Tibia

The shin bone, the larger of the two bones in the lower leg.

Fibula

The smaller of the two bones in the lower leg, located next to the tibia.

Patella

Also known as kneecap; the largest sesamoid bone.

Phalanges

The bones of the toes.

Tarsals

The seven bones that make up the ankle.

Metatarsals

The five long bones in the foot between the tarsals and the phalanges.

Ilium

The largest part of the os coxae.

Ischium

The lower, back part of the hip bone.

Pubis

The front part of the os coxae.

Acetabulum

The socket in the pelvic bone for the head of the femur.

Greater sciatic notch

A large notch in the ilium for the passage of the sciatic nerve.

Lesser sciatic notch

A smaller notch located below the greater sciatic notch.

Anterior superior iliac spine

A bony projection on the ilium.

Pubic symphysis

The joint where the left and right pubic bones meet.

Iliac crest

The superior border of the ilium.

Ischial tuberosity

The part of the ischium that bears weight when sitting.

Obturator foramen

A large opening created by the ischium and pubis.

Ramus of pubis

The part of the pubic bone that helps form the obturator foramen.

Pelvic inlet

The upper opening of the true pelvis.

Pelvic outlet

The lower opening of the true pelvis.

Sacrum

The triangular bone at the base of the spine that connects the pelvis.

Coccyx

The small bone at the base of the vertebral column, also known as the tailbone.

Femoral head

The rounded upper end of the femur that fits into the acetabulum.

Greater trochanter

A large bony prominence on the femur for muscle attachment.

Lesser trochanter

A small bony prominence on the femur, located on the medial side.

Medial condyle

The rounded end of the femur that articulates with the tibia on the inner side.

Lateral condyle

The rounded end of the femur that articulates with the tibia on the outer side.

Intercondylar fossa

The space between the medial and lateral condyles.

Patellar surface

The smooth surface on the femur where the patella articulates.

Sacroiliac joint

The joint between the sacrum and ilium.

Anterior inferior iliac spine

A bony projection on the ilium located below the anterior superior iliac spine.

Interpubic disc

The cartilage that separates the pubic bones.

Base of sacrum

The broad upper part of the sacrum.

Pelvic fossa

The hollow space in the pelvis formed by the pelvic bones.

Coxal bone

Another name for the os coxae.

Phalanx

One of the bones in the fingers or toes.

Calcaneus

The heel bone, a tarsal bone.

Cuboid

A tarsal bone located on the lateral side of the foot.

Medial cuneiform

A wedge-shaped bone in the foot located medially.

Intermediate cuneiform

A wedge-shaped bone in the foot located between the medial and lateral cuneiform.

Lateral cuneiform

A wedge-shaped bone in the foot located laterally.

Navicular

A tarsal bone located in front of the talus.

Talus

The tarsal bone that articulates with the tibia and fibula.

Trochlear surface of talus

The surface on the talus that articulates with the tibia.

Tuberosity of calcaneus

A projection on the calcaneus for muscle attachment.
