Endocrine-to-endocrine Signal

Processes that occur in a ringdove during courtship behavior: Change in the excitability of neurons in the male's brain by testosterone Type of signal between neurons and endocrine cells:

Endocrine-to-neural

According to some study findings, which of the following may increase the probability that a woman will be gay?

Exposure to slightly more fetal androgen than other fetuses

Composed of a string of amino acids

peptide hormones

(Select all that apply.) -Behaves like a "tomboy" -Seeks a family through adoption -Describes herself as lesbian, especially later in life -Tests higher than most girls in spatial abilities

-Behaves like a "tomboy" -Describes herself as lesbian, especially later in life -Tests higher than most girls in spatial abilities

Identify the differences between the posterior pituitary and the anterior pituitary. (Select all that apply.) -The posterior pituitary's release of hormones is controlled by releasing hormones, whereas the anterior pituitary's release of hormones is controlled by negative feedback. -The posterior pituitary does not produce the hormones it releases, whereas the anterior pituitary produces the hormones that it releases. -The posterior pituitary releases steroid hormones, whereas the anterior pituitary releases amine hormones. -The posterior pituitary releases oxytocin and vasopressin, whereas the anterior pituitary releases tropic hormones.

-The posterior pituitary does not produce the hormones it releases, whereas the anterior pituitary produces the hormones that it releases. -The posterior pituitary releases oxytocin and vasopressin, whereas the anterior pituitary releases tropic hormones.

Composed of four interconnected rings of carbon atoms

Steroid Hormones

In the context of the fraternal birth order effect, who among the following is most likely to grow up as gay?

A boy who has three older brothers

An individual has fully functional testes and normal male internal reproductive structures. However, the external genitalia have not been fully masculinized. The phallus resembles a large clitoris, and though the genital folds contain testes, they resemble labia. Which of the following is the most likely cause of this condition?

A genetic mutation that disables 5-alpha-reductase

A baby is born with a smaller than normal penis, and the scrotum does not contain testes. In addition, the baby has abdominal ovaries. Which of the following treatments is the doctor most likely to prescribe for the baby in the given situation?

Medication to stop the production of androgens

Processes that occur in a ringdove during courtship behavior: details of the particular visual stimulus, such as the opportunity to mate Type of signal between neurons and endocrine cells:

Neural-to-endocrine signal

Processes that occur in a ringdove during courtship behavior: The visual processing that occurs when a male dove sees an attractive female Type of signal between neurons and endocrine cells:

Neural-to-neural signal

Why are only some cells affected by a peptide hormone, and others remain unaffected?

Only the target cells contain receptors that are specific to the hormone.

Composed of a single amino acid that has been modified

amine hormones

A neurobiologist castrates a rat and as a result, the rat stops mating after a few weeks. Which of the following is most likely to occur if the neurobiologist administers testosterone to the rat for a few weeks after it has stopped demonstrating the mating behavior?

the rat will resume the mating behavior.
