Integumentary System
The Integumentary System is composed of Skin and accessory Organs such as hair, nails, and Cutaneous Glands
Largest Organ!
Skin weighs about six pounds and sheds every 27 days Integumentary Cont.
Functions of skin
• Works to waterproof body (Keratin, a fibrous protein aids in this)
• Acts as a cushion and protects body from infection
• Excretes waste
• Regulates Temperature and prevents dehydration by controlling perspiration
• Houses sensory receptors to detect pain, sensation, and pressure
• Storage of water, fat, glucose, and Vit. D
Skin
Three Layers of Skin
Epidermis
• Top layer (Only a tenth of a millimeter …show more content…
Types of Bone Fractures
Avulsion
• A muscle or ligament pulls on the bone, fracturing it
Comminuted
• Bone is shattered into many pieces
Compression
• Generally occurs in the spongy bone of the spine, for example a portion of the vertebra in the spine may collapse due to osteoporosis
Fracture Dislocation
• A joint becomes dislocated, and one of the bones of the joint has a fracture
Bone Fractures Cont.
Greenstick Fracture
• Bone partly breaks on one side, but not completely. More common in children whose bones are softer and more elastic.
Impacted
• When bone is fractured, one fragment of bone goes into another Longitudinal
• Along the length of bone
Oblique
• Diagonal to a bones long axis Spiral
• A fracture where at least one part of the bone has been twisted
Bone Fractures Cont.
Stress
• Breaks due to repeated stress and strains
Transverse
• Straight break right across …show more content…
• Irritates the articular cartilage and synovial membrane
• It usually attacks only one joint at a time
• It most often strikes the joint of the big toe
Summary
There are many different diseases and disorders of the skin, bones, and joints. I tried to give a brief description of each system and point out a few of the common disorders!
I hope you enjoyed my presentation!
You are my favorite teacher!
A&P IS AWESOME!!
