Exam 5: Principals of Endocrinology; The Central Endocrine Glands

Indicate which characteristics apply to the hormones below by using the answer code. -synthesized by the endoplasmic reticulum-Golgi complex system

Which molecular precursor is the derivative of estrogens,testosterone,cortisol,and aldosterone?

The _____ is the main link between the nervous system and the endocrine system,due to its control over secretory activities of the _____ glands.

Hormones are classified into which three types?

What occurs in the process of negative feedback?

Indicate which of the features apply to the posterior and anterior pituitary by using the answer code (options may be used more than once or not at all). -may be directly inhibited by negative feedback from its target organ

The majority of hormones fall into the class of ______________________.

Unlike ____________________ hormones,steroid hormones are not stored after their formation.

Neurohormones are hormones that specifically modify neural activity.

MATCHING Indicate whether the characteristics below apply to the endocrine system or the nervous system by using the answer code (options may be used more than once or not at all). -pancreas has ductless cells that secrete

MATCHING Indicate whether the characteristics below apply to the endocrine system or the nervous system by using the answer code (options may be used more than once or not at all). -chemical messengers act at a long distance from their site of secretion

Vasopressin is a vasoconstrictor substance.

Which statement concerning osteoblasts is correct?

____________________ are hormones released into the blood by neurosecretory neurons.

Which statement concerning the hypothalamo-hypophyseal portal system is correct?

Endocrine responses occur more slowly and last longer than neural responses.

Which statement concerning the posterior pituitary is correct?

Hypophysiotropic-hormone secretion by the hypothalamus is regulated only by hormonal negative feedback.

The hormones influence adjustments that require duration rather than speed,whereas the rapid coordinations of the body are controlled by the nervous system.

Indicate which hormone is responsible for each action by using the answer code (options may be used more than once or not at all). -stimulates somatomedin secretion by the liver
