Nervous System Anatomy & Aging
The central nervous system includes these 2 body parts
Brain and spinal cord
This disorder is caused by abnormal electrical discharges in the brain resulting in seizures
Epilepsy
The main function of the heart
Pump blood throughout the body
A chronic medical condition in which the blood pressure in the arteries is elevated
Hypertension
Provide the framework for the body and protect internal organs
Bones
A break in the bone
Fracture
The organ that helps us make sense of the outside world
Brain
This occurs when blood supply to the brain is deficient due to a blood clot or a ruptured blood vessel
Cerebrovascular accident (stroke)
Vessels that carry oxygenated blood away from the heart and to organs and tissues
Arteries
The most common symptom of a myocardial infarction (heart attack)
Angina (chest pain)
The point where two bones come together to allow movement
Joint
Condition in which bones thin and lose strength as they age
Osteoporosis
The peripheral nervous system is made up of these tiny structures that carry messages to and from the brain
Nerves
A slow, progressive neurological disorder in which there is a degeneration in part of the brain leading to muscle rigidity and mobility problems
Parkinson's disease
Vessels that carry deoxygenated blood back to the heart
Veins
A condition in which the heart is too weak to pump the blood effectively, causing fluid to back up and create congestion in the tissues of the lungs, liver, GI tract, arms, and legs
Congestive heart failure
Connect bone to bone
Ligaments
Permanent deformity of a joint caused by atrophy of surrounding muscles
Contracture
What happens to responses and reflexes as we age
They get slower
A progressive, neurological disease which affects the transmission of nerve impulses to and from the brain resulting in functional impairment
Multiple sclerosis (MS)
Tiny blood vessels where the exchange of oxygen and nutrients takes place
Capillaries
Narrowing of the arteries other than those that supply the heart or brain. The main risk factor for this condition is cigarette smoking.
Peripheral vascular disease (PVD)
Connect muscle to bone
Tendons
Disease caused by the wearing away of cartilage, causing the ends of two bones to deteriorate and rub together
Osteoarthritis
Decreased blood flow to certain areas of the brain can cause this
Short-term memory loss
Developmental disability that refers to a group of disorders characterized by spasticity on one side of the body, affecting posture, balance, and movement
Cerebral palsy
As we age, the heart muscle has to work harder resulting in high _______________ _______________
Blood pressure
This is a disease in which the arteries that supply blood to the heart muscle become hardened and narrow due to a buildup of cholesterol and other material, called plaque, on their inner walls
Coronary artery disease (CAD)
As we age, posture involves slightly bent hips, bowed knees, stooped shoulders and a flexed neck which leads to a reduction in this
Height
Autoimmune disorder that causes inflammation in the lining of the joints
Rheumatoid arthritis
