Test- Disorders

-Affects both the motor cortex of the brain and the motor neurons associated with voluntary muscle

• –Degenerative:
• 100% fatal
• Muscle of chest no longer receive impulse to contract/expand ~ makes breathing difficult

• –Symptoms show up at 50+
• Death in 2-3 yrs after symptoms display

(Stephen Hawking)

• –Viral disease caused by direct exposure; highly contagious
• Inflammation & destruction of spinal neurons

• –Incubation time (5-35+ days)
• Mild cold symptoms (diarrhea, vomiting, headache)
• Severe cold symptoms (increased fever, accompanied by acute muscle pains or inability to lift legs or head when lying down

• –Treatments
• Vaccine – developed in the 1950s by Dr. Jonas Salk

• –Genetic disorder
• Dystrophin absent in the cytoskeleton of the muscle fiber

• -Degenerative
• Can affect adults, however most severe forms appear early in life

• -Results in loss of function (weakness & fatigue)
• Atrophy or wasting

• -No cure
• P/T to control symptoms
• Use of mobility assistance devices
• MUST remain active

Overactive osteoclasts remove calcium from bone.

Spaces and canals appear, weakening bones.

Vitamin D deficiency

Characterized by bowed legs

Lateral bend of the vertebral column

Vertebrae fail to join at the midline during development

Degenerative deterioration of articular cartilage & spur formation usually 60+

Sodium urate crystals deposited in articular cartilage - destroys join tissue

• Degenerative autoimmune disease
• Immune system attacks joint tissue
• Inflammation of synovial membrane
• Usually age 20-50

Meds to reduce pain, anti-inflammatories, slow progression of disease

Bacteria carried by a tick

Causes stiffness, fever, chills, nausea, arthritis-like symptoms

Pressure on the median nerve as it passes through the carpel tunnel in wrist

Pain

Weakened ligaments & tendons of foot

Can't support weight well for long periods of walking
