gastrocnemius muscle
Muscle formed of two heads (lateral and medial) connecting the femur to the calcaneus; it allows the plantar flexion of the foot and knee.

gastrosplenic ligament
Peritoneal ligament connecting the spleen and greater curvature of the stomach.

genicular veins

genioglossus muscle
Muscle connecting the mandible to the hyoid bone and tongue; it mainly allows the tongue to move forward or backward.

geniohyoid muscle
Muscle connecting the mandible and hyoid bone; it especially allows the lower jaw to be lowered.

glenoid cavity
Hollow articular surface of the scapula, in which the head of the humerus pivots.

glossopharyngeal nerve
Mixed cranial nerve associated with swallowing, gag reflex, taste and sensations from the pharynx and posterior part of the tongue.

gracilis muscle
Muscle connecting the pubis to the tibia; it allows the thigh to move toward the axis of the body (adduction) and the leg to flex and rotate inward.

great adductor muscle
Muscle connecting the pubis and ischial tuberosity to the femur; it allows the thigh to move toward the axis of the body (adduction), rotate outward, flex and extend.

great auricular nerve
Nerve arising from the cervical plexus, innervating the skin of the pinna and part of the cheek.

great cardiac vein
Vein draining blood from the left side of the heart.

great saphenous vein
Vein collecting the blood of the medial side of the leg and thigh and receiving certain veins of the foot. It is the longest vein in the body.

greater curvature of stomach
Left border of the stomach on which the great omentum inserts.

greater gluteal muscle
Thick muscle forming the thigh, allowing the trunk to be supported in a vertical position.

greater occipital nerve
Twig of the second cervical nerve, especially innervating the semispinosus muscle of the head and back part of the scalp.

greater palatine foramen
Canal of the hard palate, allowing the passage of vessels and nerves.

greater pectoral muscle
Muscle of the thorax formed of two heads, connecting the sternum and clavicle to the humerus; it allows the adduction and rotation of the arm.

greater psoas muscle
Muscle connecting the posterior abdominal wall to the lesser trochanter; it allows flexion of the thigh or forward bending of the trunk.

greater splanchnic nerve
Nerve arising from several nodes of the thoracic sympathetic chain and ending at the celiac plexus; it innervates the abdominal viscera.

greater trochanter
Protrusion of the external part of the upper extremity of the femur, where several muscles of the thigh and buttock insert.

greater tubercle
Protrusion of the neck of the humerus, where various shoulder muscles insert.

greater zygomatic muscle
Muscle connecting the zygomatic bone to the angle of the mouth; it assists in smiling and laughing.
