Study guide: Introduction to Anatomy

📋 Course Outline

1. Purpose and Anatomical Position
2. Body Planes and Axes
3. Directional Anatomical Terms
4. Movements of the Body

📖 1. Purpose and Anatomical Position

🔑 Key Concepts & Definitions

• Anatomy: the study of body structure and the relationships between its parts
• Anatomical position: standing with the feet parallel, facing forwards, the arms by the sides, and the palms facing forwards

★ Must-know

• A good knowledge of anatomical terms enables healthcare providers to communicate accurately nationally and internationally.

• Anatomical knowledge allows healthcare providers to describe the exact location of normal or diseased body parts and record abnormalities.

Further detail

• Anatomical knowledge is required for surgical intervention.

💡 Memory Hook

Stand upright, face forward, arms by the sides, palms forward.

📖 2. Body Planes and Axes

🔑 Key Concepts & Definitions

• Sagittal plane: divides the body into right and left halves
• Coronal plane: divides the body into front and back parts
• Transverse plane: divides the body into upper and lower parts

📝 Essential Points

• The coronal plane moves around a sagittal axis, the transverse plane moves around a vertical axis, and the sagittal plane moves around a coronal axis.

💡 Memory Hook

Planes divide the body; axes describe the rotation around which movement occurs.

📖 3. Directional Anatomical Terms

🔑 Key Concepts & Definitions

• Anterior and posterior: Anterior means toward or in front of the body, whereas posterior means toward or behind the body.
• Medial and lateral: Medial means closer to the midline, whereas lateral means further away from the midline.
• Superior and inferior: Superior means above or on top of another structure, whereas inferior means below or underneath it.
• Proximal and distal: Proximal means nearer to the trunk, whereas distal means further from the trunk.
• Superficial and deep: Superficial means closer to the body surface, whereas deep means further from the body surface.

💡 Memory Hook

Medial is toward the midline, whereas lateral is away from it.

📖 4. Movements of the Body

🔑 Key Concepts & Definitions

• Flexion and extension: Movement of a body part forwards is generally called flexion, whereas movement backwards is generally called extension.
• Abduction and adduction: Movement of a body part away from the midline is generally called abduction, whereas movement toward the midline is called adduction.
• Rotation: Rotation outwards is called lateral or external rotation, whereas rotation inwards is called medial or internal rotation.
• Supination and pronation: Supination rotates the arm so that the palm faces up, whereas pronation rotates the arm so that the palm faces down.
• Inversion and eversion: Inversion turns the sole of the foot inward toward the midline, whereas eversion moves the sole away from the midline.
• Circumduction: Circumduction combines the four movements described in the course and produces a circular movement of a limb.
• Dorsiflexion and plantar flexion: Dorsiflexion involves standing on the heel, whereas plantar flexion involves standing on the toes.

💡 Memory Hook

Inversion turns the sole inward, whereas eversion turns it outward.
