Anatomy of Long Bones Quiz

Medulla is not a component of a long bone; components include diaphysis, epiphysis, metaphysis, periosteum, and marrow.

Red bone marrow primarily functions in the production of red blood cells through hematopoiesis.

The end of a long bone is called the epiphysis, which articulates with other bones to form joints.

Osteoclasts are bone cells responsible for bone resorption, breaking down bone tissue during remodeling.

The dense outer layer of a long bone is known as cortical bone, providing strength and support.

Longitudinal bone growth is facilitated by the epiphyseal plate, a cartilaginous region between the diaphysis and epiphysis.

The epiphyses of long bones contain spongy bone tissue, which provides structural support with a trabecular arrangement.

The periosteum functions in bone nourishment, attachment of tendons/ligaments, and participation in bone repair, but not in the production of red blood cells.

Articular cartilage in long bones provides a smooth surface, reducing friction and facilitating smooth joint movement.

Yellow bone marrow in long bones primarily functions in fat storage.

Parathyroid hormone (PTH) regulates calcium levels in the blood and influences bone metabolism by stimulating osteoclast activity.

The epiphysis is a common site for harvesting bone marrow, particularly red bone marrow.

The process of bone formation is termed ossification, involving the deposition of mineralized matrix by osteoblasts.

Osteoblasts are responsible for secreting the organic components of the bone matrix, contributing to bone formation.

Lamellae is not a component of the Haversian system; components include Haversian canals, osteons, and concentric lamellae.
