Overview and Functions
This system controls and communicates all activities in the body.
The Nervous System.
This system includes the brain and spinal cord.
The central nervous system.
This organ is the main control center of the body.
The brain.
This is the basic unit of the nervous system.
A neuron.
This disease causes memory loss and confusion, usually an older adults.
Alzheimer’s Disease.
These are the three main parts that make up with the nervous system.
The brain, spinal cord, and nerves.
This system includes all nerves outside the brain and spinal cord.
The peripheral nervous system.
This part of the brain controls balance and coordination.
The cerebellum.
These parts of a neuron receive signals from other neurons.
Dendrites.
This disease causes shaking and slow movement.
Parkinson’s Disease.
The nervous system uses these two types of signals to send messages.
Electrical and chemical signals.
This division of the PNS controls voluntary movements like walking.
Somatic nervous system.
This part of the brain controls thinking, memory, and voluntary movement.
The cerebrum.
These parts of the neuron send signals away from the cell body.
The axon.
This is one cause of nervous system disorders that can be passed down in families.
Genetics.
This is what the nervous system maintains by keeping things like temperature and heart rate stable.
Homeostasis.
This division controls “fight or flight” responses like increased heart rate.
Sympathetic division.
This lobe of the brain is responsible for vision.
The occipital lobe.
This is the small gap between neurons where signals are passed.
The synapse.
This is one way to keep the nervous system healthy by helping the brain rest and repair.
Getting enough sleep.
Name the three main functions of the nervous system.
Sensory input, integration, and motor output.
This part of the nervous system acts as the main control center and processes information.
The central nervous system.
This structure carries messages between the brain and the rest of the body and controls reflexes.
The spinal cord.
These are the three types of neurons in the body.
Sensory, motor, and interneurons.
These are two careers that study the nervous system and behavior.
Neurologists and psychologist.
