The document discusses the nervous system and two neurological suffixes: -algesia and -taxia. -Algesia refers to pain or sensitivity, such as hyperalgesia which is heightened sensitivity to pain that can be caused by infection or damage to nerves. -Taxia refers to muscle coordination; ataxia is a lack of coordination that can be hereditary or caused by damage to the nervous system's movement and balance control centers, resulting in impaired mobility, balance, and fine motor skills.

2. Neurological suffixes
 The nervous system
deals with the
coordination of the
body. Sensory input
flows to the brain where
it is analyzed. A
response is then
created and sent out.
 -algesia
pain, sensitivity
 -taxia
Innervations of body organs
muscle coordination

3. Hyperalgesia
•Heightened sensitivity to pain
• In cases of infection: body’s
inflammatory response-
cytokines-is exacerbated.
•Localized or widespread
•Connected to fibromyalgia
• widespread achiness of soft
tissue and muscles
•Damage to nerves can also
trigger increased feelings of pain
Pain pathways

4. Ataxia
•Lacking coordination or without
coordination
•Degenerative neurological condition
•Movement and balance control
centers of nervous system have been
affected resulting in limb, speech,
and visual impairment.
•Can refer to either the symptoms of
incoordination or degenerative
condition of the central nervous
system.

5. Ataxia symptoms
•Adult onset is typical, but can be
in range of 20-60.
• Balance and coordination
• Limb coordination, slurred
speech.
• Impaired mobility, patient will
compensate by bowing legs
• Fine motor skills that require
grasping ability become
impaired
• Hereditary ataxia-genetic
disorder
• Can be fatal if patient is bound
to bed and their. ability to
swallow affects respiration
