the common peroneal nerve and the tibial nerve:
The nerve that approaches the knee and divides into the fibular and tibial nerves is the sciatic nerve, which is the largest nerve in the body. It originates from the lower spine and travels down the back of the thigh, eventually splitting into these two branches at the knee.
The two branches of the sciatic nerve are the tibial nerve and the common fibular (peroneal) nerve. The tibial nerve supplies the posterior compartment of the leg, while the common fibular nerve innervates the anterior and lateral compartments of the leg and the muscles of the foot.
The sciatic nerve is the largest and longest single nerve in the human body, about as big around as a thumb at its largest point. The nerve originates in the lower spine as nerve roots exit the spinal cord (through the bones in the spine), and extends all the way down the back of the leg to the toes. The sciatic nerve is actually a combination of nerves. It is formed on the right and left hand side of the lower spine by the combination of the fourth and fifth lumbar nerves and the first three nerves in the sacral spine. Each nerve exits the spine between two vertebral segments and is named for the segment above it.
(Sciatica is a condition involving pain, weakness, numbness, or tingling in the leg. It is caused by an injury to or compression of the sciatic nerve which branches down your back.The sciatic nerve is commonly injured by fractures of the pelvis, gunshot wounds, or other trauma to the buttocks or thigh. Prolonged sitting or lying with pressure on the buttocks may also injure it. )The sciatic nerve is the longest nerve in your body; it runs from your lower back, through your buttock, down your leg.The tibial and fibular nerves originate from spinal segments L4-S3. The two nerves come together and are referred to jointly as the sciatic (meaning hip) nerve. The sciatic nerve is the largest peripheral nerve in the body.They separate at the back of the knee. The tibial nerve supplies the posterior compartment of the leg and the fibular supplies the anterior and lateral compartments.The sciatic nerve are nerve roots coming out of the spinal cord and into the lower back.
The "sciatic nerve" are actually a pair of nerves, one to the left leg and one to the right. They exit the spine in the lumbar region. The nerves tend to get inflamed by the muscles or spinal compression with pain radiating down the affected leg. Miserable....
The only two cranial nerves that are completely sensory are the olfactory nerve (I) for smell and the optic nerve (II) for vision.
too close to the sciatic nerve
The olfactory bulbs [I] and the optic nerve [II]
the spinal nerves "receives" the nerve impulses from the rest of the body while the cranial nerves "process" these nerve impulses.
nerves are white tough and string like structure there r two types of nerves sensory nerve and motor nerve neuron.............. neuron is basic unit of structure and function of nervous system ..........brain spinal cord and nerves are made up of neurons
The vagus nerve and the glossopharyngeal nerve are two main nerves that run up the neck and into the ear. The vagus nerve supplies the outer ear and the auricle. The glossopharyngeal nerve provides sensation to the middle ear.
