A cell "without" a "kernel" or nucleus.

  • A (Greek) - Not, Without
  • Nucleus (Latin) - Kernel
  • Red blood cells lack a nucleus
  • Dentate nucleus

    A part of the cerebellum med for its "toothed," or ridged appearance.

  • White matter
  • Motor & nonmotor functions
  • Cerebellum
  • A nucleus of the cerebellum located in deep white matter and connects the cerebellum to the rest of the brain. Important for movement and nonmotor functions.
  • Deoxyribonucleic acid (DNA)

    A set of 4 molecules with 1 "water" molecule removed from ribose "sugar," located within the "kernel," or nucleus of the cell.

    • De (Latin) - Away, Off, Down
    • Oxys (Greek) - Sharp
    • Ribonsaure (German) - Shortened, arbitrary alteration of English arabinose, a sugar fromed from gum arabic
    • Nucleus (Latin) - Kernel
    • Acidus (Latin) - Relating to acid
  • Double helix
  • ACTG
  • Phosphodiester bond
  • Nucleotides
  • The molecules that make up the genetic code. D consists of nucleotides held together by phosphodiester bonds in a double helix. Adenosine, thymidine, cytosine, and guanine are the nucleotides that make up D.
  • Emboliform nucleus

    A small cerebellar "kernel" that contributes to the superior cerebellar peduncles and is "wedged" between the dentate nucleus and the globose nucleus.

  • Brain
  • Cerebellar nucleus
  • Superior cerebellar peduncle
  • Endonuclease

    An "enzyme" that cleaves D at phosphodiester bonds "within" the "kernel" or nucleus.

    • Endon (Greek) - Within, Inside, Interl
    • Nucleus (Latin) - Kernel
    • Ase (English) - Used to form the me of enzymes
  • Enzyme
  • D
  • Cleavage
  • Phosphodiester bond
  • Nucleotide
  • Globose nucleus

    The deep cerebellar "spherical" shaped "kernel" located between the emboliform nucleus and fastigial nucleus.

    HHV4, Epstine Barr, Infectious Mononucleosis

    A virus of the Herpes family, that is the best known cause of infectious mononucleosis or the "kissing disease".

    • Monos (Greek) - Single, alone
    • Nucleus (Latin) - Kernel
    • Osis (Greek) - A condition, disease
  • EBV linked to infectious mononucleosis, oral hairy leukoplakia, nasopharyngeal carcinoma, Burkitt's Lymphoma and Hodgkin Disease. 90% of population harbor EBV and it a transmitted via saliva.
  • No vaccine available
  • Internuclear ophthalmoplegia

    Disorder of conjugate lateral gaze in which the affected eye shows impairment of adduction and the contra lateral eye abducts with nystagmus thus leading to a horizontal diplopia. The communication "between" the PPRF "nuclei" and the oculomotor "nuclei" is disturbed.

    • Inter (Latin) - Among, between, betwixt, in the midst of
    • Nucleus (Latin) - Kernel
    • Ophthalmos (Greek) - Eye
    • Plege (Greek) - Stroke, To Strike
  • Demyelination of the medial longitudinal fasciculus (MLF) is the main cause of this disorder. Multiple sclerosis is the most common cause. Stroke is a possible cause in older patients.
  • Lentiform nucleus

    A "kernel" in the brain that has the "form" of a "lentil"

    • Lens (Latin) - Lentil, a comparison to the convex shape on both sides
    • Forma (Latin) - Form
    • Nucleus (Latin) - Kernel
  • It is a large, coneshaped mass of gray matter just lateral to the internal capsule comprising the putamen and the globus pallidus within the basal ganglia.
  • Mononucleosis

    EBV or CMV infection of B cells, pharynx, and liver. Blood contains large numbers of cells with "single" "kernels" inside them (monocytes).

  • Causes a CD8+ immune response
  • Screened with monospot test that detects IgM antibodies that crossreact with horse or sheep RBCs (CMV does not react)
  • Known as kissing disease
  • Monospot test / heterophile antibodies
  • Nucleosome

    Part of the chromatin structure in which loops of D wrap around histone proteins to make "kernels" forming compact "bodies" of D.

  • Beads on a string
  • Nucleus accumbens

    "Kernellike" area of the basal ganglia responsible for synthesis of GABA, associated with feelings of "reclining," reward, pleasure, addiction, and fear

  • Decreased GABA in anxiety and Huntington's
  • Nucleus ambiguus

    It is a "kernellike" area of the medulla that forms an "isolated" column of gray matter.

  • Contains fibers from CN VII, IX, X
  • Receives visceral sensory information including taste, distension, and baroreceptors
  • PICA stroke leads to dysphagia and hoarseness
  • Why couldn't the pony sing in the choir? Because he was a little hoarse.
  • Nucleus pulposus

    Part of the inner "kernel" area of the intervertebral disk, it is the "soft part of the animal body."
