A specialized CONNECTIVE TISSUE that is the main constituent of the SKELETON. The principle cellular component of bone is comprised of OSTEOBLASTS; OSTEOCYTES; and OSTEOCLASTS, while FIBRILLAR COLLAGENS and hydroxyapatite crystals form the BONE MATRIX.
The constricted portion of the thigh bone between the femur head and the trochanters.
VERTEBRAE in the region of the lower BACK below the THORACIC VERTEBRAE and above the SACRAL VERTEBRAE.
The longest and largest bone of the skeleton, it is situated between the hip and the knee.
A large multinuclear cell associated with the BONE RESORPTION. An odontoclast, also called cementoclast, is cytomorphologically the same as an osteoclast and is involved in CEMENTUM resorption.
The largest of the TARSAL BONES which is situated at the lower and back part of the FOOT, forming the HEEL.
Bone-forming cells which secrete an EXTRACELLULAR MATRIX. HYDROXYAPATITE crystals are then deposited into the matrix to form bone.
The spinal or vertebral column.
The projecting part on each side of the body, formed by the side of the pelvis and the top portion of the femur.
The largest of three bones that make up each half of the pelvic girdle.
The outer shorter of the two bones of the FOREARM, lying parallel to the ULNA and partially revolving around it.
The region of the HAND between the WRIST and the FINGERS.
The second longest bone of the skeleton. It is located on the medial side of the lower leg, articulating with the FIBULA laterally, the TALUS distally, and the FEMUR proximally.
A group of twelve VERTEBRAE connected to the ribs that support the upper trunk region.
The joint that is formed by the articulation of the head of FEMUR and the ACETABULUM of the PELVIS.
Mature osteoblasts that have become embedded in the BONE MATRIX. They occupy a small cavity, called lacuna, in the matrix and are connected to adjacent osteocytes via protoplasmic projections called canaliculi.
