Term
What is the olfactory nerve, what type of neurons does it have, and what are the neurons for?
Definition
Cranial nerve I, sensory only, smell.
Term
What is the optic nerve, what types of neurons does it have, and what are those neurons for?
Definition
Cranial nerve II, sensory neurons only, for vision.
Term
What nerve is the oculomotor nerve?
Definition
Cranial nerve III.
Term
What nerve is the trochlear nerve?
Definition
Cranial nerve IV.
Term
What nerve is the abducens nerve?
Definition
Cranial nerve VI.
Term
How do cranial nerves III, IV, and VI work together, what types of neurons, and what are the neurons for?
Definition
These nerves deal with sensory and motor neurons, sensory neurons are for eye proprioception, motor neurons are for extrinsic eye muscles and eye movement.
Term
What nerve is the trigeminal nerve, what types of neurons are involved, what are those neurons for?
Definition
Cranial nerve V, sensory neurons for proprioception/touch/pain/temperature from most of face, motor neurons for chewing.
Term
What nerve is the facial nerve, what types of neurons are involved, and what are those neurons for?
Definition
Cranial nerve VII, sensory neurons for input from most of scalp/face/neck, motor neurons for facial expressions/taste sensations.
Term
What nerve is the vestibulocochlear nerve, what types of neurons are involved, and what are they for?
Definition
Cranial nerve VIII, sensory neurons for balance and hearing.
Term
What nerve is the glossopharyngeal nerve, what types of neurons are involved, and what are those neurons for?
Definition
Cranial nerve IX, sensory neurons for tase sensations, motor neurons to secrete saliva.
Term
What nerve is the vagus nerve, what types of neurons are involved, and what are those neurons for?
Definition
Cranial nerve X, sensory neurons for visceral sensation/proprioception, motor neurons for parasympathetic motor signals to heart/bronchial passages/GI tract/gallbladder.
Term
What nerve is the accessory nerve, what types of neurons are involved, and what are those neurons for?
Definition
Cranial nerve XI, sensory neurons for proprioception, motor neurons for swallowing and head movements.
Term
What nerve is the hypoglossal nerve, what types of neurons are involved, and what are those neurons for?
Definition
Cranial nerve XII, sensory neurons for tongue proprioceptors, motor neurons for tongue muscles/speech/swallowing.
