Study Notes
Anatomical Divisions and Terminology
- Sagittal plane divides the body into left and right halves.
- Transverse plane separates the body into upper and lower portions.
- Frontal (or lateral) plane divides the body into anterior (front) and posterior (back) sections.
Body Orientation and Position
- Posterior refers to the back or rear side of the body.
- Anterior denotes the front side of the body.
- Superior means a position higher or above another part.
- Inferior refers to a position lower or below another part.
- Medial indicates a position closer to the midline of the body.
- Lateral describes a position farther away from the midline.
- Proximal pertains to a position closer to the point of attachment or origin.
- Distal refers to a position farther away from the point of attachment or origin.
- Central denotes a position closer to the center or core of the body.
- Superficial describes a position closer to the surface of the body.
Movements and Actions
- Prone refers to a position lying face down.
- Supine describes a position lying face up.
- Abduction involves moving a limb away from the midline of the body.
- Adduction means moving a limb toward the midline.
- Flexion refers to decreasing the angle between body parts.
- Extension involves increasing the angle between body parts.
- Hyperextension means extending a body part beyond its normal range of motion.
- Internal rotation pertains to rotating a limb towards the body's midline.
- External rotation refers to rotating a limb away from the body's midline.
- Circumduction involves circular movement of a body part.
- Pronation refers to the inward rotation of the forearm or foot.
- Dorsiflexion involves lifting the foot upwards at the ankle.
- Plantar pertains to the sole of the foot.
Neural Terminology
- Afferent relates to incoming sensory signals to the central nervous system.
- Efferent refers to outgoing signals from the central nervous system to muscles or glands.
Anatomical Positioning
- Anatomical position is a standard reference posture: standing upright, facing forward, arms at the sides, with palms facing forward.
