The Endocrine System Flashcards
Your bodies second communication system
The endocrine system
Glands in your endocrine system secrete ______, another form of chemical messenger, which travel through our bloodstream and influence our behaviors and emotions.
Hormones
Brain region controlling the pituitary gland . This is also called the master gland.
Hypothalamus
Affects metabolism
Thyroid gland
Inner part helps trigger the fight or flight response
Adrenal gland’s
Secretes male sex hormones
Testis
Secretes many different hormones, some of which effect other glands
Pituitary gland
Help regulate the level of calcium in the blood
Parathyroid
Regulates the level of sugar in the blood
Pancreas
Secretes female sex hormones
Ovary
The speedy ___ zips messages from eyes to brain to hand in a fraction of a second. _____ trudge a long in the bloodstream, taking several seconds or more to travel from the gland to the target tissue
Nervous system, endocrine system
These are also called adrenaline and Noradrenaline
Epinephrine, norepinephrine
The endocrine glands control center
Pituitary gland
Among the hormones released by ____ is a growth hormone that stimulates physical development. Another is oxytocin, which enables contractions during birthing, milk flow in nursing, an orgasm.
Pituitary
Also promote social interactions. It’s pleasant release of the companies couples bonding, feelings of group togetherness, and experiences of social trust.
Oxytocin
This feedback system reveals the interplay between the nervous and endocrine system
Brain - pituitary - other glands - hormones - body and brain
Responding to signals from the _____, the pituitary releases hormones that trigger other endocrine glands to secrete hormones, which in turn influence our brain and our behavior.
Hypothalamus
How are the nervous and endocrine systems alike and how do they differ?
Both of these communication systems produce chemical molecules that act on the bodies receptors to influence our behavior and emotions. The endocrine system, which secretes hormones into the bloodstream, delivers it’s messages much more slowly than the Speed nervous system, and the effects of the endocrine systems messages tend to linger much longer than those of the nervous system
Motor and sensory neurons together make up the
Peripheral nervous system
Which of the following is an important part of the endocrine system but is not an endocrine gland
Hypothalamus
The work groups that neurons cluster into are known as
Neural networks
The peripheral nervous system includes the _____ which carry messages from the body to the central nervous system
Sensory neurons
People who engage in Extreme sports often do so to feel the rush of the Fight or flight hormones, epinephrine and norepinephrine. These hormones are released from the ____
Adrenal gland’s
The peripheral Best system that consists of sensory and ____ neurons
Motor
Neuro transmitter is to synaptic gap as hormone is to
Blood stream
Given the proportional amount of the different types of neurons in the human body, the type of neuron you would be least likely to worry about if you lost 100,000 of them would be
Interneurons
