What spinal segment structure carries non-myelinated GVE fibers?
The white ramus communicans carries non-myelinated GVE fibers.
Sympathetic nerves may leave the spinal cord at which vertebra?
Preganglionic sympathetic axons leave the spinal cord throughout the thoracic spine and the upper lumber spine (T1-L2).These preganglionic sympathetic axons exit the spinal canal within the anterior primary ramus and then quickly separate to travel via the white ramus communicans to the ipsilateral sympathetic trunk.
Compare the color of the dorsal and ventral surfaces on the fish?
Frogs usually have a dark green or brown dorsal color and a white or yellowish ventral color. This helps them blend in with the water surface from above and the water surface from below as well giving protection from underwater and above water predators.
Does the white rami communicans contain fibers of a preganglionic or postganglionic neurons?
Preganglionic because they are myelinated. FALSE
Describe the color of the sorsal and ventral surfaces of the frog?
A frog is a tailless amphibian, having a short squat body and very long hind legs for leaping. The color of the dorsal surface is green while the ventral surface is off-white.
What part of the spinal cord contains neurons?
Motor neurons are located in the gray matter of the brain, and their axons stretch out to the spinal cord through the ventral root. they are located in the Ventral horn of the spinal cord,
What is the color of the green sea turtle?
greenAnother AnswerA green sea turtle is a dark green on the dorsal side (back) and a light cream or white color on the ventral side (bottom).
Whats the colour difference between frogs ventral and dorsal side?
It helps them camouflage itself from predators. Although the answer above is true, here is a more informative answer. The bottom of the frog is a lighter color then the top. This is because if the frog is floating on top of the water, and prey or a predator looks up and the frog, the suns glare makes the frog harder to see. Also, there are darker splotches on the bottom so it doesn't show the silhouette for the frog. the top of the frog is darker because when swimming at the bottom of a murky lake, it blends in with the bottom.
What does an eastern barred bandicoot look like?
An eastern barred bandicoot has a pointed snout and large ears. Its dorsal (back) fur is dark brown, and its ventral (belly) fur is white. Two white stripes extend onto the dorsal surface, going horizontally, near the base of the tail. Its head-and-body length is about twelve and a half inches, and its tail length is about three and a half inches.
Does a great white dorsal fin always stay upright?
A great white dorsal fin does always stay upright in the water. The fin is what helps the shark swim.
Gray rami communicantes connect to what two structures?
White rami communicantes (sing. ramus communicans) are literally white branches of communication between each spinal nerve and the sympathetic trunk. Their color is white because these lines of communication contain mainly myelinated nerve fibers of pre-ganglionic general visceral efferents from the spinal cord. Many of the pre-ganglionic nerve fibers synapse at the corresponding spinal segment level, and thus build a sympathetic ganglion at that level. Other pre-ganglionic white fibers either ascend or descend in the sympathetic trunk before synapsing in sympathetic ganglia above or below the spinal segment of origin. The sympathetic ganglia are literally knots in the sympathetic cord primarily containing cell bodies of the post-ganglionic neurons, whose axons are unmyelinated and gray in color. These unmyelinated post-ganglionic nerve fibers rejoin the spinal nerve at that level via the gray rami communicantes,as well as ascending or descending to adjacent levels. The white rami may also contain lightly myelinated sympathetic afferents whose cell bodies in the dorsal root ganglia synapse in the dorsal horn gray of the spinal cord. ANSWER: Carry preganglionic axons to the sympathetic chain
The white matter tract in the ventral portion of the mid-brain?
spinothalamic tract
