Clinically Oriented Anatomy 6th edition Introduction to Clinically Oriented Anatomy Which of the following is true pertaining to the tension (Langer) lines of the skin? Surgical incisions should be made parallel to these lines to minimize scaring. Surgical incisions should avoid cutting through these lines because they contain neurovascular bundles. Surgical incisions should avoid cutting through these lines because they indicate the position of the underlying skin ligaments (retinacula cutis). They become stretch marks (striae gravidarum) in obese individuals. They separate fascial compartments. Which of the following is true pertaining to the tension (Langer) lines of the skin?

Your immediate reaction is to: dismiss the finding because there are often small sutural (wormian) bones within skull sutures that have no clinical significance. request a head CT because these bones often develop after head injuries and can be associated with seizures. assume that your patient had a vitamin D deficiency during childhood. assume that your patient had a fontanelle that remained open beyond the normal period. assume that your patient has a minor case of hydrocephalus.

Which of the following is incorrect pertaining to joints? They receive blood from vessels surrounding the joint. Most articular nerves are branches of the nerves to the muscles that cross the joint. Loss of nerve supply results in avascular necrosis of the joint. Some joints do not permit any movement. Joint nerves transmit proprioceptive information.

Which of the following is incorrect pertaining to plain radiographs? In a PA projection the x-rays traverse the patient from posterior to anterior. To minimize distortion the region of the body being examined should be as close as possible to the x-ray film or detector.

Enhancement of the visibility of certain structures on radiographs is facilitated by having the patient ingest a barium-containing compound. Standard chest radiographs should be viewed as if you were facing the patient. Which of the following is incorrect pertaining to plain radiographs?

PowerPoint Quiz Essential Clinical Anatomy 4th edition Introduction to Clinically Oriented Anatomy Which of the following is true pertaining to the tension (Langer) lines of the skin? Surgical incisions should be made parallel to these lines to minimize scaring. Surgical incisions should avoid cutting through these lines because they contain neurovascular bundles. Surgical incisions should avoid cutting through these lines because they indicate the position of the underlying skin ligaments (retinacula cutis). They become stretch marks (striae gravidarum) in obese individuals. They separate fascial compartments. Which of the following is true pertaining to the tension (Langer) lines of the skin?

Your immediate reaction is to: dismiss the finding because there are often small sutural (wormian) bones within skull sutures that have no clinical significance. request a head CT because these bones often develop after head injuries and can be associated with seizures. assume that your patient had a vitamin D deficiency during childhood. assume that your patient had a fontanelle that remained open beyond the normal period. assume that your patient has a minor case of hydrocephalus.

Which of the following is incorrect pertaining to joints? They receive blood from vessels surrounding the joint. Most articular nerves are branches of the nerves to the muscles that cross the joint.

The fracture should be "reduced" to heal properly. A collar of bone (callus) forms to hold the bones together while healing. Greenstick fractures are most common in the elderly. Osteoporotic bones break more easily than normal bones. Tearing of the periosteum accounts for the acute pain associated with fracture.
