Chap14 Hormonal Communication Flashcards
Pituitary glands
Produces anti-diuretic hormone for reabsorption of water in kidneys and gonadotropins for ovaries and testes development
Thyroid gland
Produces thyroxine controlling metabolism rate
Adrenal gland
Produces adrenaline increasing heart rate and breathing rate
Testis
Produces testosterone controlling sperm production
Pineal gland
Produces melatonin affecting reproductive development
Thymus
Produces thymosin promoting production of white blood cells
Pancreas
Produces insulin converting glucose into glycogen in liver
Ovaries
Production of oestrogen and progesterone controlling sexual characteristics
Exocrine gland
Produces enzymes that are released via duct into duodenum
Endocrine gland
Produce hormones and release them into blood
Islets of langerhans
Produce insulin (beta cells) and glucagon (alpha cells)
Glycogenolysis
Glycogen stored in liver and muscle broken down into glucose
Increasing BGC
Gluconeogenesis
Production of glucose form non carbohydrates
Glycogenesis
Production of glycogen
What enzyme is activated when adrenaline binds to its receptor?
Adenylyl cyclase
What does increasing cAMP levels activate?
Protein kinases
Medulla oblongata
Controlling heart rate
Accelerator nerve
Transmits impulses increasing heart rate through sympathetic nervous system
Vagus nerve
Sends impulses decreasing heart rate through parasympathetic nervous system
Baroreceptors
Pressure receptors
Detect change in blood pressure
In aorta, vena cava, carotid arteries
Chemoreceptors
Chemical receptors
Detect change in chemical levels in blood
In aorta, carotid artery and medulla
