Skeletal System Vocab

Combined from both Mr. Snyder and ACE

Yellow Bone Marrow

Contains adipose tissue

Red Bone Marrow

Where blood production takes place, Hematopoiesis.

Long Bones

A cylinder, longer bone than it is wide. Examples includes humerus.

Short Bones

Blob shaped bones, in the carpals and tarsals

Irregular Bones

More complex chapes than other bone types. Includes the vertebrae,

Sesamoid Bones

Small bones that protects tendons from external stress like the patella.

Flat Bones

Thin bomems that are often curved, mainly for protection like the ribs.

Compound Fracture

It’s an open, seethrough break from the exterior.

Transverse Fracture

A straight break in the bone

Spiral Fracture

Bone is spart because of a twisting motion.

Comminuted Fracture

A large break leads into small parts of bone coming off.

Impacted Fracture

When a bone is driven into the other, leading to breaking.

Greenstick Fracture

A small part of the bone is broken.

Ecchymosis

Swelling in the bones.

Edema

Swelling

Oblique Fracture

Diagonal break

Avulsion Fracture

When a muscle pull leads to a fracture in the bone

Blowout Fracture

Break in the eye socket.

Longitudinal Fracture

An entire bone split.

Osteoclast

The ones that destory bone cells.

Osteoblasts

The cells that repairs bones.

Inflamation

Edma, swelling in the injured site. Ends 2-3 weeks after injury.

Soft Callus

The start of physical regrowth. Continues for four weeks after stage 1.

Hard Callus

A bridge has been made in the injured site. Usually around four weeks after the last cycle.

Remodeling

Building up the final bone. Starts around four to eight weeks after the last cycle, but is continious over many of years.

Diaphysis

The “shaft” of a long bone

Epiphysis

The ends of a long bone,

Periosteum

The outer layer of all bones

Compact Bone

A second to inner layer of bone.

Medullary Cavity

The cavity where Yellow Bone Marrow is in.

Epiphyseal Plate

The growth plate.

Eccymosis

Discoloration

Creppitation

Crunching
