Sensory: Head/Face Flashcards
Motor innervation of the facial expression muscles comes from what?
Facial Nerve (CN VII)
Sensory innervation of the face comes from what?
Branches of the Trigeminal Nerve (CN V)
What are the three major branches of the Trigiminal Nerve?
1) Ophthalmic Nerve
2) Maxillary Nerve
3) Mandibular Nerve
Waht is the main sensory distribution of the Ophthalmic Nerve? (CN V1)
Primarily the face and scalp
What is the main sensory innervation of the Maxillary Nerve (CN V2)?
Primarily the cheek and the area lateral to the orbit
What is the main sensory innervation of the Mandibular Nerve (CN V3)?
Primarily the chin and temporal region
What are the subdivisions of the ophthalmic nerve?
1) Supraorbital Nerve
2) Supratrochlear Nerve
3) External Nasal Nerve
4) Infratrochlear Nerve
5) Lacremal Nerve
What are the subdivisions of the Maxillary Nerve?
1) Zygomaticotemporal Nerve
2) Zygomaticofacel Nerve
3) Infraorbital Nerve
What are the subdivisions of the Mandibular Nerve?
1) Auriculaotemporal Nerve
2) Buccal Nerve
3) Mental Nerve
The nerve that supplies the area of the front of the scalp to the vertex of the head.
Supraorbital Nerve
Teh Nere that supplies the external surface of the nose.
External Nasal Nerve
The nerve that supplies the area just medial to teh orbit
Infratrochlear Nerve
The nerve that is characterized as being a small branch just superior to the eye
Lacrimal Nerve
The nerve that supplies a small area just superior to the nose.
Supratrochlear nerve
The nerve that supplies the anterior temporal area.
Zygomaticotemporal Nerve
The nerve that supplies the area just superficial to the zygomatic (cheek) bone.
Zygomaticofacial Nerve
The nerve that supplies the temporal region anterior to the ear
Auriculotemporal Nerve
The nerve that Supplies the skin of the cheek.
Buccal Nerve
The nerve that supplies the chin
Mental Nerve
Teh nerve that is often injured in boxers
Infraorbital Nerve
Which nerve is involved with the condition Bell’s Palsy?
Facial Nerve
Describe Trigeminal Neuralgia.
A condition charecterized by sudden and severe attacks of pain occuring in the distribution fo the trigeminal nerve.
What is often the cause that will increase the condition Tic Douloureux?
Due to any kind of touch to the face, exact cause is truly unknown
What are teh areas that are effected by Trigimenal Neuralgia?
Most Common: Maxillary Division
2nd: Mandibular Division
Least: Ophthalmic Divsion
What nerves innervate the posterior aspect of the neck and scalp?
the posterior/dorsal primary rami of cervical nerves 2,3,4
T/F: C1 has no posterior root carrying sensory fibers, thus is strictly and motor nerve
True
The nerve that supplies the occipital region of the head
Greater Occipital Nerve (from posterior primary ramus of C2)
The nerve that supplies the upper part of the back of the neck.
Third Occipital Nerve (from the posterior primary ramus of C3)
The nerve that supplies the lower part of the back of the neck.
Posterior primary ramus of C4
Where does the sensory innervation of the anterior and lateral aspect of the neck come from?
The anterior/ventral primary rami of C 2,3,4
