What is the cavity inside the middle of the bone called?
medullary cavity: The medullary cavity, also known as the marrow cavity, is the central cavity of bone shafts where red bone marrow and/or yellow bone marrow (adipose tissue) is stored.
What is filled with cavities of bone?
FMA. 83698. Anatomical terminology. The medullary cavity (medulla, innermost part) is the central cavity of bone shafts where red bone marrow and/or yellow bone marrow (adipose tissue) is stored; hence, the medullary cavity is also known as the marrow cavity.
What cavity stores fat for the bone?
Bone marrow fat (BMF) is located in the bone marrow cavity and accounts for 70% of adult bone marrow volume.
What is the type of tissue that fills spaces in bones?
Spongy bone tissue
Spongy bone tissue fills part or all of the interior of many bones. As its name suggests, spongy bone is porous like a sponge, containing an irregular network of spaces. This makes spongy bone much less dense than compact bone.
What is the medullary cavity?
The medullary cavity is the hollow part of bone that contains bone marrow. The bone marrow makes blood cells and stores fat. Spongy bone (also called cancellous bone) is made up of small, needle-like pieces of bone arranged like a honeycomb.
What fills the medullary cavity?
Inside the diaphysis is the medullary cavity, which is filled with yellow bone marrow in an adult. The outer walls of the diaphysis (cortex, cortical bone) are composed of dense and hard compact bone, a form of osseous tissue.
What are the rings formed by the osteocytes called?
The osteocytes are arranged in concentric rings of bone matrix called lamellae (little plates), and their processes run in interconnecting canaliculi.
What is the space in the center of the diaphysis called?
The hollow region in the diaphysis is called the medullary cavity, which is filled with yellow marrow.
What would you find in the marrow cavity of the diaphysis?
The hollow region in the diaphysis is called the medullary cavity, which is filled with yellow marrow. The walls of the diaphysis are composed of dense and hard compact bone. The wider section at each end of the bone is called the epiphysis (plural = epiphyses), which is filled with spongy bone.
What is the diaphysis function?
Terms in this set (19) Diaphysis. (middle of long bone) -Main shaft of longbone; hollow, cylindrical shape, thick, compact bone. Function: Provide strong support without cumbersome weight.
What is the microscopic lining of the medullary cavity called?
endosteum
The medullary cavity has a delicate membranous lining called the endosteum. The outer surface of bone, except in regions covered with articular cartilage, is covered with a fibrous membrane called the periosteum.
