Scientists have organized the cells that make up the nervous system into two broad groups: neurons, which are the primary signaling cells, and glia, which support neurons in various ways. The human brain contains around 100 billion neurons and, by most estimates, somewhere between 10 to 50 times as many glial cells. Bipolar ones are usually found outside the brain and interneurons are found within the brain.
most of the neurons in the brain and spinal cord are
interneurons also called central or association neurons
Signals are transmitted through the spinal cord and brain via neurons.
Sensory neurons
No, neurons in the brain include interneurons as well as sensory neurons and motor neurons. Interneurons primarily communicate with other neurons in the central nervous system, while sensory neurons carry information from sensory organs to the brain and spinal cord, and motor neurons transmit signals from the brain and spinal cord to muscles and glands.
Sensory neurons gather information and send it to your spinal cord.
afferent neurons
The sensory neurons carry impulses through the spinal cord to the brain.
Sensory neurons
In CNS i.e. in spinal chord and in brain
Interneurons send messages from the spinal cord to the brain.
Motor or efferent neurons.
