Study Notes

Anatomical Terms and Positions

Anatomical Position: Body is upright, feet slightly apart, palms facing forward with thumbs outward.
Superior (Cranial): Indicates a location toward the head or upper body, such as the head being superior to the abdomen.
Inferior (Caudal): Refers to a position toward the lower part of the body; an example is the navel being inferior to the chin.
Ventral (Anterior): Describes positions at the front of the body; for instance, the breastbone is anterior to the spine.
Dorsal (Posterior): Refers to locations at the back of the body, as seen where the heart is posterior to the breastbone.
Medial: Indicates a position toward the midline of the body; the heart is medial to the arm.
Lateral: Points away from the midline; for example, the arms are lateral to the chest.
Intermediate: Denotes a location between a more medial and a more lateral structure, such as the collarbone being intermediate between the breastbone and shoulder.
Proximal: Closer to the body part's origin or the limb's attachment point; for instance, the elbow is proximal to the wrist.
Distal: Farther from the origin or attachment point; the knee is distal to the thigh.
Superficial (External): Refers to locations toward the body surface, like the skin being superficial to the skeletal muscles.
Deep (Internal): Indicating a position away from the body surface; the lungs are deep to the skin.
Directional Terms: Essential for explaining the positions of body structures in relation to one another.

Body Parts and Planes

Axial Part: Comprises the main axis of the body, including the head, neck, and trunk.
Appendicular Part: Includes limbs or appendages attached to the body's axis.
Regional Terms: Designate specific areas within major body divisions for clarity in location.
Sagittal Plane: A vertical plane dividing the body into right and left segments.
Median Plane (Midsagittal Plane): A sagittal plane exactly along the midline of the body.
Parasagittal Planes: Offsets from the midline, representing all other sagittal planes.
Frontal (Coronal) Plane: Vertically divides the body into anterior and posterior parts.
Transverse (Horizontal) Plane: Divides the body into superior and inferior parts through a horizontal cut; also known as a cross-section.
Oblique Sections: Diagonal cuts between horizontal and vertical planes; not commonly used.

Body Cavities

Dorsal Body Cavity: Protects nervous system organs, consisting of the cranial cavity and vertebral (spinal) cavity.
Ventral Body Cavity: Houses internal organs (viscera), divided into the thoracic and abdominopelvic cavities.
Thoracic Cavity: Superior portion of the ventral cavity, encased by ribs and chest muscles; includes pleural cavities (for lungs) and the mediastinum (containing the heart).
Abdominopelvic Cavity: Contains two parts: the superior abdominal cavity (stomach, intestines, etc.) and the inferior pelvic cavity (urinary bladder, reproductive organs, rectum).
