Contractile vs Non Contractile Part of the muscle: Muscle Tendon Bony insertion Non Contractile Skin Joint capsules ligaments, Fascia Cartilage Dura mater Nerve roots

Your skin First defense to infection and or disease water proof trauma is visually exposed and is called a wound non-contractile

Friction Blister: Moi: continuous rubbing. S/S: fluid, bubble

Skin Bruise MOI: blow, crushing S/S: bleeding

Abrasion MOI: scraping against rough surface. S/S: skin is torn away or reddened

Laceration MOI: tearing S/S: irregularly torn

Skin Avulsion MOI: tearing S/S: tissue is completely ripped from source

Incision MOI: cutting S/S: skin has been sharply cut

Puncture Wound MOI: compression S/S: penetration of skin by sharp object
