Chapter 9, Problem 3CCS
Let’s continue our tale of Mrs. DeStephano’s medical problems, this time looking at the notes made detailing Mrs. DeStephano, a 45-year-old woman badly injured in a traffic accident, has been admitted to the hospital. Several of the notes in her chart detail observations of her skeletal musculature.
Severe lacerations of the muscles of the right leg and knee
Damage to the blood vessels serving the right leg and knee
Transection of the sciatic nerve (the large nerve serving most of the lower limb), just above the right knee
Her physician orders daily passive range-of-motion (ROM) exercise and electrical stimulation for her right leg and a diet high in protein, carbohydrates, and vitamin C.
What complications in muscle structure and function result from transection of the sciatic nerve? Why are passive ROM and electrical stimulation of her right leg muscles ordered?

Apart from food, plants need other nutrients like water and minerals.
Nitrogen, a mineral, is an important part of all living cells. All organisms need nitrogen in order to grow and repair.
Although nitrogen exists in its elemental form in the atmosphere, it cannot be directly used by plants.
7 Where else can plants obtain their nitrogen from?
Plants make their own nitrogen.
B Plants get it from animals.
Plants get it from the soil.
D
Plants have special structures to break down
atmospheric nitrogen.
