Study Notes
Introduction to Anatomy
- Anatomy is the study of structures and their relations within the body
- The word "anatomy" originates from the Greek word "anatome," meaning "cutting up."
Fields of Anatomy
- Gross Anatomy: Examination of visible structures with the naked eye.
- Surface Anatomy: Study of the projection of internal body parts onto the body's external surface.
- Radiological Anatomy: Uses X-rays, CT scans, and MRIs to visualize the internal structure of the body.
- Developmental Anatomy (Embryology): Focuses on prenatal developmental changes occurring in an individual.
Approaches to Studying Anatomy
- Regional Approach: Each region of the body (e.g., head & neck, upper limb, lower limb, thorax, abdomen & pelvis) is studied separately, considering all aspects (muscles, nerves, bones, vasculature, and viscera).
- Systemic Approach: Each system is studied separately and traced throughout the body. For example, the cardiovascular system analyzes the heart and all blood vessels.
Anatomical Positions
- Standard or Erect Anatomical Position: Body standing erect, facing forward, eyes looking straight, feet slightly apart, palms facing forward, thumbs pointing away from the body, and legs fully extended.
- Supine Position: Body lying down, face pointing upwards.
- Prone Position: Body lying horizontally, face directed downwards.
- Lateral Position: Body lying on either the right or left side.
Anatomical Planes & Lines
- Median or Sagittal Plane: Divides the body vertically into equal right and left halves.
- Parasagittal Plane: Vertical plane parallel to the median plane, dividing the body into unequal right and left halves.
- Coronal or Frontal Plane: Divides the body vertically into anterior and posterior halves (front and back, ventral and dorsal).
- Transverse Plane: Horizontal plane dividing the body into superior and inferior halves (upper and lower).
- Oblique Plane: Any plane other than the above described planes.
Anatomical Terms
- Anterior (Ventral): Towards the front.
- Posterior (Dorsal): Towards the back.
- Superior (Cranial): Towards the head.
- Inferior (Caudal): Towards the feet.
- Medial: Towards the median plane (near the middle of the body).
- Lateral: Away from the median plane (away from the middle of the body).
- Ipsilateral: Structures lying on the same side of the body.
- Contralateral: Structures lying on opposite sides of the body.
- Superficial or External: Near the body surface or skin.
- Deep or Internal: Towards the core of the body.
Anatomical Terms of the Limbs
- Proximal: Structure closer to the trunk.
- Distal: Structure further away from the trunk.
- Flexor Surface: Anterior surface of the upper limb and posterior surface of the lower limb.
- Extensor Surface: Posterior surface of the upper limb and anterior surface of the lower limb.
Terms Describing Movements
- Flexion: Decreasing the angle of a joint by bringing flexor surfaces closer.
- Extension: Increasing the angle of a joint by approximating extensor surfaces.
- Adduction: Movement towards the median plane (e.g., moving the upper limb towards the trunk).
- Abduction: Movement away from the median plane (e.g., moving the upper limb away from the trunk).
- Medial Rotation: Rotation towards the median plane (inward rotation).
- Lateral Rotation: Rotation away from the median plane (outward rotation).
- Circumduction: Combined movements of flexion, extension, adduction, and abduction in a circular manner.
- Elevation: Raising a body part towards the head.
- Depression: Lowering a body part towards the feet.
- Protrusion: Forward movement of a body part.
- Retraction: Backward movement of a body part.
- Pronation: Medial rotation of the forearm, causing the palm to face backwards.
- Supination: Lateral rotation of the forearm, causing the palm to face forwards.
- Opposition: Bringing the thumb and little finger together.
- Reposition: Moving the thumb and little finger away from each other.
- Inversion of Foot: Moving the plantar surface of the foot medially (inwards).
- Eversion of Foot: Moving the plantar surface of the foot laterally (outwards).
- Dorsiflexion: Extension at the ankle, pointing the foot superiorly.
- Plantar Flexion: Flexion at the ankle, pointing the foot inferiorly.
