Which one of the following pairs is incorrectly matched?The islets of Langerhans contain α-cells, which secrete glucagon, and β-cells, which secrete insulin.
So the source of glucagon is the alpha cells, not the beta cells; this pair is incorrectly matched.
Deficiency of insulin leads to diabetes mellitus (correct).
Somatostatin is secreted by the delta cells of the islets (correct).
The corpus luteum (ovary) secretes relaxin in the later phase of pregnancy (correct).
Hence the incorrectly matched pair is glucagon – beta cells.
