Endocrine System Flashcards
Name one difference between the endocrine and nervous system
The nervous system reacts immediately for short term change; the endocrine system takes longer to react and its effect is long term
What does the endocrine system regulate?
Growth, development, and reproduction
How does the endocrine system relay messages?
Chemical signals
What are the two parts of the pituitary gland?
Anterior lobe and posterior lobe
Which hormones does the anterior lobe produce?
ACTH, GH, TSH, PRL, FSH, LH, and MSH
Which hormones does the posterior lobe produce?
OXT and ADH
ACTH
adrenocorticotropic hormone
GH
growth hormone
TSH
thyroid stimulating hormone
PRL
prolactin
FSH
Follicle stimulating hormone
LH
luteinizing hormone
MSH
Melanocyte-stimulating hormone
Some organs with secondary endocrine functions
Heart, thymus, adipose tissue, digestive tract, kidneys, gonads
What is direct communication
An exchange of ions and molecules between adjacent cells across gap junctions
Which communication is highly specialized and relatively rare
Direct communication
Which communication occurs between two cells of the same type?
Direct communication
Which communication uses chemical signals to transfer information from cell to cell within single tissue
paracrine communication
what is the most common form of intercellular communication
paracrine communication
What is endocrine communication
Endocrine cells release chemicals (hormones) into bloodstream
What are target cells
Specific cells that possess receptors needed to bind and read hormonal messages
What do hormones do
They stimulate synthesis of enzymes or structural proteins, increases rate of synthesis, and turns existing enzyme or membrane channels on or off
For what is synaptic communication ideal?
Crisis management
Where does synaptic comm. occur?
across synaptic clefts
