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