The small dip at the top of the sternum (breastbone), located just below the neck.
Xiphoid Process
The small, pointed piece of cartilage at the bottom of the sternum.
Scapula
The shoulder blade; a flat bone on the upper back that helps form the shoulder joint.
Sacrum
A large, triangular bone at the base of the spine, between the hips.
Coccyx
The small tailbone at the very bottom of the spine.
Iliac bones
The large, curved bones that form the sides of the pelvis.
Pubic Symphysis
The joint where the two pubic bones meet at the front of the pelvis.
Acetabulum
The socket in the pelvis that holds the head of the femur (thigh bone), forming the hip joint.
Humerus
The upper arm bone, extending from the shoulder to the elbow.
Raduis
One of the two bones in the forearm; it is on the lateral side

The other bone in the forearm, located more median
Carpal Bones

Metacarpals

The thigh bone; the longest and strongest bone in the body.
Tibia
The shin bone; the larger, stronger bone in the lower leg.
Fibula
The smaller bone in the lower leg, located lateral to the tibia
Patella

malleolus
The bony bumps on each side of the ankle, formed by the tibia and fibula.
Phalanges
The bones of the fingers and toes.
Tarsels
The seven bones that make up the ankle and the back part of the foot.
Ball and socket joint
A type of joint where a round ball-like end of one bone fits into a cup-like socket of another bone, allowing for a wide range of motion (e.g., the shoulder or hip joint).
Orbits
The bony sockets in the skull that house the eyes.
