A) white rami connunicans\n\nRemember that thoracic and lumbar regions are for the sympathetic chain ganglion.

You are referring to the upper part of the trapezius and the levator scapula.\n\nShrugs hit it pretty directly.  Rowing exercises are also a great way to use the mid and lower fibers a bit more.

It is the peripheral nervous system.  It is a system of nerves that are outside the brain and spinal cord (the ones that extend into your arms and legs and into your chest and abdomen).

It is called pyriformis syndrome - the muscle over the sciatic nerve (deeo in the buttocks area) is aggravating the scaitic nerve and causing pain itself.\n\nLook of on web MD pyriformis syndrome - it will show you stretchs that help.

Spinal\n\n\n\nErection is basically a spinal reflex that can be initiated by recruitment of penile afferents, but also by visual, olfactory, and imaginary stimuli. The reflex involves both autonomic and somatic efferents and is modulated by supraspinal influences. Several central transmitters involved in the erectile control have been identified. Dopamine, acetylcholine, nitric oxide (NO), and peptides, such as oxytocin and adrenocorticotropic/alpha-melanocyte-stimulating hormone, seem to have a facilitatory role, whereas serotonin may be either facilitatory or inhibitory, and enkephalins are inhibitory.

It depends on what is pinching the nerve. Is it bone or muscle or disc. and at which level it is getting compressed and for how long. and what procedure has been under taken to relieve the nerve. and what is your general body health. and what is the extent of injury meanse does it only compressed for a day and showing the sighn of compression only like pain and tingling or its got a cut. Please First provide all this details including your age

You could have a trapped nerve or a myriad of other conditions...you really should go to see your doctor.

Reflexes and pain travel on different neuronal pathways. Reflexes involve motor nerves and pain involves sensory nerves. Pain receptors, also known as nociceptors, depend on where the injury occured. Nociceptors are in your skin. If you have an internal injury, you won't feel pain.

The ligamentum nuchae is that well-developed portion of the supraspinous ligament in the cervical region. It runs from the external occipital protuberance along the tips of the spinous processes of the cervical vertebrae, to the tip of the spinous process of the vertebra prominens (usually C7). The supraspinous ligament can be considered the superficial continuation of the interspinous ligament. This latter ligament runs between the adjacent vertebrae extending from the base to the tip of each spinous process. The ligamentum nuchae is formed primarily from the aponeurotic attachments of the adjacent and subjacent musculature. From superficial to deep, these muscles are the trapezius; rhomboideus minor; splenius capitis; and the serratus posterior superior.

Go to a chiropractor. I have carpal tunnel syndrome, tennis elbow, had sciatica during pregnancy, and plantar fasciitis in the foot. All symptoms of pinched nerves somewhere. The chiropractor will adjust your spine, neck, wrist or whatever (go for a full adjustment) hurts. The body works as a whole system and not separate systems of skeletal, muscular and nervous systems acting independently. The chiropractor adjusts the bones so that the nerves will not be pinched anywhere, and will massage the muscles which have built up lactic acid causing a lot of tension. You will need a few adjustments initially. He/she will pop your neck and spine, but don't do this on your own, because some people do this sudden twisting of their necks to relieve tension. That's dangerous. \n\nTell the chiropractor all your physical aches and pains. If you are in Toronto I can give you the name of my chiropractors, a brother-sister team who are really great chiropractics and utterly wonderful people!  I would rather see them than a regular doctor who will give you a fast prescription rather than holistic treatment.

it's a nerve thing alright, but probably not in your elbow . . the nerve stretches up and back to your shoulder blade and probably it's your posture and work habbit at the computer . . . if you go to a doctor they can't do anything except try to aleviate [sp] the pain . . . \n\nyoga or stretching is a very good thing . . . a physical therapist or massuse (legit one) is also a really good recomendation . . .\n\nto relieve a pinched or pressed nerve you need to remove the tension in your muscles and figure out a way to reposition your body placement.  \n\nHeated yoga (yoga in a heated room)  a very warm bath with epsom salts.  A massage, stretching and if you can be inclined it would be a good idea to do some sort of daily excersize (doesn't have to be anything extreme, even a walk for an hour)  \n\nAnd if you really want to get into it do some local research and see if you can find an Alexander Technique teacher.  It's a body movement and control technique mainly used for actors and dancers . . but the process is just a familiararity of the body and obtaining full awareness & control of it.

Depends on the reflex. Myotatic is the simplest. One synapse.\n\nAfferent Ia axon (originating in a muscle spindle) enters the spinal cord and synapses on an alpha motor neuron innervating the same muscle, causing it to fire. This reflex mediates the "knee-jerk" your doctor checks for.\n\nhttp://academic.uofs.edu/faculty/kosmahle1/courses/pt351/lect351/reflxarc.JPG\n\nExample in picture form.

A neuromuscular junction is the synapse or junction of the axon terminal of a motoneuron with the motor end plate, the highly-excitable region of muscle fiber plasma membrane responsible for initiation of action potentials across the muscle's surface, ultimately causing the muscle to contract. The signal passes through the neuromusclar junction via the neurotransmitter acetylcholine.
