Skeletal system

An adult's skeleton contains

206 bones

Children's skeletons contain more bones because some of them including those of the skull

fuse together as they grow up

What is the soft spot of a newborn baby's skull

fontanelle

The fontanelle

it's an unique feature that's important for the normal growth and development of your baby's brain and skull

Each end bone is called

epiphysis

While the middle bone is called a

diaphysis

Osteoblasts

bone forming cells

Osteoclasts are

resorb or break down bone

Osteocytes

mature bone cells

hematopoiesis (hemopoiesis)

Red bone marrow produces red and white blood cells

Red bone marrow is found in

hollow space inside of bones

Bands of strong connective tissue hold bones together

Ligaments

They are bands of tissue that connect the ends of a muscle to your bone

Tendons

It's a tough membrane that covers and protects the outside of the bone

Periosteum

The core, inner layer of the bone is softer than compact bone. It has small holes called pores to store marrow

Spongy bone

It is a viscous liquid located in the joints to limit the friction between bones and to absorb impact

Synovial fluid

Tissue that protects your bones and joints. It surrounds the ends of your bones and cushions the spaced in your joints where bones meet

cartilage

Process in which cartilage is transformed into hard bone tissue

Ossification

Bone remodeling process

resting, resorption, formation, mineralization

resting

osteocytes are just there

resorption

bones are reabsorbed by osteoclasts (break down and digest the bone)

formation

remade by osteoblasts (formation and building of a new bone)

mineralization

osteocytes absorb as much as calcium as possible to make the bone hard

Harvesian canal

Along, longevity

Volkmann's canal

Horizontally, transversal, across
