|
|
In the neurons, electricity runs |
From the dendrite Through the cell To the axon Out to the synapse |
|
|
Neurotransmitters |
Handles communication through synapses Are chemicals that regulate different systems such as muscle movement and recognition of pain |
|
|
Central nervous system |
Consists of brain and spinal cord |
|
|
Peripheral nervous system |
All nerves outside of brain and spinal cord Divided into somatic nervous system and autonomic nervous system |
|
|
Somatic nervous system |
Contains sensory and motor nerves |
|
|
Autonomic nervous system |
Controls automatic bodily functions Divided into sympathetic nervous system and parasympathetic system |
|
|
Sympathetic nervous system |
Readies us for emergencies |
|
|
Parasympathetic system |
Operates to calm us after emergency |
|
|
Endocrine system |
Uses hormones to provide a method of chemical communications longer lasting than that provided by neurons |
|
|
Pituitary gland |
Master gland Guides growth Signals thyroid for metabolism Signal adrenal glands for emergencies Signals gonads for sexual activity |
|
|
Prefrontal area |
Involved in personal memories |
|
|
Frontal association area |
Integrates environment and carries on complex analyses |
|
|
Dendrites |
Short Fibres like tree Receive info from nerves and send it to axon |
|
|
Axon |
Long fibre Message from cell to other neurons |
|
|
Space between axon and dendrites |
Synapse |
|
|
Vesicles |
Small bubbles between synapse and axon Communication helper |
|
|
Neurotransmitters |
They transmit nerve information from one end of axon, over the synapse to the dendrite receptor |
|
|
