Spongy tissue is found
on the interior of the bone
, and compact bone tissue is found on the exterior.
Where is spongy bone located and what is its function?
This type of osseous tissue lies subjacent to the compact bone, and is made distinct by its spongy structure. It is found
at the ends of long bones
and in the vertebrae. It has low density and strength but has high surface area that allows room for blood vessels and marrow.
Where do you find compact and spongy bone?
Compact bones are the present in the outer layer of long bones
, while spongy bones are present in the middle of the long bones. The main difference between spongy and compact bones is their structure and function.
Where is spongy bone located and what kind of tissue is stored here?
Spongy Bone (Cancellous Bone)
Spongy bone is supplied by fewer and larger vessels than compact bone. These vessels perforate the outer compact layer and are distributed into the spongy portion of bone, which is filled with
marrow
. Bone marrow is tissue found in long bones, like the femur, that contains stem cells.
What is spongy bone examples?
Spongy Bone Definition
Spongy bone is usually located at the ends of the long bones (the epiphyses), with the harder compact bone surrounding it. It is also found inside the vertebrae, in the ribs, in the skull and in the bones of the joints.
What is spongy bone responsible for?
Cancellous bone makes up about 20 percent of the human skeleton,
providing structural support and flexibility without
the weight of compact bone. It is found in most areas of bone that are not subject to great mechanical stress.
What are 2 types of bone tissue?
There are two types of bone tissue:
compact and spongy
. The names imply that the two types differ in density, or how tightly the tissue is packed together. There are three types of cells that contribute to bone homeostasis.
What is the major difference between compact and spongy bone?
Compact bone tissue is composed of osteons and forms the external layer of all bones. Spongy bone tissue
is composed of trabeculae and forms the inner part of all bones
.
Why do we need both compact and spongy bone?
They are the bone tissues in animals that provide shape and support to the body. Both types of bones contain osteoblasts and osteoclasts that are necessary for creating bones. Both compact and spongy bones contain
proteins like collagens and osteoids
, which mineralize to help in bone formation.
What type of cell produces bone tissue?
OSTEOBLASTS
are the cells that form new bone. They also come from the bone marrow and are related to structural cells. They have only one nucleus. Osteoblasts work in teams to build bone.
What is bone tissue composed of?
Bone is made up of
compact tissue (the hard, outer layer) and cancellous tissue (the spongy, inner layer that contains red marrow)
. Bone tissue is maintained by bone-forming cells called osteoblasts and cells that break down bone called osteoclasts.
Which of these tissue is present in a typical long bone?
| Long bone | FMA 7474 | Anatomical terms of bone |
|---|
How is spongy bone formed?
The non-mineralized portion of the bone or osteoid continues to form around blood vessels
, forming spongy bone. Connective tissue in the matrix differentiates into red bone marrow in the fetus. The spongy bone is remodeled into a thin layer of compact bone on the surface of the spongy bone.
How does spongy bone get nutrients?
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.
Is spongy bone the same as bone marrow?
Spongy bone is found mostly at the ends of bones and contains
red marrow
. Bone marrow is found in the center of most bones and has many blood vessels.
What is the source of bone tissue Histogenesis?
Osteoblasts originate from
local pluripotent mesenchymal stem cells
, either bone marrow stromal stem cells (endosteum) or connective tissue mesenchymal stem cells (periosteum).
