Skeletal System
» Function˃ Provides frame and support for all systems and
organs.

Skeletal System»Ligaments˃ Connect bones together; tough tissue
» Tendons˃ Connects bones to muscles

Skeletal System
» Bone˃Attach muscles˃Means of movement˃Protect internal organs˃Storage of minerals
» Cartilage˃ Firm, flexible tissues that is not as hard as
bone

Skeletal System» Layers of Bone˃Periosteum
+ Outer layer+ Cushions the hard portion of the bone+ Repair of broken bones
![Page 7: SKELETAL SYSTEM](https://reader036.vdocument.in/reader036/viewer/2022062723/56813d5b550346895da7255f/html5/thumbnails/7.jpg)
Skeletal System» Layers of Bone˃Compact Bone
+ beneath periosteum+ layer of hard mineral matter + Calcium+ gives bones strength

Skeletal System» Layers of Bone˃Spongy Bone
+ Inside hard outer layer+ fills ends of bones+ lines hollow portions

Skeletal System» Layers of Bone˃Red marrow
+ inside cavities of spongy bone+ formation of red blood cells

Skeletal System» Types of Bone
˃ Long Bones + Longest+ Provide support and movement+ Levers
˃ Example -- legs, ribs, pelvic bones
![Page 14: SKELETAL SYSTEM](https://reader036.vdocument.in/reader036/viewer/2022062723/56813d5b550346895da7255f/html5/thumbnails/14.jpg)
Skeletal System» Types of Bone
˃ Short Bones + Smaller than long bones+ Joints+ Comfort and mobility
˃ Example -- feet and hands
![Page 15: SKELETAL SYSTEM](https://reader036.vdocument.in/reader036/viewer/2022062723/56813d5b550346895da7255f/html5/thumbnails/15.jpg)
Skeletal System» Types of Bone
˃ Irregular Bones+ Have an irregular shape+ Support and protect
˃ Example -- vertebrae
![Page 16: SKELETAL SYSTEM](https://reader036.vdocument.in/reader036/viewer/2022062723/56813d5b550346895da7255f/html5/thumbnails/16.jpg)
Skeletal System» Types of Bone
˃ Flat Bones + Thin and flat+ Protect organs
˃ Example -- skull
![Page 17: SKELETAL SYSTEM](https://reader036.vdocument.in/reader036/viewer/2022062723/56813d5b550346895da7255f/html5/thumbnails/17.jpg)
Skeletal System
» Joints˃Where different bones meet˃Classified by the way they move.

The Skeleton
» The skeleton is divided into two parts:˃ The axial skeleton protects the major organs of the
nervous, respiratory, and circulatory systems+ The axial skeleton consists of the skull, hyoid
bones, vertebral column, ribs, and sternum˃ The appendicular skeleton is the framework that
consists of the extremities, shoulder, and pelvic girdle
+ Appen means to add or hang+ The appendicular skeleton includes the bones of
the front and hind limbs

The Axial Skeleton» The cranium is the portion of the skull that
encloses the brain
![Page 23: SKELETAL SYSTEM](https://reader036.vdocument.in/reader036/viewer/2022062723/56813d5b550346895da7255f/html5/thumbnails/23.jpg)
The Axial Skeleton» The vertebral column
supports the head and body and provides protection for the spinal cord
» The vertebral column is comprised of individual bones called vertebra

The Appendicular Skeleton» Front limb˃ scapula˃ clavicle˃ humerus˃ radius˃ ulna˃ carpal bones˃ metacarpal bones
+ cannon bone in livestock˃ phalanges
