Sensory neurones carry electrical signals - nerve impulses - towards the central nervous system (spinal cord and brain). The signal starts in a receptor which detects a change. Relay neurones...

Neurons lie adjacent to each other but are not connected. There is a tiny gap between neurons called a synapse. The function of a neuron is to transmit nerve impulses along the length of an individual neuron and across the synapse into the next neuron. The electrical signals transmitted by neurons are called action potentials. The electrical signal...
The neuron contains the soma (cell body), which extends the axon (a nerve fiber conducting electrical impulses away from the soma), and dendrites (tree-like structures that receive signals from other neurons). The myelin sheathis an insulating layer that forms around the axon and allows nerve impulses to transmit more rapidly along the axon. Neuron...
Although there are billions of neurons and vast variations, neurons can be classified into three basic groups depending on their function: sensory neurons (long dendrites and short axons), motor neurons (short dendrites and long axons), and relay neurons (short dendrites and short or long axons).

In vertebrates, the majority of neurons belong to the central nervous system, but some reside in peripheral ganglia, and many sensory neurons are situated in sensory organs such as the retina and cochlea.
Feb 28, 2022 · While there are billions of neurons and thousands of varieties of neurons, they can be classified into three basic groups based on function. These are motor neurons, sensory neurons, and...
Sep 1, 2024 · Neurons are located in the brain and spinal cord, which are organs of the CNS. Neurons are also located throughout the rest of the body in the PNS.
Jul 18, 2023 · Neurons, sometimes called nerve cells, make up around 10 percent of the brain; the rest consists of glial cells and astrocytes that support and nourish neurons.
Nov 3, 2023 · There are two types of neurons, named according to whether they send an electrical signal towards or away from the CNS; Efferent neurons ( motor or descending) send neural impulses from the CNS to the peripheral tissues , instructing them how to function.
