Brain Parts
This part of the brain controls balance and coordination.
Cerebellum
These cells carry messages throughout the body.
Neurons
This system controls voluntary actions
Somatic nervous system
This disease causes memory loss and confusion, usually in older adults.
Alzheimer's disease
The basic unit of the nervous system.
Neuron
This lobe of the brain is responsible for vision
Occipital Lobe
This covering protects axons and speeds up signals.
Myelin sheath
This system controls involuntary actions.
Autonomic nervous
What are the four brain diseases
Epilepsy, concussion, Ischemic stroke and, Alzheimer's disease.
A bundle of nerve fibers is called this
Nerve
This part of the brain controls breathing and heart rate
Medulla oblongata
These cells form the myelin sheath in the peripheral nervous system.
Schwann cells
The brain and spinal cord make up this system.
Central nervous system
What is the cause of Ischemic stroke
Blood clot in the brain
Chemicals that carry signals between neurons are called this
Neurotransmitters
This is the largest part of the brain
Cerebrum
The gap between two neurons is called this.
Synapse
Nerves outside the brain and spinal cord belong to this system
Peripheral nervous system
what brain injury is often caused by a blow to the head and can lead to headaches, dizziness, and confusion
Concussion
This is the long extension that carries impulses away from the cell body
Axon
This structure connects the left and right hemispheres of the the brain.
Corpus callosum
During an action potential, this process allows sodium ions to rapidly enter the neuron.
Depolarization
This part of the autonomic nervous system is responsible for increasing heart rate, dilating pupils, and slowing digestion during stress
Sympathetic nervous system
This disorder is caused by abnormal electrical activity in the brain.
Epilepsy
This type of neuroglia in the central nervous system forms myelin around axons
Oligodendrocytes
