the peripheal nervous system
Sensory nerves are called afferent nerves, and motor nerves are called efferent nerves. Afferent nerves carry sensory information from the body to the central nervous system, while efferent nerves carry signals from the central nervous system to the muscles and glands to initiate a response.
Efferent means going away from and afferent is going toward. The afferent arteriole of the kidney carrys blood toward the glomerulus, whereas the efferent arteriole carrys blood away from the glomerulus.
They can be both. Afferent axons carry (sensory) information toward the central nervous system; efferent axons carry (motor command) information away from the central nervous system towards the muscles and glands. Think "affect" vs. "effect" or "arrive" vs. "exit".
Spinal nerves are mixed nerves, meaning they contain both afferent (sensory) and efferent (motor) nerve fibers. This allows them to transmit both sensory information from the body to the central nervous system and motor commands from the central nervous system to the body.
opposite of an afferent neuron. an efferent neuron goes from the central nervous system to the organ in the body that will perform the required action.
· Afferent and efferent divisions are:o Sensory (afferent) Division§ Somatic afferent nerves - carry impulses from skin, skeletal muscles, and joints to the CNS§ Visceral afferent nerves - transmit impulses from visceral organs to the CNSo Motor (efferent) Division§ Transmits impulses from the CNS to effector organs, muscles and glands, to effect (bring about) a motor responseAfferent nerves are the one that carry the information from periphery to central nervous system for further processing. While efferent nerves carry the processed information from central nervous system towards the periphery for action.

Sensory nerves are called afferent nerves, and motor nerves are called efferent nerves. Afferent nerves carry sensory information from the body to the central nervous system, while efferent nerves carry signals from the central nervous system to the muscles and glands to initiate a response.
Efferent means going away from and afferent is going toward. The afferent arteriole of the kidney carrys blood toward the glomerulus, whereas the efferent arteriole carrys blood away from the glomerulus.
they don't have a difference Unless you are talking about the direction of their signal. Afferent is taking information toward the central nervous system while efferent is taking information away from the central nervous system.
Afferent pathways communicate sensory information (e.g. pain, cold) from your sensory organs to your central nervous system. Efferent pathways communicate information from your central nervous system to your effector organs (e.g. muscles and glands).
Impulses traveling to the thalamus are afferent. Afferent pathways carry sensory information from the peripheral nervous system to the central nervous system, including the thalamus, for processing. Efferent pathways, on the other hand, carry motor commands from the central nervous system to the peripheral nervous system for action.
They can be both. Afferent axons carry (sensory) information toward the central nervous system; efferent axons carry (motor command) information away from the central nervous system towards the muscles and glands. Think "affect" vs. "effect" or "arrive" vs. "exit".
The major difference is the direction of travel for nerve impulses. In the afferent nervous system, the impulses are traveling away from the brain - these tend to be motor impulses. In the efferent nervous system, the impulses are traveling towards the brain - these tend to be sensory impulses.
A motor neuron is an efferent neuron as it 'sends out' a signal as opposed to sensory nerves which are afferent and relay information from the periphery towards the central nervous system.
Afferent refers to pathways leading to the cortex (ie, sensory). Efferent are pathways leading away (ie, motor). You are *affected* by a situation, you *effect* change on someone else.
The peripheral nervous system is made up of the sensory (afferent) and motor (efferent) divisions. The motor division is furthermore split into the somatic and autonomic nervous systems. Lastly, the autonomic nervous system is split into the sympathetic (fight or flight) and parasympathetic (rest and digest) nervous systems.
