What type of tissue is compact and spongy bone?

What type of tissue is 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. Four types of cells compose bony tissue: osteocytes, osteoclasts, osteoprogenitor cells, and osteoblasts.

What are the other names for compact and spongy bone?

• Compact Bone (Cortical Bone) Compact bone is dense bone tissue found on the outside of a bone.
• Spongy Bone (Cancellous Bone) “Cancellous” makes it sound so negative, doesn’t it?
• Bone Marrow and Stem Cells.

What is compact bone tissue called?

compact bone, also called cortical bone, dense bone in which the bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces (lacunae) that contain the osteocytes, or bone cells.

What is compact bone 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.

What do both spongy and compact bone have in common?

Similarities Between Compact and Spongy Bone Both compact and spongy bones are made up of osseous tissue, which is a type of connective tissue that makes the bone. Both compact and spongy bones are involved in the movement of the body. Both compact bone and spongy bones contain calcium.

What are cancellous bones?

Cancellous bone is the meshwork of spongy tissue (trabeculae) of mature adult bone typically found at the core of vertebral bones in the spine and the ends of the long bones (such as the femur or thigh bone).

What is cancellous tissue?

Cancellous tissue, also known as cancellous bone, spongy bone or trabecular bone, is characterized by its spongy, porous, honeycomb-like structure and is typically found at the ends of long bones. Compact tissue is also known as hard bone, compact bone or compact cortical bone. Source: GreenFacts.

What is axial and appendicular skeleton?

Your axial skeleton is made up of the bones in your head, neck, back and chest. Your appendicular skeleton is made up of everything else — the bones that attach (append) to your axial skeleton. Your appendicular skeleton includes the bones in your shoulders, pelvis and limbs, including your arms, hands, legs and feet.

What is spongy bone?

Spongy (cancellous) bone is lighter and less dense than compact 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 compact tissue?

Mature bones are made up of three types of tissue: compact tissue (the hard outer portion of most bones); cancellous tissue (spongy tissue inside the bones that contains bone marrow, which makes blood cells); and subchondral tissue (smooth bone tissue of the joints).

What is cortical and cancellous bone?

A Cortical and Cancellous Bone Cortical bone is a dense tissue that contains less than 10% soft tissue. Cancellous or spongy bone is made up of trabecules shaped as plates or rods interspersed between bone marrow that represents more than 75% of the cancellous bone volume.

What is appendicular bones?

The appendicular skeleton is one of two major bone groups in the body, the other being the axial skeleton. The appendicular skeleton is comprised of the upper and lower extremities, which include the shoulder girdle and pelvis.

What is another name for spongy bone?

Spongy (Cancellous) Bone.

What are axial and appendicular bones?

Is spongy bone and compact bone the same?

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