The two types of cells in the CNS are neurons and glia. There are many types of glia, including oligodendrocytes, astrocytes, and microglia, each with different functions. In general, glia support neuronal function.
in the CNS
Efferent neurons (sometimes called motor neurons) transmit signals from the CNS to the effector cells.
Nerve cells specialized on transmitting messages from one part of the body to another. Motor neurons send information away from the central nervous system (CNS). Sensory neurons send information toward the CNS. Inter-neurons send information between motor and sensory neurons.
Neurons or the nerve cells are the basic unit of nervous system. Based on their function (as in whether they transmit impulse from the CNS or to the CNS) neurons are classified as sensory neurons (carry impulses to the CNS), motor neurons (carry impulses from the CNS to the target organ) and mixed neurons which perform both the functions. The neurons can also be classified based on the number of associated axons or even presence or absences of axons.
Nerve cells (neurons) of the CNS (i.e. the brain).

You don't, but glial cells, (oligodendrocytes in the CNS, and Schwann cells in the PNS), wrapped one after another around the axons of neurons with gaps between them called the nodes of Ravnier do create myelinated neurons.

Sensory neurons: Transmit sensory information from the body to the brain. Motor neurons: Control muscles and glands, enabling movement and bodily functions. Interneurons: Process information within the central nervous system, facilitating communication between sensory and motor neurons.

CNS = Oligodendrocytes PNS = Schwann cells
Functional types of neurons: 1. sensory (afferent) neurons - input to CNS from sensory receptors; dendrites located at receptors, axons in nerves, cell bodies in ganglia outside the CNS 2. motor (efferent) neurons - output from CNS to effectors cell bodies and dendrites located in the CNS, axons in nerves 3. interneurons - communicate and integrate information within the CNS; located entirely within the CNS
