Neuron Structure
This is the basic functional unit of the nervous system that transmits electrical signals.
What is a neuron?
This part of the brain connects the brain to the spinal cord.
This is an automatic response that happens without thinking.
What is a reflex?
This system breaks down food and absorbs nutrients.
What is the digestive system?
This system includes the brain and spinal cord.
What is the central nervous system (CNS)?
This part of the neuron carries impulses away from the cell body.
What is the axon?
This lobe of the brain is mainly responsible for processing visual information.
The Occipital lobe
This part of the nervous system controls fast, involuntary actions.
Answer: What is the spinal cord?
This system moves oxygen and nutrients through the body using blood.
What is the circulatory system?
This system includes all the nerves outside the brain and spinal cord.
What is the peripheral nervous system (PNS)?
These branch-like extensions receive signals from other neurons.
What are dendrites?
This structure separates the right and left hemispheres of the cerebellum.
What is the vermis?
This is the pathway a reflex takes through the nervous system.
What is a reflex arc?
This system helps you breathe in oxygen and breathe out carbon dioxide.
What is the respiratory system?
This division controls voluntary movements like walking.
What is the somatic nervous system?
This insulating covering around axons speeds up nerve impulses.
What is the myelin sheath?
This part of the brainstem acts as a bridge between different parts of the nervous system.
What is the Pons
This type of response protects the body from harm quickly.
What is a protective response?
This system supports the body and protects organs.
What is the skeletal system?
This division controls involuntary actions like heart rate and digestion.
What is the autonomic nervous system?
These gaps in the myelin sheath allow impulses to jump during saltatory conduction.
What are the Nodes of Ranvier?
This layer of gray matter covering the cerebrum is responsible for higher thinking.
What is the cerebral cortex?
This neuron carries signals from the body to the spinal cord.
What is a sensory neuron?
This system helps you move your body using muscles.
What is the muscular system?
This branch of the autonomic nervous system controls “fight or flight.”
What is the sympathetic nervous system?
