Simple hand-drawn medical diagram for MBBS students showing linear skull fracture (fissured fracture). Black pen sketch style on white paper. Show a top-down view of a skull with a single straight or slightly curved crack line running across the parietal bone. Label: "Linear / Fissured Fracture". Add small arrows showing blunt force from a broad surface. Include a small note: "Most common - 70% of skull fractures". Simple, clean, like a student's notebook diagram.

Simple hand-drawn medical diagram for MBBS students showing depressed skull fracture (signature fracture). Black pen sketch style on white paper. Show a cross-section view of skull with outer table pushed inward, inner table shattered more, bone fragments driven into cranial cavity. Draw a hammer above with impact arrow. Label: "Depressed Fracture = Fracture à la Signature". Add note: "Outer table driven into diploe; inner table comminuted". Simple notebook-style sketch.

Simple hand-drawn medical diagram for MBBS students showing basilar skull fracture. Black pen sketch style on white paper. Show a lateral view of skull base with fracture line at the base. Include two sub-diagrams: (A) Anterior fossa fracture - periorbital ecchymosis "Raccoon eyes" and CSF rhinorrhoea; (B) Posterior fossa fracture - Battle's sign behind ear and CSF otorrhoea. Label each clearly. Add note about which cranial nerves affected. Simple medical student notebook style.

Simple hand-drawn medical diagram for MBBS students showing diastatic skull fracture (sutural fracture). Black pen sketch style on white paper. Show a top-down view of a skull with fracture line running along and opening up a suture (sagittal suture shown). Draw widening gap between parietal bones. Label: "Diastatic Fracture - opening of suture line". Add note: "Common in children; sagittal suture most common; seen in child abuse". Arrows showing separation. Simple notebook-style sketch.

Simple hand-drawn medical diagram for MBBS students showing comminuted skull fracture (mosaic / spider web fracture). Black pen sketch style on white paper. Show a top-down view of skull with multiple radiating fracture lines from a central impact point, surrounded by circular fracture lines forming a spider web or mosaic pattern. Label: "Comminuted / Mosaic / Spider-web Fracture". Arrow showing heavy localized impact. Note: "Multiple fragments; severe local impact". Clean notebook-style sketch.

Simple hand-drawn medical diagram for MBBS students showing ring fracture of skull. Black pen sketch style on white paper. Show a bottom-up (base of skull) view with a circular/ring-shaped fracture line around or near the foramen magnum in the posterior cranial fossa. Draw arrows going upward from feet/heels showing force transmitted up the spine. Label: "Ring Fracture - around Foramen Magnum". Note: "Fall from height on feet; force transmitted up spine". Simple medical student notebook style.

Simple hand-drawn medical diagram for MBBS students showing pond fracture of skull. Black pen sketch style on white paper. Show a cross-section of infant skull with a smooth concave depression - like a table-tennis ball pressed inward - but NO fracture lines in the bone. Bone is bent/indented without breaking. Label: "Pond Fracture - Ping-pong ball fracture". Note: "Only in infants; pliable bones; no actual fracture line; depression without break". Simple notebook-style sketch.
