Study Notes
Body Planes
- Sagittal Plane: a vertical plane that passes through the center of the body, dividing it into equal right and left halves.
- Frontal Plane (or Coronal Plane): a vertical plane that runs through the center of the body from side to side, dividing the body into front (anterior) and back (posterior) regions.
- Horizontal Plane (or Transverse Plane): a horizontal plane that runs through the midsection of the body, dividing the body into upper (superior) and lower (inferior) regions.
Anatomical Directional Terms
- Superior (cranial): means upward or near the head.
- Inferior (caudal): means downward or near the feet.
- Anterior (ventral): means toward the front (chest side) of the body.
- Posterior (dorsal): means toward the back.
- Medial: means toward the midline of the body.
- Lateral: means away from the midline.
- Ipsilateral: means on the same side.
- Contralateral: refers to opposite sides of the body.
- Proximal: means closest to the point of origin or trunk of the body.
- Distal: means farthest away from the point of origin or trunk of the body.
- Superficial: means toward the body surface.
- Deep: means farthest from the body surface.
- Supine position: lying on the back.
- Prone position: lying face downward.
Terms Related to Movement
- Flexion: brings two parts of the body closer together.
- Extension: means straightening of a joint.
- Dorsiflexion: lifting the foot and toes above the ground.
- Plantarflexion: bending the foot and toes towards the ground.
- Abduction: moving the limb away from the midline of the body.
- Adduction: moving the limb towards the midline of the body.
- Pronation: rotating the forearm medially, so the palmar surface faces posteriorly.
- Supination: rotating the forearm laterally, so the palmar surface faces anteriorly.
- Lateral Flexion: moving the trunk to the right or left.
- Rotation: moving a part of the body around its long axis.
- Circumduction: a circular movement of the distal end of a part, occurring when four movements occur in a sequence (flexion, abduction, extension, and adduction).
- Inversion: moving the foot so the sole faces medially.
- Eversion: moving the foot so the sole faces laterally.
- Protrusion (or Protraction): anterior movement, for example, of the jaw.
- Retrusion (or Retraction): posterior movement, for example, of the jaw.
Human Anatomy
- Human anatomy is the study of structures or body parts and their relationships to one another.
- It is subdivided into Gross Anatomy (macroscopic) and Histology (microscopic anatomy).
- Anatomic terms are essential for accurate communication among medical personnel.
