These are the three specific types of semilunar cusps found in the Aortic Valve.
What are the posterior, right, and left cusps?
This nerve, which supplies the serratus anterior, is unique because it travels along the superficial surface of the muscle rather than deep to it.
What is the long thoracic nerve?
This specific cervical disc is the only one that characteristically refers pain superiorly into the head.
What is the C2 disc?
This "joint" is a muscular articulation between the concave anterior scapula and the convex posterior rib cage.
What is the scapulothoracic joint?
While multiple muscles flex the fingers, this one is the only one of them that can flex the distal interphalangeal (DIP) joints.
What is the flexor digitorum profundus (FDP)?
This small, smooth-walled area of the left ventricle serves as the outflow tract leading to the aortic orifice.
What is the aortic vestibule?
This part of the brachial plexus passes through the gap between the anterior and middle scalene muscles.
What are the roots (ventral rami)?
These joints, unique to the cervical spine, create a "bivalve" or "bipartite" disc by age 25.
What are the uncovertebral joints (Joints of Luschka)?
This ligament, found in the elbow, encircles the head of the radius to allow for pivoting.
What is the annular ligament?
This carpal bone is the most commonly fractured and is located in the floor of the anatomical snuffbox.
What is the scaphoid?
This crescent-shaped depression in the interatrial septum is a remnant of the foramen ovale.
What is the fossa ovalis?
These are the three specific branches that arise from the third part of the axillary artery.
What are the subscapular, anterior circumflex humeral, and posterior circumflex humeral arteries?
This muscle is an essential landmark that divides the anterior and posterior triangles of the neck.
What is the sternocleidomastoid (SCM)?
This is the ratio of glenohumeral to scapulothoracic motion during full shoulder abduction.
What is 2:1 (Scapulohumeral Rhythm)?
This nerve pierces the supinator muscle through the Arcade of Frohse.
What is the deep branch of the radial nerve (PIN)?
This specific arterial branch typically arises from the left coronary artery and passes in the coronary sulcus to reach the posterior surface of the heart.
What is the circumflex branch?
This terminal branch of the medial cord provides sensory innervation to the medial side of the forearm.
What is the medial antebrachial cutaneous nerve?
These are the three parts of the longus colli muscle.
What are the superior oblique, inferior oblique, and vertical parts?
This structure is the primary stabilizer of the distal radioulnar joint and is frequently injured in wrist traumas.
What is the TFCC (Triangular Fibrocartilage Complex)?
These four muscles make up the thenar compartment of the hand.
What are the abductor pollicis brevis, flexor pollicis brevis, opponens pollicis, and adductor pollicis?
This unusual vascular relationship occurs because blood flows in the same direction within this paired artery and vein on the left side of the heart.
What are the circumflex branch and the great cardiac vein?
This cord of the brachial plexus is formed by the union of the anterior divisions of the upper and middle trunks.
What is the lateral cord?
This specific muscle of the neck is innervated by the facial nerve (CN VII) and helps depress the mandible or draw the corners of the mouth inferiorly.
What is the platysma?
During wrist flexion, this specific percentage of the motion occurs at the midcarpal joint.
What is 60%?
In the deep layer of the hand, the adductor pollicis is unique because of this nerve that innervates it.
What is the deep branch of the ulnar nerve?
