Classification of Neurons
Based on classification of neuron by structure and function, neurons can be classified into different types. Some of them are:
Neurons Classification based on Function
- Sensory neurons, or Afferent neurons: These conduct impulses from the sensory receptors to the CNS.
- Motor neurons, or Efferent neurons: These conduct impulses from the CNS to the effectors.
Neurons Classified by Structure
According to the number of processes of neurons, they are divided as
- Unipolar Neurons: These show a single process bifurcating into a dendrite and an axon. These are produced by the fusion of two processes of original bipolar neurons. E.g., Cells of the dorsal route Ganglia.
- Bipolar Neurons: Bipolar neurons have one axon and one dendrite. E.g., Bipolar cells of the retina and olfactory mucosa.
- Multipolar Neurons: Multipolar neurons have one axon and multiple dendrites. The majority of neurons in the CNS are multipolar.
Neuron Structure and Function
Neurons in human body are the constituents of the nervous system. The neuron diagram shows that they are elongated, and specialized for transmitting electric signals throughout the body. The structure of a neuron consists of a cell body and dendrites. The neurons join together to form the Nervous tissue. The function of neurons is to generate and transmit electric impulses throughout the body. In this article, we will discuss the neuron diagram, meaning, neuron structure, the classification and types of neurons, and neuron function.
