|
Neurons |
Specialized cells transmitting nerve impulses. Each has branches like a tree |
|
|
Nerves |
Bundles of Neurons; pathways that transmit electrochemical signals from one part of your body to the other. |
|
|
Central Nervous System (CNS) |
Made up of your brain and the spinal cord; responsible for analyzing and interpreting all data collected and sent by the peripheral nervous system. |
|
|
Peripheral Nervous System (PNS) |
Collects and sends data to the CNS of everything and, after it has been processed and decides for the data, it receives instructions back from it and carries it out into action. |
|
|
Afferent Neurons |
Carries things TO the central point |
|
|
Efferent Neurons |
Carries things AWAY from the central point |
|
|
Somatic Nervous system |
Part of the Efferent Nervous system; controls all the information coming through your senses and the movement of your body |
|
|
Reflex loop |
A neural pathway that controls an action reflex |
|
|
Autonomic Nervous system |
Also part of the Efferent Nervous system; carries signals from the central nervous system that drives all unconscious actions (ex. breathing, heartbeat) |
|
|
Sympathetic division |
Part of the autonomic nervous system; wants to take control of the body. It is responsible for situations such as stress. (Flight or fight response). It also prepares the body for action. |
|
|
Parasympathetic division |
Also part of the autonomic nervous system and wants to take control of the body. It keeps the body calm and under control. |
|
|
Homeostasis |
When the sympathetic division and the parasympathetic division works together to form a balance |
|
|
Saltatory conduction |
The hopping of the signals from node to node, letting it travel down the nerve faster |
|
|
Synapses |
The place where an axon of a neuron's branches come in contact with the next cell's dendrite (Also where neurotransmitters pass information from one neuron to the other |
|
|
Membrane potential |
A difference in voltage, or electrical charge, between the inside and the outside of the membrane. |
