ANATOMY:Surface Anatomy and Surface Markings

The subject will be covered under four headings :

.1. core foundational principles

.2. palpable bony landmarks

.3. vital organ projections

.4. clinical application points across all major body regions. 

.1.. Core Examination Techniques

* Visual inspection: Observe general body proportions, skin contours, and superficial muscle bulges.

* Palpation: Feel for underlying bones, tendons, and pulses with firm pressure.

* Percussion and auscultation: Tap or listen to evaluate underlying organ borders and sounds (such as heart and breath sounds).

.2.Palpable Bony Landmarks by Region

* Head and neck: Locate the supraorbital notch, zygomatic arch, and the sternocleidomastoid attachments.

* Thorax and back: Identify the jugular notch, sternal angle (of Louis), and spinous processes of the vertebrae.

* Abdomen: Find the xiphisternum, iliac crests, and anterior superior iliac spines (ASIS).

* Upper and lower limbs: Trace the epicondyles of the humerus, styloid processes of the radius/ulna, greater trochanter, patella, and malleoli. 

.3. Surface Projections of Deep Organs (Surface Markings)

* Cardiovascular system: Map the four classic heart valve listening posts and major vessel pathways (like the common carotid artery).

* Respiratory system: Outline pleural reflections, lung borders, and the thyroid gland.

* Gastrointestinal system: Project the surface anatomy of the liver, spleen, and McBurney’s point for the appendix.

.4. Clinical and Procedural Correlations

* Teach safe zones for intramuscular injections and lumbar punctures.

* Demonstrate sites for emergency access, arterial pulse checks, and nerve block locations.
