Which muscle is the primary hip flexor and originates from the lumbar vertebrae?
Answer: Iliopsoas
The iliopsoas, composed of the iliacus and psoas major, is the primary hip flexor. The psoas major originates from the transverse processes and bodies of L1-L5 vertebrae.
The close-packed position of the glenohumeral joint is:
Answer: Full external rotation with 90 degrees abduction
The close-packed position of the glenohumeral joint is full external rotation combined with 90 degrees abduction, where joint surfaces are maximally congruent and ligaments are taut.
The Q-angle is measured between the line from the ASIS to the patella center and which other line?
Answer: Patella center to the tibial tuberosity
The Q-angle is formed between the line from the ASIS to the patella center and the line from the patella center to the tibial tuberosity. Normal values are approximately 10-15 degrees for men and 15-20 degrees for women.
Which nerve innervates the diaphragm?
Answer: Phrenic nerve (C3-C5)
The phrenic nerve (C3, C4, C5) provides motor innervation to the diaphragm. The mnemonic 'C3, 4, 5 keeps the diaphragm alive' is widely used.
The muscle responsible for scapular upward rotation during arm elevation above 90 degrees is:
Answer: Serratus anterior and lower trapezius force couple
Scapular upward rotation above 90 degrees requires the serratus anterior and lower trapezius force couple, along with the upper trapezius, to efficiently rotate the glenoid upward.
Which of the following joints is classified as a condyloid (ellipsoid) joint?
Answer: Radiocarpal (wrist) joint
The radiocarpal (wrist) joint is a condyloid joint, allowing flexion/extension and radial/ulnar deviation but no axial rotation.
