What hormone stimulates gallbladder contraction after a fatty meal?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Cholecystokinin

The core Gastrointestinal physiology relationship supports Cholecystokinin; it is the response that directly accounts for the structural location or physiological change described.

Option by option

  • A. Gastrin

    Gastrin does not fulfill the structural or functional role requested.

  • B. Cholecystokinin (correct)

    Correct. Cholecystokinin is directly supported by the central clue.

  • C. Somatostatin

    Somatostatin is not consistent with the key finding in the stem.

  • D. Secretin

    Secretin is associated with a different gastrointestinal physiology relationship.
