What type of nerve fibers are found in the ventral ramus of a spinal nerve?
Both sensory and motor
What is the term for nerves carrying both sensory and motor fibers?
Nerves carrying both sensory and motor fibers are called sensorimotor nerves.
What is the fiber type in the dorsal root?
efferent (motor) I'm guessing it's choice B in your packet?
Sensory and motor fibers in th skin are located in the?
dermis
Does a mixed nerve contain both sensory and motor neurons?
Yes, "Mixed nerves" of the peripheral nervous system contain both sensory and motor fibers
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 do the mixed cranial nerves containing both motor and sensory fibers include?
Olfactory
What is the main function of interneuron?
interneurons are located in the brain and spinal cord. They are stimulated by signals reaching them from sensory neurons. they process that information and send a response through the motor neurons.
What type of nerves fibers make of each of the following sensory nerves?
Well, there are really only three types of fibers, but they all have different sub-classes to them. A, B, and C. A and B fibers are myelinated, and C fibers are unmyelinated. A fibers are broken down further by conduction velocity into 4 main groups, alpha, beta, gamma, and delta. In general a chart of these fibers would look something like this..A(alpha), largest and fastest velocity, acts as motor and sensory fibersA(beta), next largest, acts as motor and sensory.A(gama), next largest, acts as motor only.A(delta), next largest, acts as sensory only.B, smaller than A fibers, only acts a motor.C, smallest, acts as motor and sensory. In general, the A class of fibers are related to muscles(extrafusal and intrafusal fibers), A(delta) sensory fibers relay touch, pressure, pain, and temp, B motor fibers are for the autonomic system, while C sensory fibers are also for pain and temp. Note. Sometimes the sensory fibers are classified by a roman numeral system from I to IV. They are the same fibers, just numbered differently. They look like this... A(alpha) = IaA(alpha) = IbA(beta) = IIA(delta) = IIIC = IV Hope this helps...Daniel {| |- | A 1-20 5-120 0.3-0.5 B
What is the network of the sensory and motor nerves?
The network of sensory and motor nerves together is called the peripheral nervous system.
Are dorsal and ventral roots spinal nerves?
The ventral roots contains motor fibers, responsible for motion, whereas the dorsal sensory fibers, responsible for touch and feeling.
Spinal nerve contains both motor and sensory nerve fibers for 2-way communications?
yes
