1.3 Language of Anatomy Objectives: 1. Become familiar with Anatomical Position. 2. Utilize Anterior & Posterior regional terms correctly. 3. Differentiate between the 3 body planes. 4. Recognize the components of the 2 major body cavities

Anatomical Position  Anatomical position is standing face front, feet together, arms at the sides, with palms facing forward

Directional Anatomy  Directional terms are used to precisely locate one part of the body relative to another and to reduce length of explanations

Directional Terms  Superior/Cephalic/Cranial  Inferior  Anterior/Ventral  Posterior/Dorsal  Superficial: toward surface  Deep: away from surface

Directional Terms  Medial: toward midline  Lateral: away from midline  Proximal: near origin  Distal: away from origin

Regional Terms: Anterior Body Landmarks  Abdominal: Anterior body trunk, inferior to the ribs  Antecubital: Anterior surface of elbow  Axillary: Armpit

Regional Terms: Anterior Body Landmarks  Brachial: Arm  Buccal: Cheek  Cervical: Neck

Regional Terms: Anterior Body Landmarks  Digital: Fingers/Toes  Femoral: Thigh  Inguinal: Where thigh meets body trunk/groin

Regional Terms: Anterior Body Landmarks  Oral: Mouth  Orbital: Eye  Patellar: Anterior Knee

Regional Terms: Anterior Body Landmarks  Pubic: Genital Region  Thoracic: Chest  Umbilical: Navel

Regional Terms: Posterior Body Landmarks  Deltoid: Curve of Shoulder  Gluteal: Buttock  Lumbar: Between ribs & hips (Lower back)

Regional Terms: Posterior Body Landmarks  Occipital: Posterior surface of the head.  Popliteal: Posterior knee area.  Scapular: Shoulder blade region  Sural: Posterior surface of lower leg (calf)

Body Planes & Sections  Sagittal Section: A cut made lengthwise (longitudinal) that divides the body into L & R halves.

Body Planes & Sections  Frontal Section: A cut made lengthwise that divides the body into anterior & posterior parts. (Front & Back)

Body Planes & Sections  Transverse Section: A cut made along a transverse (horizontal) plane, dividing the body into superior & inferior parts (Top & Bottom). AKA cross section.

Body Cavities  Dorsal Body Cavities:  Cranial Cavity: Space inside the body skull.  Spinal Cavity: Extends from the cranial cavity down the vertebral column.

Body Cavities  Ventral Body Cavities  Thoracic Body Cavity: The superior (upper) body cavity that extends down to the diaphragm.  Abdominopelvic Body Cavity:  Abdominal Cavity  Pelvic Cavity

Abdominopelvic Body Cavity
