Anatomical Regions and Landmarks of the Human Body
Introduction
Understanding the anatomical regions and surface landmarks of the human body is essential for accurate communication in anatomy and physiology. These terms help describe locations, relationships, and movements of body parts in a standardized way.
Major Body Regions
Cephalic (Head) Region
Frontal: Forehead area.
Orbital: Eye socket region.
Nasal: Nose area.
Buccal: Cheek region.
Oral: Mouth area.
Occipital: Posterior (back) aspect of the head.
Otic: Ear region.
Cervical (Neck) Region
Cervical: Neck area, connecting the head to the trunk.
Trunk (Torso) Regions
Thoracic: Chest region, includes several subregions:
Sternal: Area of the breastbone.
Axillary: Armpit area.
Mammary: Breast region.
Abdominal: Area between the chest and pelvis, contains digestive organs.
Umbilical: Navel (belly button) area.
Pelvic: Lower trunk, below the abdomen.
Inguinal: Groin region, where the thigh meets the trunk.
Pubic: Genital region.
Vertebral: Spinal column area (posterior).
Scapular: Shoulder blade area (posterior).
Lumbar: Lower back, between ribs and hips (posterior).
Sacral: Area between hips, at the base of the spine (posterior).
Gluteal: Buttock region (posterior).
Perineal: Area between the anus and external genitalia (posterior/inferior).
Upper Limb Regions
Acromial: Point of the shoulder.
Brachial: Arm (upper arm, between shoulder and elbow).
Antecubital: Front of the elbow.
Olecranal: Back of the elbow.
Antebrachial: Forearm (between elbow and wrist).
Carpal: Wrist region.
Manus: Hand.
Metacarpal: Back of the hand.
Palmar: Palm of the hand.
Pollex: Thumb.
Digital: Fingers.
Lower Limb Regions
Coxal: Hip region.
Femoral: Thigh (between hip and knee).
Patellar: Front of the knee.
Popliteal: Back of the knee.
Crural: Leg (between knee and ankle, anterior).
Sural: Calf (posterior leg).
Fibular (Peroneal): Lateral side of the leg.
Pedal: Foot.
Tarsal: Ankle region.
Calcaneal: Heel of the foot.
Metatarsal: Top of the foot.
Digital: Toes.
Plantar: Sole of the foot.
Hallux: Big toe.
Body Orientation: Anterior vs. Posterior
Anterior (Ventral): Refers to the front of the body (e.g., chest, abdomen, face).
Posterior (Dorsal): Refers to the back of the body (e.g., back, buttocks, back of the head).
Example: The patellar region is anterior, while the popliteal region is posterior to the knee.

Cervical | Neck | Cervical |
Thoracic | Chest | Sternal, Axillary, Mammary |
Abdominal | Abdomen | Umbilical |
Pelvic | Pelvis | Inguinal, Pubic |
Upper Limb | Arm | Acromial, Brachial, Antecubital, Olecranal, Antebrachial, Carpal, Manus |
Lower Limb | Leg | Coxal, Femoral, Patellar, Popliteal, Crural, Sural, Fibular, Pedal |
Back (Dorsal) | Posterior Trunk | Scapular, Vertebral, Lumbar, Sacral, Gluteal, Perineal |
Additional info:
These anatomical terms are used universally in medicine and biology to avoid confusion when describing locations on the human body.
Knowing these regions is foundational for understanding more advanced topics such as organ systems, clinical examination, and medical imaging.
