17.59 MeV of energy. Uranium is the primary fuel used in power plants. One class of nuclear weapon is the hydrogen bomb, which uses a fission reaction to "trigger" a fusion reaction.įusion is an experimental technology for producing power. One class of nuclear weapon is a fission bomb, also known as an atomic bomb or atom bomb. The energy released by fusion is three to four times greater than the energy released by fission. The energy released by fission is a million times greater than that released in chemical reactions, but lower than the energy released by nuclear fusion. Takes little energy to split two atoms in a fission reaction.Įxtremely high energy is required to bring two or more protons close enough that nuclear forces overcome their electrostatic repulsion. High density, high temperature environment is required.

Some days, as many as 75% of its scheduled flights were grounded. Nearly half of its schedule was canceled during from December 20 to December 29. “We apologize for any inconvenience this may cause, but we’re hoping to get everyone going ASAP,” the airline wrote in another social media post.Ī massive winter storm started the service problems during the holiday season, but Southwest had a much tougher time recovering because of an antiquated crew scheduling system that was quickly overwhelmed, leaving the airline unable to get the staffing it needed to locations to operate flights. Several took to social media to complain about delayed flights. Southwest called the latest problem “intermittent technology issues” in a social media post to customers. Southwest last month unveiled an “action plan” to prevent another operational meltdown. The airline attributed the meltdown in part to changes to its staff scheduling computer systems. The problems come months after the airline was forced to cancel more than 16,700 flights between December 20 and 29, roughly half its schedule during that period. Each time I try, I get a message 'sorry, we found some errors', and cannot proceed. Unlike the other major airlines, Southwest has never charged a fee to check bags, to change your ticket, or to select a seat (after all, it boards in groups using a first-come, first-served.
