Neurotransmission (transfer of message across nervous system) occurs all over the body, the signal or message passed from tissues to brain and brain to body tissues in response via different neurons.

What The two types of cells of the nervous system are?
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.
What are the three classes of neuron?
The three classes of neurons are sensory neurons, motor neurons, and interneurons. Sensory neurons transmit sensory information from sensory organs to the central nervous system (CNS), motor neurons carry signals from the CNS to muscles and glands to control movements, and interneurons facilitate communication between sensory and motor neurons within the CNS.
Does the sensory afferent division conveys impulses away from the central nervous system?
No, the sensory afferent division conveys impulses towards the central nervous system. Afferent neurons transmit sensory signals from sensory receptors to the central nervous system, whereas efferent neurons carry signals away from the central nervous system to muscles and glands.
Neurons that carry impulses away from the central nervous system?
Neurons that carry impulses away from the central nervous system are called motor neurons. They transmit signals from the brain and spinal cord to muscles or glands, allowing for voluntary and involuntary movements to occur.
Three differences between sensory neurone and motor neurone?
Sensory neurons receive sensory input from the environment and transmit this information to the central nervous system, while motor neurons transmit signals from the central nervous system to the muscles and glands. Sensory neurons have a cell body located outside the central nervous system (in the dorsal root ganglia), while motor neurons have their cell bodies located within the central nervous system (in the spinal cord or brainstem). Sensory neurons are usually unipolar, with a single process extending from the cell body, while motor neurons are typically multipolar, with multiple processes extending from the cell body.
Similarities of motor and sensory neurons?
Sensory neurones carry impulses to the CNS, motor neurones carry impulses to muscles.

What carries impulses toward the neuron cell body?
Sensory neurons, also known as Afferent neurons carry information toward the CNS.
When a group of neurons that carry impulses from the CNS to effectors are clustered together they are called what?
Motor neurons.

Sensory neurons transmit sensory information from sensory organs to the central nervous system (CNS), motor neurons carry signals from the CNS to muscles and glands to control movements, and interneurons facilitate communication between sensory and motor neurons within the CNS.

What type of neuron carries information to the CNS?
Sensory neurons, also known as afferent neurons, carry information from sensory receptors to the central nervous system (CNS). These neurons transmit information about external stimuli (such as touch, sound, and light) or internal conditions (such as pain or temperature) to the brain and spinal cord.
Three differences between sensory neurone and motor neurone?
Sensory neurons receive sensory input from the environment and transmit this information to the central nervous system, while motor neurons transmit signals from the central nervous system to the muscles and glands. Sensory neurons have a cell body located outside the central nervous system (in the dorsal root ganglia), while motor neurons have their cell bodies located within the central nervous system (in the spinal cord or brainstem). Sensory neurons are usually unipolar, with a single process extending from the cell body, while motor neurons are typically multipolar, with multiple processes extending from the cell body.
What Nerve to the brain triggers pain?
Afferent nerves carry impulses to the CNS (central nervous system: brain/spinal chord).
Why are motor neurons also known as efferent neurons?
Motor neurons are also known as efferent neurons because they carry signals from the central nervous system to muscles and glands, leading to an outward response or action. These neurons control voluntary movements as well as involuntary actions like heartbeat and digestion.
Why sensory neurons are called as afferent neurons?
Sensory neurons are called afferent neurons because they carry information from sensory receptors to the central nervous system. "Afferent" means to carry inward, referring to the direction of information flow towards the central nervous system.
