This triangle of the neck is bordered by the SCM, trapezius, and clavicle
Posterior cervical triangle
This structure protects vital organs and consists of the ribs, thoracic vertebrae, and the sternum
Thoracic cage
This bony process of the scapula forms the highest point of the shoulder and articulates with the clavicle
Acromion process
This bony point, felt in the back of the elbow, is part of the ulna and serves as the insertion point for the triceps brachii
Olecranon
These 8 small bones are arranged in two rows and form the skeleton of the wrist
Carpal bones
The sternohyoid, omohyoid, sternothyroid, and thyrohyoid muscles are all innervated by this nerve loop formed by C1-C3
Ansa cervicalis
A typical intercostal space contains these three main structures arranged from superior to inferior
Intercostal vein, artery, and nerve
This muscle originates on the spine of the scapula and inserts on the deltoid tuberosity. It is innervated by the axillary nerve and abducts the arm.
Deltoid
The proximal radioulnar joint is classified as this type of synovial joint
Pivot joint
This structure, formed by the flexor retinaculum and carpal bones, contains the median nerve and tendons of FDS, FDP, and FPL
carpal tunnel
This cranial nerve passes through the foramen ovale and supplies many muscles, but specifically the muscles of mastication
CN V Mandibular branch (V3)
This type of pleura lines the inside of the thoracic wall and is sensitive to pain, pressure, and temperature
parietal pleura
This large nerve network supplies the upper limb and is formed by the anterior rami of spinal nerves C5-T1
brachial plexus
This muscle originates from the supraglenoid tubercle and radial tuberosity and is innervated by the musculocutaneous nerve
biceps brachii
These ligaments prevent excessive side-to-side movement at MCP and IP joints and are commonly sprained in sports injuries
Collateral ligaments
This muscle, innervated by CN IV, depresses and medially rotates the eye
Superior oblique
This venous system drains blood from the gastrointestinal tract to the liver and contrasts with the system that drains directly into the inferior vena cava
portal venous system
This space is a passageway from the neck to the axilla and transmits the brachial plexus, axillary artery/vein. It is bordered by the clavicle, 1st rib, and sueprior scapula
Cervicoaxillary canal
These nerves innervate the flexor digitorum profundus
Median and ulnar nerves
This muscle, innervated by the median nerve, inserts on the lateral side of the base of the proximal phalanx of the thumb to assist in a unique thumb movement
Opponens pollicis
This cranial nerve provides motor innervation to most muscles of the pharynx and larynx and is responsible for the efferent limb of the cough reflex
Vagus nerve ( CN X)
this nerve arises from L1 of the lumbar plexus and innervates the internal oblique and transversus abdominis muscles
iliohypogastric nerve
An injury to the posterior cord of the brachial plexus may result in wrist drop due to damage to this nerve
radial nerve
This deep forearm muscle is responsible for pronating the forearm and is innervated by the median nerve
Pronator quadratus
A patient presents with claw hand deformity and sensory loss over the medial 1.5 digits. Damage is most likely to this nerve
Ulnar nerve
