- B. Right atrium and ventricle
- C. Interventricular septum
- D. I.V.C. and right ventricle
Explanation: The diaphragmatic or inferior surface of the heart is formed mainly by the left ventricle, with a smaller contribution from the right…
Correct answer: Right and left ventricle- A. Right bronchus is more vertical and broader than the left
- B. Right bronchus is more vertical and has a narrow caliber than the left
- C. Left bronchus is more vertical and broader than right
- D. Left bronchus is more vertical and narrower than right
Explanation: The right main bronchus is shorter, wider and more vertical than the left, which is why aspirated foreign bodies more commonly enter it.
Correct answer: Right bronchus is more vertical and broader than the left- A. Sternal angle
- B. 5th inter costal space
- C. 3rd thoracic vertebrae
- D. thoracic vertebrae
Explanation: The trachea bifurcates at the carina near the sternal angle, corresponding approximately to the T4-T5 intervertebral level.
Correct answer: Sternal angle- A. Bronchial artery
- B. Tracheal artery
- C. Inferior thyroid artery
- D. Superior thyroid artery
Explanation: The cervical trachea receives blood mainly from the inferior thyroid arteries, while the thoracic part is supplied by bronchial arteries.
Correct answer: Inferior thyroid artery- A. Lower end of cricoid
- B. C5 vertebra
- C. 10 cm from incisor teeth
- D. C7
Explanation: The oesophagus begins at the lower border of the cricoid cartilage, approximately opposite the C6 vertebra.
Correct answer: Lower end of cricoid- A. 60 cm proximal to ileocecal junction
- B. 1stpart of duodenum
- C. Esophago gastric junction
- D. Pharyngo esophageal junction
Explanation: The pharyngoesophageal junction is the narrowest point of the gastrointestinal tract, owing mainly to the cricopharyngeus muscle.
Correct answer: Pharyngo esophageal junction- A. Fibrous joint
- B. Synovial joint
- C. Fmosis
- D. Synarthrosis
Explanation: The first costochondral joint is a primary cartilaginous joint, or synchondrosis, and is functionally immovable, making it a synarthrosis.
Correct answer: Synarthrosis- A. Brachio cephalic trunk
- B. Ascending aorta
- C. Arch of aorta
- D. Left common carotid
Explanation: The left subclavian artery arises directly from the arch of the aorta, along with the brachiocephalic trunk and left common carotid…
Correct answer: Arch of aorta- A. Radial artery
- B. Brachial artery
- C. External carotid artery
- D. Femoral artery
Explanation: The brachial artery lies close to the median nerve in the arm and cubital fossa, so brachial arterial puncture can injure it.
Correct answer: Brachial artery- A. Principal artery of upper limb
- B. Right subclavian artery is a branch of brachioceplialic artery
- C. Left subclavian artery is a branch of arch of aorta
- D. Internal thoracic, verterbraland thyro cervical trunk are branches of subclavian artery
- E. All of the above
Explanation: The subclavian artery is the principal artery of the upper limb: the right arises from the brachiocephalic trunk and the left from the…
Correct answer: All of the above- A. Radial nerve
- B. Ulnar nerve
- C. Median nerve
- D. Vidian nerve
Explanation: An ulnar nerve lesion paralyzes the interossei and medial two lumbricals, producing hyperextension at the MCP joints and flexion at the IP…
Correct answer: Ulnar nerve- A. Trapezius
- B. Rhomboid major
- C. Rhomboid minor
- D. Levator scapulae
Explanation: Trapezius and both rhomboids retract the scapula by drawing it medially toward the vertebral column.
Correct answer: Levator scapulae
