Axons and dendrites extend from the cell and form the white matter of the brain]]> 2017-10-31 12:59:11 UTC https://padlet.com/ajj8119/m2pd6wnfcpyi/wish/202105326 ajj8119 https://padlet.com/ajj8119/m2pd6wnfcpyi/wish/202106906 Dendrites are finger like branches that bring signals to the brain, axons carry signals away from the brain eg. When you feel stimuli in your finger (ie. heat) the sensory impulse sends message to the brain and back to your fingers to process the impulse to move.]]> 2017-10-31 13:02:23 UTC https://padlet.com/ajj8119/m2pd6wnfcpyi/wish/202106906 ajj8119 https://padlet.com/ajj8119/m2pd6wnfcpyi/wish/202109119 Glial cells replicate throughout life, unlike the nerve cell. There are four types: astrocytes, oligodendrocytes, ependymal cells and microglia. They bind and insulate neurones and some are PHAGOCYTIC - protect from bacterial invasion by binding blood vessels to the neurones]]> 2017-10-31 13:06:35 UTC https://padlet.com/ajj8119/m2pd6wnfcpyi/wish/202109119 ajj8119 https://padlet.com/ajj8119/m2pd6wnfcpyi/wish/202111428 The Axon of many neurones are coated with a protective fatty layer called the myelin sheath. It insulates axons and enhances transmission of impulses]]> 2017-10-31 13:10:57 UTC https://padlet.com/ajj8119/m2pd6wnfcpyi/wish/202111428 ajj8119 https://padlet.com/ajj8119/m2pd6wnfcpyi/wish/202112426 Nervous tissue is the most vital part of the nervous system which comprises the spinal cord, brain and peripheral nervous system.
