What is the marrow cavity lined with?

What is the marrow cavity lined with?

The medullary cavity is described as a hollow area in the diaphysis part of the bone and is lined by a delicate membrane called endosteum.

What marrow is found in spongy bone?

Spongy bone is found mostly at the ends of bones and contains red marrow.

What is the membrane that lines the marrow cavity and covers spongy bone called?

The endosteum (plural endostea) is a thin vascular membrane of connective tissue that lines the inner surface of the bony tissue that forms the medullary cavity of long bones. This endosteal surface is usually resorbed during long periods of malnutrition, resulting in less cortical thickness.

Does spongy bone have gaps filled with marrow?

The medullary cavity, live the spaces in spongy bone, is filled with bone marrow. Figure 6.2. The structural features of compact bone. Figure 6.3 The structural features of spongy bone.

How are spongy and compact bone different?

Compact bone is dense and composed of osteons, while spongy bone is less dense and made up of trabeculae.

What is found in spongy bone?

Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow. The canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply.

What is produced inside the bone marrow of spongy bone quizlet?

Terms in this set (45) A highly vascularized connective tissue located in microscopic spaces between trabeculae of spongy bone tissue. Produces red blood cells, red platelets, and white blood cells. Yellow bone marrow consists mainly of adipocytes, which store triglycerides.

Is there spongy bone in the medullary cavity?

Located in the main shaft of a long bone (diaphysis) (consisting mostly of compact bone), the medullary cavity has walls composed of spongy bone (cancellous bone) and is lined with a thin, vascular membrane (endosteum). that holds the bone marrow.

Why is spongy bone so spongy?

Spongy bone is softer and weaker than compact bone, but is also more flexible. It is characterized by a lattice-like matrix network called trabeculae (Latin for little beam) that gives it its spongy appearance.

What causes spongy bones?

Osteomalacia, or “soft bones, ” develops because of a lack of vitamin D. Maintaining your levels of vitamin D and calcium is essential for bone health.

Where does red bone marrow fill the space between spongy bones?

Red bone marrow fills the spaces between the spongy bone in some long bones. Each epiphysis meets the diaphysis at the metaphysis. During growth, the metaphysis contains the epiphyseal plate, the site of long bone elongation described later in the chapter.

What is the difference between compact bone and spongy bone?

Compact Bone Compact bone is the denser, stronger of the two types of osseous tissue (Figure 6.3.6). It makes up the outer cortex of all bones and is in immediate contact with the periosteum. In long bones, as you move from the outer cortical compact bone to the inner medullary cavity, the bone transitions to spongy bone.

What is the lining of the medullary cavity called?

Click to see full answer. Also question is, what is the lining of the medullary cavity called? the inner lining of the medullary cavity is called the. endosteum. what tissue (s) is present in a typical long bone. blood tissue, cancellous bone, compact bone, dense fibrous, and hyaline cartilage.

What is the blood and nerve supply to the spongy bone?

Blood and Nerve Supply The spongy bone and medullary cavity receive nourishment from arteries that pass through the compact bone. The arteries enter through the nutrient foramen (plural = foramina), small openings in the diaphysis (Figure 6.3.10).
