GMS6419 Module 1 Question Paper with
Approved Answers
A network of glands and organs that produces and secretes hormones to regulate various bodily
functions and maintain homeostasis. - correct answers ✔️✔️Endocrine System definition
Specialized structures that produce hormones and release them directly into the bloodstream
(examples: pituitary, thyroid, adrenals, pancreas). - correct answers ✔️✔️Endocrine Gland definition
Chemical messengers produced by endocrine glands that travel through the bloodstream to target
organs/cells where they trigger specific physiological responses - correct answers ✔️✔️Hormone
definition
Specific tissues or cells that have receptors for particular hormones and respond to hormone binding by
changing their activity or function. - correct answers ✔️✔️Target organs/cells definition
Produced as pre-pro-hormones in ribosomes - correct answers ✔️✔️Protein/peptide hormone
synthesis
Modified in the endoplasmic reticulum and Golgi apparatus - correct answers ✔️✔️Protein/peptide
hormone processing
, Packaged into secretory granules - correct answers ✔️✔️Protein/peptide hormone storage
Exocytosis (fusion of secretory granules with cell membrane) - correct answers ✔️✔️Protein/peptide
hormone release
Often released in response to specific stimuli (neural, hormonal, or chemical) - correct answers
✔️✔️Protein/peptide hormone trigger
Derived from cholesterol within cells - correct answers ✔️✔️Steroid hormone synthesis
Generally not stored in vesicles - correct answers ✔️✔S️ teroid hormone storage
Diffuse directly through the plasma membrane due to their lipid solubility - correct answers
✔️✔️Steroid hormone release
Primarily determined by rate of synthesis rather than release of stored hormone - correct answers
✔️✔️Steroid hormone secretion rate
Stored in secretory granules
Released by exocytosis similar to peptide hormones - correct answers ✔️✔️Tyrosine-Derived
Hormones:
Catecholamines (epinephrine, norepinephrine): stored & released
-Stored in thyroid follicles as part of thyroglobulin
-Released after proteolytic cleavage
-Diffuse through plasma membrane after release from thyroglobulin - correct answers ✔️✔T️ yrosine-
Derived Hormones:
Thyroid Hormones (T3, T4): stored, release, after
Negative feedback loops
Neural stimulation
