AN1.1-2 | Anatomical terminology — Summary & Reflection

REFLECT

Take a moment and do the following on yourself:
1. Stand in anatomical position. Feel the difference between the anterior and posterior surface of your forearm.
2. Pronate your forearm (palm down). Supinate it (palm up). Which position are you in right now as you hold this device?
3. Palpate your sternum. This flat bone contains red marrow — the factory producing your blood cells right now.
4. What is one thing from this session that surprised you? Write it down in your logbook.

KEY TAKEAWAYS

Key Takeaways — Anatomical Terminology (AN1.1 and AN1.2)

1. Anatomical position: body upright, palms forward — the universal reference point for all anatomical descriptions
2. Three body planes: Sagittal (right/left), Coronal/Frontal (front/back), Transverse (up/down) — remember SCT
3. Directional pairs: Superior/Inferior, Anterior/Posterior, Medial/Lateral, Proximal/Distal, Superficial/Deep
4. Movements in planes: Flexion/Extension (sagittal), Abduction/Adduction (coronal), Rotation (transverse)
5. Special movements: Pronation/Supination (forearm), Dorsiflexion/Plantar flexion (ankle), Inversion/Eversion (foot)
6. Bone composition: ~35% collagen (flexibility) + ~65% hydroxyapatite (hardness) — like reinforced concrete
7. Bone marrow types: Red marrow (haematopoiesis, in spongy bone) and Yellow marrow (fat storage, in medullary cavity)
8. Adaptive conversion: Yellow marrow reverts to red marrow under haematopoietic stress
