Card Set Information
PNS Epilepsy HA
Damage is proximal to distal.
Damage is distal to proximal.
Phospholipid membrane that forms the surface of the axon.
This occurs when nerves are subjected to external compression or disease.
Nerve injury that involves segmental demyelination.
Nerve injury where the axon has been damaged but the connective tissue coverings remain intact.
Nerve injury with complete severance of the axon, as well as the disruption of its supporting connective tissue coverings at the site of injury.
A single peripheral nerve is affected.
Involvement of several peripheral nerves.
Indicates involvement of the nerve root as it emerges from the spinal cord.
Indicates involvement of several nerve roots and occurs when infections create an inflammatory response.
- Inherited disorder
- Affects motor and sensory nerve
- Slow progressing disease
AKA Peronial muscle atrophy
- Hypertrophic onion bulb formation in which demyelinated axons are surrounded by Schwann cells and their processes as remyelination is attempted.
Distally symmetric muscle weakness, atrophy, and diminished DTRs.
- pes cavus
- weakness of dorsiflexors and evertors
- steppage gait
Legs takes on the shape of an inverted champagne bottle.
AKA Acute Inflammatory Demyelinating Polyradiculneuropathy
- it occurs with IDDM and NIDDM
- there is muscle atrophy
- it is a metabolic neuropathy
Chronic compression of nerves and arteries between the clavicle and the first rib is?
An acute inflammatory PNS disorder that involves the spinal nerve root to the distal termination of motor and sensory fibers is?
Bell's Palsy is the involvement of which cranial nerve?
Facial N. - VII
A process of filtering antibodies from the plasma.
A life threatening condition in which seizures are prolonged and recovery does not occur between attacks is?
- usually a good prognosis
- facial asymmetry
- sound magnification
A medication used to control epilepsy.
- nocturnal pain
- lansinating pain
- cranial nerve 5
- autoimmune disease
- weakness of skeletal muscles
- a slow progressive course
A motor end plate disorder.
Myelin of the Schwann cell is the primary target.
Surgical resection of the dorsal root of the spinal nerve.
Medial epicondylectomy and surgical nerve transplant to the anterior elbow may reduce or eliminate symptoms of?
Tardy ulnar nerve palsy
A chronic disorder of various causes characterized by recurrent seizures.
Result of paroxysmal excessive discharge of cerebral neurons resulting in transient impairment or loss of consciousness.
This can occur as a reaction of the brain to physiologic stress, sleep deprivation, fever, and alcohol or sedative drug withdrawal.
During the seizure, neurons are tonically depolarized and fire continuously in a sustained, high frequency discharge called the _____ phase.
The seizure ends as phasic repolarizations interrupt the continuous firing pattern called the _____ phase.
Gradual restoration of membrane potentials to normal or to a temporary hyperpolarized state is called?
The process that mediate long-lasting changes in brain function in response to repeated, gradually augmented stimulation of the brain resulting in epileptiform activity.
A seizure associated with preservation of consciousness and unilateral hemispheric involvement.
Simple partial seizures
A seizure associated with alteration or loss of consciousness and bilateral hemispheric involvement.
Complex partial seizures
A generalized tonic-clonic seizure that develops from either a ssimple partial or a complex partial seizure and has convulsive manifestations.
Partial seizure evolving to secondarily generalized seizures
Sudden cessation of ongoing conscious activity with only minor convulsive muscular activity or loss of postural control.
Absence seizures or petit mal seizures
Sudden, brief, single or repetitive muscle contractions involving one body part or the entire body.
Also known as "drop attacks," are brief losses of consciousness and postural tone not associated with tonic muscular contractions.
Total loss of control. Begins with a sudden loss of consciousness, and falls are common. Then generalized rigidity phase follwed by very rapid jerking movements.
Tonic-clonic seizures or grand mal seizures
- Most common type of headache
- Unilateral throbbing headache
- Anorexia, nausea, vomiting
- Can recur at either sides
- Unilateral excruciating pain headache
- Usually always the same side
- Eye and temporal area
