Document Summary
Cranial nerves: 12 pairs of cranial nerves in humans learning objectives: list the 12 cranial nerves by name and number identify where each cranial nerve originates and terminates, state the functions of each cranial nerve. Can be both sensory and motor olfactory superior part of nasal cavity. Have 20-30 olfactory nerve fibres on each olfactory nerve/synapse/bulb. Olfactory nerves act differently to other nerves: synapsing= joing up with other nerves. + colds and smoking gives decrease in senses. + get smell back which means they regenerate. Cn i: olfactory n representation of fibres projecting though cribiform plate and synapsing in olfactory bulb. Why we need to draw stuff in through breathing in through nose to smell something. 3 nerves involved in extrinsic and intrinisic of eye: 5 out of 7 muscle in green lateral view of eye in through superior orbital fissure goes to intrinsic muscle arounf pupil.
