  • Spinal Reflexes

    • Spinal reflexes include the stretch reflex, the Golgi tendon reflex, the crossed extensor reflex, and the withdrawal reflex.
    • Spinal reflexes include the stretch reflex, the Golgi tendon reflex, the crossed extensor reflex, and the withdrawal reflex.
    • The crossed extensor reflex is a withdrawal reflex.
    • The withdrawal reflex (nociceptive or flexor withdrawal reflex) is a spinal reflex intended to protect the body from damaging stimuli.
    • Some of these send motor impulses to the flexors to allow withdrawal.

    • Required reserve ratio equals 5%; the banks hold zero excess reserves, and the public does not withdraw money out of their currency accounts.
    • Required reserve ratio equals 20%; the banks hold zero excess reserves, and the public does not withdraw money out of their currency accounts.
    • Compute the change in the M1 definition of the money supply if a person withdraws $5,000 in cash from his checking account.

  • Multiple Investments

    • Present value formula is flexible because it can handle uneven withdrawals and investments.
    • Withdrawal or deposit determines the sign.
    • A withdrawal is negative, while a deposit is positive.
    • Value of your withdrawals and deposits equals $520.03 at the end of Year 3.

  • A Bank Failure

    • If depositors begin withdrawing funds, the banks can sell the liquid securities and pay the depositors' withdrawals.
    • Thus, your bank has enough funds to meet depositors' withdrawals.
    • Depositors withdraw $10 million that decreases deposits by $10 million.

  • Causes of Banking Crises

    • Banking crises are when there are widespread bank runs: an abnormal number depositors try to withdraw their deposits because they don't trust that the bank will have the deposits for withdrawal in the future.
    • Bank Run: A bank occurs when many people try to withdraw their deposits at the same time.
    • This can quickly induce panic in the public, driving up withdrawals as everyone tries to get their money back from a system that they are increasingly skeptical of.
    • This caused a large number of people to the banks to withdraw, which in turn motivated others to go to the banks and get their capital out also.
    • Since banks lend out some of their deposits, they did not have enough cash on hand to meet the immediate withdrawal requests (they became illiquid) and therefore went bankrupt.

  • Acidity of Carboxylic Acids

    • For example, alcohols have pKa's of 16 or greater but their acidity is increased by electron withdrawing substituents on the alkyl group.
    • The following diagram illustrates this factor for several simple inorganic and organic compounds (row #1), and shows how inductive electron withdrawal may also increase the acidity of carboxylic acids (rows #2 & 3).
    • Alcohols are slightly less acidic than water, due to the poor electronegativity of carbon, but chloral hydrate, Cl3CCH(OH)2, and 2,2,2,-trifluoroethanol are significantly more acidic than water, due to inductive electron withdrawal by the electronegative halogens (and the second oxygen in chloral hydrate).
    • Electronegative substituents increase acidity by inductive electron withdrawal.
    • The methoxy group is electron donating and the nitro group is electron withdrawing (last three entries in the table of pKa values).

  • Substance-Related and Addictive Disorders

    • Substance-use and addictive disorders are marked by physiological dependence, drug-seeking behavior, tolerance, and/or withdrawal.
    • This state creates the conditions of tolerance and withdrawal.
