Endocrine System

Which of the following is one of the two chief types of secreting glands

• Exocrine

• Apocrine

• Merocrine

• Holocrine

The master gland:

• Thalamus

• Hypothalamus

• Thyroid

• Pituitary

What is an advantage of the endocrine system over the nervous system?

• Faster communication

• Specific communication

• Targeted communication

• Broader communication

A hormone is deficient so the number of target receptors increases

• Compensation

• Up regulation

• Down regulation

• Specific regulation

These hormones use transport proteins and enter the cell nucleus directly

• Water-soluble

• Amines

• Peptides

• Lipid-soluble

A secondary hormone is secreted, boosting the effect of the first

• Permissive

• Synergistic

• Agonistic

• Antagonistic

Which of the following is not released by the hypothalamus

• Thyrotropin RH

• Corticotropin RH

• Prolactin inhibiting hormone

• Somatotropin RH

All anterior pituitary hormones act through second-messenger systems. Which of the following is a second messenger?

• Acetylcholine

• Epinephrine

• Norepinephrine

• Cyclic AMP

Which of the following is a non-tropic hormone

• Human growth hormone

• Follicle stimulating hormone

• Thyroid stimulating hormone

• Luteinizing hormone

Inferior to the larynx and anterior to the trachea

• Isthmus

• Thymus

• Thyroid

• Hypothalamus
