| Question | Answer |
|---|---|
| Nervous system | helps maintain homeostasis, responsible for: mental processes, behaviors, emotional reponses |
| 3 Neuron structures | Dendrites (branches) brings info in for sensory, afferent; cell body(soma)has nucleus, axon (singular process)take info away from the cell motor, efferent |
| Synapse means together or join; 3 targets (effectors)Figure 6-2 page 160 | 1. neuron 2. muscle 3. gland |
| Functions of Nervous system | sensory function: receptors detect stimuli and respond by sending information to the CNS; intergration function: CNS integrates this information and decides on a response; motor function: motor neurons carry impulses from the CNS to the muslces and glands |
| Central nervous sytem | Incased in bone and protected by meninges and cerebral fluid, has brain (in skull) and spinal cord (in vertebral column) |
| Spinal cord has how many pairs of spinal nerves (page 161 figure 6-4) | 31 pairs of spinal nerves |
| cervical has how many bones and how many nerves | 7 bones and 8 nerves |
| Brain structure (page 161 figure 6-5) | brainstem, cerebellus, diencephalon, cerebrum |
| brainstem | midbrain, pons, medulla oblongata |
| Diencephalon | thalamus, pineal body, hypothalamus |
| Cerebrum | cortex and corpus callosum |
| Peripheral nervous system (2 parts) | Somatic nervous system (volutary); automonic nervous system (involuntary) divided into parasympathetic and sympathetic nervous systems. |
| parasympathetic (page 163 figure 6-7) | rest and digest |
| sympathetic (page 163 figure 6-7) | fight or flight |
| CNS disorders | cerebral palsy, spina bifida, seizure disorders, spinal cord injury, |
| Cerebral palsy | group of motor disorders; damage to cerebrum from inadequate or reduced blood flow; lighter pressure; avoid joint mobilizations or administer carefully; instruct parents to massage in affected person is a child. |
| 2 types of cerebral palsy | lack of cordnation either spastic or flaccid |
| spina bifida | group of neural tube defects; failure of posterior spinous processes to close (usually lumbar spine); local contraindication; avoid joint mobilizations and compressions or admiister carefully; instruct parents to massage if affected person is a child |
| Three types of spina bifida | occulta, meningocele, myelomeningocele |
| Seizure disorders | explosive episode of uncontrolled and excessive electrical activity in the brain; 2 types partial: limited to single area of brain and Generalized: more diffuse involvement. postpone massage if condition is untreated; avoid known triggers |
| spinal cord injury | damage to the vertebrae and neural tissues causing loss of movement and loss of sensation distal to area of insult--paraplegia:paralysis of the lower extrmities and trunk--quardriplegia:paralysis of the trunk and all extremities |
| ADHD attention deficit-hyperactivity disorder | array of behaviors associtaed with inattentiveness, hyperactivity, impulsivity, or combination of these; reduce treatment time; instruct parents to massage if affected person is a child |
| Autism | syndrome of social withdrawal and obsessive behavior; five types ranging from mild and highly functional to severe. Reduce treatment time, use firm gliding and compressive strokes |
| Infectious diseases | meningitis, encephalitis, poliomyelitis and postpolio syndrome |
| meningitis | inflammation of the meninges most often the result of a viral or bacterial infection, massage is contraindicated until client completely recovers |
| encephalitis | inflammation of the brain, fever, head ache and stiff |
| poliomyelitis | highly contagious viral infection that is now rare, massage contraindicated until client completely recovers |
| postpolio syndrom | collection of symptoms seen in individuals who have previously recovered from polio or who were misdiagnosed, but now considered to have been infected, light massage cautiously apply stretches |
| Neurodegenerative disease | dementia, alzheimer disease, huntington disease, Parkinson disease (paralysis agitans); multiple sclerosis |
| Dementia | group of disorders characterized by a decline of mental facilities and personalyity changes that interfere with work, social activities; tow most common types are Alzheimer and vascular, gentle massage |
| alzheimer disease | progressive degenerative disease of the brain, gentle massage shorter duration |
| huntington disease | inherited disorder characterized by motor disturbances, mental deterioration, and abnormal behavior; light massage of shorter duration; cautiously apply passive stretches |
| parkinson disease | disorder producting abnormal movements marked by destruction of dopamine producing neurons in the brain, gentle massage and shorter duration. |
| multiple sclerosis (autoimmune) | progressive neural demyelination, massage contraindicated during flare-ups; otherwise gentle massage of shorter duration (parestesia altered sensation) |
| Amyotrophic lateral sclerosis (Lou gehrig's disease) | degeneration of motor neurons leading to secondary demyelination; this causes generalized paralysis leaving the affected person immoblie, gentle massage of shorter duration |
| vascular disorders | cerebrovascular accident (stroke), transient ischemic attack, migrain headache |
| Trasient Ischemic attack | brief episode of impaired brain functioning caused by temporary reduction of blood flow; lasts a few seconds to possbily hours and is characterized by slurred speech |
| Cerebrovascular accident (stroke) | sudden disruption in cerebral blood flow by occluded or ruptured blood vessel; obtain medical clearance during rehab stage |
| Stroke Warnings | sudden weakness, numbness, or tingling in face, arm or leg; temporaray loss of speech, failure to comprehend; sudden loss of vision; sudden severe headache; unusual dizziness or loss of balance |
| migrain headache (vascular headache) | severe, recurrent headaches accompanied by symptoms such as visual disturbances and nausea; often provoked by a trigger factor; massage is contraindicated during attack |
| Peripheral never disorders | Trigeminal neuralgia, bell palsy, myasthenia gravis, guillain-Barre Syndrome, |
| Trigeminal neuralgia (Tic douloureux)3 branches Ophthalmic branch, maxillary branch, mandibular branch | condition characterized by excruciating episodic pain in areas supplied by the trigeminal nerve (cranial nerve); avoid prone position and avoid massage to the face and scalp. |
| Bell's Palsy (#7 nerve) | condition of facial nerve causing muscle weakness or paralysis on one side of face; use light gliding strokes directed upward, and kneading, percussion, and vibration on facial muscles. |
| Myasthenia Gravis (muslce, weakness) | disorder caused by loss of acetylcholine receptors within the neuromuscular junction resulting in progressive weakness and paralysis; gentle massage of shorter duration |
| Acetylcholine; dopamine | makes the muscles more more;makes muscles go down. |
| Guillan-Barre Syndrome (peripheral nerves) | neurologic inflammatory disease of the peripheral nerves; typically begins as leg weakness and ascends to trunk and arms; Massage is contraindiated |
| Peripheral Neuropathy (diabetics) | inflammation or degeneration of PNS causing symptoms of impaired sensations and movement difficulties; reduced pressure while avoiding hypersensitive areas; if neuropathy in lower extermities, avoid bolster use. |
| Paresthesia | abnormal feelings |
| degenerative disc disease | deterioration of the intervertebral discs resulting from teh aging process or accident; medical clearance required, once obtained, reduce pressure over affected areas and avoid spinal mobilizations |
