what is the dorsal ganglion?
596971
Afferent (sensory) nerves originate from the dorsal (back) horn. They are classified as pseudounipolar cells and the cell body of the neuron is a bit farther from the dendrites. The dorsal root ganglion is a collection of the cell bodies for the sensory pseudounipolar cells. All sensory nerves have ganglia.

vaginal nerve\nn.\n\nAny of several nerves passing from the uterovaginal plexus to the vagina,\n\nYou really need a biology lesson before you go anywhere near a female!!!!!!!!!

Interesting. The brain is a bundle of neurons, but it has no "feeling" itself.  An electrode inserted into the brain is painless.

its a nerve but see a doctor specializing in nerves or skin to be sure.

The dorsal fin is the part that the shark has above the surface of the water.

I had a very stubborn ganglion that would not respond to aspiration, immobilization or surgery.  After the 3rd surgery, it finally was gone for good and I haven't had any re-occurance for the last 20 years.  They put some kind of special mesh covering over my wrist bones that made the cyst unable to grow back.

A group of nerve cell bodies deep inside the cerebellum; plays a role in the control of skilled, rapid movement.

Palmaris Longus muscle (one in each arm) and Epithalamus are two things that currently have no known function in the human body.  In the 1890 there were several other parts which had unknown functions but those functions have since been discovered.  These include thalamus, tonsils, male nipples, body hair, wisdom teeth, eye lashes, eye brows, ear muscles and pineal gland.  Some also argued that the pinky finger has no function in humans.

During muscle contraction the strands of collagen are stretched as the muscle shortens. This stretching deforms the terminals of the Ib afferent axon, opening stretch-sensitive cation channels. As a result, the axon is depolarized and fires nerve impulses up to the central nervous system via the spinal cord. The action potential frequency signals the force being developed within the muscle.\n\nThis sensory feedback plays an important role in spinal reflexes and in the central control of muscle contraction. Specifically, it is postulated that because a Golgi tendon organ exists in serial connection with muscle fibers, it can measure the tension that each muscle contraction builds up. The Ib afferent axon synapses with interneurons within the spinal cord and also relays information to the brain. One of the main spinal reflexes receiving an input from the Ib afferent is the autogenic inhibition reflex, which is involved with the regulation of the force profile of on-going muscle contractions.\n\nThe ascending pathways to the cerebellum are the dorsal and ventral spinocerebellar tracts and are involved in the cerebellar regulation of movement.

Sympathetic nerves originate inside the vertebral column, toward the middle of the spinal cord in the intermediolateral cell column (or lateral horn), beginning at the first thoracic segment of the spinal cord and extending into the second or third lumbar segments\n\nWhile an oversimplification, it is said that the parasympathetic system acts in a reciprocal manner to the effects of the sympathetic nervous system; in fact, in some tissues innervated by both systems, the effects are synergistic. The three main types of muscarinic receptors that are well characterised are:\n\nThe M1 muscarinic receptors are located in the neural system. \nThe M2 muscarinic receptors are located in the heart, and act to bring the heart back to normal after the actions of the sympathetic nervous system: slowing down the heart rate, reducing contractile forces of the atrial cardiac muscle, and reducing conduction velocity of the atrioventricular node (AV node). Note, they have no effect on the contractile forces of the ventricular muscle. \nThe M3 muscarinic receptors are located at many places in the body, such as the smooth muscles of the blood vessels, as well as the lungs, which means that they cause vasoconstriction and bronchoconstriction. They are also in the smooth muscles of the gastrointestinal tract (GIT), which help in increasing intestinal motility and dilating sphincters. The M3 receptors are also located in many glands that help to stimulate secretion in salivary glands and other glands of the body.

The Dorsal Aortæ.—In front of the third aortic arches the dorsal aortæ persist and form the continuations of the internal carotid arteries; these arteries pass to the brain and each divides into an anterior and a posterior branch, the former giving off the ophthalmic and the anterior and middle cerebral arteries, while the latter turns back and joins the cerebral part of the vertebral artery. Behind the third arch the right dorsal aorta disappears as far as the point where the two dorsal aortæ fuse to form the descending aorta. The part of the left dorsal aorta between the third and fourth arches disappears, while the remainder persists to form the descending part of the arch of the aorta. A constriction, the aortic isthmus, is sometimes seen in the aorta between the origin of the left subclavian and the attachment of the ductus arteriosus

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).

Simple: Our skin has sensory nerves =)

Efferent (motor) neurons appear how nerve cells are typically drawn - short dendrites and a long axon. Almost all efferent nerve cell bodies are located in the central nervous system (the brain and spinal cord).  Motor neurons conduct signals from your brain to cause muscles to move, so this makes a kind of sense.\n\nAfferent (sensory) nerves are structured oppositely - they have long dendrites and a short axon. Almost all afferent cell bodies are located in the peripheral nervous system.  These are cells that detect various sensory inputs and relay the signals through your central nervous system to your brain.
