Sutures
Fibrous joints connecting the bone of the brain. Collagen, adding strength and limiting mobility. Close after structural body development is complete, allowing no significant movement.
3 main groups:
- Calvarial sutures
- Facial sutures
- Internal sutures
Calvarial Sutures (9)
Cranial connections between upper skull bones, protecting superior CNS.
- Coronal
- Lambdoidal
- Metopic
- Pterion
- Sagittal
- Squamosal
- Sphenoparietal
- Sphenoquamosal
- Occipitomastoid
Facial Sutures (8)
Connecting bones where facial muscles insert.
- Frontozygomatic
- Frontomaxillary
- Temporozygomatic
- Zygomaticomaxillary
- Sphenofrontal
- Sphenozygomatic
- Nasomaxillary
- Intermaxillary
Name the different Encephalic Regions
Telencephalon
Diencephalon
Mesencephalon
Rhombo-encephalon
Telencephalon
Neocortex, Hippocampus and lateral ventricles.
Newer.
Diencephalon
Subcortical nuclei/structures and third ventricle.
Lower and older.
Mesencephalon
Brainstem and cerebral peduncle (automatic e.g. breathing).
Oldest.
Rhomboencephalon
Cerebellum, pons and medulla. No need for development, remains the same.
