Overview
This lecture covers the key anatomical regional terms for identifying various parts of the human body, dividing them into axial and appendicular regions.
Major Body Regions
- The body is divided into the axial region (head, neck, trunk) and the appendicular region (upper and lower limbs).
- Axial region includes head, neck, and trunk areas; appendicular region includes limbs and their attachments.
Axial Region: Head and Neck
- Cephalic region: entire head.
- Cranial region: skull.
- Frontal region: forehead.
- Ocular region: eyes.
- Otic region: ears.
- Nasal region: nose.
- Buccal region: cheeks.
- Oral region: mouth.
- Mental region: chin.
- Occipital region: back/base of the skull.
- Cervical region: neck.
Axial Region: Trunk
- Thoracic region: chest area between neck and abdomen.
- Axillary region: armpits.
- Mammary region: breasts.
- Sternal region: area over the sternum.
- Abdominal region: abdomen; can be divided into quadrants or regions.
- Umbilical region: navel or belly button.
- Pelvic region: area between hip bones.
- Inguinal region: groin, site of inguinal hernias.
- Pubic region: external genitalia area.
- Perineal region: area between genitals and anus.
- Dorsal region: back.
- Vertebral region: along the spine.
- Lumbar region: lower back.
- Sacral region: near the sacrum bone.
- Gluteal region: buttocks.
Appendicular Region: Upper Limbs
- Acromial region: shoulder.
- Brachial region: upper arm.
- Antecubital region: front of the elbow.
- Olecranal region: back of the elbow.
- Antebrachial region: forearm.
- Carpal region: wrist.
- Manual region: hand.
- Metacarpal region: area beyond the wrist.
- Palmar region: palm.
- Pollex region: thumb.
- Digital region: fingers.
Appendicular Region: Lower Limbs
- Coxal region: hip.
- Femoral region: thigh.
- Patellar region: kneecap/front of knee.
- Popliteal region: back of knee.
- Crural region: front of the leg (shin).
- Sural region: calf/back of the leg.
- Pedal region: foot.
- Calcaneal region: heel.
- Tarsal region: ankle.
- Metatarsal region: area beyond the ankle.
- Hallux region: big toe.
- Digital region: toes.
- Plantar region: sole of the foot.
