Afferent Neurons
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.
Yes, they are.
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.
Yes, sensory neurons are a type of afferent neuron. They carry information from sensory receptors to the central nervous system.
These are called efferent neurons. The one that carry impulses away are afferent. Afferent (A) are away (A).
I believe you mean autonomic neurons (part of the ANS) and yes, they can be sensory neurons. Sensory neurons are the same as afferent neurons--meaning they carry signals towards the CNS. Think as afferent as 'approaching'. Anyhow, these neurons sense the conditions of your visceral organs and whatnot. Other wise it would have no information to judge for what signals to send. So yes, autonomic neurons consist of both sensory (afferent) and motor (efferent) neurons.

afferent neurons
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.
The motor neuron is the final common pathway for all neurons to travel to complete their synapse. Afferent neurons or unipolar neurons all pass through the cord and brain on this journey.
The neurons form the bodies nervous system.
Yes, they are.
Not all efferent neurons are motor; some can be autonomic (meaning they control involuntary functions). Similarly, not all afferent neurons are sensory; some can be visceral (relaying information from internal organs). CNS neurons can include interneurons that integrate and transmit signals between sensory and motor neurons, but not all CNS neurons are interneurons, as there are also sensory and motor neurons found within the CNS.
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 :).
