Anatomical Planes of the Human Body

Anatomical Planes Defined p. 14 Fig. 1. 11 § Saggital (median) Plane – lengthwise cut of the body into right and left sides; if passes along midline, then body is in equal parts = median § Transverse (horizontal) plane – cut that divides body into superior and inferior portions § Coronal (frontal) plane – divides body into anterior and posterior views.

Anterior and Posterior view

Anterior and Posterior Positions § Anterior – § means towards the front § Posterior – § opposite view of anterior; means toward the back

Superior and Inferior Views

Superior and Inferior Views Superior – § means the body part is above another part or is closer to the head. Inferior – § means the body part is below another part or is closer to the feet

Medial and Lateral Views

Medial and Lateral Medial § relates to an imaginary midline dividing the body into equal left and right halves. Body part is medial if it is close to the midline. (Nose is medial to the eyes) Lateral – § means toward the side with respect to the imaginary midline (Ears are lateral to the eyes)

Proximal and Distal Views

Proximal and Distal Proximal – § describes a body part that is closer to a point of attachment than another body part. (Elbow is proximal to the wrist) Distal – § opposite of proximal; particular body part is farther from a point of attachment than another body part. (Fingers are distal to the wrist)

Superficial and Deep Superficial – § situated near the surface Deep – § parts that are more internal

Body Views Axial Portion – head, neck, trunk § Dorsal cavity – cranial cavity and vertebral canal § Ventral Cavity – Thoracic cavity, Diaphragm, abdominopelvic cavity Appendicular Portion – arms & legs

Body Cavities Lateral View

Body Cavities cranial cavitiy – § houses the brain vertebral canal – § spinal cord and some vertebrae

Body Cavities Thoracic cavity – Lungs and more § Mediastinum region (separates right and left lungs) = heart, esophagus, trachea, and thymus Diaphragm – § separates the thoracic from the abdominopelvic

Body Cavities § abdominopelvic cavity – § Abdominal cavity – stomach, liver, spleen, gallbladder, kidneys, most of the small and large intestines § Pelvic cavity – enclosed by hip bones; includes terminal portion of large intestine, urinary bladder, and internal reproductive organs.
