Nervous System
This system controls fast body responses using electrical signals.
What is the nervous system?
This is the basic functional cell of the nervous system.
What is a neuron?
This organ is the control centre of the nervous system.
What is the brain?
These chemical messengers are released by endocrine glands.
What are hormones?
These organs filter blood and produce urine.
What are the kidneys?
The two main divisions are the central nervous system and this.
What is the peripheral nervous system?
These branch-like structures receive signals from other neurons.
What are dendrites?
This part of the brain controls balance and coordination.
What is the cerebellum?
This gland is often called the “master gland.”
What is the pituitary gland?
This is the functional filtering unit of the kidney.
What is the nephron?
This division controls voluntary movement.
What is the somatic nervous system?
This long part of the neuron carries impulses away from the cell body.
What is the axon?
This quick automatic response happens before the brain fully processes information.
What is a reflex arc?
This hormone lowers blood glucose levels.
What is insulin?
This hormone helps the kidneys reabsorb more water.
What is ADH?
This part of the autonomic nervous system prepares the body for fight or flight.
What is the sympathetic nervous system?
This fatty covering speeds up nerve impulses.
What is the myelin sheath?
This part of the brain controls breathing and heart rate.
What is the medulla oblongata?
This hormone raises blood glucose levels when blood sugar is too low.
What is glucagon?
When dehydrated, ADH causes urine to become more this.
What is concentrated?
This part of the autonomic nervous system calms the body after stress.
What is the parasympathetic nervous system?
This is the small gap where neurotransmitters cross between neurons.
What is the synapse?
This structure helps you with balance and coordination.
What is the cerebellum?
This gland produces insulin and glucagon to help regulate blood sugar.
What is the pancreas?
This is the process where useful substances like glucose, water, and ions move from the nephron back into the blood.
What is reabsorption: osmosis and active transport?
