In Brain 4, you'll deepen the skills you've already studied and have been practicing. You will learn how to work with and release restrictions in several new areas of the brain and spinal cord, especially cranial nerves, nuclei and ganglia, and dorsal root ganglia.

New protocol for the Brain and Spinal Cord
Be sure you understand the following words and, as applicable, know precisely where these structures are located in the body. For this class, it is more important to know the cranial nerve nuclei than the cranial nerve themselves. Pay more attention to cranial nerves XII, XI, X, IX, VII, and V, to the following cranial nerve nuclei: hypoglossal, accessory, dorsal vagal, ambiguus, solitarius, trigeminal (spinal, pontine, mesencephalic), facial and finally to the ganglion of the vagus and trigeminal nerve.
We will also see the choroid plexus, 6-layered cortex, Broca's Area, and Wernicke's area.
Be familiar with the brain structures from each of the following pages of "Netter's Atlas of Human Neuroscience" 1st Edition (2nd Edition in parenthesis):
Page 43-45,58-60 (page 68-73,97-99): Choroid Plexus
Page 44 (page 70-71): facial colliculus, hypoglossal trigone, vagal trigone, vestibular area, gracile and cuneate tubercle.
Page 150-156 (page 220-233): look mainly at the location of the cranial nerve nuclei.
Page 157 (page 234): cranial nerves
Page 158 (page 235-236): cranial nerves nuclei. A very important plate
Page 161 (page 240-241): cranial nerve V
Page 162 (page 243): cranial nerve VII
Page 164 (page 246): cranial nerve IX
Page 165 (page 248-249): cranial nerve X
Page 166 (page 247): cranial nerve XI
Page 167 (page 250): cranial nerve XII
Page 199-201-203 (page 306-310): 6 layered cortex
Page 204 (page 311): cortical areas
Page 222 (page 334): cranial nerve V
Page 223 (page 335): taste pathways
Please Review the Following Notes
This will give you the order and list of cranial nerve nuclei and ganglia we will cover in B4. Try to familiarize yourself with these structures. As usual, you will also have many other easy (and efficient) techniques.
Cranial (and Spinal) Nerves: Overview
"Old Opie Occiput Tries Trigonometry
Very Gloomy, Vague, And Hypoactive"
Old Opie: Olfactory, Optic
Occiput Tries Trigonometry: Oculomotor, Trochlear, Trigeminal
And Feels: Abducens, Facial
Gloomy, Vague, And Hypoactive: Glossopharyngeal, Vagus, Accessory,Hypoglossal
0 - Nervus Terminalis: Reminder
The nervus terminalis lies on the medial side of the olfactory nerve. This nerve is related to reproduction (pheromones) and associated with the vomeronasal organ.
We will not specifically work on this nucleus in B4.
I - II Olfactory - Optic Special sensory nerves
We will not specifically work on these nuclei in B4.
III - Oculomotor (Motor)
- General somatic motor to four extraocular muscles and levator palpebrae superioris muscle
- Visceral motor: intrinsic muscles of the eye.
Parasympathetic nuclei: Edinger-Westphal nuclei. Two functions:
a- Pupillary (iris) constrictor muscle. Action: pupil contraction
b- Ciliary muscle: accommodation of lens, convergence. Action: help to look at closer objects).
The Nucleus of III: is located at the level of the superior colliculi.
Ciliary ganglion (parasympathetic): a flat ganglion located lateral to the optic nerve.
IV - Trochlear (Motor)
OVERVIEW: Strictly somatic motor for the superior oblique muscle
The smallest of the 12 cranial nerves and the only cranial nerve to emerge posteriorly (dorsally) in the brainstem and to be contralateral.
Nucleus of IV: located at the level of the inferior colliculi, inferior to the nucleus of III.
V - Trigeminal (Mixed) (NN221) ("triplet" nerve)
OVERVIEW: Motor for muscles of mastication and 4 other muscles.
General sensory for the cranium, face, and neck, sinus, meninges (anterior 2/3), etc.
The trigeminal is the largest cranial nerve nuclei and the largest ganglion of the CNS.
