    • TRUE OR FALSE
      There is a U-shaped relationship between memory performance and stress hormones
      FALSE
      On the contrary - the relationship has the shape of an inverted U (with increasing hormone levels, memory performance first goes up, then goes down, not the other way around)
    • TRUE OR FALSE
      Corticosteroids improve memory (up to a certain extent)
      TRUE
      Indeed, they have been found to have similar effects to adrenaline
    • TRUE OR FALSE
      An adrenaline antagonist mimics the effects of adrenaline on the nervous system
      FALSE
       on the contrary, it prevents adrenaline from having its usual effect
    • TRUE OR FALSE
      The adrenal cortex responds to hormonal signals from the pituitary gland
      TRUE
    • TRUE OR FALSE
      The adrenal medulla responds to neural signals from the hypothalamus
      TRUE
    • TRUE OR FALSE
      The hypothalamus releases hormones
      TRUE
      It produces both neural signals and hormones - quite an unusual skill set!
    • TRUE OR FALSE
      A "gonadotropin" is a hormone that stimulates the gonads (e.g., causes them to mature, to release hormones)
      TRUE
      a "tropin" is a hormone that stimulates or activates it's target structure - a gonadotropin causes the gonads o mature, an adrenocorticotropin activates the adrenal cortex, etc.
    • TRUE OR FALSE
      Luteinizing Hormone is a gonadotropin that affects the ovaries
      TRUE
       LH and FSH are not sex specific - they both stimulate ovaries as well as testes
    • TRUE OR FALSE
      Luteinizing Hormone is a gonadotropin that affects the testes
      TRUE
      LH and FSH are not sex specific - they both stimulate ovaries as well as testes
    • TRUE OR FALSE
      Primates are bisexual (INHERENTLY, NOT JUST CAN HAVE THE POSSIBLILITY TO BE BISEXUAL)
      FALSE
      Of course homosexual behaviour in all primate species (at least I've not heard of one where that isn't the case), often in individuals who also engage in heterosexual behaviour. Hence, it seems safe to say that all primate species have the capacity for bisexuality and have bisexual individuals (i.e., individuals who regularly engage in both homo- and heterosexual activities)
    • TRUE OR FALSE
      Bonobos are bisexual
      TRUE
      For bonobos, however, bisexuality is the norm: virtually every member of the species regularly engages in both homo- and heterosexual behaviour. Hence in this sense, bonobos (as a species) are bisexual, other primate species are not (even though they do have bisexual individuals).In other words, in this generic form, the statement is true for bonobos, but false for primates in general.
    • TRUE OR FALSE
      Prolonged stress can keep the gonads in an 'immature' (not hormone-secreting) stage of development
      TRUE

      • Adrenaline is released by the pituitary gland
      • Adrenaline acts as a neuro-modulator on the brain

      ou ran several experiments to study the effect of sympathetic arousal on memory, but unfortunately, you lost your lab book, so you no longer know which data set came out of which experiment. Here are data from one of the experiments:
