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.
What else can I help you with?
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 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.
Carries impulses between spinal cord and body parts?
CENTRAL
What are the afferent and efferent fibers for Pretectal nucleus of the midbrain?
It receives its afferent light impulses from the retina and occipital cortex.it gives efferents to the Edinger-Westphal nuclei of both sides.
What is the fiber type in the dorsal root?
The fiber type in the dorsal root is mainly composed of sensory nerve fibers that transmit sensory information from the periphery to the central nervous system. It is made up of both Aδ fibers responsible for transmitting sharp, well-localized pain and touch sensations, and C fibers responsible for transmitting dull, diffuse pain and temperature sensations.
Which one of the cerebellar peduncles that contains afferent fibers only?
It's the middle cerebellar peduncle.As for superior cerebellar and inferior cerebellar peduncles, they are both contain afferent and efferent fibres.
DoesAfferent fibers carry messages to the muscles true or false?
False. Afferent fibers carry sensory information from the peripheral nerves to the central nervous system, such as information about touch, pain, temperature, etc. Efferent fibers, on the other hand, carry signals from the central nervous system to the muscles to initiate movement.
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.
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 type of nerves are spinal nerves Are they Afferent Efferent or Mixed?
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.
Are efferent nerve fibers described as motor nerve fibers?
Yes, efferent nerve fibers are often described as motor nerve fibers. Efferent nerves carry signals away from the central nervous system to muscles and glands, controlling movement and bodily functions.
What neuron fibers are running through the CNS?
In the central nervous system (CNS), there are two main types of neuron fibers: afferent (sensory) fibers that carry information from sensory receptors to the CNS, and efferent (motor) fibers that carry information from the CNS to effectors such as muscles and glands. These fibers make up the vast network of connections that allow for communication within the brain and spinal cord.
