What is surface anatomy?
The study of EXTERNAL FEATURES OF THE BODY, that can be visualised without dissection.
What are the features you should be able to locate on yourself/each other?
ON THE HEAD
- Mastoid Process
- Nasal Bones and Nasal Cartilages
- Zygomatic Arch
- Angle of Mandible
ON THE NECK
- Hyoid Bone
- Thyroid and Cricoid Cartilage
- Sternocleidomastoid Muscle
- C7 Vertebrae Spinous Processes
ON THE THORAX
- Manubriosternal Joint
- Nipples
- Costal Margin
- Intercostal Spaces
ON THE ABDOMEN
- Umbilicus
ON THE UPPER LIMB
- Biceps Tendon
- Medial Epicondyle, Ulnar Nerve and Olecranon
- Head of Ulna
- Radial Artery at the Wrist
- Thenar Eminence
ON THE LOWER LIMB
- Iliac Crest
- Greater Trochanter
- Tibial Tuberosity
- Anterior (Subcutaneous) Tibia
- Medial and Lateral Malleoli
- Calcaneum and Achilles Tendon
What are the features of the head that you need to identify?
- Mastoid process
- Nasal bones and nasal cartilages
- Zygomatic arch
- Angle of mandible
Identify the mastoid process on yourself

What is the clinical relevance of the mastoid process?
- Site of bruising in basal skull fractures (aka battle’s sign)
- Common site of bacterial infection (mastoiditis)
What is the site of bruising in basal skull fractures (of the mastoid process) known as?
Battle’s sign
What is battle’s sign?
Site of bruising in basal skull fractures (mastoid process)
The mastoid process is a common site of …?
Bacterial infection
What is mastoiditis?
Bacterial infection of the mastoid process (it is a common site of bacterial infection)

What does this image show?
Site of bruising in basal skull fractures (aka Battle’s Sign)
Fig. 6 (bottom right)
What does this picture show?
Common site of bacterial infection of the mastoid process (mastoiditis)
Identify the nasal bones and nasal cartilages on yourself
Nasal Bone - superior, firm part of external nose
Nasal Cartilage - inferior, soft part of external nose
Fig. 8
Label the nasal bone and nasal cartilage
Nasal Bone - superior, firm part of external nose
Nasal Cartilage - inferior, soft part of external nose
Where is the nasal bone?
SUPERIOR, firm part of external nose
What is the superior, firm part of external nose?
Nasal bone
What is the nasal cartilage?
INFERIOR, soft part of external nose
What is the inferior, soft part of external nose?
Nasal Cartilage
Fig. 8
Label the image
- Frontal bone
- Nasal bones
- Frontal process of maxilla
- Lateral process of septal nasal cartilages
- Septal cartilage
- Minor alar cartilage
- Accessory nasal cartilage
- Lateral crus of major alar cartilage
- Medial crus of major alar cartilage
- Septal nasal cartilage
- Anterior nasal spine of maxilla
- Alar fibrofatty tissue
- Infraorbital foramen
- Nasal Bone - superior, firm part of external nose
- Nasal Cartilage - inferior, soft part of external nose
What is the clinical relevance of the nasal anatomy?
If someone is having a nosebleed (epistaxis), press on the nasal cartilage NOT the nasal bone.
What is epistaxis?
Nosebleeds
What is the medical term for nosebleeds?
Epistaxis
Where should you hold the nose to prevent epistaxis?
On the nasal cartilage, NOT the nasal bone.
What is the zygomatic arch?
‘cheek bone’
