1
Q
Vestibular nucleus
A
- Termination of CN VIII
- Mid Medulla (dorsal aspect next to spinal cord CSF)
2
Q
External or Lateral cuneate nucleus
A
- Relays propreoceperative information to the cerebellum
- Immediately lateral to cuneate nucleus
3
Q
Inferior cerebella peduncle or restiform nucleus
A
- Connects brainstem/spinal cord to the cerebellum
4
Q
Spinal tract of trigeminal
A
- Pain & temperature sensory information, 1st order receptors for CN III.
- Run through the lateral medulla
5
Q
Spinal nucleus of trigminal
A
- Termination of temperature & sensory information from CN III
- Lateral brain stem
6
Q
Anterolateral system
A
- Pain, tempreture & crude touch
- Three ascending pathways
- Spinothalamic tracts
- Spinoreticulotract
- Spinotectal tracts
7
Q
Inferior Olivary Nucleus
A
- Origin of climbing fibers
- Ventral lateral medulla
8
Q
Pyramid
A
- Skilled Motor movements of the contralateral limb
- Vental medulla, containing decussated fibers from the corticospinal tract
9
Q
Medial lemniscus
A
- Well localized touch vibration & joint sensation
- Connection between dorsal column nuclei (cuneate & fasiculus) and the thalamus
- Run through the arcuate fibers
10
Q
Descending sympathetics
A
Dorsal longitudinal faiculatus
11
Q
Nucleus ambiguus
A
- Nucleus for CNX & IX efferent
- Pharyngeal
- Lyrangeal
- Uvula
12
Q
Medial Longitudinal Fasiculus
A
- Horizontal eye movements
- In the midline, ventral to the ventricle sysytem
13
Q
Hypoglossal nucleus
A
- Motor neurons for tounge muscles
14
Q
Dorsal Motor Nucleus of Vagus
A
- Parasympathetic pre-ganglionic neurons for CN X
- Rostral: Inferior salivatory nucleus provides parasympathetics to CN IX
15
Q
Solitary Tract & Nucleus
A
- Visceral sensory neurons for CN X & CN IX go to nucleus. Rostral portion = taste information
