Brain Anatomy
This is the largest part of the brain, responsible for conscious thought and reasoning.
What is the Cerebrum?
These branches on a neuron receive signals from other neurons.
What are Dendrites?
This system consists of just the brain and the spinal cord.
What is the Central Nervous System (CNS)?
This type of specialized doctor diagnoses and treats brain disorders.
What is a Neurologist?
Located at the back of the brain, these lobes are responsible for vision.
What are the Occipital Lobes?
Often called the "little brain," this structure located below the cerebrum coordinates movement and balance.
What is the Cerebellum?
This fatty substance acts as insulation around the axon to help signals move quickly.
What is the Myelin Sheath?
This system consists of all the nerves outside of the brain and spinal cord.
What is the Peripheral Nervous System?
This diagnostic scan uses magnetic fields and radio waves to create a detailed 3D image of the brain.
What is an MRI (Magnetic Resonance Imaging)?
These lobes are responsible for processing smell and sound, as well as understanding language.
What are the Temporal Lobes?
This structure connects the brain to the spinal cord and controls vital functions like breathing and heart rate.
What is the brain stem?
This is the tiny gap between two neurons where the signal must jump across.
What is the Synapse?
Often described as "cables" running throughout your body, the Peripheral Nervous System is made up of these structures, which are actually bundles of individual neurons wrapped together.
What are nerves?
This test measures how fast an electrical signal moves through a nerve to identify nerve damage.
What is a Nerve Conduction Velocity test?
This lobe plays a large role in personality, planning, and voluntary muscle movement.
What is the Frontal Lobe?
These are the two distinct halves of the cerebrum.
What are the Left and Right Hemispheres?
These are the chemicals that help transfer a signal across the synapse.
What are Neurotransmitters?
Any type of information (or "stimuli") sent to the brain collected by your eyes/ears/touch/mouth/nose.

What is Input?
This condition, affecting movement and coordination, is caused by brain injury or malformation during development. It can only happen during or immediately after childbirth.
What is Cerebral Palsy?
This specific area within the frontal lobe is responsible for voluntary control of skeletal muscles.
What is the Motor Cortex?
This broad band of nerve fibers connects the two hemispheres, allowing them to communicate.
What is the Corpus Callosum?
If a signal is headed for a muscle, this specific type of neuron is the final one in the chain to stimulate the muscle fibers.
What is a Motor Neuron?
This clear, colorless liquid surrounds and cushions the brain and spinal cord.
What is Cerebrospinal Fluid (CSF)?
This type of scan uses X-rays from multiple angles to create a 3D picture of the head.
What is a CT Scan?
A person with an injury to this lobe might have trouble with their sense of touch, language, or spatial processing.
What is the Parietal Lobe?
