What is hormonal regulation? Physiological mechanisms that regulate
hormone secretion and action within the
endocrine system
Why is hormonal regulation essential? It supports brain function cellular energy and
organ survival
What is an endocrine gland? A gland that secretes hormones directly into
the bloodstream
What is a hormone? A chemical substance that stimulates cellular
action in target tissues
What is a target tissue? A tissue affected by a specific hormone
What is a receptor site? A cell surface location where hormones bind to
exert effects
What hormone lowers blood glucose? Insulin
What hormone raises blood glucose? Glucagon
, What is negative feedback? A process where the response reduces
the original stimulus to maintain
homeostasis
How does negative feedback regulate blood glucose? High glucose triggers
insulin release lowering glucose which decreases insulin
secretion
Which pancreatic cells secrete insulin? Beta cells
Which pancreatic cells secrete glucagon? Alpha cells
How does insulin affect glucose movement?It allows glucose to enter the cell
How does glucagon affect glucose storage? It releases glucose from storage
What is glucose regulation? Maintaining optimal blood glucose levels
What is glycogen? Stored glucose in the liver and muscles
What are counter-regulatory hormones? Hormones that raise blood glucose
when levels drop
What is insulin resistance? A condition where cells respond abnormally to
insulin
What is gluconeogenesis? Production of glucose from non-carbohydrate
sources like protein and fat
Which populations are at higher risk for glucose Pregnant
