Explanation: The supraspinatus muscle is located in the supraspinous fossa of the scapula and is one of the four rotator cuff muscles of the shoulder joint. It is responsible for initiating abduction of the arm and stabilizing the shoulder joint. Injury or strain to the supraspinatus muscle is a common cause of shoulder pain and limited range of motion, especially during abduction of the arm. Tenderness over the anterior shoulder can be a result of referred pain from the supraspinatus muscle. Infraspinatus, subscapularis, and teres major are also rotator cuff muscles, but they are less likely to be involved in this presentation.

45 yr ♂️ presents with pain & limited range of motion in his left shoulder.Upon examination,there is tenderness over the anterior shoulder,the patient reports pain when attempting to move the shoulder.Of the following muscles is most likely affected?

Explanation: The radial nerve is a nerve that arises from the posterior cord of the brachial plexus and runs down the arm, along the radial bone. It supplies the extensor muscles of the arm and forearm, including the triceps brachii muscle, and the muscles that extend the wrist and fingers. The radial nerve also provides sensory innervation to the dorsal aspect of the hand. A lesion or injury to the radial nerve can result in wrist drop, which is the inability to extend the wrist and fingers. This can be caused by a number of factors, including trauma, compression, or neuropathy. The other nerves listed (median, ulnar, and axillary nerves) do not supply the extensor muscles of the wrist and fingers and are less likely to be involved in this presentation.

32 ♂️ presents with wrist drop, decreased sensation over dorsal aspect of Right hand, unable to extend wrist/fingers.Which of the following nerves is most likely to be affected?

Explanation: Sibson's fascia is a thin layer of fascia that extends from the transverse processes of the cervical vertebrae to the first rib and the manubrium of the sternum. It separates the superior mediastinum from the superior thoracic aperture, and it is continuous with the prevertebral fascia and the endothoracic fascia. The fascia covering the posterior surface of the sternoclavicular joint is called the suprasternal fascia. The fascia extending from the cricoid cartilage to the inferior border of the first rib is called the pretracheal fascia. Sibson's fascia does not separate the pleural cavity from the mediastinum.
18 238
Which of the following statements is true about the anatomy of Sibson's fascia?
18 238
Explanation: The patient's symptoms suggest inflammation in the third intercostal space, which is located between the third and fourth ribs. This space contains the intercostal nerve, artery, and vein, which make up the neurovascular bundle. Tenderness and swelling in this area may indicate irritation or injury to the nerves or blood vessels. The external intercostal muscles (A), internal intercostal muscles (B), and innermost intercostal muscles (C) are all muscle layers located between the ribs, but they are not directly related to the patient's chest pain and tenderness.

A 55 yr ♂️ male presents with sharp chest pain & shortness of breath.Physical examination reveals tenderness and swelling in the third intercostal space on the left side of the chest.Which of the following anatomical structures is most likely affected?

Explanation: The great saphenous vein is a large, superficial vein that runs along the medial aspect of the leg from the ankle to the groin. This vein is often affected in conditions such as varicose veins, chronic venous insufficiency, and deep vein thrombosis. In this scenario, the patient's prominent varicose veins, chronic lower extremity swelling, and pain may suggest chronic venous insufficiency, which is a common complication of great saphenous vein incompetence.

A 58-year-old male patient presents with chronic lower extremity swelling and pain. On examination, you note prominent varicose veins in the patient's legs. What is the name of the vein that is most commonly affected in this condition?

Explanation: The digastric triangle is an anatomic space in the anterior triangle of the neck that is bordered by the anterior belly and posterior belly of the digastric muscle, and the lower border of the mandible. This triangle encompasses important structures such as the submental lymph nodes, the submental artery, and the mylohyoid muscle. In this scenario, the small non-pulsatile mass located beneath the floor of the mouth, near the submental area, is most likely a submental lymph node, which may suggest an underlying infection or inflammation. It is important to note that appropriate imaging studies and laboratory tests may be necessary to help determine the cause of the patient's symptoms and to determine the appropriate management plan.

A 35-year-old female patient presents with a sharp pain in the submental region. On examination, you note a small non-pulsatile mass located beneath the floor of the mouth. What is the name of the triangle that encompasses this region?
18 238
Explanation: The carotid triangle is an anatomical space in the anterior triangle of the neck that contains important structures such as the common carotid artery, internal jugular vein, and vagus nerve. In this scenario, the pulsatile mass observed in the patient's neck is most likely the common carotid artery, which may suggest a potential pathology such as a carotid artery aneurysm or dissection.

Incorrect answer explanations: A) The median nerve arises from the lateral and medial cords of the brachial plexus and innervates the flexor muscles of the wrist and fingers. It would not be affected by a mass in the axillary region. B) The radial nerve arises from the posterior cord of the brachial plexus and innervates the extensor muscles of the wrist and fingers, as well as the skin over the posterior aspect of the forearm and hand. It would not be affected by a mass in the axillary region. C) The ulnar nerve arises from the medial cord of the brachial plexus and innervates the flexor muscles of the wrist and hand, as well as the skin over the medial aspect of the hand. It would not be affected by a mass in the axillary region. E) The musculocutaneous nerve arises from the lateral cord of the brachial plexus and innervates the biceps brachii, brachialis, and coracobrachialis muscles, as well as the skin over the lateral aspect of the forearm. It would not be affected by a mass in the axillary region.

Correct answer: D) Axillary nerve. The axillary nerve arises from the posterior cord of the brachial plexus and innervates the deltoid and teres minor muscles, as well as the skin over the lower part of the deltoid muscle. A mass in the axillary region that is compressing the brachial plexus would most likely affect the axillary nerve, leading to weakness in the deltoid and teres minor muscles, as well as numbness over the skin supplied by that nerve.

A 35-year-old man with left arm weakness, wrist extension inability, and sensory loss in lateral forearm/hand has a mass in axillary region compressing the brachial plexus. Which nerve is most likely affected?
18 238
The correct answer is D) Levator ani, which is not located in the perineum but rather in the pelvic floor. The ischiocavernosus, bulbospongiosus, and transverse perineal muscles are all located in the perineum and could potentially be affected by an infection in the prostate gland.

Which muscle is unaffected by the infection in the prostate gland of a 45-year-old male who presents with difficulty urinating and perineal pain, as suspected by the physician after physical examination?
