Question | Answer |
---|---|
Central Nervous System | consists of the brain and the spinal cord. |
Peripheral Nervous System | consists of millions of nerve cells that communicate with the central nervous system. |
Brain | acts as the command center for the body. |
Cerebrospinal Fluid | acts like a cushion and shock absorber for the brain and the spinal cord. |
Cerebrum | one of three distinct part of the brain; largest part of the brain; has two hemispheres and four lobes. |
Cerebellum | located underneath the cerebrum; receives orders from the frontal lobes and sends messages to the muscles throughout the body. |
Brain Stem | located below the cerebrum and in front of the cerebellum; connects brain to spinal cord. |
Spinal Cord | main pathway of information connecting the brain to the rest of the body. |
Lobe | a distinct area of the cerebrum. |
Neuron | a nerve cell that carries impulses between various parts of the body. |
Sensory Neurons | carry messages to he brain. |
Motor Neurons | send messages from the brain. |
Dendrite | receives messages from another neuron. |
Impulse | message. |
Axon | sends the impulse on to the next neuron. |
Synapse | a little gap between each neuron. |
Somatic Nervous System | controls the skeletal muscle movements. |
Autonomic Nervous System | controls involuntary activities. |
Reflexes | an action that happens before the brain has time to think about the action. |
Senses | allows us to interpret the sensory information that is gathered;hearing, sight, taste, smell, touch. |
Dermis | inner layer of the skin. |
Epidermis | outer layer of the skin. |
Memory | the ability to remember. |
Short-term memory | stores information temporarily. |
Long-term memory | can store information for a very long time. |
REM | Rapid Eye Movement; helps develop brain. |
EEG | Electroenceplalograph;to study how the brain works. |
Hormones | chemical messengers. |
Endocrine Glands | special group of cells that make and release the hormones for the body. |
Target Cells | specific group of cells affected by hormones. |
Hypothalamus | group of special cells near the base of the brain. |
Pituitary Gland | produces hormones that control other glands in the endocrine system. |
Epilepsy | occurs when the neurons in the brain send thier electrical impulses too quickly and at an irregular rate. |
Multiple Sclerosis | destroys the myelin coating that covers the axon in some neurons. |
Parkinson's Disease | causes damage to certain brain cells that control movement. |
Alzheimer's Disease | destroys brain cells; affect thinking processes. |
