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.
The three basic types of nerve cells are motor neurons, sensory neurons and interneurons. A motor neuron is a cell that transmits a signal to a muscle or gland.Sensory neurons receive information from sensory organs and transmit that information back to the central nervous system.he three basic types of nerve cells are motor neurons, sensory neurons and interneurons.
