Theories of Aging Flashcards
an unstable molecules produced by body during respiration and metabolism or exposure to radiation and pollution
free radical theory
can cause physiological problems such arthritis, circulatory diseases, diabetes and atherosclerosis
free radical theory
a cell from DNA and connective tissue interact with free radicals to cause bonds that decrease ability of tissue to replace itself
crosslink theory
a cell from DNA and connective tissue interact with free radicals to cause bonds that decrease ability of tissue to replace itself
crosslink theory
in this theory, it can result skin changes such as dryness, wrinkles and loss of elasticity
crosslink theory
a combination of three theories which is free radical, somatic and crosslink theory that damage body organs such as muscle, heart, nerves and brain
clinker theory
in this theory, the body is similar to machine which loses function when its parts wear out
wear-and-tear theory
in this theory, the more you experience physiologic failure, the higher chance your lifespan is low
reliability theory or aging and longevity
in this theory, the more you experience physiologic failure, the higher chance your lifespan is low
reliability theory or aging and longevity
in this theory, it focuses on the complicated chemical interactions set off by the hypothalamus of the brain.
neuroendocrine theory
in this theory, it focuses on the complicated chemical interactions set off by the hypothalamus of the brain.
neuroendocrine theory
growth hormones
muscle masa atrophy
sex hormones
no ovulation, menouposal
the more you age, the more the T cells or B cells decrease its function
immunologic theory
best diet for older adults
low calorie intake with high dents nutrients
older adults are separated, excluded or disengaged from society because they not perceived to benefit to society
disengagement theory
physical and mental activities and interactions that promotes self esteem improve satisfaction in life
activity theory
in this theory, late adulthood is the time where they review their lives and determine whether they have been negative or positive overall
erickson’s theory
this theory where delineates specific tasks for late life
havighurst’s theory
this theory where delineates specific tasks for late life
havighurst’s theory
in this theory, aging is not just about a decline on physical changes but a normal process of adaptation in normal development
newman’s theory
this theory proposes that development continues throughout life by questioning, searching and setting goals with individuals personality
jung’s theory
older adults begin to question whether decision and choices were right choices for them
midlife crisis
the outermost layer of skin that
provides protection, keeps out chemicals and microorganisms and
regulates body temperature and eliminate waste
products.
epidermis
contains collagen and elastin fibers, which give strength and elasticity to the tissues.
dermis
consists of areolar connective tissue, which connects the skin to the muscles, and adipose tissue, which provides a cushion over tissue and bone.
subcutaneous tissue
red, purple, or brown areas commonly seen on the legs and arms.
senile purpura
This is a significant problem for immobilized people such as those who are bedridden or confined to wheelchairs
pressure ulcers
appears as redness, dilated superficial blood vessels, and small “pimples” on the nose and center of the face
rosacea
appear as rashes or inflammation that is either localized to certain areas of the body or generalized
contact or allergic dermatitis
is an unsightly skin condition characterized by yellow, waxy crusts that can be either dry or moist
seborrheic dermatitis
provide a rigid structure that gives the body its shape.
skeletal bones
produces red blood cells (RBCs), platelets, and WBCs.
red bone marrows
provide a power source to move the bones.
muscle
is necessary for bone strength, muscle contraction, myocardial contraction, blood clotting, and neuronal activity.
calcium
needed for the absorption of calcium and phosphate through the small intestine.
vitamin d
helps slower movement of calcium to bone from blood, lowering blood calcium levels
calcitonin
helps faster movement of calcium to bone from blood increasing the blood calcium level
parathyroid gland
helps protein synthesize and energy production
insulin and thyroxine
helps retain calcium in the bone matrix
estrogen and testosterone
supports the head and allows for flexible movement of the back
spinal column
this is where the bones meet
joints
allow free movement of joint
cartilage
provides lubrication to enhance joint mobility
bursa
connect muscle to bone
tendons
connect bones to other bones
ligaments
is found in the walls of hollow organs such as the blood vessels, stomach, intestines, and urinary bladder
smooth muscle
Controlled and coordinated movement of bones and muscles allows us to perform the variety of movements required for activities of daily living.
muscles
bone renewing cells
osteoblast
the intervertebral disk shrinks/ the depletion pf fluid between intervertebral disk
kyphosis
