period of life starting from the decline in ovarian activity until after the end of ovarian function
According to the definition, the period includes peri-menopause, menopause and post-menopause
recommended calcium and vitamin d intakes
calcium ranges from 1000-1200 through ages 50-70

slide 17 - chart that shows which risk factors are in place for Osteoporosis, Osteoarthritis, and Rheumatoid Arthritis
study - see if it is testable
Psychological Implications of these bone and joint conditions
gender diffs
gender diff - Compensation for Loss
women - cosmetics, hair dye, surgery
men - increasing use by men ?
slide 18 - Appearance vs actual Loss in Strength and Endurance
exercise and resistance training

4 Psychological changes of Eye loss/changes
Loss of activities - reading, tv, driving

Corrective actions - glasses, surgery (cataracts), corrective environmental changes
Hearing loss
damage to __ _______, _______ effects
5 social effects of hearing loss
due to loud environments, cumulative effects
Independence loss, Isolation, Irritation, Paranoia, Depression
3 mechanisms for hearing loss
Analog hearing aid - mold on outer ear, sends sound through tube to microphone, microphone sends sound to an Amplifier which enhances sound and sends it to the receiver, receiver sends amplified sound to ear
Digital hearing aid - similar to analog, but use directional microphone to control flow of sound. tech allows volume control. microchips allow programming for diff situation. tech allows multiple channels to deliver sound w varying amplification
Cochlear Implant - implants do not make sound louder, rather itis a series of components. microphone picks up sound, digitized by microchips turned into coded signals, broadcasted by FM radio signals to electrodes that are inserted in ear. electrodes stimulate auditory nerve fibers directly
24 - 2 aspects of Somatosensory System

young heart at rest vs during hard exercise
at rest - at start of heart beat at rest, at end of heart beat at rest
during hard exercise, size at start of heartbeat is the same as the rest, size at end of heart beat is smaller than the rest
old heart at rest vs during hard exercise
at rest - at start of heart beat at rest, end of heart beat at rest
during hard exercise - size at start of heartbeat is larger than the rest, size at end of heart beat is same as at rest
visual - normal artery vs narrowing artery
normal artery is clear for blood to flow through
narrower artery has a build of plaque that narrows the flow - leads to abnormal blood flow
