The head, neck and spine pack more named structures per square centimetre than any other region of the body: 22 skull bones, 12 pairs of cranial nerves, 7 cervical vertebrae, 33 vertebrae in total, and a tangle of arteries, veins, muscles and glands squeezed in between. The Flip It deck Medical Anatomy: Head, Neck and Spine (deck code TF0791, 100 cards) turns that tangle into a fixed order you can drill in about 20 minutes a day.

Sample cards from the deck

FrontBack
Axis (C2)The second cervical vertebra with a projection (dens or odontoid process) that allows rotation of the head
Foramen magnumThe large opening at the base of the skull through which the spinal cord passes
How many vertebrae are in the human vertebral column?33: 7 cervical, 12 thoracic, 5 lumbar, 5 sacral (fused), 4 coccygeal (fused)
Three branches of the trigeminal nerveOphthalmic, maxillary and mandibular nerves
Sphenoid boneA complex butterfly-shaped bone forming part of the base and sides of the skull
Carotid sinusA dilated area at the carotid bifurcation containing baroreceptors that monitor blood pressure
Brachial plexusA network of nerves formed from C5-T1 spinal nerves that innervate the upper limb
Muscles of masticationMasseter, temporalis, medial pterygoid and lateral pterygoid
Bell's palsyTemporary weakness or paralysis of facial muscles due to dysfunction of the facial nerve
Lambdoid sutureThe suture between the occipital bone and the parietal bones

What the 100 cards cover

  • Skull: frontal, parietal, temporal, occipital, sphenoid and ethmoid bones; mandible, maxilla, zygomatic and nasal bones; coronal, sagittal and lambdoid sutures; paranasal sinuses; cranium vs. face.
  • Spine: atlas (C1), axis (C2), dens, transverse foramina, cervical/thoracic/lumbar vertebrae, sacrum, coccyx, intervertebral discs, vertebral canal, kyphosis, lordosis, scoliosis, herniated disc, cervical spondylosis.
  • Nerves: 12 cranial nerve pairs, facial nerve (CN VII), trigeminal nerve (CN V), cervical nerves, 31 pairs of spinal nerves, cervical plexus (C1-C4), brachial plexus (C5-T1).
  • Vessels: internal and external carotid arteries, vertebral arteries, common carotid bifurcation, carotid sinus, internal and external jugular veins.
  • Muscles: sternocleidomastoid, trapezius, scalenes, platysma, masseter, temporalis, orbicularis oculi, orbicularis oris, frontalis.
  • Neck viscera and CNS: thyroid, parathyroids, larynx, pharynx, trachea, esophagus, meninges, cerebrospinal fluid, blood-brain barrier, brainstem, cerebellum, occipital lobe.
  • Clinical: stroke, whiplash, torticollis, trigeminal neuralgia, macrocephaly, cervical lymphadenopathy, lumbar puncture (L3-L4 or L4-L5).

Two tips specific to this region

1. Drill the skull as pairs and singles. Of the eight cranial bones, the parietal and temporal bones come in pairs; frontal, occipital, sphenoid and ethmoid are single. Once that split is fixed, the sutures follow logically: coronal (frontal-parietal), sagittal (parietal-parietal), lambdoid (occipital-parietal). Say the two bones out loud each time a suture card comes up.

2. Link every nerve card to a clinical card. The deck pairs naturally: facial nerve with Bell's palsy, trigeminal nerve with trigeminal neuralgia, vertebral arteries with the transverse foramina they pass through, carotid bifurcation with the carotid sinus. When you flip one, recall the partner before revealing the answer. That is how these facts are tested in practice: a symptom, then the structure behind it.

Study plan

Split the deck into three blocks: bones and sutures (cards 1-40), vertebrae and nerves (41-60), then muscles, vessels, viscera and pathology (61-100). One block per session, previous block reviewed first; spaced repetition brings back the cards you hesitate on. The full 100 fits in a week.
