What is a benefit of a nerve plexus?
A plexus is a branching network of axons outside of the central nervous system. The four primary nerve plexuses are the cervical plexus, brachial plexus, lumbar plexus, and the sacral plexus. The choroid plexus is a part of central nervous system in the brain and it consist of capillaries, ventricles and ependymal cells. source of this information : Wikipedia.
Is the posterior interosseous nerve a cranial nerve or a spinal nerve?
what does ninth cranial nerve control? glossopharyngeal nerve is a mixed nerve, it has sensory and motor part. the sensory is at the poserior 1/3 of the tongue. It also is part of the pharyngeal plexus. (9,10,11) The motor part of the nerve ONLY supply the stylopharyngeus muscle!
Which nerve plexus contains the femoral nerve?
The femoral nerve is part of the lumbar plexus. It arises from the anterior divisions of the L2 to L4 spinal nerves. The lumbar plexus mostly innervates the lower limb muscles and skin.
What are the two primary nerve plexuses regulating digestive function?
The two primary nerve plexuses regulating digestive function are the myenteric plexus (Auerbach's plexus) and the submucosal plexus (Meissner's plexus). They are part of the enteric nervous system and play important roles in controlling gastrointestinal motility, secretion, and blood flow.
Ventral rami of spinal nerves C1 through T1 and T12 through S4 take part in forming?
Except for T2-T12, all ventral rami branch and join one another lateral to the vertebral column, forming complicated interlacing nerve networks called nerve plexuses. Nerve plexuses occur in the cervical, brachial, lumbar, and sacral regions and primarily serve the limbs (MarieB, 2010 8th ed. pp. 502)
What neuropathy can be diagnoised by emg?
EMG is part of an electrodiagnostic examination that involves both nerve conduction studies (NCS) & needle EMG (nEMG).An electrodiagnostic examination may diagnose many things, including:A lesion of the nerve root as it exits the spinal column, called a radiculopathy.A lesion of a nerve plexus, such as the brachial plexus, lumbar plexus, or the lumbosacral plexus.A lesion of a peripheral nerve. The most common peripheral nerve lesion is the median nerve at the wrist, seen in carpal tunnel syndrome. Other peripheral nerve lesions commonly seen include the ulnar nerve at the elbow, the ulnar nerve at the wrist, the peroneal nerve at the knee, the tibial nerve at the ankle, and many more.A polyneuropathy affecting many nerves may be diagnosed. An example of this would be a diabetic axonopathy or a hereditary demyelinating polyneuropathy. There are many, many different types of polyneuropahty.A myopathy or muscle disease.
What major nerves arise from the sacral?
The nerves that arise from the lumbar plexus are femoral, obturator, lateral femoral cutaneous, genitofemoral, illoinguinal and illohypogastric nerve. As part of lumbosacral plexus, it is the nervous plexus that is found in the lumbar region.
What structures are found in the anticubital area near the basilic nerve?
This fossa is an important clinical area because it contains the biceps tendon, the brachial artery and its terminal branches (radial and ulnar arteries), the brachial veins, and part of the median and radial nerves.it contains the biceps tendon, the brachial artery and its terminal branches (radial and ulnar arteries), the brachial veins, and part of the median and radial nerves.
What are the submucosal plexus and myenteric plexus?
The submucosal plexus (Meissner's plexus) is a network of nerve fibers found in the submucosa of the gastrointestinal tract that helps regulate glandular secretion and local blood flow. The myenteric plexus (Auerbach's plexus) is located between the circular and longitudinal muscle layers of the gastrointestinal tract and is responsible for controlling gastrointestinal motility. Both plexuses are part of the enteric nervous system, often referred to as the "second brain" of the body.
In the gastrointestinal tract where is myenteric plexus?
in wall of GIT the muscularis layer is composed of longitudinal and circuler fibers and the myentric nerve which is the part of enteric nervoius system is present between the longitudinal and circuler fibers
Where is the solar plexus?
The reason they use "solar" is because it refers to radiating, like the sun does. In the abdomen there is a group of radiating nerve fibers, or "plexus", that are situated behind the stomach and in front of the aorta. So they refer to the radiating quality of this group of nerves as solar plexus.
Which part of the body does the term brachial refer?
Brachial (as in brachial artery) refers to the upper limbs, the arms.
