Does a efferent neuron convey information away from the hippocampus?
Technically efferent neurons carry information AWAY from anything, afferent neurons carry information TOWARD something. So the hippocampus may have efferent information going to other parts of the brain (limbic structures, frontal lobe structures, etc). Most often efferent information refers to motor output in or to the peripheral nervous system.
Are efferent nerve fibers described as motor nerve fibers?
Yes.
What part of a spinal nerve contains only efferent fibers?
The ventral root of the spinal nerve has the efferent fibers and the dorsal root has the afferent. Prior to joining each other in the spine they each consist of only those fibers.
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.
What type of fibers make up the posterior and anterior roots of the spinal nerve?
Both Afferent and Efferentboth sensory and motorContains motor & sensory fibers!The spinal cord consists of nerve fibers that are afferent and efferent.
The efferent division of the peripheral nervous system innervates?
A muscle or a gland. Efferent fibers carry information away from the CNS to innervate tissues that perform functions; such as a gland, a smooth muscle, a skeletal muscle, or cardiac muscle. The antonym to efferent would be afferent.
DoesAfferent fibers carry messages to the muscles true or false?
False. Afferent fibers carry the messages to the brain while Efferent fibers carry them to the CNS which then goes directly to the motor unit for a reaction to the stimulus.

What is the fiber type in the dorsal root?
efferent (motor) I'm guessing it's choice B in your packet?
Are efferent nerve fibers also described as motor nerve fibers?
yes
Are efferent nerve fibers described as motor nerve fibers?
Yes.
What is the difference of efferent and aesthetic reading?
Aesthic reading is for entertainment. Efferent reading is reading to carry away information; the focus is on the information in the text and illustration and not focused on the experience of reading for entertainment.
What type of neuron carries information to the CNS?
Afferent neurons carry information to the CNS, and efferent neuron carries it away.
Are axons efferent or afferent?
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 ventral root of the spinal nerve has the efferent fibers and the dorsal root has the afferent. Prior to joining each other in the spine they each consist of only those fibers.
What are the functions of afferent and efferent nerves?
Afferent nerves carry sensory information from the body to the brain, allowing us to sense touch, temperature, pain, and other stimuli. Efferent nerves, on the other hand, transmit signals from the brain to the muscles and glands, enabling movement and physical responses.
Does the efferent system sends information from the brain to spinal cord throughout the body?
You are correct; efferent neurons carry impulses from your brain to/and spinal cord throughout the body. Efferent nerves, otherwise known as motor or effector neurons, carry nerve impulses away from the central nervous system to effectors (such as muscles or glands and also the ciliated cells of the inner ear).The term 'efferent' can also be used in more localized locations (though still in the nervous system). For example, a neuron's efferent synapse provides input to another neuron, and not vice-versa. Vice-versa would be afferent. (see below)The opposite of efferent neurons are afferent, which are neurons that carry impulses from the body back to the brain. An easy mnemonic: Efferent connections Exit. Afferent connections Arrive.Hope this helps!
