Study Notes
Introduction to Human Anatomy
- Anatomy is the oldest medical science
- The word "anatomy" is derived from the Greek word "anatome," meaning "cutting up"
- Anatomy is the study of the structures of the body and their relationships.
Objectives
- Understand basic anatomical terminology
- Describe the anatomical position of the body
- Know different anatomical planes and terms of positions
- Know different anatomical planes and terms of movements
Fields of Anatomy
- Gross Anatomy: Study of visible structures to the naked eye
- Surface Anatomy: Study of projections of internal body parts on the external surface of the body
- Radiological Anatomy: Study of anatomy using imaging techniques like X-rays, CT scans, and MRIs
- Developmental Anatomy (Embryology): Study of prenatal developmental changes in an individual
Approaches to Study Anatomy
- Regional Approach: Studying each region of the body (head, neck, upper limb, etc.) at the same time
- Systemic Approach: Studying each body system (nervous, circulatory, respiratory, etc.) throughout the entire body
Anatomical Positions
- Standard anatomical position: Body erect, facing forward, feet slightly apart, palms facing forward, thumbs pointing away from the body, and legs fully extended
- Supine position: Lying down, face upward
- Prone position: Lying down, face downward
- Lateral recumbent position: Lying on the side (right or left)
Anatomical Planes and Lines
- Median (sagittal) plane: Divides the body into equal right and left halves
- Parasagittal plane: Divides the body into unequal right and left halves, parallel to the median plane
- Coronal (frontal) plane: Divides the body into anterior (front) and posterior (back) portions
- Transverse plane: Divides the body into superior (upper) and inferior (lower) portions
- Oblique plane: Any plane that is not parallel to the above planes
Anatomical Terms
- Anterior (ventral): Toward the front
- Posterior (dorsal): Toward the back
- Superior (cranial): Toward the head
- Inferior (caudal): Toward the feet
- Medial: Toward the midline of the body
- Lateral: Away from the midline of the body
- Ipsilateral: On the same side of the body
- Contralateral: On the opposite side of the body
- Superficial: Toward/on the surface of the body
- Deep: Away from the surface of the body
Anatomical Terms of the Limbs
- Proximal: Nearer to the trunk
- Distal: Farther from the trunk
- Flexor surface: Anterior surface of the upper limb, posterior surface of the lower limb
- Extensor surface: Posterior surface of the upper limb, anterior surface of the lower limb
Terms Describing Movements
- Flexion: Decreasing the angle between two bones
- Extension: Increasing the angle between two bones
- Abduction: Movement away from the midline
- Adduction: Movement toward the midline
- Medial rotation: Rotation toward the midline
- Lateral rotation: Rotation away from the midline
- Circumduction: Movement in a circular motion
- Elevation: Movement upward
- Depression: Movement downward
- Protrusion: Movement outward (forward)
- Retraction: Movement inward (backward)
- Pronation: Medial rotation of the forearm (palm faces backward)
- Supination: Lateral rotation of the forearm (palm faces forward)
- Opposition: Bringing thumb and little finger together
- Reposition: Returning thumb and little finger to their extended position
- Inversion: Turning the sole of the foot inward
- Eversion: Turning the sole of the foot outward
- Dorsiflexion: Bending the foot upward at the ankle
- Plantar flexion: Bending the foot downward at the ankle
