Endocrine system

    Cards (40)

    • What is the endocrine system?
      A network of glands that secrete hormones
    • How does the endocrine system work with the nervous system?
      It controls vital functions alongside the nervous system
    • What are hormones?
      Chemical messengers secreted by glands
    • How are hormones released into the body?
      They are released directly into the bloodstream
    • Name the major glands in the endocrine system.
      Pituitary gland, adrenal glands, reproductive organs
    • What is the role of the pituitary gland?
      It regulates the endocrine system by releasing hormones
    • What is the adrenal gland's role in the body?
      Facilitates the release of adrenaline
    • What hormones do the testes produce?
      Testosterone
    • What hormones do the ovaries produce?
      Estrogen and progesterone
    • How does the endocrine system maintain hormone levels?
      Through feedback mechanisms involving the hypothalamus
    • What happens when cortisol levels are too high?
      It can lead to Cushing's syndrome
    • What is the primary function of the pituitary gland?
      To influence the release of hormones from other glands
    • What hormones does the anterior pituitary produce?
      ACTH, LH, and FSH
    • What does ACTH stimulate?
      The adrenal glands to produce cortisol
    • What is the role of oxytocin?
      Stimulates uterine contractions during childbirth
    • What are the two parts of the adrenal glands?
      Adrenal cortex and adrenal medulla
    • What does the adrenal cortex produce?
      Cortisol and aldosterone
    • What is the function of adrenaline?
      Prepares the body for fight or flight
    • What do the ovaries produce besides eggs?
      Estrogen and progesterone
    • What is the role of testosterone?
      Development of male characteristics
    • What are endocrine glands?
      Groups of cells that produce hormones
    • How is testosterone production regulated?
      By the hypothalamus and pituitary gland
    • How do hormones influence behavior?
      They affect behavior in different ways
    • What is the endocrine system's primary function?
      To manufacture and secrete hormones
    • What are target cells?
      Cells that have specific receptors for hormones
    • What happens when receptor sites are stimulated?
      A physiological reaction occurs in the target cell
    • Why is timing of hormone release critical?
      It ensures normal functioning of bodily systems
    • What is the effect of low cortisol levels?
      Low blood pressure and poor immune function
    • What is the anterior pituitary responsible for?
      Producing hormones like ACTH, LH, and FSH
    • What does the posterior pituitary release?
      Oxytocin
    • What is the function of aldosterone?
      Maintaining blood volume and pressure
    • What hormones does the adrenal medulla release?
      Adrenaline and noradrenaline
    • What is the role of the hypothalamus in hormone regulation?
      It controls the pituitary gland's hormone release
    • How does testosterone affect men?
      It influences sex drive and muscle strength
    • What is a key characteristic of hormones?
      They travel through the bloodstream
    • What is the significance of the pituitary gland being called the "master gland"?
      It influences the release of hormones from other glands
    • What are the functions of the adrenal cortex and adrenal medulla?
      • Adrenal cortex: Produces cortisol and aldosterone
      • Adrenal medulla: Releases adrenaline and noradrenaline
    • What are the key terms related to the endocrine system?
      • Endocrine Glands: Produce and secrete hormones
      • Endocrine System: Network of glands secreting hormones
      • Hormones: Chemical messengers influencing processes
      • Pituitary Gland: Master gland influencing other glands
    • What are the physiological effects of cortisol?
      • Cardiovascular functions
      • Anti-inflammatory functions
      • Low levels lead to low blood pressure
    • What are the effects of testosterone in males?
      • Development of male characteristics
      • Influences sex drive and sperm production
      • Maintains muscle strength and overall health
