What is a major Submembranous site of osteoclasts?

What is a major Submembranous site of osteoclasts?

major submembranous sites of osteoclasts. endosteum and periosteum.

What is Intramembranous and endochondral ossification?

In intramembranous ossification, bone develops directly from sheets of mesenchymal connective tissue. In endochondral ossification, bone develops by replacing hyaline cartilage. Activity in the epiphyseal plate enables bones to grow in length. Remodeling occurs as bone is resorbed and replaced by new bone.

What are the types of ossification?

There are two types of bone ossification, intramembranous and endochondral. Each of these processes begins with a mesenchymal tissue precursor, but how it transforms into bone differs.

Which type of cartilage is the most effective at resisting compression?

Hyaline cartilage is highly resistant to compression. It does NOT always have a perichondrium (as in articular cartilage). Its matrix consists of type II collagen and hyaluronan, and it is NOT found in the pinna of the ear and epiglottis (elastic cartilage is found there).

Which type of bone has the least amount of spongy bone?

Long bones
Long bones have the least amount of spongy bone relative to their total volume.

What are the 2 types of bone What is the difference between the two?

Compact and spongy bones are considered the two basic structural bone types. The best explanation of the difference between the two is that the spongy bones in terms of area can be found at the head part of long bones. Compact bones are also known as cortical bones. Spongy bones are also known as cancellous bones.

Can bones repair themselves?

Our bones can withstand a lot of physical force and are also very flexible. However, if the force is too great, bones can break. Provided that the conditions are right for the break to heal completely, a broken bone or fracture can actually repair itself.

What are the 6 steps of endochondral ossification?

Terms in this set (6)

  • Cartilage enlarges; Chondrocytes die.
  • blood vessels grow into perichondrium; cells convert to osteoblasts; shaft becomes covered with superficial bone.
  • more blood supply and osteoblasts; produces spongy bone; formation spreads on shaft.
  • Osteoclasts create medullary cavity; appositional growth.

What is the last bone to ossify?

Ossification (or osteogenesis) in bone remodeling is the process of laying down new bone material by cells named osteoblasts….Ossification.

Time period Bones affected
23 to 26 years Bone of the sternum, clavicles, and vertebrae become completely ossified

What heals faster bone or cartilage?

Chondrocytes rely on diffusion to obtain nutrients as, unlike bone, cartilage is avascular, meaning there are no vessels to carry blood to cartilage tissue. This lack of blood supply causes cartilage to heal very slowly compared with bone.
