Neuroglia – These are special cells found in the brain and spinal cord. They provide support to the neurons and fibres. Neurosecretory Cells – These function as endocrine organs. They release chemical from the axons direcly into blood.

What is a nervous tissue?

Nervous tissue makes up the peripheral and the central nervous system. 1. It responds to stimuli and carries out communication and integration. 2. It provides electrical insulations to nerve cells and removes debris. 3. Carries messages from other neurons to the cell body.

TYPES OF NERVOUS TISSUES 1. Neurons are highly specialized nerve cells that generate and conduct nerve impulses. 2. Neuroglia are supporting cells that provide physical sport, remove debris, and provide electrical insulation.
