- Afferent connection arrives and an efferent connection exits.

Carotid sheath contents

I See (I.C.) = Internal Carotid artery 10 = CN 10 (Vagus nerve) CC = Common Carotid artery IV = Internal Jugular Vein I See 10 CC's in the IV

Cavernous sinus contents

O TOM are lateral wall components, in order from superior to inferior. CA are the components within the sinus, from medial to lateral. CA ends at the level of T from O TOM. Occulomotor nerve (III) Trochlear nerve (IV) Ophthalmic nerve (V1) Maxillary nerve (V2)

Diaphragm apertures: spinal levels

- Aortic hiatus = 12 letters = T12 Oesophagus = 10 letters = T10 Vena cava = 8 letters = T8 I ate 10 eggs at 12: I = IVC ate = T8

Duodenum: lengths of parts

Lateral geniculate nucleus

- A simple mnemonic for remembering this is "See I? I see, I see," with "see" representing the C in "contralateral," and "I" representing the I in "ipsilateral." Another is "Emily and Pete meet eye to eye" as in "M and P meet I to I," or again, Magno and Parvo meet Ipsi to Ipsi. Another way of remembering this is 2+3=5, which is correct, so ipsilateral side, and 1+4 doesn't equal 6, so contralateral.
