Feedback Mechanisms
The process by which the body maintains a stable internal environment despite changes in external conditions.
Homeostasis
The three types of neurons in the nervous system.
Sensory neurons, motor neurons, and interneurons
The two main components of the CNS
Chemical messengers that travel through the bloodstream to target specific organs and tissues
Hormones
The main function of the urinary system.
removing waste products from the blood and maintaining water-salt balance
This type of feedback loop works to reverse a change and return the body to normal conditions.
This fatty substance forms a protective sheath around axons and increases the speed of nerve impulse transmission.
Myelin
The three main regions of the brain
Forebrain, midbrain, hindbrain
This gland is often called the "master gland" because it controls many other endocrine glands.
Pituatary gland
The four main structures of the urinary system.
Kidneys, ureters, bladder, and urethra
These two pancreatic hormones work together in a negative feedback loop to regulate blood glucose levels.
Insulin and glucagon
This neurotransmitter is overproduced in the brain of a cocaine user
Dopamine
This region of the brain manages basic life functions like breathing, heart rate, and blood pressure.
This gland produces hormones that regulate metabolism, heart rate, and energy levels.
Thyroid
The functional unit of the kidney that filters blood
Nephron
This hormone works with the kidneys to maintain water balance and is released when blood osmolarity increases.
What is ADH
This specialized junction allows neurons to communicate with each other through chemical signals.
This protective barrier prevents harmful substances in the blood from reaching the brain while allowing essential nutrients to pass through.
Blood-brain barrier
These glands produce adrenaline (epinephrine) and cortisol in response to stress
Adrenal glands
This structure in the nephron is where blood is initially filtered.
Bowman's capsule
Addison's Disease
This process involves the movement of sodium and potassium ions across the neuron membrane, creating an electrical signal.
Action Potential
This structure in the brain is responsible for physically connection the right and left hemispheres
Corpus callosum
This condition of the endocrine system is characterized by weight loss, tremors, bulging eyes, and irregular heartrate
Grave's Disease (hyperthroidism)
Trace the complete filtration pathway in the nephron, naming all structures in order.
Bowman's capsule → proximal tubule → Loop of Henle → distal tubule → collecting duct
