GALL BLADDER: The reservoir for bile located between the right and quadrate lobe on the posteroinferior surface of the liver. image

GASTRODUODENAL ARTERY: The artery which originates from the common hepatic artery and branches into the supraduodenal and posterior superior pancreaticoduodenal arteries. image

GASTROESOPHAGEAL JUNCTION: The point where the stratified squamous epithilium of the esophagus meets the simple columnar epithilium of the cardia of the stomach. The GE junction may be above the diaphragm when there is a hiatal hernia. In turn, hiatal hernia may be associated with GERD (Gastroesophageal Reflux Disease). image

GLENOID FOSSA: The a shallow "cup" on the lateral edge of the scapula that is the point of articulation between with the head of the humerus. image

GLOBE: The eyeball. image

GLOSSOEPIGLOTTIC FOLD: The folds of mucous memrane located between the tongue and epiglottis. image

GLOTTIS: A synonym for the vocal cords. image

GLUTEUS MAXIMUS: Muscle originating form the lateral surface of the ilium, dorsal surface of the sacrum and coccyx, and the sacrotuberus ligament, and inserting into the iliotibial tract of the facia lata, and the gluteal tuberosity of femur. It is responsible for the extension. abduction, and lateral rotation of the thigh. image

GLUTEUS MEDIUS: Muscle originating between the anterior and posterior gluteal lines at the lateral surface of the ilium, and inserting at the greater trochanter of the femur. It is responsible for abduction of the thigh. image

GLUTEUS MINIMUS: Muscle originating between the anterior and posterior gluteal lines at the lateral surface of the ilium, and inserting at the greater trochanter of the femur. It is responsible for the abduction and medial rotation of the thigh. image

GRACILIS: Muscle that originates at the inferior ramus of the pubis, and inserts into the medial surface of the tibial shaft. It is responsible for adduction of the thigh and flexion of the knee. image

GREATER CURVATURE (STOMACH): The lateral and inferior border of the stomach. image

GREATER TROCHANTER (FEMUR): Process on the lateral surface of the proximal femur, the point of attachment for the gluteus medius and minimus. image image

GREATER TUBEROSITY (HUMERUS): Prominence on the lateral surface of the proximal humerus. Point of attachment for the infraspinatus, supraspinatus, and teres minor muscles. image

GREATER WING OF SPHENOID: Winged-shaped process of the sphenoid bone that helps form the floor and lateral walls of the middle cranial fossa and the lateral wall of the orbit. image
