Portage Learning, A&P 1, Module 6, Endocrine system Q&A ANATOMY OF THE ENDOCRINE SYSTEM Does the nervous system or endocrine system react faster to external/internal stimuli correct answer - nervous system https://www.stuvia.com/doc/1456023/portage-learning-a-en-p-1-module-6-endocrine-system-q-en-a

Endocrine system and nervous system use what to coordinate activities of body parts correct answer - chemical messengers nervous system: neurons release _____ that excite other neurons correct answer - neurotransmitters Does the nervous system react slower or faster to external stimuli than the endocrine system? correct answer - faster https://www.stuvia.com/doc/1456023/portage-learning-a-en-p-1-module-6-endocrine-system-q-en-a

hormones interact with what in the body correct answer - cells Does the endocrine system react slower or faster to external stimuli than the nervous system correct answer - slower https://www.stuvia.com/doc/1456023/portage-learning-a-en-p-1-module-6-endocrine-system-q-en-a

Why does the endocrine react slower to external stimuli? correct answer - It takes time for hormones to travel through bloodstream to target organ Hormones can react with cells that have what on their cell surface? correct answer - receptor a chemical produced by one set of cells that affects a different set of cells correct answer - hormone Hormones are chemical messengers that can do what? correct answer - influence metabolism of receiver cell https://www.stuvia.com/doc/1456023/portage-learning-a-en-p-1-module-6-endocrine-system-q-en-a

Hormones are also chemical messengers that are sent through the body and produced by what system? correct answer - endocrine All hormones have what 3 three things? correct answer - Origin gland/organ target organ/gland action/function https://www.stuvia.com/doc/1456023/portage-learning-a-en-p-1-module-6-endocrine-system-q-en-a

Many hormones are proteins coded by genes correct answer - true Many hormones are synthesized within what? And then what? correct answer - cytoplasm of ribosomes and then repackaged in golgi apparatus and secreted at plasma membrane Hormones are secreted by what and then sent throughout the body? correct answer - endocrine system 2 categories of hormones are? correct answer - peptide steroid https://www.stuvia.com/doc/1456023/portage-learning-a-en-p-1-module-6-endocrine-system-q-en-a

do peptide or steroid hormones react faster? correct answer - peptide peptide hormones are derived from correct answer - protiens and catecholamines proteins correct answer - *specifically coded for different genes *synthesized in cytoplasm of ribosomes and repackaged in golgi apparatus then secreted through plasma membrane catecholamines are derived from correct answer - amino acid tyrosine Action of peptide hormones correct answer - 1. activate existing enzyme in cell - tend to act quickly for short period of time

- quicker because they activate enzyme that already exists in cell https://www.stuvia.com/doc/1456023/portage-learning-a-en-p-1-module-6-endocrine-system-q-en-a

Steroid hormones are derived from correct answer - cholesterol Steroid hormones act slower. why? correct answer - Because it takes more time to synthesize NEW proteins than it does to activate enzymes already existing in cell Steroid hormones are stored in what kind of droplets correct answer - fat steroid hormones can enter nucleus freely. T or F? correct answer - true - doesn't need to interact with receptor at cell-surface once inside nucleus, steroid hormones do what? correct answer - 1. bind to receptor (creating hormone-receptor complex) 2. the complex activates specific genes that leads to protein synthesis Why do steroid hormones have more of a sustained effect on metabolism of cell than peptide hormone? correct answer - Because they can create NEW protein for cell https://www.stuvia.com/doc/1456023/portage-learning-a-en-p-1-module-6-endocrine-system-q-en-a

2 types of glands correct answer - endocrine and exocrine Endocrine glands correct answer - ductless and secrete hormones directly into bloodstream Exocrine glands (digestive) correct answer - have ducts and secrete contents via ducts, not directly into bloodstream View full exam at: https://www.stuvia.com/doc/1456023/portage-learning-a-en-p-1-module-6endocrine-system-q-en-a
