Endocrine system Flashcards
What is the fight or flight response?
Is a response carried out by the sympathetic nervous system, allowing the stimulation of the adrenal medulla to secrete adrenaline and noradrenaline in to the bloodstream.
Annotate the parathyroid gland
Draw a basic image of the movement of a hormone from its origin to its target.
what are glands responsible for?
Glands are responsible for manufacturing, storing & releasing at least 1 specific molecule called a hormone.
Why is the pancreas part of the foregut and midgut?
The pancreas gets arterial blood supply from both coeliac trunk and superior mesenteric artery.
The pancreas drains in to both venous blood drainage splenic vein and superior mesenteric vein and then in to the hepatic portal vein
The thyroid gland uses iodine to manufacture 2 hormones, what are they called?
Triiodothyronine T3
Thyroxine T4
Annotate the arterial supply of the adrenal glands
Is the parathyroid gland under pituitary control?
no
Which region of the cranial cavity does the pituitary gland sit?
Sphenoid bone
What is a portal system?
A portal system is two venous capillary beds joined by a portal vein
What hormone is secreted after response from LH from the anterior pituitary and what is its function? (In males)
The hormone testosterone is secreted, and it controls
Male secondary sex characteristics
Closure of epiphyseal growth plates
Stimulates sperm production
Where is the pancreas located anatomically?
The pancreas is located in the:
Retroperitoneum
Overlying L1/L2 vertebra
Posterior to the stomach
Anterior to aorta and IVC
Between duodenum and spleen
Annotate the arterial blood supply to the thyroid gland
the gonadal venous drainage system drains in to which major vein?
The right gonadal vein drains directly in the inferior vena cava
Whilst the left gonadal vein makes it way to the left renal vein.
In which system would you find the hepatic portal system and the hypophyseal portal system?
The hepatic portal system would be found in the – Gastrointestinal System
The hypophyseal portal system would be found in the – Endocrine system
What is the difference between the two types of diabetes mellitus?
Type 1 – failure to produce insulin
Type 2 – target cells fail to respond to insulin
The anterior pituitary gland releases its hormones towards the superior vena cava via the?
Hypophyseal veins
Annotate the thyroid
