Sem2Mini1 Anatomy

• Dorsal root ganglia;
• Sympathetic ganglia; Medulla of suprarenal gland
• Preaortic ganglia
• Enteric ganglia in wall of the gut tube.
• Leptomeninges (Pia and Arachnoid;)
• Glial cells;
• Schwann cells; Conotroncal septum of the heart; Odontoblasts;
• Melanocytes; as well as connective tissue and several bones of face and skull

Dorsal horn, under BMP forming sensory areas of the spinal chord

Ventral horn, under SHH forming the motor areas of the spinal chord

Sulcus limitan

• Above the tenorium (anterior and posterior cranial fossae and flax cerebra) via V1 and v2
• Middle cranial fossa = V3
• belwo the tentorium is the CN X and IX

Anterior closure by mid 4th week and posterior by late 4th week

Failure of the Choroid fissure to close, produces a dark notch ( cleft) within the Iris

Cerebellum and pons

medulla

Brain white/grey, corpus callosum, internal capsule, olfactory bulb

• Hypothalamus
• Dorsal thalamus
• Third ventricle

• Premature sagittal suttre closure
• long head like "alien"

• Premature closure of coronal suture
• fat wide head like hammer head

• Brain herniation out of badly formed skull like in spine
• meningocele-->menigoencephalocele-->meneingohydroencephalocele

• frontal skull bone median suture that disappears in adults
• sometimes resistant to mimic a fracture

• wide and large sutures while you are a baby
• posterior closes by 3-6 month after birth
• anterior closes around middle of second year (becomes the bregma)

CSF flow from lateral ventricles into the 3rd and 4th ventricle respectively
