Exam 22: The Endocrine System

Cortisol, the main glucocorticoid from the zona fasciculata, depresses the immune response and inflammation.

In the adrenal cortex, zona glomerulosa cells secrete

The parafollicular cells (C cells) of the thyroid gland produce thyroid stimulating hormone (TSH).

The arrow is pointing to which structure?

The pituitary (hypophysis) and adrenal glands are similar in that each gland has two distinct regions: one that develops from ectoderm, and one that develops from endoderm.

What is the endocrine gland labeled with the arrow?

Which endocrine gland is part of the epithalamus?

Thymosin and other thymic hormones influence the maturation of B cells (B-lymphocytes) in the thymus gland.

Which of the following is NOT a cell type of the pancreatic islets (islets of Langerhans)?

Adipose cells secrete leptin which functions to increase appetite.

Parathyroid hormone (Parathormone) is produced by the follicular cells of the parathyroid gland.

Thyroid follicular cells secrete calcitonin.

Which endocrine gland receives its blood supply from suprarenal arteries?

Somatotrophs are cells located in the _____ which secrete _____.

Alpha and beta cells in the endocrine portion of the pancreas: 1) can be found in the pancreatic islets (islets of Langerhans) 2) secrete their hormones into the pancreatic duct 3 secrete hormones that regulate calcium levels in the body 4) are responsible for maintaining homeostatic levels of glucose 5) aid in the production of enzymes used for protein digestion

What is a tropic hormone (tropin)? Give two examples secreted by the anterior pituitary (adenohypophysis).

Oxyphil cells make up most of the volume of a normal parathyroid gland and are primarily responsible for producing parathyroid hormone (PTH), also called parathormone.

Hormones affect a target cell by binding to specific hormone _____ on the cell membrane or in its interior.

Hypothalamic hormones travel via the primary plexus, the hypophyseal portal veins, and the secondary plexus, where they diffuse into the _____.

Which cell of the pituitary gland releases hormones that target the zona glomerulosa of the adrenal cortex?
