What is an efferent division?
The efferent or motor division transmits impulses from the CNS out to the peripheral organs to cause an effect or action. Finally, the efferent or motor division is again subdivided into the somatic nervous system and the autonomic nervous system.
What are the three efferent divisions?
The special visceral efferent fibers exit the skull through the jugular foramen with the vagus nerve and then divide into three major branches: the pharyngeal nerve, superior laryngeal nerve, and recurrent laryngeal nerve.
What is the efferent division of the PNS?
Efferent division of the PNS
The efferent division sends information from the nervous system to the organs of the body which then carry out the appropriate response. The efferent division is generally a link between the central nervous system and the effector organs so that the CNS can regulate the various responses.
What are efferent neurons quizlet?
Efferent Neuron. also called motor neurons. They carry messages from the brain and spinal cord to the muscles and glands. Associative Neuron. also called interneurons.
What is the function of the efferent pathway?
Explanation: Efferent pathways carry signals away from the central nervous system. Essentially, they are signals that your brain sends to tell your body to do something, like blinking. Afferent signals come from outside stimuli and tell your brain what they are sensing, such as temperature.
What is difference between afferent and efferent?
Afferent neurons carry information from sensory receptors of the skin and other organs to the central nervous system (i.e., brain and spinal cord), whereas efferent neurons carry motor information away from the central nervous system to the muscles and glands of the body.
What is efferent pathway quizlet?
Efferent Pathway carries out. choice or decision form the brain to the body.
What is the function of efferent nerves?
The peripheral nervous system is composed of efferent nerves, which are responsible for transmitting signals from the brain to various organs throughout the body, including bones.
What is efferent quizlet?
-axons efferent: carry impulses away from soma. In relationship to CNS. (both anatomical and functional divisions) 1)afferent is neurons carrying info towards CNS–sensory neurons. 2)efferent is neurons carrying info away from CNS–motor neurons.
What is the function of an efferent neuron?
Efferent neurons, also called motor neurons, are the nerve fibers responsible for carrying signals from the brain to the peripheral nervous system in order to initiate an action. In other words, they are the neurons that tell your body to perform an action, such as removing your hand from a hot pan.
What is the difference between afferent and efferent pathways?
Afferent neurons carry information from sensory receptors found all over the body towards the central nervous system, whereas efferent neurons carry motor information away from the central nervous system to the muscles and glands of the body in order to initiate an action.
How do you remember afferent or efferent?
Explanation: A good way to remember afferent vs. efferent neurons is: Afferent Arrives, Efferent Exits. Afferent neurons are neurons whose axons travel towards (or bringing information to) a central point, while an efferent neuron is a cell that sends an axon (or carries information) away from a central point.
What efferent means?
: conducting outward from a part or organ. specifically : conveying nervous impulses to an effector. efferent neurons. compare afferent.
What are afferent and efferent pathways quizlet?
1)afferent is neurons carrying info towards CNS–sensory neurons. 2)efferent is neurons carrying info away from CNS–motor neurons. -interneurons may be present.
What does efferent nerve mean in biology?
nerves that carry information away from the central nervous system, to the peripheral nervous system. Efferent may also be used generally to describe nerves that are leaving a nervous system structure (i.e., output fibers for a particular area as opposed to input fibers).
What is afferent and efferent quizlet?
Afferent nerves transmit impulses from the SENSORY receptors in the skin, muscles, and joints to the CNS. Efferent (motor) nerves carry impulses from the CNS out to the muscles and glands.
What is the difference between efferent and afferent?
Where is the action of efferent process?
The efferent fiber is a long process projecting far from the neuron’s body that carries nerve impulses away from the central nervous system toward the peripheral effector organs (mainly muscles and glands). A bundle of these fibers is called an efferent nerve (if it connects to muscles, then it is a motor nerve).
How do you remember afferent and efferent?
What is the difference between afferent and efferent nerves quizlet?
What is the difference between afferent and efferent nerves? Afferent nerves transmit impulses from the SENSORY receptors in the skin, muscles, and joints to the CNS. Efferent (motor) nerves carry impulses from the CNS out to the muscles and glands.
Whats the difference between afferent and efferent?

What is another word for efferent?
In this page you can discover 9 synonyms, antonyms, idiomatic expressions, and related words for efferent, like: motor nerve, afferent, motorial, efferent nerve, gabaergic, effectors, brainstem, thalamic and thalamus.
Where is the afferent neuron located?
dorsal root ganglion
Afferent neurons have a unique structure that differs from most other neurons. Their cell bodies are located just outside of the spinal cord in the dorsal root ganglion.
What is efferent nerve with example?
The efferent nerves are nerves that carry nerve impulses away from the central nervous system. They carry the impulses to muscles and organs. Motor nerves, which are made up of a chain of motor neurons, are efferent nerves. They originate in the spinal cord and innervate muscles.
