Anatomy Terms
Orientation and DirectionOrientation and Direction
Superior – towards head Superior – towards head
Inferior (caudal) – towards the lower part of a body partInferior (caudal) – towards the lower part of a body part
Anterior (ventral) – frontAnterior (ventral) – front
Posterior (dorsal) – backPosterior (dorsal) – back
Medial – toward the midline of the bodyMedial – toward the midline of the body
Lateral – Away from the midlineLateral – Away from the midline
Intermediate – between a more medial and lateral position Intermediate – between a more medial and lateral position (center)(center)
Proximal – Closer to the origin of the body Proximal – Closer to the origin of the body partpart
Distal – closer to the end of the body partDistal – closer to the end of the body part
Superficial – Toward the body surfaceSuperficial – Toward the body surface
Deep – Away from the body surfaceDeep – Away from the body surface
Body Planes, Sections, and Cavitites
Body planes
Body is 3DBody is 3D
Can be split into three Can be split into three planesplanes
SagittalSagittal CoronalCoronal Transverse Transverse
Sagittal Plane Plane splitting the body Plane splitting the body
into two parts (left and into two parts (left and right)right)
Sagittal section is a cut Sagittal section is a cut made longitudinally along made longitudinally along the bodythe body
If it splits into two equal If it splits into two equal parts = midsagittalparts = midsagittal
Coronal Plane
Plane which splits Plane which splits body into anterior and body into anterior and posterior sectionposterior section
Transverse Plane
Separates body along Separates body along horizontal planehorizontal plane
Also called a cross Also called a cross sectionsection
Will divide an Will divide an organism into superior organism into superior and inferior partsand inferior parts
Body Cavities
Cavities
Opening within body Opening within body which protects internal which protects internal organs, and allows organs, and allows transfer of transfer of materials/informationmaterials/information

Made up of two smaller Made up of two smaller cavitiescavities
1) 1) Cranial CavityCranial Cavity – – holds and protects brainholds and protects brain
2) 2) Spinal CavitySpinal Cavity – – column which runs column which runs through vertebra and through vertebra and protects spinal chordprotects spinal chord
Ventral Cavities Divided into two smaller Divided into two smaller
cavitiescavities
1) Thoracic – chest area 1) Thoracic – chest area (holds heart, lungs, and (holds heart, lungs, and diaphragm)diaphragm)
2) Abdominopelvic – lower 2) Abdominopelvic – lower torso (holds digestive and torso (holds digestive and reproductive organs)reproductive organs) Subdivided into Subdivided into
