Chapter 1 Introduction to Anatomy Do Now Take a few to review for the Terminology quiz Anatomical position • To avoid confusion among medical professional an anatomical position has been established. It is an erect stance with arms to the side palms facing forward and head forward. Terms of position & direction Anatomical planes Medical term for locations • Anterior-refers to the front of the body • Posterior refers to the back of the body Medial and Lateral Medial-closer to the midline Lateral-away from the midline M M L L Do Now • Draw a knee and identify the following on it. • Anterior • Medial • Lateral Proximal Situated nearer to the center of the body, a point of attachment or midline of body. Ex. Shoulder is proximal to the elbow Ex. Hip is proximal to the knee Distal Away from the center of the body or point of attachment Cranial/Superior Closer To the Head/Cranium, or Above Caudal/Inferior •Closer to the feet •Lower part of body Do Now • Draw a foot like picture Identify the following anatomical locations: • Distal-D • Posterior-P • Medial-M • Lateral-L Anatomical position worksheet Do Now • Write down this definition: Palmar-is the directional location for the palm of the hand. Movements •Flexion( ) -bending of hinge joint •Extension( / )straightening of hinge joint •Abduction( Abd)-Away from the midline •Adduction (Add)toward the midline Pronation(pron)- palm down for wrist Inward lean of forefoot for ankle Orthotics This is how orthotics work • Do Now-copy this in notes Supination(sup)-palm up for wrist •Outward lean of forefoot for ankle Supination •Inversion(Inv)sole is inward •Eversion(Ev)sole is outward • Protraction (protract)shoulders forward • Retraction(retract -shoulders back • Internal rotation(Int. R)rotating toward the body External rotation (Ext.R)-rotating away from the body Circumduction(circum.) • Happens at the ball and socket joint and encompasses several movements. Plantarflexion(PF)pointing ankle Dorsiflexion(DF)-ankle up Lateral flexion(Lat. – )to the side Horizontal Abduction (Horiz.Abd) and Horizontal Adduction(Horiz.Add) HORIZONTAL ADDUCTION HORIZONTAL ABDUCTION
