Paresthesias of the hands, feet, legs, and arms are common transient symptoms. The briefest electric shock type of paresthesia can be caused by tweaking the ulnar nerve near the elbow; this phenomenon is colloquially known as bumping one's "funny bone". Similar brief shocks can be experienced when any other nerve is tweaked (e.g. a pinched neck ...
Hypoesthesia is one of the negative sensory symptoms associated with cutaneous sensory disorder (CSD). In this condition, patients have abnormal disagreeable skin sensations that can be due to increased nervous system activity (stinging, itching or burning) or decreased nervous system activity (numbness or hypoesthesia).
Inferior alveolar nerve block (abbreviated to IANB, and also termed inferior alveolar nerve anesthesia or inferior dental block) is a nerve block technique which induces anesthesia (numbness) in the areas of the mouth and face innervated by one of the inferior alveolar nerves which are paired on the left and right side.
Several nondental nerves are usually anesthetized during an inferior alveolar block. The mental nerve, which supplies cutaneous innervation to the anterior lip and chin, is a distal branch of the inferior alveolar nerve. When the inferior alveolar nerve is blocked, the mental nerve is blocked also, resulting in a numb lip and chin.
The infraorbital nerve provides sensory innervation to the skin of the lower eyelid, [2] the side of the nose, [2] the moveable part of nasal septum, [citation needed] the anterior cheek, [citation needed] and part of the upper lip. [2] It does not provide motor supply to any muscles. [citation needed]
Notalgia paresthetica is a common localized itch, affecting mainly the area between the shoulder blades (especially the T2–T6 dermatomes) but occasionally with a more widespread distribution, involving the shoulders, back, and upper chest.
The superficial branches run beneath the skin and above the superficial muscles of the face, which they supply: some are distributed to the procerus, joining at the medial angle of the orbit with the infratrochlear and nasociliary branches of the ophthalmic.
Its fibers converge, to be inserted into the muscular substance of the upper lip between the angular head and the levator anguli oris. The lateral fibers, forming the zygomatic head (also known as the zygomaticus minor muscle [ 3 ] ) arise from the malar surface of the zygomatic bone immediately behind the zygomaticomaxillary suture and pass ...
