Nerves

C3, 4, 5, keep the diaphragm alive

The phrenic nerve, which innervates the diaphragm, originates in spinal nerves C3, C4, and C5.

S2, 3, 4, keep the penis off the floor

S2-S4 give rise to the pudendal nerve, which supplies the penis and other pelvic structures.

Ooh, ooh, ooh, to touch and feel very good velvet. AH!

Cranial nerves in order:

1. Olfactory
2. Optic
3. Oculomotor
4. Trochlear
5. Trigeminal
6. Abducens
7. Facial
8. Vestibulococchlear
9. Glossopharyngeal
10. Vagus
11. Accessory
12. Hypoglossal

Some lovers try positions that they can't handle

Carpals, from first digit (thumb) to fifth (pinkie):

• Distal row:
  • Scaphoid
  • Lunate
  • Triquetrum
  • Pisiform
• Proximal row:
  • Trapezium
  • Trapezoid
  • Capitate
  • Hamate

Notes:

• Pisiform is anterior to the triquetrum
• The mnemonic has two Ts in a row, which might make it difficult to remember which comes first (trapezium or trapezoid). Luckily, they're in alphabetic order.

Before sex, get latex condoms

Layers of the epidermis (deep to superficial):

• Stratum basale (germinivatum)
• Stratum spinosum
• Stratum granulosum
• Stratum lucidum
• Stratum corneum

Some anatomists like freaking out poor medical students.

Branches of external carotid artery (roughly inferior to superior):

1. Superior thyroid a.
2. Ascending pharyngeal a.
3. Lingual a.
4. Facial a.
5. Occipital a.
6. Posterior auricular a.
7. Maxillary a.
8. Superficial temporal a.

Point and shoot.

Erection and ejaculation in males.

• Erection ("pointing") is parasympathetically mediated
• Ejaculation ("shooting") is a sympathetic event
