Anatomy Regional Terms, Directional Terms, and Body Planes

Vocabulary flashcards covering human anatomical regions, directional terms, and body planes/sections based on the provided lecture notes.

Anatomical Position

The standardized structural position of the body used as a reference point in anatomical terminology.

Cephalic

Pertaining to the head region, encompassing cranial, facial, frontal, orbital or ocular, otic, buccal, nasal, oral, and mental subdivisions.

Cranial (Anatomical Region)

The upper part of the head enclosing the brain, forming a subdivision of the cephalic region.

Facial

The anterior face portion of the cephalic region.

Frontal

The forehead region of the cephalic area.

Orbital or Ocular

Pertaining to the eye region within the cephalic area.

Otic

Pertaining to the ear region within the cephalic area.

Buccal

Pertaining to the cheek region of the face.

Nasal

Pertaining to the nose region of the face.

Oral

Pertaining to the mouth region of the face.

Mental

Pertaining to the chin region of the face.

Cervical

Pertaining to the neck region.

Trunk

The main body region exclusive of the head and limbs, divided into thoracic, abdomen, and pelvis sections.

Thoracic

The chest region of the trunk, which includes the mammary region.

Mammary

Pertaining to the breast area within the thoracic region.

Abdomen

The main middle region of the trunk containing the umbilical area.

Umbilical

Pertaining to the area around the navel in the abdomen.

Pelvis

The inferior portion of the trunk, containing the inguinal and pubic regions.

Inguinal

Pertaining to the groin area located within the pelvis region.

Pubic

Pertaining to the genital region located within the pelvis.

Axillary

Pertaining to the armpit region.

Brachium

Pertaining to the arm (upper arm) region.

Antebrachium

Pertaining to the forearm region.

Cubital

Pertaining to the posterior elbow region.

Antecubital

Pertaining to the front or anterior surface of the elbow.

Superior & Inferior

Directional terms indicating higher/above (towards the head) versus lower/below (towards the feet).

Anterior & Posterior

Directional terms indicating towards the front (ventral) versus towards the back (dorsal) of the body.

Cranial & Caudal

Directional terms indicating towards the head/upper end versus towards the tail/lower end of the body axis.

Dorsal & Ventral

Directional terms indicating towards the back/spine versus towards the belly/front.

Directional Terms (Biped vs Quadruped Alignment)

Diagram illustrating how directional axes differ between bipeds and quadrupeds: in bipeds, superior aligns with cranial and inferior with caudal, while anterior aligns with ventral and posterior with dorsal. In quadrupeds, superior aligns with dorsal and inferior with ventral, while anterior aligns with cranial and posterior with caudal.

Proximal & Distal

Directional terms indicating nearer to the origin or point of attachment versus farther from the origin or point of attachment.

Medial & Lateral

Directional terms indicating closer to the midline of the body versus farther away from the midline.

Superficial & Deep

Directional terms indicating closer to the surface of the body versus farther internal/away from the surface.

Sagittal Plane

A vertical plane that divides the body or an organ into left and right sides.

Midsagittal (median) Plane

A specific sagittal plane passing directly through the midline, dividing the body into equal right and left halves.

Parasagittal plane

A sagittal plane that does not pass through the midline, dividing the body into unequal left and right sides.

Frontal plane (or Coronal)

A vertical plane dividing the body or organ into anterior (front) and posterior (back) portions.

Horizontal plane (or Transverse)

A plane dividing the body or organ into superior (top) and inferior (bottom) portions.

Oblique

A plane or section that passes through the body or organ at an angle between horizontal and vertical planes.
