These neurons are classified by the direction in which they send their messages. Afferent neurons are typically sensory neurons--neurons which send information to the brain and spine. They send information about the body and immediate environment. Efferent neurons are typically motor neurons, sending information from the brain and spine to the rest of the body. They allow the main control system a way to act on the body. Another way to distinguish these two is to think of afferent nerves as 'approaching' the brain (A) and efferent nerves as 'exiting' the brain (E). Interneurons are relay neurons and their signals, connecting efferent and afferent neurons in network. They can link up the same types or different types of neurons, meaning connecting sensory neurons together, motor neurons together, or the different types together. The simplest example of these three types working in unison is a reflex arc (which is what is activated when you hurt yourself, like stepping on a pin or burning your hand). The sensory/afferent neuron detects pain and signals the interneuron. Simultaneously, the interneuron sends a signal to your efferent/motor neurons to retract your hand/leg/whatever, while also sending a message to the brain. This is why you pull back before you feel pain :).

What neurons receive messages about what is happening inside and outside the body?
efferent and afferent neurons
What neurons that carry impulse to the brain and spinal cord called?
These are called efferent neurons. The one that carry impulses away are afferent. Afferent (A) are away (A).
Neurons are categorized by?
Structure Unipolar Bipolar Multipolar AND FUNCTION sensory or afferent neurons Motor or efferent neurons
Where is the neuron?
The Inter-neuron (also known as the local circuit neuron, relay neuron or the association neuron) is the neuron which connects the afferent and the efferent neurons in the neural pathways.
What type of neuron is also called an interneurn because it carries messages between the other two types of neurons Associative Afferent Efferent?
The type of neuron that is also known as an interneuron is the associative neuron. Interneurons are responsible for transmitting signals between sensory neurons (afferent neurons) and motor neurons (efferent neurons) in the central nervous system.
Does the autonomic nervous system use a two efferent neuron chain or a two afferent chain?
two efferent neurons
What nerve is carrying the afferent and efferent impulses during the patellar reflex?
The nerves innervate the quadriceps. The afferent nerves are the muscle spindles and the efferent are the motor neurons.
What connects to sensory neurons?
You have three neurons in the reflex arc. You have the afferent, the intermediate and efferent neurons in the reflex arc. So the answer is intermediate neuron.
What afferent neurons convey information?
Afferent neurons carry sensory information in the form of nerve impulses to the central nervous system. Efferent/motor neurons carry commands to effectors such as muscles and glands.
In a three neuron reflex arc the afferent neurons synapse with?
In a three neuron reflex arc, the afferent neurons synapse with interneurons in the spinal cord or brainstem. The interneurons then synapse with efferent neurons which transmit the signal to the effector organ to initiate a response.
What neuron connects an afferent neuron to an efferent neuron?
The interneuron acts as a connector between afferent and efferent neurons in the central nervous system. It integrates and processes incoming sensory information before transmitting signals to the efferent neuron to produce a response.
What is. The function of associative neurons?
The neurons form the bodies nervous system.
