Sensory Input
The function of the nervous system that involves gathering information from sensory receptors.
Integration
The processing of information by the nervous system to determine responses.
Motor Output
The response of the nervous system to stimuli, often resulting in movement.
Homeostasis
The process by which the nervous system regulates body functions such as heart rate and temperature.
Central Nervous System (CNS)
Consists of the brain and spinal cord.
Peripheral Nervous System (PNS)
Includes all the nerves outside the CNS that connect it to the rest of the body.
Sympathetic Division
Part of the autonomic nervous system that prepares the body for 'fight or flight' responses.
Parasympathetic Division
Part of the autonomic nervous system that promotes 'rest and digest' functions.
Neuroglia
Support cells in the nervous system that nourish, protect, and assist neurons.
Astrocytes
CNS neuroglia that maintain the blood-brain barrier and provide structural support.
Oligodendrocytes
CNS neuroglia that produce myelin to insulate CNS neurons.
Microglia
CNS immune cells that remove waste and pathogens.
Ependymal Cells
CNS cells that line brain ventricles and help circulate cerebrospinal fluid (CSF).
Schwann Cells
PNS neuroglia that produce myelin for PNS neurons.
Satellite Cells
PNS neuroglia that support and protect neuron cell bodies in ganglia.
Myelin Sheath
Insulating layer around axons that increases the speed of electrical signal transmission.
Neurotransmitters
Chemical messengers that transmit signals across synapses between neurons.
Synapse
The gap between two neurons where signal transmission occurs.
Excitatory Neurotransmitters
Neurotransmitters that increase the likelihood of an action potential.
Inhibitory Neurotransmitters
Neurotransmitters that decrease the likelihood of an action potential.
