Common mistakes in Adrenal gland, two parts two jobs
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Remembering that the adrenal gland has two regions but reversing their hormone classes.
- Assigns mineralocorticoid function to the medulla.
- Confuses cortical steroid hormones with medullary catecholamines.
- Uses cortical steroid functions to explain a medullary defect.
- Chooses medullary catecholamines instead of cortical steroids.
- Treats the adrenal gland as a single endocrine tissue with identical functions throughout.
