Chapter 8: The Skeletal System 3 - Appendicular Skeleton

Practice flashcards covering the terminology, structures, and articulations of the upper and lower appendicular skeleton based on the Chapter 8 lecture notes.

Tubercle

A small rounded process, projection or protuberance, especially on a bone, used for the function of connecting ligaments to muscle.

Articulation

A joint; an area where two bones are attached for the purpose of motion of body parts.

Tuberosity

A rough area or protrusion on a bone.

Condyle

A rounded protuberance at the end of some bones, forming an articulation with another bone.

Pectoral Girdle

Supports the arms and links them to the axial skeleton; consists of the clavicle (collar bone) and scapula (shoulder blade).

Sternoclavicular joint

The articulation between the sternum and the clavicle.

Acromioclavicular joint

The articulation between the scapula and the clavicle.

Glenohumeral joint

The articulation between the scapula and the humerus.

Sternal end of the clavicle

The rounded end of the clavicle.

Acromial end of the clavicle

The flatter end of the clavicle.

Scapula

A triangular plate that covers over ribs $2$ through $7$ and glides over the posterior rib cage.

Glenoid Cavity

The structure of the scapula that articulates with the head of the humerus.

Coracoid process

A structure on the scapula that provides attachment for the tendons of the biceps brachii.

Brachium

The upper arm region containing the humerus bone.

Surgical Neck

A groove between the head and shaft on the proximal side of the humerus; often the site of breaks.

Capitulum

The lateral smooth circular shaped condyle of the humerus that articulates with the radius.

Trochlea

The medial smooth pulley like shaped condyle of the humerus that articulates with the ulna.

Radial tuberosity

The attachment point on the radius for the tendon of the biceps brachii.

Interosseous membrane

A fibrous membrane that connects the radius to the ulna and the tibia to the fibula along most of the shaft of each bone.

Manus

The hand, which contains $27$ bones including $8$ carpals, $5$ metacarpals, and $14$ phalanges.

Acetabulum

The hip socket where the femur articulates with the pelvic girdle.

Obturator foramen

An opening in the pelvic girdle that is closed over by a ligament.

Greater Trochanter

A rough process near the neck of the femur that serves as an attachment site for hip muscles.

Tibia

The weight bearing bone of the crural region.

Fibula

A bone in the crural region that supports the ankle.

Medial Malleolus

The ankle bone of the tibia.

Lateral Malleolus

The ankle bone of the fibula.

Tarsal Region

The ankle, consisting of $7$ tarsal bones.
