acromial process acromion of the scapula
acromioclavicular joint articulation between the acromion of the scapula and the acromial end of the clavicle
acromion flattened bony process that extends laterally from the scapular spine to form the bony tip of the shoulder
adductor tubercle small, bony bump located on the superior aspect of the medial epicondyle of the femur
anatomical neck line on the humerus located around the outside margin of the humeral head
ankle joint joint that separates the leg and foot portions of the lower limb; formed by the articulations between the talus bone of the foot inferiorly, and the distal end of the tibia, medial malleolus of the tibia, and lateral malleolus of the fibula superiorly
anterior border of the tibia narrow, anterior margin of the tibia that extends inferiorly from the tibial tuberosity
anterior inferior iliac spine small, bony projection located on the anterior margin of the ilium, below the anterior superior iliac spine
anterior superior iliac spine rounded, anterior end of the iliac crest
arm region of the upper limb located between the shoulder and elbow joints; contains the humerus bone
auricular surface of the ilium roughened area located on the posterior, medial side of the ilium of the hip bone; articulates with the auricular surface of the sacrum to form the sacroiliac joint

bicipital groove intertubercular groove; narrow groove located between the greater and lesser tubercles of the humerus
calcaneus heel bone; posterior, inferior tarsal bone that forms the heel of the foot
capitate from the lateral side, the third of the four distal carpal bones; articulates with the scaphoid and lunate proximally, the trapezoid laterally, the hamate medially, and primarily with the third metacarpal distally
capitulum knob-like bony structure located anteriorly on the lateral, distal end of the humerus
carpal bone one of the eight small bones that form the wrist and base of the hand; these are grouped as a proximal row consisting of (from lateral to medial) the scaphoid, lunate, triquetrum, and pisiform bones, and a distal row containing (from lateral to medial) the trapezium, trapezoid, capitate, and hamate bones