- GENERAL SENSORY FUNCTIONS: They are three main divisions of the trigeminal nuclei extending throughout the entire brainstem (and the upper part of the spinal cord, as far as C2-C3).
As a simplification:
- THE MESENCEPHALIC NUCLEUS: proprioception, mechanoreceptors for the jaw and teeth.
- THE PONTINE (PRINCIPAL OR CHIEF) SENSORY NUCLEUS: touch (epicritic) and position in space (proprioceptive) sensations
- THE SPINAL (INFERIOR OR CAUDAL) NUCLEUS: pain and temperature (protopathic) information for the face.
The spinal trigeminal nucleus is made up of three parts, from inferior to superior:
- Part caudalis
- Part interpolaris
- Part oralis (with some tactile function).
VI - Abducens (Motor)
OVERVIEW: Strictly motor for the lateral rectus muscle
The Abducens nucleus: is located in the floor of the 4th ventricle.
VII - Facial (Mixed)
1- Branchial motor for muscles of facial expression, and 3 other muscles.
2- Visceral motor for lacrimal, nasal, and salivary glands (except parotid gland).
- Superior salivatory nuclei: Parasympathetic motor impulses
a- pterygopalatine ganglion: lacrimal glands + nasal mucosa
b- submandibular ganglion: submandibular and sublingual glands
3- Taste of anterior 2/3 of the tongue: Nucleus upper (cephalic) part of tractus solitarius. Relay in the Geniculate ganglion (sensory)
4- General sensation for a little area of the external ear, etc.:Spinal nucleus of the trigeminal nerve
VIII - Vestibulocochlear (Sensory)
We already did this nucleus in B3.
IX - Glossopharyngeal (Mixed)
- Branchial motor for one muscle: stylopharyngeus muscle (help swallowing) - Nucleus Ambiguus
- Visceral motor to parotid gland: Inferior Salivatory nucleus (parasympathetic)
- Visceral sensory functions to the carotid body and carotid sinus: Nucleus of the tractus Solitarius, caudal end.
- Taste posterior 1/3 of the tongue (bitter, sour): Nucleus of the tractus Solitarius, cephalic (upper) end.
- General sensation for the posterior 1/3 of tongue, pharynx (participate in "gag" and vomit reflex), tonsil, small area of the posterior ear, Eustachian tube, etc. Spinal trigeminal nucleus.
Glossopharyngeal (IX) Sensory ganglia:
- Superior ganglion or Jugular ganglion: general sensory pathway
- Inferior ganglion or Petrosal or Plexiform: sensory, taste and baroreceptors pathway.
X - Vagus (Mixed) ("wandering" nerve)
- Branchial motor to larynx and pharynx: Nucleus Ambiguus
- Visceral motor to the heart, lungs, and abdominal organs as far as right 2/3 of the colon: Dorsal motor nucleus of the Vagus (preganglionic parasympathetic fibers) + Nucleus Ambiguus
- Visceral sensation from larynx, trachea, esophagus, thoracic and abdominal viscera: Nucleus tractus Solitarius, the caudal end
- Taste posterior of the throat: Nucleus tractus Solitarius, cephalic end
- General sensation for skin of lower pharynx, larynx, posterior meninges, external auditory meatus, a small part of the skin of the external ear, etc.: Spinal nucleus of the trigeminal nerve
Vagus Sensory ganglia (X):
- Superior ganglion or Rostral ganglion: sensory pathway (skin, meninges)
- Inferior ganglion or Nodose ganglion: mainly taste pathway (back of the throat)
XI - Accessory (Mixed)
OVERVIEW: strictly motor for SCM and trapezius muscles
Sternocleidomastoid (ipsilateral) and trapezius (ipsi or contralateral).
There is a long spinal root (from C1-C5) and a small cranial root (nucleus ambiguus) for this nerve.
XII - Hypoglossal (Motor)
OVERVIEW: Strictly motor, intrinsic & extrinsic muscles of the tongue (except the palatoglossus muscle innervated by X).
We will also work on:
- Spinal Nerve Ganglia (or Dorsal Root Ganglia = DRG)
- Periaqueductal Gray matter (PAG)
