Q

What does your Lamellae do?

A

It helps resist torsion & stress

28
Q

It holds your nerves & blood vessels (nourishment to the bone)

A

Central Canal

29
Q

These are tiny oblong spaces/gaps that houses your Osteocytes

A

Lacunae

30
Q

These are your mature bone cells.

A

Osteocytes Cells

31
Q

What do your bone cells do?

A

They monitor & maintain your blood matrix.

32
Q

What are 2 types of Osteocytes cells?

A

Osteoblasts & Osteoclasts cells

33
Q

This type of Osteocytes cells are known to be “Bone building makers” & they secret like glue.

A

Osteoblasts Cells

34
Q

What type of Osteocytes cells is known to be the “Bone Breakers” (process before producing a new bone)?

A

Osteoclasts Cells

35
Q

It is responsible for initiating Bone Remodeling

A

Osteocytes Cells

36
Q

This is known for its Resorption /tear-down process wherein, the Osteocytes release chemical signals & direct Osteoclasts to the site of the damage. Once they get there, they’ll secret a collagen-digesting enzyme & acidic hydrogen-ion that dissolves the calcium phosphate, releasing its components back in the blood.

A

Bone Remodeling Process

37
Q

What are the types of Fractures?

A

Closed (simple) & Open (compound) fractures.
