Dave has discovered a new lipid-soluble hormone. Which of the following is true regarding this hormone? The hormone enters the nucleus of a cell and initiates or alters the expression of a gene, binds to the cell receptors and initiates cAMP activity, enters the cell and activates mitochondrial DNA, or activates the hypothalamic release of regulating hormones.
A series of proteins and enzymes stimulate cAMP to open a sodium channel, causing an action potential in the first-order neuron. This describes which of the following: Generator potential via a second messenger for olfaction, receptor potential for gustation.
Hormones that bind to plasma proteins are water-soluble, activate cAMP to produce hormonal effects, and are made of amino acids and/or proteins. All of the above.
Which hormone would no longer be secreted if the nerve tract from the hypothalamus to the hypophysis were destroyed? Oxytocin, Follicle-stimulating hormone, Growth hormone, or Prolactin.
Which nucleus is responsible for the auditory reflex? Olive, thalamus, inferior colliculus, medial geniculate.
