Erb's palsy is a paralysis of the arm caused by injury to the upper group of the arm's main nerves, specifically the severing of the upper trunk C5–C6 nerves. These form part of the brachial plexus, comprising the ventral rami of spinal nerves C5–C8 and thoracic nerve T1. [1][2][3] These injuries arise most commonly, but not exclusively ...
The nerve point of the neck, also known as Erb's point, [1] is a site at the upper trunk of the brachial plexus located 2–3 cm above the clavicle. It is named for Wilhelm Heinrich Erb. [2] Taken together, there are six types of nerves that meet at this point. "Erb's point" is also a term used in head and neck surgery to describe the point on ...
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
Klumpke's paralysis is a variety of partial palsy of the lower roots of the brachial plexus. [1][2] The brachial plexus is a network of spinal nerves that originates in the back of the neck, extends through the axilla (armpit), and gives rise to nerves to the upper limb. [3][4][5][6] The paralytic condition is named after Augusta Déjerine ...
Palsy. Palsy is a medical term which refers to various types of paralysis [1] or paresis, often accompanied by weakness and the loss of feeling and uncontrolled body movements such as shaking. The word originates from the Anglo-Norman paralisie, parleisie et al., from the accusative form of Latin paralysis, from Ancient Greek παράλυσις ...
Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy (chemotherapy-induced peripheral neuropathy).
Trochlear nerve palsy also affects torsion (rotation of the eyeball in the plane of the face). Torsion is a normal response to tilting the head sideways. The eyes automatically rotate in an equal and opposite direction, so that the orientation of the environment remains unchanged—vertical things remain vertical.
Patients with neurocysticercosis and arachnoiditis may present with focal signs and ischaemic strokes caused by small and medium intracranial artery occlusion, cranial nerve entrapment resulting in extraocular muscle paralysis, hearing loss, facial nerve palsy or trigeminal neuralgia, and focal neurological symptoms caused by brainstem compromise.
