Study Notes

Introduction to Anatomy

Anatomy is the study of the structures of the body, divided into two main categories:
- Macroscopic Anatomy: focuses on visible structures without magnification.
- Microscopic Anatomy (Histology): examines cells and tissues using a microscope.

Importance of Studying Anatomy

Understanding anatomy is crucial for:
- Diagnosing and managing diseases.
- Conducting physical examinations and interpreting radiology.
- Performing medical procedures and facilitating communication within medical teams.

Anatomical Position

Defined as standing erect, facing forward, with:
- Upper limbs at sides and palms directed forward.
- Lower limbs together with soles on the ground and toes pointing forward.
All anatomical references for direction and movement are anchored to this position.

Anatomical Planes

Three key geometric planes define body sections:
- Horizontal (transverse): divides body into superior and inferior portions.
- Sagittal: divides body into right and left sides.
- Coronal (frontal): divides body into anterior and posterior sections.

Anatomical Locations

Key terms used to describe anatomical positions:
- Anterior (Ventral) & Posterior (Dorsal): relative to the front and back of the body.
- Superior (Cranial) & Inferior (Caudal): toward the head and away from the head.
- Medial & Lateral: toward the midline and away from the midline.
- Proximal & Distal: closer to or farther from a structure's origin, especially in limbs.
- Superficial & Deep: relative positions compared to the body's surface.
- External & Internal: positions relative to the center of a structure.
- Ipsilateral & Contralateral: positions relative to a reference side of the body.
- Afferent & Efferent: direction of flow relative to a reference point.
- Supine & Prone: positions when lying down, facing upward or downward.
- Palmar & Dorsal: terms used for front and back of the hand.
- Plantar & Dorsal: terms used for front and back of the foot.

Anatomical Movements

Types of movements and their definitions:
- Flexion & Extension: decreases and increases joint angles, respectively.
- Dorsiflexion & Plantar Flexion (foot only):
  - Dorsiflexion lifts the foot's top upward (extension equivalent).
  - Plantar flexion moves the foot's sole downward (flexion equivalent).
- Abduction & Adduction:
  - Abduction moves a body part away from the midline.
  - Adduction moves a body part towards the midline.
- Eversion & Inversion (foot only):
  - Eversion turns the sole laterally.
  - Inversion turns the sole medially.
- Medial & Lateral Rotation:
  - Medial rotation turns anterior surface inward.
  - Lateral rotation turns anterior surface outward.
- Pronation & Supination (forearm):
  - Pronation turns the forearm medially, palm faces posteriorly.
  - Supination turns the forearm laterally, palm faces anteriorly.
- Protraction & Retraction (e.g., jaw):
  - Protraction moves a body part forward.
  - Retraction moves a body part backward.
