| Term | Definition |
|---|---|
| Alzheimer’s | causes a loss of gray matter in the cerebrum. |
| Axons | transmit signals |
| Blood-brain barrier | a layer of epithelial cells that prevents cells and large proteins from entering the brain. |
| Concussion | a brain injury caused by a blow to the head |
| Dendrites | receive incoming signals from other neurons. |
| Gray matter | Neuron cell bodies and dendrites. Processing occurs here. |
| Gyri | raised ridges that cover the cerebrum |
| Interneuron | transmits impulses between neurons. |
| Meninges | layers of connective tissue covering the brain. |
| Motor neuron | triggers muscle movement. |
| Myelin | a white mixture of proteins and phospholipids that coats most axons |
| Neuroglia | makes up all nervous system structures |
| Neuron | communicates with other cells and contains all of its organelles |
| Neurotransmitters | binds to receptors on the target cell, activating it. |
| Reflexes | rapid, involuntary movements that result from a nerve pathway called a reflex arc that bypasses the brain. |
| Stroke | an event that disrupts blood flow to part of the brain. |
| Sulci | grooves that cover the cerebrum |
| Synapse | The space between a neuron axon and its target cell |
| White matter | Myelinated axons. Transmission occurs here. |
