A&P Exam 1: Endocrine system

A&P Exam 1: Endocrine system. The neuroendocrine system performs all of the following except: a) Communication b) Control c) Conduction d) Integration In the endocrine system, secreting cells send hormones to signal specific: a) Basal cells b) Neurons c) Target cells d) Effector cells Endocrine glands are ductless glands; a few endocrine glands are made up of what? a) Neurotransmitters b) Epithelial tissues c) Neurosecretory tissue d) None of the above The thymus gland: a) Promotes development of immune system cells b) Regulates fluid and electrolyte homeostasis A hormone is: a) is any cell with one or more receptors for a particular hormone b) is a regulating substance secreted by an endocrine gland c) is hormones that target reproductive tissues d) is hormones that stimulate anabolism is target cells A tropic hormone is: a) is hormones that target reproductive tissues b) is hormones that target other endocrine glands and stimulate their growth and secretion c) is any cell with one or more receptors for a particular hormone d) none of the above Hormones can be classified as either: A) steroid or nonsteroid B) protein or nonprotein C) cortisol or glycoprotein D) steroid and cortisol What are the categories of non-steroids? a) Proteins b) Glycoproteins c) Peptide d) Amino and derivatives e) All of the above Steroid hormones pass with _____ through phospholipid membranes because they are____ a) Ease, lipid soluble b) Ease, water soluble c) Difficulty, lipid soluble d) Difficulty, water soluble Question: how do hormones work?  Hormones signal a cell by binding to target cell’s specific receptor in a lock and key mechanism Which of the following statements is true? a) Unused hormones are usually quickly excreted by the kidneys b) Unused hormones are usually quickly excreted by the large intestine c) Unused hormones usually stay in the bloodstream d) No hormones go unused In comparison with the nervous system, the regulatory effects of the endocrine system are: a) Rapid to appear, but short lived b) Slow to appear, but long-lasting c) The same, because the systems work together In _____, one hormone produces the opposite effect of another hormone. a) Opposability b) Antagonism c) Permissiveness d) Synergism When a small amount of hormone allows a second hormone to have its full effect on a target cell, the phenomenon is called: a) Synergism b) Antagonism c) Combination d) Permissiveness When you have combination of hormones that act together to produce a greater effect on target cell which is sum of the effects is called: a) Synergism b) Antagonism c) Combination d) Permissiveness Because steroid hormone receptors are not attached to the plasma membrane but seem to move freely in the nucleoplasm, this model of hormone action is called the _____ hypothesis a) Second messenger b) Fixed-membrane receptor c) Mobile-receptor d) None of the above are correct What is the second messenger known as? a) Second messenger b) Hormone-receptor complex c) Fixed-membrane receptor d) None of the above are correct Compare and contrast how non-steroid hormone works?  Understand in own words from text The second messenger system is a form of______ a) Hormone manufacturing b) Signal transduction c) Local regulation d) Reusing or recycling hormones e) Cheating The control of hormonal secretion is usually part of a (an): a) Positive feedback loop b) Negative feedback loop c) Endocrine feedback loop d) Endocrine reflex Which of the following statements is false? a) Both the nervous system and endocrine system use chemicals to send messages b) For the nervous and endocrine systems to function, the receiving cells must have the correct type of receptors c) Cells can have receptors for hormones or for neurotransmitters but not for both d) The nervous system and endocrine systems can be seen as one system- the neuroendocrine system Lecture 2: Endocrine glands The pituitary gland is divided into how many parts? a) Two b) Three c) Five d) It is undivided The stem like stalk that connects the pituitary gland to the hypothalamus is the: a) Hypophysis b) Adenohypophysis c) Infundibulum d) Neurohypophysis Which of the following does not belong to the five adenohypophysis (anterior pituitary)? a) Somatotrophs secrete GH  b) Lactotrophs secrete prolactin  c) Corticotrophs secrete ATCH  d) Thyrotrophs secrete TSH  e) Gondatrophs secrete LH and FSH  f) All of the above belongs Which hormones are produced in the hypothalamus and control hormones of the adenohypopsis? A) Tropic hormones B) Releasing hormones C) Growth-stimulating hormone D) Luteinizing hormone The hormone most likely to cause a shift from glucose catabolism to fat catabolism is the: a) Antidiuretic hormone b) Thyroid-stimulating hormone c) Adrenocorticotropic hormone d) Growth hormone We offer online tutoring and help with assignments for all majors.
