1 Introduction to Anatomy

2 Purpose of Anatomy Foundation of many healthcare professions Foundation of many healthcare professions ATC must have excellent understanding of anatomy ATC must have excellent understanding of anatomy What structures have been injured What structures have been injured What constitutes normal movement What constitutes normal movement

3 Anatomical Position Improves communication between healthcare professionals  standard body alignment Improves communication between healthcare professionals  standard body alignment Erect stance, arms at side, palms facing forward Erect stance, arms at side, palms facing forward

4 Planes of the Body Frontal plane: vertical plane, divides body into front & back halves Frontal plane: vertical plane, divides body into front & back halves Sagittal plane: vertical plane, divides body into left & right sides Sagittal plane: vertical plane, divides body into left & right sides Transverse plane: horizontal plane, divides body into upper & lower parts Transverse plane: horizontal plane, divides body into upper & lower parts

5 Common Medical Terms of Location Anterior: towards the front Anterior: towards the front Posterior: towards the back Posterior: towards the back Medial: toward the midline Medial: toward the midline Lateral: away from the midline Lateral: away from the midline Proximal: towards an attachment (shoulder or hip) Distal: away from an attachment Superior: above another point Inferior: below another point

6 Movements Flexion: bending of joint (↓ angle between 2 bones) Flexion: bending of joint (↓ angle between 2 bones) Extension: straightening of joint (↑ angle between 2 bones) Extension: straightening of joint (↑ angle between 2 bones) Hyperextension: extending beyond normal range of motion Hyperextension: extending beyond normal range of motion

7 Movements—con’t Abduction: limb moves away from midline Adduction: limb moves toward midline

8 Movements—con’t Rotation: bone moves on axis, toward or away from the body Rotation: bone moves on axis, toward or away from the body Circumduction: limb moves in circular path around axis Circumduction: limb moves in circular path around axis CircumductionRotation

9 Movements—con’t Supination: turning palm upward; raising medial margin of foot Supination: turning palm upward; raising medial margin of foot Pronation: turning palm downward; lowering medial margin of foot Pronation: turning palm downward; lowering medial margin of foot

10 Movements—con’t Plantarflexion: extends the foot, toes pointing down Dorsiflexion: flexes the foot, toes pointing up

11 Movements—con’t Inversion: turns sole of the foot inward Inversion: turns sole of the foot inward Eversion: turns sole of the foot outward Eversion: turns sole of the foot outward

12 Movements—con’t Protraction: body part glides forward (shoulder, jaw) Protraction: body part glides forward (shoulder, jaw) Retraction: body part glides backward Retraction: body part glides backward ProtractionRetraction

13 Movements—con’t Elevation: lifting body part upward (shoulders) Depression: lowering body part downward DepressionElevation

14 Movements—con’t Opposition: movement of the thumb to touch each finger Opposition: movement of the thumb to touch each finger

15 Axis of Rotation ALL movements occur around an axis of rotation ALL movements occur around an axis of rotation Each plane has an axis that runs perpendicular to the plane Each plane has an axis that runs perpendicular to the plane
