Concept explainers
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?

Functionally, joints may be called synarthroses, amphiarthroses, or diarthroses. Joints with a very tight union that allows no movement are synarthroses (syn union + arthro joint). They include sutures between the cranial bones and the joints between the teeth and their sockets. Joints allowing a limited movement are amphiarthroses (amphi = two sides), and include the intervertebral discs and the pubic symphysis. Joints that allow a large range of movement are known as diarthroses (di= apart). As you may suspect, they include the shoulder, elbow, knee, and most of the remaining joints of the body. Identifying Joints by Function You will review the functional classification of joints in this observational exercise. 1. Identify the functional category of the joints as synarthroses, amphiarthroses, or diarthroses by completing the labels in…arrow_forward
