Endocrine System Review Verified Solutions
- What is the endocrine system?
The endocrine system consists of various glands and clusters of cells that produce hormones essential
for regulating growth, development, and maintaining homeostasis.
Hormones
- What are hormones?
Hormones act as chemical messengers within the endocrine system and are released directly into the
bloodstream.
Types of Hormones
- What distinguishes protein hormones from steroid hormones?
Protein hormones are a category of hormones that cannot easily traverse the cell membrane and are
less likely to be stored in the body. In contrast, steroid hormones can pass through the cell membrane
and can be stored within the body.
Local Hormones
- What are prostaglandins?
Prostaglandins are classified as local hormones that do not enter the bloodstream.
Feedback Mechanisms
- What is positive feedback?
Positive feedback is a process that intensifies a small change, reinforcing the initial alteration.
- What is negative feedback?
Negative feedback describes a response that counteracts the original stimulus.
Mechanisms of Hormone Action
- What is the one messenger model?
The one messenger model refers to the method of hormone action for steroid hormones, allowing
them to deliver their message directly into the target cell.
, - What is the two messenger model?
The two messenger model pertains to protein hormones, which bind to receptors on the cell
membrane, activating internal enzymes to produce the desired effect.
Hormonal Imbalances
- What is hypersecretion?
Hypersecretion occurs when an endocrine gland produces an excessive amount of hormone.
- What is hyposecretion?
Hyposecretion refers to the insufficient production of hormones by an endocrine gland.
Pituitary Gland
- What is the function of the pituitary gland?
Known as the master gland of the endocrine system, the pituitary gland plays a crucial role in
regulating various hormonal functions.
Specific Hormones of the Pituitary Gland
- What is growth hormone?
Growth hormone is secreted by the anterior pituitary and promotes the growth of bones.
- What role does luteinizing hormone play?
Luteinizing hormone, produced by the anterior pituitary, triggers ovulation in females and stimulates
androgen production in males.
- What is the purpose of prolactin?
Prolactin is a peptide hormone released by the anterior pituitary that supports lactation.
- What does FSH (follicle stimulating hormone) do?
FSH is secreted by the anterior pituitary gland during puberty to promote the development of
reproductive cell follicles.
- What does adrenocorticotropic hormone (ACTH) do?
ACTH is released from the anterior pituitary and stimulates the production and secretion of steroid
hormones by the adrenal cortex.
- What are the functions of oxytocin?
