Does the sciatic nerve pass through the lesser sciatic foeamen?
If you look up the nervous system there are 3 places in your lower back that cause Sciatic or pinched nerve in three locations. Lower lumbar back at 3,4,5, cause pain in the left or right backside cheek, a shorter nerve. One causes pain that comes into the groin are from the backside around and up through groin. One causes the pain that runs down the outside seem of your pants and can end of in the second little toe. (next to the pinkie toe) It is called the Sciatic nerve.
Anatomy and Health Issues Related to the Sciatic Nerve?
The "sciatic nerve" (pronounced "sigh + attic") is the longest nerve in the human body. It provides sensory communication between the brain and most of the buttocks and legs. This sensory communication goes in both directions, and includes pain messages that travel from the legs to the brain, as well as information on how to move the leg that travels from the brain to the muscles in the leg. Five separate nerves from the upper body combine to form the sciatic nerve. These nerves, known as S1, S2, S3, L4 and L5, come together in the upper part of the buttocks. From there, small nerve branches emerge and provide sensory communication to the hip joint. The main strand extends down the back of the leg to the knee, where it splits again into separate strands. The "tibial" strand continues down the back the leg and "innervates," or provides sensory perception and communication for, the heel and sole of the foot. The "peroneal" strand travels around the outside of the knee, down the side of the leg, and innervates the front part of the lower leg and the upper part of the foot. The largest segment of the nerve is the size of a person's thumb. The most common health problem associated with the sciatic nerve is known as "sciatica." Sciatica occurs when the S, L, or main sciatic nerve branches are compressed or pinched. Symptoms for sciatica include pain, numbness, tingling, weak muscles or movement difficulties in the lower back, buttocks, legs or feet. Spinal disc herniation is one common cause of sciatica. It may result from twisting and bending motions, which place unusual stress on the soft material inside the vertebrae. These movements may cause the soft material to rupture, spilling fluids into the narrow opening that allows the nerves to pass through the vertebrae, thus causing inflammation that compresses the nerve. Another common cause of sciatica is "piriformis syndrome." In most people, the sciatic nerve is below the piriformis muscle, a muscle in the buttocks region. However, in some people, the nerve passes through that muscle. When that muscle is compressed, the sciatic nerve is also compressed. Piriformis compression can be caused by something as simple as a large wallet in a hip pocket.
Which artery and nerve pass through the lateral triangular space?
The radial nerve and the profunda brachii artery pass through the lateral triangular space.
What area of the os coxae do the nerves pass through to the perineum?
Lesser sciatic notch Rationale: The lesser sciatic notch area of the os coxae is where the nerves pass through to the perineum. The perineum is defined as the surface region in both males and females between the pubic symphysis and the coccyx (pelvic floor).
Why do you get muscle spasms?
Muscle spasm are caused by due to hyper or hypo stimulation of the peripheral nerves which in turn decrease or increase the action.
What are the routes followed by nerve impulses as they pass through the nervous system?
Nerve pathways
Which nerves pass through the jugular foramen?
The nerves which passes through the jugular foramen are: glossopharyngeal nerve(IX), vagus nerve(X) and accessory nerve(XI).
What muscle does the esophagus pass through to reach the stomach?
The lower esophageal sphincter muscle/the cardiac sphincter muscle.
What is autonomic motor neurons?
a nerve cell forming part of a pathway along which impulses pass from the brain or spinal cord to a muscle or gland.
Does muscle tissue conduct nerve impulses from one neuron to another and coordinates body activity?
Muscle tissue cannot conduct nerve impulses from one neuron to the other. Moreover, skeletal muscle tissue cannot even pass impulses between themselves and they should be stimulated by single branches of neurons. However, cardiac muscle cells has the unique ability to conduct impulses between themselves through gap junctions.
What structure pass through the adductor subsartorial canal?
femoral artery and femoral vein, saphenous nerve and nerve to vastus medialis
What cranial nerve doesn't pass through the thalamus?
CN 1 does not pass thru, from what I read. It's the only one.
