Dopamine
Pain block
Endorphins
Maintains pregnancy
Progesterone
Mood, appetite
Serotonin
Lowers blood sugar level
Insulin
Regulates metabolism
Glucocorticoid
When do diabetics take insulin?
When levels of glucose in the blood are at high levels
How does the adrenal gland help us when we are afraid
It releases hormones that increase heart and breathing rates, and makes glucose available to our muscles
The nervous system is to a telephone as the endocrine system is to a
Radio broadcast
The endocrine system
Releases hormones into the bloodstream
A thermostat is a good example of a
Feedback system
One way the endocrine system helps maintain homeostasis is by having
Two hormones with opposite effects regulate certain things
Which gland produces epinephrine and norepinephrine
Adrenal
Located at the base of the brain, superior
Hypothalamus
Maintains all homeostasis in body to brain
Hypothalamus
Not part of the endocrine system but it controls the release of hormones from it
Hypothalamus
Part of brain that connects the nervous system to the endocrine system
Hypothalamus
Located at the base of brain, inferior
Pituitary gland
The boss of the endocrine system. Controls all other glands
Pituitary gland
Pea sized structure
Pituitary gland
Store house for hormones they were produced by the hypothalamus
Neurohypophysis
Located deep in center of brain
Pineal gland
Maintains circadian rhythm
Pineal gland
Regulates reproductive hormones
Pineal gland
Fight or flight response
Adrenal gland
Active during puberty than shrinks away
Thymus gland
Regulates calcium levels
Parathyroid gland
Regulates blood sugar
Pancreas
What are the five responses to fight or flight
- Increase in strength
- No feelings of pain
- Heightened senses
- Sudden burst of energy
- Increased breathing rate
What glands are involved in the fight or flight response
Hypothalamus
Pituitary
Amygdala
An initial change causes a stimulus, furthering the change in the same direction
Positive feedback
What are examples of positive feedback
Fight or flight Childbirth Blood clotting Lactation Ovulation
The output shuts off the original stimulus or reduces its intensity
Negative feedback
What are examples of negative feedback
Blood glucose regulation
Thyroid hormone release
Red blood cell production
