CNS consists of kezdjen tanulni		the brain and the spinal cord.
PNS consists of kezdjen tanulni		nerves that carry sensory messages to the CNS and motor commands from the CNS to the muscles and glands.
Two types of cells are: kezdjen tanulni		neurons and neuroglia.
Neurons funtions are to: kezdjen tanulni		transmit nerve impulses between parts of the nervous system.
Neuroglia functions are to: kezdjen tanulni		support and nourish neurons, maintain homeostasis, form myelin and may aid in signal transmission.
Neurons consist of: kezdjen tanulni		a cell body, dendrites and an axon.
The cell body contains kezdjen tanulni		the nucleus and other organelle.
Dendrites are kezdjen tanulni		extensions leading toward the cell body that receive signals from other neurons.
An axon function is to: kezdjen tanulni		conducts nerve impulses away from the cell body toward other neurons or effectors.
Different sorts of neurons are: kezdjen tanulni		sensory neurons, interneurons and motor neurons.
A sensory neuron function is to: kezdjen tanulni		take messages to the CNS.
A sensory neuron may be equipped with: kezdjen tanulni		endings called sensory receptors that detect changes in the environment.
An interneuron lies kezdjen tanulni		within the CNS.
An interneuron function is to: kezdjen tanulni		receive input from sensory neurons and from other interneurons. Sum up all the messages received from sensory neurons before communicate with motor neurons.
A motor neuron function is to: kezdjen tanulni		take messages away from the CNS to an effector.
