Week 5 Endocrine and Genetics Flashcards
What response does the endocrine system elicit?
slower more widespread reaction .
what type of cells are involved in the endocrine system
target cells and receptor cells
what are the two types of hormones involved
lipid (interact with receptors inside) and water soluble (in or on)
what is the role of the hypothalamus?
located below and acts on the pituitary gland
What is the difference between the anterior and posterior
Anterior (And) - makes and releases own hormones.
Blood vessels involved.
Posterior - does not make its own hormones, hormones come from hypothalamus.
Nerves are involved.
What are the two hormones in the posterior pituitary gland
oxytocin and anti-diuretic hormone.
What are the hormones released by the anterior pituitary gland
thyroid hormones (inhibiting)
TH, T3, T4/thyroxine
cortisol (releasing)
which hormone does the adrenal medulla release
cortex - cortisol
medulla - epinephrine
What are the functions of the thyroid hormones
increase basal (rest) and metabolic rate.
stimulate protein synthesis
enhance sympathetic activity
normal growth and development.
which hormones are involved in calcium homeostasis?
parathyroid hormone, calcitonin,
and vitamin D.
Which hormones are involved in glucose homeostasis?
Insulin
Glucagon
What is Hyperglycaemia and Hypoglycaemia
Hyper - high blood glucose.
requiring - glucagon to be released.
Hypo - low blood glucose, requiring - insulin to be released.
