- Structure of a Typical Long Bone Long bones have a tubular bone shaft, consisting of a bone collar surrounding a hollow medullary cavity, which is filled with yellow bone marrow in adults. Epiphyses are at the ends of the bone, and consist of internal spongy bone covered by an outer layer of compact bone.The epiphyseal line is located between the epiphyses and diaphysis, and is a remnant of the epiphyseal plate. The external surface of the bone is covered by the periosteum.The internal surface of the bone is lined by a connective tissue membrane called the endosteum.he epiphyseal line is located between the epiphyses and diaphysis, and is a remnant of the epiphyseal plate.

- Compact bone is the solid, hard, outside part of the bone. This type of bone makes up the most of the human skeleton. It looks like ivory and is extremely strong. Holes and channels run through it, carrying blood vessels and nerves from the periosteum, the bone's outer membrane covering.

- All long bones have an area called the epiphysis, which is the rounded end of the bone. The long, middle part (or shaft) of the bone is the diaphysis; the area where the bone gets wider at its end is the metaphysis. In growing kids, growth plates sit between the metaphysis and the epiphysis. Growth plates are at the end of long bones, and grow in length. They're made up of cartilage, a rubbery, flexible material (the nose, for instance, is made of cartilage).

Anatomical terms of bone However, the term describes the shape of a bone, not its size which is relative. Long bones are found in the arms (humerus, ulna, radius) and legs (femur, tibia, fibula), as well as in the fingers (metacarpals, phalanges) and toes (metatarsals, phalanges). condyle (/ˈkɒndəl/ or /ˈkɒndaɪl/ ; is the round prominence at the end of a bone, most often part of a joint-an articulation with another bone. The epicondyle refers to a projection near a condyle, particularly the medial epicondyle of the humerus.

Human skeleton The human skeleton can be divided into the axial skeleton and the appendicular skeleton. The axial skeleton is formed by the vertebral column, the rib cage and the skull.The appendicular skeleton, which is attached to the axial skeleton, is formed by the pectoral girdle, the pelvic girdle and the bones of the upper and lower limbs.he human skeleton is the internal framework of the body. It is composed of 270 bones at birth – this total decreases to 206 bones by adulthood after some bones have fused together. The bone mass in the skeleton reaches maximum density around age 30.

What Are the Structural Parts of the Long Bones in the Body? Metaphysis. Between the ephiphysis cap and the long shaft of the diaphysis is a wide section of bone called the metaphysis. The metaphysis transfers load and stress from the joints at the ephphysis into the longer and stronger diaphysis.The metaphyses are also important for bone growth.edullary Cavity. Long bones all have a long cavity inside the diaphysis called the medullary cavity. This cavity is filled with red bone marrow in children, which transitions to yellow bone marrow as they grow to become adults.

The vertebrate skeleton Skeleton - The vertebrate skeleton: In vertebrates the adult skeleton is usually formed of bone or cartilage—living substances that grow with the animal, in contrast to the many types of invertebrate skeleton that do not grow or are dead secretions, deposits, or crystals.

Skeletal System: Bones, Joints, Cartilage, Ligaments, Bursae As the baby grows, some of the bones fuse such as the bones in the skull and the pelvis. Most girls and women have smaller skeletons than boys and men of the same age. There are two main parts of the skeleton—the axial skeleton and the appendicular skeleton. The Axial Skeleton. The axial skeleton (trunk) is made up of the 80 bones in our upper body.

Divisions of the Skeleton The adult human skeleton usually consists of 206 named bones. These bones can be grouped in two divisions: axial skeleton and appendicular skeleton. The 80 bones of the axial skeleton form the vertical axis of the body. They include the bones of the head, vertebral column, ribs and breastbone or sternum.The appendicular skeleton consists of 126 bones and includes the free appendages and their attachments to the axial skeleton.hese bones can be grouped in two divisions: axial skeleton and appendicular skeleton.

Overview Overview. Bone marrow is the soft, spongy, gelatinous tissue found in the hollow spaces in the interior of bones. The average weight of this tissue is about 4% of the total body weight, or 2.6 kg in an adult weighing 65 kg.Progenitor cell (stem cell) lines in the bone marrow produce new blood cells and stromal cells.verview.

Bone marrow Bone marrow is the flexible tissue in the interior of bones. In humans, red blood cells are produced by cores of bone marrow in the heads of long bones in a process known as hematopoiesis.On average, bone marrow constitutes 4% of the total body mass of humans; in an adult weighing 65 kilograms (143 lb), bone marrow typically accounts for approximately 2.6 kilograms (5.7 lb).he two types of bone marrow are red marrow (Latin: medulla ossium rubra), which consists mainly of hematopoietic tissue, and yellow marrow (Latin: medulla ossium flava), which is mainly made up of fat cells.

- The growth plate, also known as the epiphyseal plate or physis, is the area of growing tissue near the end of the long bones in children and adolescents. Each long bone has at least two growth plates: one at each end. The growth plate determines the future length and shape of the mature bone. When growth is complete--sometime during adolescence--the growth plates close and are replaced by solid bone.

Long bone The outer shell of the long bone is made of cortical bone also known as compact bone. This is covered by a membrane of connective tissue called the periosteum. Beneath the cortical bone layer is a layer of spongy cancellous bone.he long bones are those that are longer than they are wide. They are one of five types of bones: long, short, flat, irregular and sesamoid. Long bones, especially the femur and tibia, are subjected to most of the load during daily activities and they are crucial for skeletal mobility.

Histology of Bone Epiphysis. In the long bones, the epiphysis is the region between the growth plate or growth plate scar and the expanded end of bone, covered by articular cartilage. An epiphysis in a skeletally mature person consists of abundant trabecular bone and a thin shell of cortical bone (see the image below).piphysis.

Skeleton There are 206 bones in the adult human skeleton, although this number depends on whether the pelvic bones (the hip bones on each side) are counted as one or three bones on each side (ilium, ischium, and pubis), whether the coccyx or tail bone is counted as one or four separate bones, and does not count the variable wormian bones between skull sutures.

Long bone The long bones of the human leg comprise nearly half of adult height. The other primary skeletal component of height are the vertebrae and skull. The outside of the bone consists of a layer of connective tissue called the periosteum. Additionally, the outer shell of the long bone is compact bone, then a deeper layer of cancellous bone (spongy bone) which contains in the medullary cavity the bone marrow.

Bone In the human body at birth, there are over 270 bones, but many of these fuse together during development, leaving a total of 206 separate bones in the adult, not counting numerous small sesamoid bones. The largest bone in the body is the thigh-bone (femur) and the smallest is the stapes in the middle ear. protrusion from a bone can be called a number of terms, including a condyle, crest, spine, eminence, tubercle or tuberosity, depending on the protrusion's shape and location. In general, long bones are said to have a head, neck, and body.
