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.
What part of the peripheral nervous system carries the sensory and motor information to and from the central nervous system?
You have thousands of nerves that are part of the PNS.Divisions of the peripheral nervous system include the afferent (sensory) division and the efferent (motor) division. The nerves coming from all the senses and the nerves going to glands and muscles are included.The efferent division is divided further into the somatic motor nervous system and thesomatic nervous system which includes all voluntary motor pathways outside the central nervous system.
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 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 division transmits impulses from the cns to the muscles or glands?
The sensory or afferent division of the peripheral nervous system transmits impulses from the sense organs to the CNS.
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.
Are effernet nerve fibers described as motor nerve fibers?
Yes, remember the mnemonic SAME DAVESAME DAVE:sensory is afferent, motor is efferentdorsal is afferent, ventral is efferent
What is the fiber type in the dorsal root?
efferent (motor) I'm guessing it's choice B in your packet?

What do the terms afferent and efferent mean?
· 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.
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).

What division transmits impulses from the cns to the muscles or glands?
The sensory or afferent division of the peripheral nervous system transmits impulses from the sense organs to the CNS.
What is the difference between afferent and efferent nerve fibers?
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.
Which fibers carry action potential to cause skeletal muscles to contract?
Alpha motor neurons
