2023年8月7日 · Bones support the weight of your body and give it shape. They help you move and protect your organs. Adults have between 206 and 213 bones.

Bones are classified by their shape. They may be long (like the femur and forearm), short (like the wrist and ankle), flat (like the skull), or irregular (like the spine). Primarily, they are referred to as long or short. There are 206 bones in the adult human skeleton.

2024年4月21日 · Understanding bone anatomy and physiology helps healthcare professionals treat skeletal conditions. Bone Structure. From a histological perspective, bones are highly specialized connective tissues that can remodel based on exogenous demand.

This section will examine the gross anatomy of bone first and then move on to its histology. A long bone has two main regions: the diaphysis and the epiphysis (Figure 6.3.1). The diaphysis is the hollow, tubular shaft that runs between the proximal and distal ends of the bone.

2025年1月23日 · Human skeleton, the internal skeleton that serves as a framework for the body. This framework consists of many individual bones and cartilages. There also are bands of fibrous connective tissue—the ligaments and the tendons—in …

2025年1月24日 · Bone, rigid body tissue consisting of cells embedded in an abundant hard intercellular material. Bone tissue makes up the individual bones of the skeletons of vertebrates. Its two principle components are collagen and calcium phosphate. Learn more about the composition and function of bone.

2011年2月4日 · Now that you know what bones do, let's take a look at what they're made of and their anatomy. Each bone in your body is made up of three main types of bone material: compact bone, spongy bone, and bone marrow.

Bone is actively constructed and remodeled throughout life by specialized bone cells known as osteoblasts and osteoclasts. Within any single bone, the tissue is woven into two main patterns: cortical and cancellous bone, each with a distinct appearance and characteristics.

2020年1月27日 · The skeletal system is formed of bones and cartilage, which are connected by ligaments to form a framework for the remainder of the body tissues. This article, the first in a two-part series on the structure and function of the skeletal system, reviews the anatomy and physiology of bone.
