Study Notes
Anatomical Position
- Standing straight, legs close together, feet parallel, toes forward.
- Arms at sides, palms facing forward, head up, gazing straight ahead.
Anatomical Planes
- Median Plane: Vertical, divides body into right and left halves.
- Sagittal Planes: Vertical, variable placement, divides body into unequal left and right parts.
- Frontal (Coronal) Planes: Vertical, perpendicular to sagittal planes, separates front from back.
- Transverse (Horizontal) Planes: Horizontal, divides body into upper and lower parts.
Body Sections
- Longitudinal Sections: Cut along the longitudinal axis.
- Transverse Sections (Cross Sections): Perpendicular to longitudinal axis, show relative internal structures.
- Oblique Sections: Diagonal cuts, not aligned to any defined plane.
Anatomical Direction Terms
- Superior: Towards the head (e.g., chest is superior to the hip).
- Inferior: Towards the feet (e.g., hip is inferior to the chest).
- Cranial/Caudal: Cranial = towards the head, Caudal = towards the tail/feet.
Anterior and Posterior
- Anterior/Ventral: In front (e.g., nose is anterior to the forehead).
- Posterior/Dorsal: Behind (e.g., back is posterior to the chest).
Medial and Lateral
- Medial: Closer to the midline (e.g., eyes are medial to ears).
- Lateral: Farther from the midline (e.g., ears are lateral to eyes).
Internal and External
- Internal: Closer to the center of an organ (e.g., heart is internal).
- External: Further from the center (e.g., ribs are external).
Superficial and Deep
- Superficial: Closer to the surface (e.g., skin is superficial to muscles).
- Deep: Below the surface (e.g., muscles are deep to the skin).
- Intermediate: Between superficial and deep structures.
Proximal and Distal
- Proximal: Closer to the trunk (e.g., thigh is proximal to foot).
- Distal: Farther from the trunk (e.g., foot is distal to thigh).
Terms of Laterality
- Unilateral: Found on one side (e.g., spleen).
- Bilateral: Paired structures on both sides (e.g., lungs).
- Ipsilateral: Same side (e.g., left arm and left leg).
- Contralateral: Opposite sides (e.g., left and right hands).
Movements Definitions
- Flexion: Decreases angle between body parts; bending (e.g., knee flexion).
- Extension: Increases angle between body parts; straightening.
Specialty Movements
- Dorsiflexion: Flexion of the foot upwards.
- Plantarflexion: Flexion of the foot downwards.
Abduction and Adduction
- Abduction: Movement away from the midline (e.g., arms spreading sideways).
- Adduction: Movement towards the midline.
Circumduction and Rotation
- Circumduction: Circular motion, proximal end fixed.
- Rotation: Moving around an axis (e.g., shaking head).
Pronation and Supination
- Pronation: Palm facing down; radius rotates medially.
- Supination: Palm facing up; radius rotates laterally.
Body Positions
- Supine Position: Lying on back, face up.
- Prone Position: Lying on abdomen, face down.
Foot Movements
- Eversion: Sole of foot moves laterally.
- Inversion: Sole of foot moves medially.
Opposable Thumbs
- Opposition: Thumb touches fingers; crucial for gripping.
- Reposition: Thumb returns to anatomical position.
Protrusion and Retrusion
- Protrusion: Anterior movement (e.g., tongue sticking out).
- Retrusion: Posterior movement (e.g., tongue retracting).
Scapular Movements
- Protraction: Shoulder blades move forward.
- Retraction: Shoulder blades move backward.
Elevation and Depression
- Elevation: Superior movement (e.g., shrugging shoulders).
- Depression: Inferior movement (e.g., lowering shoulders).
