Clinical Anatomy — Flashcards

Answer: L3

Flashcard 62: Loss of muscle action in an _____ nerve injury includes loss of:1. wrist flexion2. flexion of medial fingers (4th and 5th digits)3. abduction AND adduction of fingers (interossei)4. medial 2 lumbricals (4th and 5th digits)

Answer: ulnar

Flashcard 63: _____ (condition) is due to compression of the lower trunk (roots C8-T1) and subclavian vessels

Answer: Thoracic outlet syndrome

Flashcard 64: Radial Head Dislocation impinges the _____ nerve, causing weakness of most of the posterior forearm extensors

Answer: deep radial

Flashcard 65: The optimal site for obtaining vascular access in the lower extremity during cardiac catheterization is the _____ artery below the inguinal ligament

Answer: femoral

Flashcard 66: A cricothyrotomy establishes an airway between the cricoid and thyroid cartilages and requires an incision through (superficial to deep):1) skin2) _____ fascia3) investing and pretracheal fascial layers of the deep cervical fascia 4) cricothyroid membrane

Answer: superficial cervical

Flashcard 67: _____ fractures of the temporal bone are more common than transverse

Answer: Longitudinal

Flashcard 68: Seminiferous tubules, _____ chamber of the eye, the cornea and the brain are immunologically privileged sites

Answer: anterior

Flashcard 69: Intramuscular injections in the gluteal region should be given in the _____ quadrant or the ventrogluteal site (von Hochstetter triangle) to avoid injury to the sciatic nerve.

Answer: superolateral

Extra: The gluteal region is traditionally divided into four quadrants. The **superolateral quadrant** is the safe zone for dorsogluteal injections because it avoids the sciatic nerve (located medially and inferiorly) and the superior gluteal nerve (located medially). The **ventrogluteal site**, identified using the **von Hochstetter triangle**, is another safe alternative that is far from major neurovascular structures.

Flashcard 70: Which areas of the spinal cord are spared in a complete occlusion of the anterior spinal artery? _____ and Lissauer's tract

Answer: Dorsal columns
