GLASGOW COMA SCALE

The nervous system is an organ system containing a network of specialized cells called neurons that coordinate the actions of a human being and transmit signals between different parts of its body. The nervous system consists of two parts, central and peripheral. The central nervous system contains the brain, spinal cord, and retina. The peripheral nervous system consists of sensory neurons, clusters of neurons called ganglia, and nerves connecting them to each other and to the central nervous system.

Neuron– is the functional unit of the nervous system. Each connected at the synapse between axon (transmits message away from the neuron) and dendrite (transmits message towards the neuron.
Neurotransmitters– are chemical compounds which activate or inhibit such transmission.

NEUROLOGICAL ASSESSMENT CONSISTS OF THE FF:
