Nervous tissue

 Nervous tissue

Features:
- consists of nerve cells (neurons) and glial cells (neuroglia)
- conducts nerve impulses


Neurons
- they are responsible for the main function of the nerve tissue - conduction of nerve impluses
- they perceive stimuli from the external and internal environment
- they transfer information to various organs, which allows them to control and coordinate their work
structure of a neuron
- cell body containing a cell nucleus - dendrites - numerous, short, branching appendages - axon - a single, long and branched appendage, surrounded by a myelin sheath, which shortens the conduction time of nerve impulses

The nerve impulse conducted by a nerve cell usually runs from the dendrites to the axon

Neuroglia
Support the growth and functioning of neurons: - provide neurons with nutrients - they form myelin sheaths around the axons
