Study Notes

Anatomy

The study of the structure of the body
Derived from the Greek word "Anatome" meaning "to dissect or cut apart"

Anatomical Position

Upright stance with arms straight and hands by hips, palms facing forward
Feet parallel with toes pointing forward

Supine Position

Body lying flat on the back

Prone Position

Body lying flat on the front with face downwards

Anatomical Planes

Median (Sagittal) Plane: Vertical plane that divides the body into equal right and left halves
Paramedian (Parasagittal) Plane: Any vertical plane parallel to the median plane dividing body into unequal right and left parts
Coronal Plane: Vertical plane dividing the body into anterior and posterior parts
Horizontal (Transverse) Plane: Divides the body into upper and lower parts

Directional Terms

Medial: Towards the median plane
Lateral: Away from the median plane
Superior (Cranial): Towards the head
Inferior (Caudal): Towards the feet
Proximal: Close to the point of origin or trunk
Distal: Away from the point of origin or trunk
Intermediate: Between two structures
Anterior (Ventral): Towards the front of the body
** Posterior (Dorsal):** Towards the back of the body
Superficial: Towards the surface of the body
Deep: Away from the surface of the body
Ipsilateral: On the same side of the body
Contralateral: On the opposite side of the body

Anatomical Terms of Movement

Abduction: Moving a limb away from the midline
Adduction: Moving a limb towards the midline
Rotation: Turning a limb around its long axis:
- Medial Rotation: Ventral surface moves towards the midline (pronation in the forearm)
- Lateral Rotation: Ventral surface moves away from the midline (supination in the forearm)
Flexion: Decreasing the angle between two body parts
Extension: Increasing the angle between two body parts
Dorsiflexion: Extension at the ankle joint
Plantar Flexion: Flexion at the ankle joint
Inversion: Moving the sole of the foot inwards
Eversion: Moving the sole of the foot outwards
Elevation: Moving a body part upwards
Depression: Moving a body part downwards
Protraction: Moving a body part forward
Retraction: Moving a body part backwards
Circumduction: A circular movement combining flexion, abduction, extension, and adduction

Anatomical Regions

Head
Neck
Trunk:
- Thorax
- Abdomen
- Pelvis & External Genitalia
Extremities:
- Upper Limb:
  - Shoulder Joint
  - Arm
  - Elbow Joint
  - Forearm
  - Wrist Joint
  - Hand
  - Fingers
- Lower Limb:
  - Gluteal Region
  - Hip Joint
  - Thigh

Skin

Largest organ in the body
Epidermis: Outer layer of stratified squamous epithelium
Dermis: Underlying connective tissue containing sweat glands, hair follicles, sebaceous glands, blood vessels, lymphatics, and nerves
Subcutaneous Fat: Layer beneath the dermis

Fascia

Connective tissue beneath the skin
Superficial Fascia: Loose connective tissue beneath the skin, thicker in the trunk than limbs
Deep Fascia: Condenses fibrous tissue that forms membrane beneath the superficial fascia, surrounds muscles, and forms septa between muscles

Deep Fascia

Forms aponeuroses for protection in palms and soles
Thickens around distal joints (e.g., wrist and ankle) to form retinacula
Absent in specific regions like the face and anterior abdominal wall
