Anatomy of a Long Bone, Bone cells

Protects the ends of bones from wearing down

Articular Cartilage

Enters and exits bone through the nutrient foramen

Blood vessel

Full of red marrow

Spongy bone

How newly made blood cells leave the bone (not the hole)

Blood Vessel

The knobby end of your femur at the hip end

Proximal epiphysis

The long shaft in the middle of the bone

Diaphysis

Makes up the diaphysis and outside of long bones

Compact bone

Site of hemopoiesis

Red marrow

When this gets destroyed/used up, you get arthritis

Articular cartilage

The knobby end of your femur at the knee end

Distal epiphysis

Hollow space inside the diaphysis

Medullary cavity

Medullary cavity is inside this part of the bone (not type of bone; not layer)

Diaphysis

Full of stem cells

Red marrow

Name literally means “joint cartilage”

articular cartilage

Layer that lines the medullary cavity

Endosteum

Layer that lines the outside of the bone

Periosteum

Growth plates

Epiphyseal plate

Delivers nutrients and oxygen to the bone cells

Blood vessels

The knobby end of your humerus at the shoulder end

Proximal epiphysis

the knobby end of your humerus at the elbow end

Distal epiphysis

Name literally means “around bone”

Periosteum

Name literally means “inside bone”

Endosteum

Type of bone found inside the epiphyses

Spongy bone

Little hole in the bone that the blood vessel goes through

Nutrient foramen

made of cartilage, but ossify to bone each time you grow

Epiphyseal plate

Space full of yellow marrow

Medullary cavity

At age 25, fully ossifies

Epiphyseal plate

Means “Bone produce”

osteogenic cell

means “bone bud/sprout”

osteoblast

means “bone cell”

osteocyte

means “bone break”

osteoclast

helps to break down old bone

osteoclast

this type of bone cell is mitotic

osteogenic cell

considered a “mature bone cell”

osteocyte

shaves away old bone when your bones are growing wider

osteoclast

NOT located in the periosteum

osteocyte

this type of bone cell becomes an osteocyte

osteoblast

Creates the matrix of bones

osteoblast

Cleans away dead bone after a fracture

osteoclast

Creates osteoblasts

osteogenic cell

located in the periosteum and endosteum

osteoblast, osteoclast, osteogenic cell

type of bone cell allows your bones to perform their daily functions

osteocyte

is a stem cell

osteogenic cell

gets buried and become another type of bone cell

osteoblast

located on epiphyseal plates and on the periosteum

osteoblast

located inside spongy and compact bone

osteocyte

creates the osteoid of bones

osteoblast
