Anatomy Hollow, muscular, very distensible, pear-shaped organ under liver; receives bile through common hepatic, cystic ducts; concentrates (strengthens) and reserves; releases into cystic duct, on to common bile duct, ampulla of Vater, duodenum through papilla; c. 3″ long, 4″ diameter full; fundus, body, neck (sometimes with saccular Hartman’s pouch), tapering to duct; inferior covered by

Anatomy Origin: Frontalis has no bony origin. Its fibres are continuous with those of the muscles procerus and corrgator supercilii. Insertion: Fibres join the galea aponeurotica (epicranial aponeurosis) below the coronal suture. Key Relations: Many consider frontalis and occipitalis as one muscle (called occipitofrontalis) with an aponeurotic tendon between two bellies- a frontal belly and

Anatomy Small notch at medial margin on top of each eye socket, through which supra-orbital vessels and nerve pass through. Can be a foramen or a notch. Vignette Swimmer’s headache may be caused by tight goggles pressing on supraorbital nerve at (or near) notch. Interested in taking our award-winning Pocket Anatomy app for a test

Anatomy Section of frontal bone which forms part of eye sockets/orbits. Frontal bone curves in at bottom, as thin triangular orbital plates. Left and right plate are separated by a gap – the ethmoid notch. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Pyramidal lower extremity of fibula, runs down lateral to and articulates (medially/in) with the talus, behind and in front of which joint there are posterior and anterior talofibular ligaments, and below which, from the point/summit is the calcaneofibular ligament (down and slightly back). The visible outer knob of the ankle. Clinical Ankle injuries most

Anatomy Origin: Superficial part: Flexor retinaculum and tubercle of the trapezium. Deep part: Trapezoid and capitates. Insertion: Base of the proximal phalanx of thumb. Key Relations: Is one of the muscles of the thenar eminence of the hand. Functions Flexion of the thumb at the metacarpophalangeal joint. Supply Nerve Supply: Superficial part: Recurrent branch of

Anatomy Origin: Lower two-thirds of the posterior surface of the fibula, the posterior intermuscular septum and the posterior surface of the distal part of the interosseous membrane. Insertion: Plantar surface of the base of the distal phalanx of the hallux (big toe). Key relations: -One of the four muscles of the deep posterior compartment of

Anatomy Origin: Humeroulnar head: Medial epicondyle of humerus via the common flexor tendon, ulnar collateral ligament and coronoid process of ulna. Radial head: Superior half of anterior aspect of radius at anterior oblique line. Insertion: Four tendons of insertion attach to palmar surfaces of bodies of middle phalanges of the four fingers. Key Relations: -The

Anatomy Origin: Plantar surface of the base of the 5th metatarsal and sheath of adjacent fibularis longus tendon. Insertion: Base of the 5th proximal phalanx. Key Relations: Runs along the lateral aspect of the foot. See plantar view of flexor digiti minimi brevis of foot.. Functions Flexes the 5th toe at metatarsophalangeal joint. Supply Nerve

Anatomy Origin: Upper three quarters of medial and anterior aspects of ulna and from anterior aspect of interosseous membrane. Insertion: Four tendons attaching to palmar aspects of bases of the distal phalanges of each of the four fingers. Key Relations: -The lumbrical muscles arise in the palm from the tendons of flexor digitorum profundus. -The
