towards the back of the organism
ventral
towards the front
medial
towards the midline
lateral
away from the midline
deep
towards the center or inside
ipsilateral
on the same side
contralateral
on the opposite side
coronal
like a crown - in the plane from ear to ear
sagittal
down the center of the head (like a part in your hair)
grey matter
nucleus - collection of cell bodies in CNS

ganglion - collection of cell bodies in periphery
peduncle
band of neurons connecting parts of brain

CNS - tract
PNS - nerve
sulcus (sulci)
groove(s)
fissure
deep groove
gyrus (gyri)
bump(s)
fugal
away from
ex: corticofugal = away from cortex
afferent
towards: refers to incoming info/neuronal process

= sensory
efferent
eminating from; referes to outgoing info/neuronal processes

= motor
telencephalon
forebrain, cerebral hemisphere
diencephalon
thalamus and related structures
mesencephalon
midbrain
metencephalon
pons and cerebellum
myelencephalon
medulla and spinal cord
Primary sensory cell of visual system
bipolar cell
secondary order cell of visual system
retinal ganglion cell
1st visual synapse
retina
where does the visual system cross the midline?
optic chiasm
1st synapse of dorsal column medial lemniscus
medulla
1st synapse of spinothalamic tract
dorsal horn
2nd order cell of visual system
retinal ganglion cell
2nd order cell of dorsal column medial lemniscus
dorsla column = gracile nucleus & cuneate nucleus
2nd order cell of spinothalamic tract
spinal cord
What is the function of the corticospinal tract?
stimulates the motor neurons in the spinal cord that are responsible for moving the body's axial muscles, as well as the arms and legs.
Lateral Corticospinal Tract
contains the axons of the cortical neurons that are responsible for the muscles of the extremities
Ventromedial Corticospinal Tract
begins in the cortical motor neurons that control the body's axial muscles

ventromedial system does not change sides when it enters the spinal cord -- descends fairly directly to ventral and medial part of spinal cord -- connects to motor neurons
Red Nucleus
Rostral midbrain nucleus involved in motor function

lies in the midbrain, just dorsal to the substantia nigra, at the level of the superior colliculus

DEFICIT = motor problems of contra arm and leg
What information does the dorsal column system convey?
touch, vibration, concious proprioception
What happens when there is a lesion involving a dorsal root ganglion?
interuption in information from/to dermatome
