Anatomy and Physiology - Appendicular Skeleton

Flashcards covering vocabulary related to the appendicular skeleton.

Appendicular Skeleton

Limbs and girdles attaching them to the axial skeleton, enabling movement and articulation.

Pectoral Girdle

Clavicle and scapula; attaches the upper limb to the axial skeleton.

Clavicle

S-shaped collar bone, articulating with the sternum and scapula.

Scapula

Site for muscle attachments; connects upper limb to the axial skeleton.

Upper Limb Regions

Arm, forearm, wrist, palm, and fingers.

Humerus

Largest upper limb bone; articulates with glenoid cavity, radius, and ulna.

Ulna

Medial forearm bone; articulates with humerus and carpals.

Radius

Lateral forearm bone; articulates with humerus and carpals.

Carpals

Eight bones of the wrist; form carpal tunnel.

Metacarpals

Five bones of the palm.

Phalanges (hand)

Three bones per finger, two in the thumb.

Pelvic Girdle

Two coxal bones; supports vertebral column, protects viscera, attaches lower limbs.

Coxal Bone Landmarks

Articulates with pubic symphysis and sacrum; includes acetabulum and obturator foramen.

Ilium

Largest part of hip bone; site for muscle attachment.

Ischium

Inferior, posterior hip bone part.

Pubis

Anterior, inferior hip bone part.

False Pelvis

Superior to pelvic brim.

True Pelvis

Inferior to pelvic brim; includes pelvic inlet and outlet.

Male Pelvis

Larger, heavier, narrower pelvis.

Female Pelvis

Wider, shallower pelvis.

Lower Limb Regions

Thigh, kneecap, leg, ankle, foot, and toes.

Femur

Longest, heaviest bone; articulates with acetabulum, tibia, and patella.

Patella

Sesamoid bone anterior to knee joint.

Tibia

Medial leg bone; articulates with femur.

Fibula

Lateral leg bone; articulates with talus.

Tarsals

Seven ankle bones; talus articulates with tibia and fibula, calcaneus forms heel.

Metatarsals

Five foot bones.

Phalanges (foot)

Three bones per toe, two in the big toe.
