The composition of long bones is both spongy and compact bone. the long bone has at both ends a head or knob which is spongy bone (more holes, less sturdy). At the center of the knob or head called the epiphyses where red blood cells are produced. The epiphyses has what is known as an epiphyseal plate or growth plate in a transverse position and is made of cartilage. This plate can be measured in children to determine if hormone treatments are necessary to promote bone growth in children who might otherwise be below average in bone growth or development. The stick or shaft portion of long bones between the two epiphyses is known as the diaphysis. The diaphysis is hollow but its walls are made of compact bone (less holes, sturdier). In the hollow portion or medullary cavity as it's known of the diaphysis of long bones is where yellow marrow sits which can be converted to red marrow when the body has a deficit. Yellow marrow is yellow in color. On the ends of long bones you will find cartilage which serves to protect bones during movement.
What else can I help you with?
Medullary cavity function?
The medullary cavity is a space within the diaphysis (shaft) of a long bone. It contains yellow bone marrow, which stores fats and serves as an energy reserve. Additionally, the medullary cavity provides space for blood vessels and nerves to pass through the bone.
Do osteoblasts from the medullary cavity migrate to the fracture site?
Yes, osteoblasts from the medullary cavity can migrate to the fracture site to participate in bone healing. When a bone fractures, osteoblasts are recruited from various sources, including the medullary cavity, to produce new bone tissue and facilitate the repair process.
What is another name for the medullary cavity of the bone?
Another name for the medullary cavity of the bone is the marrow cavity.
What tissue covers the medullary cavity?
The tissue that covers the medullary cavity is called endosteum. This thin membrane lines the inner surface of the bone, providing a surface for bone growth, repair, and remodeling. It also contains osteoblasts and osteoclasts, which are essential for bone maintenance and metabolism.
What is the medullary cavity lined with?
The medullary cavity is lined with endosteum, a connective tissue membrane that contains osteoprogenitor cells responsible for bone growth and repair. It helps to maintain the structural integrity of the bone and plays a role in bone remodeling.
Thin layer of connective tissue lined with the medullary cavity of a long bone?
Endosteum is a thin layer of connective tissue that lines the medullary cavity of a long bone. It contains osteoprogenitor cells that differentiate into osteoblasts to aid in bone growth and repair. Its function is to support bone growth and remodeling by providing a surface for bone-forming cells.
Does bone have a medullary cavity?
true
What does the medullary cavity do in the bone?
the medullary cavity in the bone is located in the middle of a long bone and yellow marrow is located here (only seen in adults).
The location of fat in adult bones are?
Fat, also called adipose tissue when it is stored in the body, can be found in the medullary cavity of long bones as yellow bone marrow.
What is another word for a bone cavity?
Medullary Cavity or bone cavity is also a word called fossa.
What is the function of the medullary cavity?
The medullary cavity is the central cavity of bone shafts. This is where red and yellow bone marrow are stored. The medullary cavity is also involved in the formation of red and white blood cells.
What name is given to the cavity that runs through the diaphysis?
The cavity that runs through the diaphysis of a long bone is called the medullary cavity. It contains yellow or red bone marrow, depending on the bone and the individual's age.
