endocrinology Flashcards
name 2 types of fat soluble hormone classes
Iodotyronines
Cholesterol derivatives and steroids
name 2 types of water soluble hormone classes
Amines
Peptides
name some factors which may control hormone action
hormone metabolism
hormone receptor induction(hormone induces another hormone)
home receptor down regulation
synergism ( 2 hormone result in amplified effect)
antagonism (1 hormone opposes another)
where is Oxytocin and ADH produced
the hypothalamus
they are secreted in the posterior pituitary.
which hormones are produced in the anterior pituitary gland
TSH, ACTH, FSH, LH, Growth hormone, prolactin
how are anterior pituitary hormones produced
specific hormone produced n the hypothalamus stimulates the anterior pituitary to produce the corresponding hormone
what might indicate pituitary dysfunction
tumour mass effect (causing anatomical damage and symptomatic)
hormone excess
hormone deficiency
name 9 thyroid hormone functions
food metabolism protein synthesis carb metabolism fat metabolism ventilation rate CO HR Growth rate brain development of foetal and postnatal
in all these cases, thyroid hormone increases the process
Thyroid glands produce 80% T4 hormone and 20% T3, why is T3 hormones the most metabolically active in the body?
In tissues, T4 hormones are converted to T3 hormones, therefore they are more metabolically active as they are more abundance in tissues
what are the 4 main stress hormones in the body
acute secretion glucagon epinephrin soon after cortisol glucorticoid
what are the risks of obesity
Type 2 diabetes hypertension coronary artery disease stroke osteoarthrosis obstructive sleep apnoea carcinoma
which type of fat poses more risk: visceral or subcutaneous fat
visceral fat, as it surrounds body organs
