Anatomical Axes
• An axis is a straight line around which an object rotates. • Horizontal Axes• Longitudinal Axes• Antero-posterior Axes-

The general rule is that the axis of rotation is always perpendicular to the plane of movement.

The Skeleton consists of 206 bones and is 14% of our total body weight.

Functions of the Skeletal System
-support -locomotion -protection -creation of RBC's and WBC's in the long bones -storage

Structure of the Skeletal System pg. 10 Axial Skeleton - 80 bones Appendicular Skeleton - 126 bones

Five types of Bones pg. 11 Long Bones- femur Short Bones- wrist Flat Bones- parietal bone Irregular Bones- vertebrae Sesamoid Bones- patella

Anatomy of a Long Bone
Friday, October 01, 2010 10:17 PM

While observing the long bone complete the following questions: 1. Identify the outstanding visual characteristics observed in the bone's exterior. Make qualitative observations with regard to the bone's size, shape, colour, texture, landmarks (bony projections, etc), attachments, density, openings, etc. 2. Draw a sketch of your bone and label the key features of the bone. 3. Describe each key feature below by completing the chart. Key Feature Cartilage Both ends of long bone Periosteum Covers the entire length of the bone Location Description Function

Allows smooth Allows smooth movement movement within within joints while protecting joints while protecting the end of bones the end of bones Name given to the outer connective tissue that covers entire length of bone Periosteum fibres and those of ligaments and tendons unite to connect bone to bone or muscle to bone

Medullary Cavity Found inside the shaft of the bone

Found inside the shaft of the bone and is filled with red and yellow bone marrow

Red marrow is where bone formation occurs and yellow marrow is made up of adipose cells and connective tissue that has no role in bone formation

Compact Bone

More dense part of the bone. Thickest along the diaphysis

More dense part of the Responsible for the bone's bone structural integrity

Cancellous Bone Filled with marrow in Filled with marrow in its matrix or small its matrix or small cavity like spaces cavity like spaces

Epiphysis

Located at the very Outer surface made up ends of the long bone of compact bone, and part that articulates with another bone is covered with cartilage The shaft The thickest part of the long bone

Diaphysis
