Olfactory nerve controls what sense?
Sense of smell(sensory nerve)
Optic nerves control what sense?
Sight(sensory nerve)
Oculomotor nerves control what movement?
Movement of the eyes… For the eyeballs to look up & down
Trochlear nerve controls?
Movement of the eyeballs downward & inward {crossed eye}
Ophthalmic nerve controls
Sensory info from the cornea
Scalp
Nose
& face
Maxillary nerve controls
Sensory info from the cheeks
Upper lip
And teeth
Mandibular nerve controls
Chewing
Abducens control.
Movement of the eyeballs
Facial nerves
Mixed nerves containing both sensory and motor nerves. Controls facial expressions 2/3 of the taste from the tongue
Vestibulochlear nerve controls
Hearing and balance from the inner ear
Vagus is a mixed nerve that?
Carries info from throat & esophagus and others to the brain. Helps in swallowing by controlling the throat & salivary glands
Accessory nerve controls?
Muscles that move the throat, neck and voice box
Hypoglossal nerve controls
The movement of the tongue (helps in speech)
Cervical plexus controls
The movement of the neck and shoulders
Brachial nerve
Contains 5 different nerves
- axillary nerve– runs thru the armpit
- medial nerve– runs thru the wrist if damaged
leads to carpal tunnel
Lumbar plexus
Contains 2 important nerves
– Siatic nerve– goes thru lower back gluteus and back of legs– responsible for pain in lower back
– Femoral nerve– from lower back to front of legs
Coccygeal plexus
Runs thru the tail bone
If damaged takes very long time to get rid of
Glossopharyngeal nerve
Mixed nerves that send info from throat &aback of tongue to the brain for interpretation
Controls the muscles of the throat
Involved in swallowing
