Histology (Cells) of the Nervous System â¢ 2 major categories of cells are found in the nervous system:â¢ 1. Nerve cells (neurons) âcarry impulses and are electrically excitable.â¢ 2. Glial cells (neuroglia)- do not carry impulses, not electrically excitable.â¢ We will discuss glial cells first.â¢ Glial Cells (Neuroglia): These cells do not carry electrical impulses as they are not electrically excitable. There are several types of glial cells with a number of different functions.
Which nerve cells do what? Two sorts of cells make up the nervous system: neurons and glial cells. Neurons are the building blocks of the nervous system. Information travels along neurons as electrical signals â nerve impulses. These signals are passed to the next neuron in the chain at special sites known as synapses. There are ten times as many glial cells than neurons. Glial cells do not actually conduct electrical impulses, they look after the structure and maintenance of the brain.
